Roof-Pro’s PP-3 riser penetration units have been used to provide watertight pipe and cable entry points into the building at Tonyrefail School near Cardiff, South Wales.

As part of a project worth £44 million, the school was delivered under the auspices of the Welsh government’s 21st century schools programme. It’s one of a number of ‘super school’ education projects to be delivered in Wales as part of an initiative to improve education in local areas, and all have to be delivered within a tight timescale to meet the target.

After discovering Roof-Pro, an Alumasc company, online and finding many positive reviews of similar work, Boyes Rees Architects chose to specify Roof-Pro roof service entry units as they are capable of dealing with larger circular duct sizes of 600mm and above, whilst still remaining watertight.

The PP-3 puts the waterproofing’s durability first in its design – for quick installation into the waterproofing membrane. Its design also encompasses easy access features, a powder coated aluminium finish for durability and cover flashing deep enough to permit vertical insulation.

Roof-Pro were also able to accommodate the client’s tight timescale and conducted the site visit, issued drawings for approval and delivered all products to site on time.

Roof-Pro’s Regional Technical Manager Jimi Ogunsola, who worked with Boyes Rees Architects to find the right product for the project, explained: “The Roof-Pro PP-3 access riser was perfect for this project, providing a watertight entry point to run larger roof-mounted cables, ducts and pipes into your building safely—a consistent, quality solution for necessary penetrative details on flat roofs.

“The design allows M&E trades easy access to run cables and pipes. Once installed, the building is immediately dry, and following trades can fully access the riser by temporarily removing the lid.”

Mark Harries of Whitehead Building Services, the contractor who worked on the project said: “Alumasc were a pleasure to work with for this project; communication was extremely important given the fast approaching deadline but all went smoothly.

“Even when we found ductwork and capping that had been installed already were not sufficiently watertight, airtight nor adequately insulated, we were able to communicate effectively and put plans in place to ensure that the extra work would not disrupt the timescale.”  

Mark went on to say: “We found Roof-Pro products very durable, and easy to install. They provide great value for money by offering a second-to-none watertight seal and excellent quality, which just can’t be substituted.”

An exclusive new housing development in the heart of London is the latest showcase for a range of waterproofing and green roof solutions from Alumasc.

Built by The Berkeley Group in the centre of Belgravia, the elite Ebury Square development offers a selection of one to four bedroom private residences.

Alumasc’s Registered Contractor Tilbury Contracts Ltd, installed a total of 3,800m² of Hydrotech monolithic membrane to the lightwell areas, podium roofs, individual balconies, wraparound terraces and penthouse balconies, which were all completed as inverted roof designs.  A Hydrotech anti-root waterproofing system, inverted roof insulation, drainage boards, extensive green roof substrates and sedum mats were also installed to the main roof areas. The courtyard was waterproofed and insulated and a drainage board installed providing support for the construction of deep planters, raised areas and stairways creating attractive landscaped gardens and protection for the car park below.

The project presented a major challenge in that it is situated directly over a London Underground route. The concrete slab at ground level was mounted on large anti-vibration springs, and isolated from the surrounding construction to prevent damage to the building from the vibration of trains below.  The resulting 50mm joint between the isolated and non-isolated structures, required appropriate waterproofing to prevent water entry into the basement below.

Working together, Alumasc and Tilbury Contracts strapped the joint using FlexFlash UN, an uncured neoprene rubber, with the full Hydrotech 6125 system abutting the joint edge on both sides to ensure it was watertight whilst also keeping the two slabs isolated. A brick upstand was built directly off the Hydrotech, and the full system was dressed from the previously waterproofed horizontal slab and up the face of the brickwork, and terminated with a cover flashing. This ensured successful waterproofing whilst not compromising the integrity of the specified system.

Richard Sawyer, construction and surveying manager with Tilbury Contracts, said:

“The roofing installation for the project was completed on time and to budget and has helped provide a sophisticated and desirable place for people to live in the heart of Belgravia.  The use of Hydrotech and the Blackdown green roofing system from Alumasc complemented the build perfectly – Hydrotech is a very secure system which is easy to work with and suited the awkward detailing better than any alternative product would have. The green roof is not only visually pleasing but provides strong environmental credentials whilst offering additional benefits such as noise insulation.”

Alumasc’s Hydrotech is a hot melt system which provides seamless waterproofing ideal for high performance green roofs, podiums and highly detailed waterproofing or water feature schemes. It is manufactured using a minimum of 10% post-consumer recycled material, is BBA accredited and has European Technical Approval.

Blackdown Green Roofs from Alumasc are constructed from a range of components that replicate the natural growing environment for plants, without requiring the same depth and weight of construction.

A Blackdown green roof from Alumasc provides one of the main features at the new School of Architecture and Construction at The University of Greenwich.

Officially opened in December 2014, the £78m new-build development is based in Stockwell Street within Maritime Greenwich on the UNESCO World Heritage Site. The project also included a new library, and features a series of terraced roofs, comprising 14 interlinked teaching gardens, forming the largest multifunctional roof space in London.

To facilitate this pioneering green roof design, a total of  3,407m² of green roofing System from Alumasc was specified by architects, Heneghan Peng, and Landscape Architects Allen Scott, and installed by Blackdown.

The new building had to be ‘demonstrably sustainable’ in the sense that both it, and its facilities, minimise their environmental impact and use of resources. The Blackdown green roof system creates a living laboratory where the sustainability of new ideas in landscape and architecture can be tested, and innovations developed and applied.

Glenn O’Brien, Architect at Heneghan Peng, commented:
“Our design proposals had to reflect the location’s status as a UNESCO World Heritage site while remaining sensitive to the neighbouring buildings, particularly the residences to the rear of the site. Incorporating the interlinked landscaped roofs allowed us a creative approach in dealing with these challenges.

“The green roof system underpins all of the landscaping on the roofs. We see it as the base infrastructure that allows for either soft or hard landscaping permutations. This proved very useful as the design progressed with different planting options, and we were secure in the University of Greenwich knowledge that the green roof system would be able to accommodate them. The zero-fall system also allowed us to achieve very large spans and roof areas with minimum difficulty.

“There is naturally a great deal of excitement about the future of research at the University of Greenwich and these roofs are already helping students and staff to extend their understanding of environmental infrastructure and of landscaped and green spaces across increasingly urbanised areas.”

The 14 interlinked terraces have already been received a BREEAM Innovation award due to their educational and research aims. Blackdown green roofs from Alumasc are constructed from a range of components that replicate the natural growing environment for plants, without requiring the same depth and weight of construction.

Green roofs absorb CO₂, improve a building’s thermal performance, increase rainwater retention thereby reducing storm water run-off, and reduce the life-cycle costs of a roof by protecting it from climatic changes, UV light and mechanical damage.

Alumasc Roofing Systems along with Mitie Tilley Roofing have recently completed the installation of a 1500 m² Derbigum high performance waterproofing system at Crown Bevcan, Carlisle.  Crown, UK beverage can manufacturers and one of the largest packaging companies in the world, were investing £2 million into the upgrade of their production line at Botchery.

As the 3rd highest producer of beverage cans globally and with net sales in 2014 of $9.1 billion, it was essential that Crown had peace of mind that any refurbishment works carried out at their Botchery plant would result in the waterproofing integrity of their works being guaranteed long term. To this end, Alumasc Roofing were approached to provide a waterproofing system that could be installed with this key aim in mind.

Richard Emerson, Alumasc Roofing Area Manager and the Alumasc Technical Team worked very closely with the Client and Mitie Tilley Roofing to ensure the waterproofing solution specified met the demanding requirements of this project and site conditions.

Challenges:

The most challenging aspect of the project was to keep the site live with no interruption to the production process. This was overcome with thorough planning and organisation. The Client, Mitie Tilley Roofing and Alumasc worked closely to facilitate site deliveries at timed intervals and coordinate site inspections to strict time schedules.

Design Considerations:

Communication was key with this scheme and attention to detail was paramount. The existing building required a robust and versatile waterproofing system to upgrade the manufacturing office, yet the aesthetics of the original building had to be taken into account.

Allied to these requirements, the waterproofing specified had to have superior performance characteristics in relation to the prevention of external fire spread and penetration.

The Derbigum Solution

Taking all these factors into account, Derbigum was the natural choice not only due to its ‘unrestricted’ classification in relation to fire, but also the Alumasc 30 Year Insurance Backed Warranty offered for this project.  The Derbigum system provided superior performance and waterproofing longevity for the future of their works.

Derbigum is a BBA approved system, with a life expectancy in excess of 30 years.  It is suitable for flame-free and cold application to warm roofs with metal, concrete or plywood decks and inverted roofs with concrete decks.

Alumasc’s ZinCo green roof system and Hydrotech structural waterproofing were key elements in the EcoCampus at Hamilton International Park, a uniquely sustainable business community located south east of Glasgow.

Built by Balfour Beatty, the EcoCampus is designed to provide a sustainable foundation delivering high performance buildings with EPC & BREEAM ‘Carbon Neutral’ & ‘Excellent’ Status. The EcoCampus accommodates businesses within three Grade A carbon neutral buildings totalling 223,800 square feet.

The ZinCo intensive green roof system features planter zones, small plants, shrubs and bushes and was an important part of the development’s environmental focus. Briggs Amasco installed the green roof over approximately 7,500m2 of Alumasc’s Hydrotech MM6125 structural waterproofing. The roof also features Alumasc’s Harmer AV Roof Outlets.

Client, HFD Group, was influential in the specification of Hydrotech as they had used ZinCo green roofs on other parts of the Park and were keen to achieve a high performance waterproofing solution for the podium car park.

The green roof provides recreational space for people and a rich habitat for wildlife, as well as facilitating reduced water run-off and lower noise levels. The greater substrate depth of the intensive roof also provides particularly good insulation properties.

ZinCo Intensive green roofs replicate ground-based landscaping for recreational use and are suitable for new build schemes with roof and podium decks. They offer the benefits of a small urban park and support a wide range of plants, trees and shrubs, having a typical substrate depth that ranges from 150-1500mm.

Hydrotech is the first choice for zero falls waterproofing on inverted green roofs and hard landscaped podium structures in new build applications. It is manufactured using 10% post-consumer recycled material, is BBA accredited and has European Technical Approval ETA-05/0152. Hydrotech is designed to last for lifetime of the structure and is available with a choice of warranties.

Alumasc’s Euroroof Mastergold flat roof membrane has provided the optimum waterproofing solution for the urgent roof refurbishment on the sports complex at Wymondham College in Norfolk.

Alumasc – called in by roofing contractors, TC Garrett Ltd – recommended stripping back the roof to the concrete deck and replacing it with a new warm roof incorporating a cut to falls tapered system which would solve the problems of the standing water.

Euroroof Mastergold was chosen due to its suitability for warm roof refurbishment applications. The 20-year warranty was an important factor in the specification, and both roofing contractor and client were impressed with the aesthetics of the charcoal mineral finish.

TC Garrett installed 1200 square metres of Euroroof Mastergold over a thermo-adhesive underlay. The installation involved intricate detailing around new rooflights.

Euroroof Mastergold transforms working with traditional bituminous membranes, speeding up installation time without compromising long-term performance. Euroroof is a fully warranted system that offers high tensile strength and pliability and excellent resistance to puncture and UV degradation. The Mastergold membrane is available with a black mineral finish and can be used with a range of insulations to suit specification and U-value parameters.

A complete package of Waterproofing solutions from Alumasc has been used on the newly extended Ashfield House, the HQ of Ashfield In2Focus, part of the Sales, Marketing and Medical Division of United Drug plc.

The newly extended training and management facility based in Leicestershire, boasts a striking and sustainable design from architects shedkm of Liverpool, which demanded the innovative use of multiple roofing systems including Hydrotech Structural Waterproofing, Derbigum Bituminous Membranes and a ZinCo Extensive Green Roof.

The design comprises three separate roof areas – a car stacking system, a first floor extension to the existing building and a new build rooftop pavilion – each demanding specific roofing solutions. Its success was made possible due to the flexibility of Alumasc systems and the combined skills of the design team, the Alumasc approved installer Monarch Roofing Co and main contractor Sisk.

The Hydrotech hot-melt system was installed on the inverted roof of the first floor extension and provided a continuous monolithic fusion to an existing Hydrotech waterproofing system. Hydrotech is manufactured using 10% post-consumer recycled material and has European Technical Approval ETA-05/0152.

The rooftop pavilion demanded an unusual solution of a 600m2 hybrid zero falls roof, combining both Hydrotech and Derbigum membranes. The use of Hydrotech over the metal deck enabled the roof to be kept lightweight. Warm roof insulation was laid on top of the Hydrotech and finished with a Derbigum high performance cap sheet.

Finally, an extensive ZinCo green roof was installed over Hydrotech to the roof of the steel car stacking units to soften the impact of the units on the view from overlooking residential buildings. ZinCo Green Roofs from Alumasc are available in four broad application categories to suit all needs from extensive sedum roofs to fully landscaped parkland, backed up by alternative waterproofing systems to provide a complete roofing solution from a single source.

The Hydrotech MM6125 Structural Waterproofing system from Alumasc has been used in the construction of the Scottish Centre for Regenerative Medicine (SCRM) – a brand new 9000m2 research facility for the University of Edinburgh.

The £35 million SCRM building was designed by architects Sheppard Robson and built by Miller Construction. Its stunning design includes a number of innovative renewable technologies resulting in a world-leading facility that is both energy efficient and significantly reduces operational costs. The project won the Considerate Constructors Scheme Gold award 2011.

Approximately 1500m² of Hydrotech was installed on the protected roof area by Alumasc’s approved contractor, Grainger Building Services Ltd, using the proven hot melt liquid application method. Hydrotech is a seamless waterproofing membrane that proved ideal for the intricate detailed design elements of the unusual roof. The highly efficient system has also helped the SCRM in becoming the first BREEAM “Excellent” research facility in the UK, achieving a target U-value of 0.15W/m²k.

Throughout the design and installation stages, Alumasc worked closely with Grainger Building Services to successfully meet the varied demands of the project. There were numerous plant decks requiring roof penetrations but it was essential that there could be no risk of water ingress into the building. At this point, Hydrotech came into its own, offering a high performance bituminous rubber blend allowing fast and simple installation around the penetrations and various architectural features including two glass atriums.

Hydrotech unique formulation guarantees lifetime performance and is manufactured using 10% post-consumer recycled material.

Hydrotech is fully warranted, BBA accredited and has European Technical Approval ETA-05/0152.

Hydrotech MM6125 Structural Waterproofing and a ZinCo Green Roof system from Alumasc have been successfully used on the new £44 million campus of Belfast Metropolitan College. The project recently won Environmental project of the Year at the Sustainable Ireland Awards 2011 and has achieved one of the top BREEAM ratings.

The impressive 20,000m² facility, designed by Todd Architects, is set around an inner courtyard and roof garden. 4,000m² of Hydrotech was installed on the concrete podium of the courtyard which is situated above a basement car park.

Landscape architects, Paul Hogarth, specified Hydrotech as part of the green roof package as it can be installed with zero falls, thereby keeping podium height as low as possible. Combined with Hydrogard protection layers and root barriers, Hydrotech offered the ideal waterproofing solution for use beneath Alumasc’s ZinCo Intensive Green Roof.

ZinCo Intensive Green Roof systems enable virtually any type of ‘garden’ landscape to be created and the deep substrate can support a range of plants, trees and shrubs. The College courtyard, where the ZinCo system was installed, offers the benefits of a small urban park, providing a welcome habitat for wildlife as well as additional recreational space for the students.

At Belfast College, Hydrotech impressed main contractor, Patton, who approved its use following a demonstration of its benefits at Alumasc’s headquarters. Roofing Contractors on the scheme were Willart Roofing, who received full training from Alumasc to ensure a successful installation.

Alumasc’s Hydrotech waterproofing and ZinCo green roof systems have played a key role in creating high quality new homes and leisure spaces at Kidbrooke Village in London SE3.

The regeneration project by Berkeley, meets Code 3 for Sustainable Homes and provides for approximately 4,000 private and affordable homes, surrounded by open space, shops, community facilities and an improved transport system.

The specified systems met a strict list of criteria from Berkeley who required a BBA accredited structural waterproofing solution that could be laid to zero falls and would last the lifetime of the scheme. Hydrotech proved ideal for this project as its monolithic nature enabled its use in the phased construction and allowed quick installation.

The first apartments in Phase 1, City point, are now complete, incorporating Hydrotech and ZinCo systems on the podium areas, private balconies, terraces and main roof areas. The roofing specification included Hydrotech inverted waterproofing systems with Hydrogard 20 for the hard landscaped areas and Hydrogard 40 Anti-Root for the soft landscaped areas. The ZinCo intensive and semi-intensive green roofing areas contain growing substrate and appropriate planting.

In total, Tilbury Contracts will install over 12,000m² of Alumasc waterproofing across a total of seven blocks. Tilbury, who were already prequalified to work with Berkeley, put together a highly experienced and trained team of installers who brought Phase 1 of the project to a successful conclusion.

Alumasc’s Derbigum Rapido waterproofing system is a key component in the UK’s largest curved green roof – installed at the new Peacehaven Wastewater Treatment works in East Sussex.

The roof itself covers over 17,000m² – the equivalent of 2.5 football pitches – and required over 16,000m² of Derbigum Rapido.

The sustainable roofing solution roof helped to secure planning permission for the Peacehaven facility, following a decade of delays, by convincing planners of its ability to marry perfectly with the surrounding countryside.

The Derbigum Rapido waterproofing system was a vital element of the green roof and one of the main contributors to the success of the project. The roofing solution was developed by Alumasc and their approved contractor, Prater Ltd who installed over 16,000m² of Derbigum Rapido over the HPS200 coated metal deck single ply structure.

Derbigum waterproofing systems combine durability with the speed and ease of installation of a single layer system. Options are available for completely flame-free, high speed spray installation (in excess of 800m² per day) which is BBA approved and fully warranted.

Hydrotech MM6125 Structural Waterproofing from Alumasc, has been used on the new Sainsbury Laboratory, overcoming numerous challenges presented by the roof’s unusual design.

The award-winning scheme, designed by architects Stanton Williams is an 11,000m² plant science research centre set in the University of Cambridge Botanic Garden. The concrete roof deck features a range of complex details such as photovoltaic panels, roof lights, exposed roof edge details and sunken wells housing mechanical and electrical services.

Alumasc’s Approved Contractor Fenland Flat Roofing installed 6000m² of Hydrotech MM6125 structural waterproofing over the concrete roof deck during a six-month period which took them through the winter of 2010/11. The Hydrotech system was chosen for its high performance bituminous rubber blend which allows fast and simple installation over complex roof details and around penetrations.

The building’s environmental features also tested the skill of the installers. Pebbles were used as ballast around the photovoltaic cells, whilst paving slabs have been used as walkways to provide access to the sunken wells which are designed to hide the M&E services below the roofline.

The project has won several major awards including 2011 World Learning Building of the Year WAF Award; the 2011 Concrete Society Award and was highly commended in the Major Project category of the British Construction Industry Awards. It has also been awarded a BREEAM “excellent” rating for its outstanding environmental performance.

Manufactured using 10% post-consumer recycled material, Hydrotech’s unique formulation guarantees lifetime performance.  Hydrotech is fully warranted, BBA Accredited and has European Technical Approval ETA-05/0152.

 A Derbigum warm roof system from Alumasc has been used in the roof refurbishment of Doddington Community Hospital in Cambridgeshire – a project requiring complex liaison between the contractors who were working around the demands of one of Europe’s largest ever temporary roofs throughout the installation.

The hospital roof had come to the end of its lifecycle and urgently needed replacing.  Following the consideration of a number of options, the client,  NHS Cambridgeshire, decided the entire roof should be replaced.

The versatility of Alumasc’s Derbigum system was a major contributor to the work being finished on schedule, despite the scale of the project and the complicated logistics.

The main contractor, Morgan Sindall, was asked to remove the existing waterproofing and deck and install a new plywood deck. Alumasc approved contractor, Camflat Roofing, installed 1700m² of the Derbigum warm roof system with a mineral surfaced Derbigum cap sheet, carrying a 20 year warranty. The system comprised a 4mm thick dual reinforced Derbigum membrane based on APP modified bitumen with a decorative mineral weathering surface, offering a combination of high performance protection plus speed and convenience of installation.

A huge HAKI temporary roof was used on the project to prevent any possibility of water ingress into the hospital while the roof was being replaced, enabling it to stay open to patients. Even though the temporary roof was one of the largest ever erected in Europe, it still only covered half of the space being re-roofed. All work in progress had to take place under the covered section which was moved on rails to the other end of the roof half way through the job. The work also included detailing around new windows, roof lights, and plant and courtyard areas.

Mick Smith of Camflat Roofing comments: “This job was complex in terms of the logistics and working under the temporary roof. Alumasc’s advice and support during the project was highly valuable and the speed and versatility of Derbigum was also a major factor in successfully completing the job.”

Derbigum warm roof systems combine the proven durability of the Derbigum range, with the speed and ease of installation of a single ply system. Options are available for completely flame-free, high speed spray installation (in excess of 1000m2 per day) which is BBA accredited and fully warranted.

Alumasc’s Derbigum Waterproofing system has played a key role in vital refurbishment work carried out on a prestigious London residential scheme.

Boss House is an upmarket warehouse conversion situated in the Shad Thames District of London. The existing 14-year-old roof urgently needed a complete upgrade, requiring Alumasc to work closely with Lamberts Chartered Surveyors to provide an innovative solution which would avoid the displacement of residents for the duration of the works. Whilst conventional approaches such as temporary roofing would have been prohibitively expensive and highly inconvenient for residents, Alumasc rose to the challenge, providing a competitively priced solution enabling everyone to remain in the building throughout.

The proposal involved attaching a new plywood base to the existing standing seam roof using timber packers fixed into the metal structural purlins. Working with the installer Tower Asphalt Ltd, Alumasc carried out tests on the roof to ascertain the correct fixings and to confirm that it would be possible to carry out work with residents still inside the premises. Tower Asphalt installed 1600m² of 4mm Derbigum Mineral Charcoal, and throughout the project Alumasc liaised closely with the building surveyor, to ensure a smooth operation resulting in work being completed ahead of schedule.

Designed for situations requiring high performance and time efficiency, Derbigum Waterproofing was the ideal solution for Boss House, applying the proven durability of Derbigum with speed and ease of installation. Options are available for completely flame-free, high speed spray installation (in excess of 1000sq.m per day) which is BBA approved and fully warranted. The system is suitable for use on warm roofs with metal, concrete or plywood decks, both for re-roofing or new build applications.

Alumasc has provided a stunning ZinCo green roof for Coworth Park Hotel Spa, the ‘ground breaking’ new eco-luxury spa opened by the Dorchester Collection.

The luxurious spa is situated in Ascot on the borders of Windsor Great Park, buried within the natural contours of the landscape. The building is camouflaged by the ZinCo green roof which is also being used to cultivate thyme, lavender, chamomile and other fragrant herbs for use in natural treatments at the Spa. The pioneering design by architects, Purcell Miller Tritton, has kept the building’s volume and footprint to a minimum whilst intimately relating the spa to its sensitive green belt setting.

Throughout the design and installation, Alumasc liaised closely with Purcell Miller Tritton to find the optimum solution for the unique semi circular design of the Spa’s pitched curved roof.  A total of 700m² of extensive and semi-intensive green roof systems were installed by M&J Flat Roofing over a Derbigum Warm Roof waterproofing system, also from Alumasc.

Green roofs have been increasingly heralded as solutions to many of the challenges that face the UK’s built environment in today’s climate. Recent urban regeneration has led to increased population densities in the UK’s major towns and cities and the associated reduction in soft landscaped areas has created design issues that require sustainable solutions.

Green roofs can counter many of these threats, however, a lack of credible independent reference literature that is specific to the design and installation of green roofs in the UK, has surely restricted the number of installations across the country.

Alumasc has been heavily involved, with a number of fellow contributors, in the development of the GRO Green Roof Code of Best Practise for the UK 2011.

The Green Roof Organisation (GRO) as a body is facilitated by the National Federation of Roofing Contractors (NFRC). The code is a clear concise guide that aims to:

1. Provide specifiers and installers with the requisite understanding of the key issues that affect the design, installation and maintenance of high quality, flourishing green roofs for the long-term;

A ZinCo green roof from Alumasc has been chosen for Westfield London – Europe’s largest urban shopping centre.

The excellent track record of the ZinCo systems and Derbigum Rapido waterproofing from Alumasc, made them the natural choice for this prestigious project, meeting the need for a lightweight and commercially competitive waterproofing solution.

Spanning over 149,000m2, Westfield London is a £1.7 billion development featuring an impressive mix of retail, leisure and restaurant space in West London. Westfield worked with international architects Benoy and The Buchan Group, to design and deliver the innovative curved undulating glass roof above the shopping centre, which earned the project a position as finalist in the LABC National Building Excellence Awards.  The award organisers described the roof as “part of a sustainable design that has paved the way for 21st century retail design in the UK.”

Landscape Contract Designs (LCD) of North Yorkshire installed 15,600m² of extensive and bio-diverse green roof onto the structural metal deck roof. The system features sedum plug plants which will flourish over time, offering notable ecological benefits, providing a natural habitat for plants and wildlife, whilst also helping to reduce air and noise pollution, cutting carbon emissions and assisting with rainwater retention and attenuation.

ZinCo green roofs vary from the extensive and biodiverse types used at Westfield – which require minimal irrigation and maintenance – to intensive roofs, which are suited for areas of public and recreational use and require more tending.

Derbigum Rapido waterproofing, also from Alumasc, was installed by leading building envelope contractor Prater Ltd of Surrey, for the warm roof build up.  This high performance single layer membrane gives exceptional long-term performance and durability, warranted for 25 years. Derbigum is BBA Approved and manufactured under the ISO 14001:2004 Environmental Management Standards. Furthermore, Derbigum is fire rated F.AA to BS476 Pt3 (EN1187 Pt4), the highest available rating, which allows unrestricted use under Building Regulations.

Throughout the project, Alumasc worked closely with the contractors to ensure that products were supplied to suit available crane time-slots, contributing to the successful completion of the project within deadline and budget.

Following their recent success in The BREEAM Awards, Alumasc was celebrating yet again at the NFRC Awards in London on Friday 14th May.

This time, Alumasc’s ZinCo green roofs were the centre of attention, clinching the NFRC Green Roof Award for the exemplary installation at Rockliffe Park Hotel near Darlington in the North East.

Roofclad Systems of Durham installed 1600m² of Alumasc’s ZinCo green roof system on the new golf clubhouse at Rockliffe – located in the preserved countryside of the listed hotel building.  The project presented a challenging design brief to architects Browne Smith Baker of Newcastle, who worked closely with Alumasc’s Technical Team to create the ideal solution for the project. The location for the new clubhouse building was carefully identified to ensure it sat low down in the landscape, with the green roof blending seamlessly into the countryside, making the clubhouse almost invisible from the hotel.

A variety of wild grasses were chosen to harmonise with surrounding plant species and to complement the natural timber profile of the clubhouse facade. Requiring only a shallow growing medium, the green roof offered a much lighter option than turf, which in turn enabled the specification of more cost effective materials for use in the underlying roof structure, which, as a result, would not be required to support as much weight.

The green roof was applied over Alumasc’s Derbigum high performance waterproofing membrane, for exceptional long-term performance and durability.

Finishing close behind Rockliffe was Alumasc’s installation at Regent’s Place in London. The bio-diverse green roof was installed by Tilbury Contracts of Rainham over Alumasc’s Hydrotech MM6125 waterproofing system. The impressive terraced roof, which comprises a number of compartments to form a stunning puzzle pattern, will provide essential habitats to support the survival of some of our rare and scarce plant species, together with a natural habitat for bees, spiders, beetles and birds.

Alumasc’s Managing Director Robert Littlewood comments: “Rockliffe Park is a shining example of how green roofs can be sensitively applied in areas of natural beauty. This award is testament to Alumasc’s Approved Contractor Roofclad and our own Technical Support Team who pulled out the stops to ensure the successful delivery of such a stunning roof.”

For Architects, Developers and Designers considering BREEAM ratings and green credits, the specification of a green roof can contribute to a successful assessment. Simon Poe of Alumasc explains:

The inclusion of a ZinCo green roof system on the roof and terraces at Regents Place in London contributed to its BREEAM rating of ‘Excellent’.

A range of benefits can be attained across BREEAM assessment – from water detention to energy consumption reductions and responsible materials sourcing to life cycle costing – however, the availability of credits in the ‘Land use and ecology’ section, is of most relevance to green roofs.

The exact number of credits available will vary depending on location (e.g. the re-use of land at brownfield or previously-contaminated sites) and application (e.g. schools earn credits by using green roofs in education and forming wildlife partnerships), however the majority of credits required to attain an ‘Excellent’ or ‘Outstanding’ rating can be achieved irrespective of site placement.

There are two principal stages:

1. The replacement of habitat that would otherwise be lost through the construction process – mitigating the impact of the development and protecting ecological features of the site.

2. Creation of new habitats that will enhance the ecological value of the site to provide long-term biodiversity benefit.

Green roof solutions can be devised to score credits in both categories, with the planting strategy critical to habitat creation appropriate to the wildlife habitation objectives. Schemes can be devised to include appropriate mixes of plant species to attract different wildlife.

Alumasc’s ZinCo Green Roof system and Hydrotech MM6125 Waterproofing in use on the internal courtyard at Ormeau Bakery

Following the unfortunate demise of Interbuild last year, the government’s first Chief Construction Advisor, Paul Morrell, has been speaking at a launch meeting for the new show BEST (Built Environment Solutions and Technologies) which premiers at Birmingham NEC in October.

In his speech, Mr Morrell was keen to tackle the subject of retrofit, reminding us that existing structures consume around 40% of the nation’s energy.

Retrofit requires close co-operation between suppliers and specifiers, and at Alumasc we are more than familiar with the processes involved. We work alongside architects and designers on hundreds of projects every year, to encourage the specification of sustainable products and systems to create healthy, efficient buildings that benefit not only the wider environment, but those living and working inside them.

The recent refurbishment of the beautiful Ormeau Bakery in Belfast into high quality apartments, is the perfect example of how new technologies are being used to improve existing structures. Alumasc’s ZinCo green roof and Hydrotech waterproofing systems created a peaceful haven on the podium roof of the late 19^th century building, which will offer recreation access to residents and a rich habitat for local wildlife.

Previously owned by travel giants Tui, Jetset house was used as a training centre and offices for the travel and tourism company. After being sold to a private company in January 2023, the new owners found that this 56,00 sq. ft building, located on a 2-acre site adjacent to Gatwick Airport, was in need of some renovation work.

Brief

reaching the end of its serviceable life. Alumasc were tasked with providing a cost-effective resolution to renovate this substantial 4000m² roof.

As with all our projects the client is assigned to one of our technical teams, who work closely with them to ensure that we provide the best possible outcomes for their criteria.

After lengthy consultation, and a number of conditional site surveys to understand the buildings requirements, we opted to overlay the existing roof with Alumasc Euroroof Torch-On. By using this proven system we were able to transform the existing roof to safeguard the building against future challenges.

Solution

What is Euroroof Torch-On? Used across all building sectors, Euroroof Torch-On systems are perfect for both refurbishment, new-build roofing and waterproofing projects.

Fully adaptable to meet the criteria of Jetset House, the system comprises of a premium torch applied reinforced APP polymer modified bituminous waterproofing membrane, underlays, insulation boards with air and vapour control layers.

How does it work? The membranes are formulated with a superior APP modification and heavy-duty reinforcement. These components result in a long-lasting waterproof roof that has excellent resistance to puncture and UV degradation. Specifically designed and tested to perform in the most severe conditions, Euroroof Torch-On has a service life in excess of 25 years.

Why was Euroroof Torch-On selected for this project? Due to the superior waterproofing properties and durability of the system, combined with an exceptional 25-year wear warranty, Euroroof Torch-On provided the client with the ability to restore the watertightness of the existing structure, improve the roof drainage, and thermal efficiency of the building.

Challenges

Timescales for completion were extremely important to the client. With 4000m² to complete, time was of the essence. Overlaying vast areas of the roof in a short time frame and within a specified budget, meant it was critical for our teams and our registered contractor, Inspire Contract Services Ltd, to work in tandem.

All our contractors are skilled and fully proficient with the installation of our products, which ensures there is no downtime in terms of training and product awareness. This meant works could start immediately. Additionally, our products are designed with ease of installation in mind, reducing all timescales.

Our relationship with contractor Inspire Contract Services, meant that our collaborative approach kept the client up to date with the progress of the project.

Situated in the picturesque area of Surbiton in Surrey, Edward Pinner Court is made up of 21 one bedroom and 11 studio flats. Facilities at the court include a communal room, laundry room, guest room, walkways with landscaped communal gardens maintained by residents.

The association’s Court Manager Service is an important and integral part of their approach to supporting residents. It is designed to offer support and security to those residents who need it. The service is about promoting and encouraging individuals to maintain their independence in their own home.

Brief

During routine maintenance, it was reported that some of the covered walkways linking the different areas of the site were showing signs of general wear and tear. With remedial works attempted throughout. A concern for the elderly residents. The pitched roof had several leaks and was beginning to show signs of structural issues.

Alumasc were approached to find a solution to the problem. Our technical team got to work. James Cramp Regional Technical Manager said “we used the latest technology available to us and undertook a drone survey to understand the full extent of the pitched roofing works”. We analysed the walkways to propose a solution. James adds “in addition, after a full and detailed investigation, we were able to identify that the existing pitched roof was starting to bow under the strain of the traditional heavy roof tiles. Highlighting concerns over health and safety”.

Solution

Due to Alumasc’s comprehensive portfolio, the team were able to present the client with two products working in conjunction with each other to solve the pitched roofs’ problems.

To ensure the walkways were completely waterproof, Caletch QC Balcony, with its thick, fully reinforced
waterproofing layer and a proven track record of more than 20 years, was the obvious solution.

This high-performance system comprises of a range of rapid curing two-component, cold-applied, reinforced PMMA waterproofing. Solvent free, the product is specifically designed for walkways and terraces over occupied premises. BBA Certified and available in a wide range of colours, textures and surface finishes, the team were able to fully tailor the system to meet and exceed the clients’ expectations.

To ease the structural strain on the building, the team presented Alumasc’s Airtile metal roofing system for the main roof area.

Manufactured from high quality Aluzinc Steel, Airtile Slate is extremely lightweight, in fact 7 times lighter than a traditional roof tile, this component also gives the product excellent long-lasting strength and performance, way above that of traditional materials.

100% recyclable, Alumasc Airtile is a high performing, versatile and elegant looking modern-day version of a traditional slate tile. It has all the characteristics you can expect from a traditional slate tile such as authentic finish and riven edges. However, unlike natural slate, Airtile Slate will not crack, break, chip or delaminate.

In summary, the team, together with the client, were able to select two products which solved the issues with the main roof and walkways, making them waterproof, easing the strain on the structure and providing an aesthetically pleasing and consistent look. With a 20-year warranty, the new revamped walkway can be enjoyed by the residents, plus the client can be confident in the structure for many years to come.

Challenges

As with many of our residential projects, the repairs needed to be completed with minimal disruption to the residents within the building and the surrounding area. Working closely with our approved contractor Inspire Contract Services, who undertook the works to a high level of workmanship, we were able to keep the client updated throughout every stage of the project.

Both products dramatically reduced the contractor’s installation times. Extremely quick to cure, Caletch QC can be waterproof within 30 – 40 mins per coat. Not only reducing the installation times, but it is also perfect for use in the unpredictable British weather.

As Airtile is much lighter than traditional roof tiles, installation times were reduced even further. Unlike moving heavy traditional tiles, Airtile is quick, simple, and easy to install, not only ensuring that deadlines are met, but in addition giving the client and contractors the added cost savings over the lifetime of the building.

Board24 are the largest sheet feeder in the UK, the company supply corrugated board to specification across three locations in England and Scotland. Their impressive manufacturing site is situated on the outskirts of Preston in Lancashire, close to the national motorway network.

Certain areas of their vast manufacturing facilities roof were beginning to suffer from age related wear and tear. Our position as the leading UK based roofing supplier and our network of approved installers appealed to the client, which led to the Alumasc team being approached to find a solution.

Brief

Due to visible age-related damage, the risk of water ingress was a major concern for the client. The client wanted to bring the roof areas back to a condition that was both weatherproof and aesthetically renewed, all whilst avoiding disruption to the manufacturing operations within the factory below.

Upon investigation and extensive survey across the huge 24,000m2 site, the Alumasc team identified several issues; extensive peeling of the plastisol coating, large areas of rusting, cut edge corrosion, and several defective rooflights.

Solution

Alumasc were chosen for our metal roof coating system – Caltech METcoat and Caltech QC gutter system. Both products are subject to the highest levels of certification and testing and with a proven track record they offer up to 20 years of protection, with only minimal routine maintenance required.

Caltech METcoat was also used across the site. Developed for the refurbishment of mechanically sound existing pitched roofs and cut edge corrosion, it was perfect for this project. The product comprises a two component, cold-applied, moisture-triggered modified acrylic/urethanebased resin. Applied in liquid form in two or three coats, Caltech METcoat forms a seamless, durable membrane.

Caltech QC comprises of a rapid curing two-component, cold-applied, fully reinforced PMMA waterproofing solution. The wet-on-wet application with embedded polyester fleece, is quick to install and forms a seamless, durable membrane that is rainproof in just 30 minutes. Reducing installation times and keeping disruption to a minimum.

An added benefit to the Caltech range of products is that we can offer an extensive range of colours, offering a true match to any RAL/BS/NCS shade. We were able to present a wide range of colour samples to ensure the aesthetics of the roof were to the client’s approval.

The combination of these products provided the client with a weatherproof and aesthetically pleasing roofing solution, meeting and exceeding their expectations.

Challenges

Due to the sheer size of the project the main challenge was achieving successful adhesion and preparation of the damaged roof surfaces within the specified timescales. This was an important consideration as work needed to be carried out with minimal disruption to their manufacturing operations.

Our longstanding relationship with our contractor BBR Roofing Ltd, meant that our collaborative approach kept the client up to date with all aspects of the installation.

Battersea Power Station is at the heart of central London’s largest visionary new development. The vast 42-acre site is a former industrial brownfield site, now the home to a community of over 250 shops, cafes, restaurants, theatre, hotel, medical centre and nineteen acres of public space, including 450 metres of river frontage and a six-acre park. The £9bn project sees the creation of a vibrant, mixed-use development including a new office district with over 3 million sq. Ft of commercial space, alongside new private and affordable homes.

Brief

The project design was divided between two architect practices, Foster and Partners and Adamson Associates. Both designs played a key part in the regeneration of zones 3A and RS4 of the Battersea site.

The redevelopment included a residential area and high street, known as The Electric Boulevard, situated south of this instantly recognisable landmark.

The goal was to create a neighbourhood that connects into the historic fabric of the city of London, but one that has its own identity. The architect’s vision was to create a humanistic environment that feels good to live and visit.

Collaboration – A Key to Success

After the completion of several successful projects across London’s iconic landmarks, including the Shard and Canary Wharf, Fosters and Partners and Adamson Associates approached the Alumasc team to provide a single source solution for the whole roofing design.

After careful planning and detailing, two complementary products from our portfolio were the perfect solution to delivering the vision. Hydrotech Hot Melt from Alumasc waterproofing system and our Extensive Green Roof would deliver imaginative design complete with durability.

During the extensive planning stage, our collaborative approach with both architectural teams and our registered contractor VolkerLaser, meant the team resolved numerous complex detailing elements across the varied roof zones. Specifically, the soft and hard landscaped podium, which was the central focus to the design.

Lifetime Performance

With zero failures in over 50 years worldwide, Hydrotech Hot Melt from Alumasc offers lifetime performance. Designed for use across all building sectors, primarily in new build construction, this unrivalled system comprises of a one-component, hot applied, fully reinforced, flexible, self-healing hot melt membrane, a range of bituminous protection sheets, insulation boards and ancillary products.

Subject to the highest levels of certification and testing. This fully warranted, BBA and European Technical Approved system is manufactured to last the lifetime of the structure to which it is applied.

Using 40% recycled content, Hydrotech Hot Melt from Alumasc is applied in a liquid state, complete with a special formulation of refined asphalts and synthetic rubbers for a 100% seamless bond. Therefore, avoiding any chance of water tracking. Its monolithic nature ensures no possibility of lap failures and is ideal for the expansive podium required at the Battersea site.

In addition to its impressive performance, the system requires little maintenance. In terms of installation, it is fast and simple to apply, especially over complex roof details like those at Battersea, so time on site is significantly reduced.

Unlike other methods, the system is extremely versatile, and not weather dependant, it can be laid at extreme temperatures (down to -18°C for winter installations).

An Environment that Considers Our Planet

The architects wanted to provide a humanistic environment that evokes a sense of wellbeing by incorporating landscaping across the roof areas.

Modernistic in its approach, our Extensive Green Roof solution is used for lightweight roof decks, inaccessible roofs, or flat and sloping roof spaces.

With stunning visual aesthetics, the introduction of roof landscaping creates a positive impact to the wellbeing of the users, encouraging social interaction as well as playing a key role in providing a positive environmental impact.

Its lightweight construction and shallow substrate, provides versatile range of planting options, comprising of succulents such as sedum, rockery, and alpine plants, which provide ecological benefits by reducing environmental impact with air purification and the reduction of CO₂.

Easy to install, the Blackdown extensive green roof is different to other systems, as they do not require a permanent irrigation system. Another advantage is that general maintenance is kept to a minimum.

Futureproof Design

The inspiring regeneration of Battersea Power Station, showcase’s the world’s best architects and designs. Creating a unique environment for a vibrant community. A combination of our ground-breaking products, careful planning and a 35-year warranty, together we have delivered a design that will be used and enjoyed by residents and visitors for many years to come.

Located within a bustling part of Bromley, London. Darwin House is a residential cul-de-sac comprising a cluster of apartments within a short distance of Anerley and Crystal Palace.

After residents reported major leaks, which resulted in apartments being evacuated, the Alumasc team were instructed to deliver an urgent solution.

Firstly, the client instructed Alumasc to survey the roof and deliver a recommendation to solve the water ingress issue. Secondly, Alumasc were asked to suggest a suitable fixing method for a renewable energy source in the form of solar panels.

Solution

The Alumasc team identified that water was seeping into the 400m² roof through a number of penetrations, over 95 in total. After a full investigation and consultation with the client, it was agreed that stripping the existing roof back to the deck and re-waterproofing using the Alumasc Euroroof Torch-On system would be the best solution.

Subject to the highest levels of certification and testing, the Alumasc Euroroof Torch-On system is fully adaptable to meet the requirements of this project. This proven solution is used across all types of building applications in both refurbishment and new-build.

The system is not only high performing but also extremely durable. It comes with an impressive 25-year guarantee. This assured the client that our range of products are the very best available.

During the client consultation it was also agreed that Alumasc ProSolar; a nonpenetrative photovoltaic mounting system specifically designed for mounting the proposed solar panels would be included within the specification.

The priority was to make the roof watertight again. Euroroof Torch-On with its premium torch applied reinforced APP polymer modified bituminous waterproofing membrane, underlays, insulation boards and air and vapour control layers (AVCL) solved the issues with the existing roof.

Once the structure was watertight, the team were able to install ProSolar to the newly refurbished roof. ProSolar is a non-penetrative mounting system which can be installed without the need to ballast or mechanically fix into the underlying roofing membrane. Without the need for further ballast, the system adds minimal load to the building. The framing structure consists of 92% aluminium resulting in the system being lightweight, strong and resistant to corrosion.

Challenges

The damage to the original roof was extensive. Stripping the roof back to the deck, fixing 95 penetration points, and the installation of the new system all came with different challenges. As with any residential project, time was of the essence as the residents needed to be back in their properties as soon as possible. Working in close partnership with the client and roofing contractor, the Alumasc team delivered this project in 8 weeks.

High Performance and Durability

The combination of Alumasc Euroroof Torch-on with its high performance and increased insulation properties, together with the installation of Alumasc ProSolar, means the residents of Darwin House can enjoy their homes again with the added benefit of lower energy costs for many years to come.

The Galileo Trust have been working alongside property consultants Sanderson Weatherall as part of a Planned Preventative Maintenance programme, to develop the budget requirements for the next 5 years. Alumasc were commissioned to survey five of the ten schools: Galley Hill Primary School, Ings Farm Primary School, Westgarth Primary School, John E Batty Primary School, and The Lakes Primary School. The objective was to identify potential issues with the buildings and propose appropriate solutions.

After a lengthy consultation and survey period, each project came with quite different challenges, however due to the wide range of products available in our portfolio, a solution was found for each of the schools.

Enhanced Environment for Education

Galley Hill Primary School, Ings Farm Primary School, and Westgarth Primary School.

Products: Derbigum Olivine built-up warm roof system, Alumasc Rooflights, ProDrain Outlets, and Alumasc gutters.

In terms of the brief, all three schools were very similar. The trust wanted a watertight roofing solution that was durable and enhanced the environment for the attendees, by increasing access to natural light.

Our technical team surveyed the roofs at Galley Hill Primary School (1,600m²), Ings Farm Primary School (900m²), and Westgarth Primary School (1,275m²), and began to identify areas of failure.

Matty Hyson, Regional Manager for the North & Midlands, Alumasc Roofing, “Our reports advised full removal of the existing waterproofing systems and installation of Alumasc’s environmentally focussed Derbigum Olivine waterproofing solution, alongside complementary rainwater products. In addition to this, Alumasc’s registered contractor installed several new rooflights across all projects to capture as much natural light as possible. The roof at Westgarth Primary School was designed to divert rainwater into ground level water butts for the school to water their gardens and allotments with.”

Derbigum by Alumasc’s most environmentally focussed product is Derbigum Olivine. Olivine (magnesium iron silicate) granules cause a chemical reaction in CO₂ in rainwater which converts it to harmless silicon dioxide (CO₂, i.e., sand), magnesium carbonate (MgCO₃, i.e., inorganic salt) and water. One square metre of Derbigum Olivine will neutralise approx. 1.75kg of CO₂ over its lifetime.

Our technical experts were able to design a solution to meet warranty and quality expectations of the trust. The system provides a waterproofing solution and increases the thermal efficiency of all buildings. With the addition of the rooflights we were able to flood the structures with natural light, creating a bright interior space for the pupils, teachers, and visitors to the school.

Matty adds “We have calculated that the Derbigum Olivine systems will neutralise 2,800kg of CO₂ at Galley Hill Primary School, 1,575kg at Ings Farm Primary School, and 2,231kg at Westgarth Primary School. All projects have a 35-year warranty.”

Another added benefit to using Derbigum by Alumasc is that the system has a life expectancy of up to 50 years and after this time it can be overlaid using Derbigum by Alumasc membranes giving the system a lifespan up to 100 years. The Derbigum Olivine waterproofing solution will help the trust work towards its’ carbon neutral targets. Installing a high-performance waterproofing solution that carries a BBA certificate confirming its’ exceptional service life, means less landfill and no more leaks.”

Challenges

To ensure the trusts maintenance programme ran to specified timescales, we prioritised areas in urgent need of repair to contribute to the trust’s budget planning process. Areas of the roof had to be adapted due to complex detailing and low thresholds.

David Fairley, Partner, Sanderson Weatherall LLP commented, “Over the last 2 years we have worked closely with the Alumasc team to make sure our programme of preventative maintenance runs smoothly for the trust.”

Tim Bethell, Headteacher, Ings Farm Primary School, “The Derbigum Olivine range provides fantastic sustainability benefits for the school, especially with energy crisis at the forefront of our minds, we feel by installing a quality product, this guarantees peace of mind for the academy.”

Once the project ended, in a bid to further the green credentials of the schools, a cherry tree was planted in a project coordinated by Alumasc Roofing, property consultants Sanderson Weatherall and Galileo Multi Academy Trust.

Strength and Aesthetics Combined

John Emmerson Batty Primary School

Products: Airtile and Caltech Alpha

The school required a new roofing solution that was quick and easy to install and gave extra peace of mind with a longer warranty than traditional pitched products.

Working alongside experts in building consultancy Sanderson Weatherall, a pitched and flat refurbishment solution was necessary with the addition of Alumasc rooflights to increase the amount of natural light for the pupils.

David Fairley, Partner, Sanderson Weatherall LLP, “Airtile was the obvious choice for this type of educational refurbishment. Airtile has the advantage of giving a traditional appearance whilst being guaranteed for 40 years against weather penetration. It was a pleasure working onsite with both the Wensley Roofing and Alumasc teams, working on any refurbishment comes with challenges and the regular reporting from Alumasc ensured this was a smooth process.”

Strength and Performance

The aesthetically pleasing Airtile system is a versatile, simple, and elegant modern-day version of a traditional slate tile. 100% recyclable it has all the characteristics of a traditional roof tile with authentic finish and riven edges. However, due to its ground-breaking design, unlike a normal roof tile it will not crack, break, chip or delaminate.

Manufactured from Lightweight Aluzinc Steel (up to seven times lighter than a traditional tile) gives the product excellent and long-lasting strength and performance, far exceeding anything that has gone before it.

Challenges

Critical to the project strategy was ensuring the safe removal of the original asbestos tiles. Wensley Roofing Ltd executed a sound plan to ensure their safe removal and disposal.

James Roy, Quantity Surveyor, Wensley Roofing Ltd, “It’s been over two decades since the use and import of asbestos has been banned in the UK and we see many refurbishment projects like this. Critical to this type of job is designing a safe access point and removing the tiles intact following asbestos removal guidelines, ensuring the safety of the employees and pupils.

Matty Hyson, Regional Manager for the North & Midlands, Alumasc Roofing, “Safe removal of the original roof was a huge component to the success of this project. Alumasc provide a total design service and only work with our registered contractors to ensure the quality and safety of our projects. Airtile and Caltech Alpha worked together as a great combination for the pitched and podium areas. Caltech Alpha was the perfect choice for the school setting because it is an extremely low odour, single component product that requires no mixing and is flame-free.

A Mile of Guttering Waterproofing

The Lakes Primary School

Products: Caltech UV & GRP Trim

Our condition report showed significant areas of failure caused by poor detailing across the school’s internal guttering system which spanned over a mile.

The trust urgently required a quality, non-disruptive waterproofing solution. We were able to design a refurbishment plan using Caltech UV and our range of accessories to minimise disruption to the pupils.

Liam Jackson, Northern Technical Manager, Alumasc Roofing said, “Caltech UV was ideal to give this guttering system an extra lifeline.”

Caltech UV is applied in liquid form in two layers with an embedded reinforcing glass fibre matt to form a seamless, durable, smooth waterproof finish. With 20 years waterproof protection, Caltech UV gave this roof an extended life, meaning no need for a roof strip and therefore less landfill. The product is quick and easy to apply so there was no disruption to the operation of the school.

Challenges

Matty Hyson, Regional Manager for the North & Midlands, Alumasc Roofing, “The application of the Caltech liquid is usually very quick, but we factored in additional time to accommodate the tight details all around this uniquely designed roof.

Sarah Hindmarch, Galileo Trust, “Matty and the team walked us through every step of the process. From the design and specification, a competitive cost breakdown, right through to site support and sign-off.”

Collaboration

Working together with the trust and our approved contractors we have delivered a single source solution across several different projects. All projects come with their own specifications, objectives, and challenges. By utilising our expertise, working with our approved contractors, and applying our groundbreaking product portfolio we can deliver impressive performance, high-tech design, and exceptional customer service to ensure we exceed the expectations of the customer.

Situated eighteen miles north of Birmingham, Lichfield is the home of The Chequers, a housing development managed by Bromford Housing Association. Overlooked by the treasured landmark Lichfield Cathedral, Chequers is set on the edge of a conservation area amongst a city steeped in history, making it a traditional haven amongst the more modern, urban landscape of the surrounding towns. The development at Vernon Street in Ashton-Under- Lyne saw the creation of 23 modern and contemporary apartments. Nicknamed “Cottonopolis” in the 19th century, this modern three storey building was specifically designed to pay homage to the heritage of the local area and recreate the historic Manchester cotton mills from days gone by.

Client Brief

The client sought to futureproof and maximise the lifespan of Sixteen bungalows by converting the existing flat roofs into modern and attractive pitched roofs.

There were two factors of the project that needed careful consideration. The first was location. Due to its location and the surroundings, the aesthetics of the roof needed to be carefully considered. The second was disruption – As residents needed full access to the property whilst work was in progress, it was important to keep any disruption to a minimum.

High Performance and Elegance

After a number of collaborations over several projects, there was no hesitation from Bromford Housing Association when they opted for Alumasc’s Airtile Villa system.

This versatile, simple and elegant modern day version of a traditional slate tile, has all the characteristics you would find from a traditional roof tile with its authentic finish and riven edges. However due to its ground breaking design, unlike a normal roof tile it will not crack, break, chip or delaminate.

Manufactured from Lightweight Aluzinc Steel (up to 7 times lighter than a traditional tile) gives the product excellent and long-lasting strength and performance, far exceeding anything that has gone before it.

Aesthetic Stress Free Installation

Situated on the edge of a conservation area, the new pitched roofs needed to seamlessly integrate with the historical nature of the surroundings.

Bromford and the Alumasc team opted for Airtile Villa – a modern roman style tile, to ensure the character of the building worked with the existing buildings in the vicinity. The team could also achieve a consistent look across the whole site with the ranges extensive choice of accessories and flashings.

Disruption to the residents would be kept to a minimum due to installation times being dramatically reduced compared to traditional installation techniques. The quick and easy installation ensures the job is completed quickly and efficiently, a reason the system is favoured by contractors from all over the U.K.

Long Lasting Strength

A combination of its durability, security and maintenance-free attributes, Airtile slate is made in the U.K and comes complete with BBA certification and 40 years warranty to provide 4 decades of protection against weather penetration.

It’s impressive vandal resistance (0.9mm steel base) and AA classification for Fire resistance is equal to any
traditional roof tiles and slate. The Airtile systems provides added security for the residents within the property in addition to providing the clients with a stress free, cost effective and durable solution to the refurbishment.

To ensure we reduce our footprint on the world the Airtile’s range of roof tiles and systems are 100% recyclable after its life expectancy of 60 years.

Shaun Clewes, Operation Manager from Novus Solutions commented “Alumasc products are innovative and always of the highest quality. Add the teams reliable, professional and supportive service, their collaborative approach to each projects mean we always achieve our goals.

Dan Arrowsmith from Bromford Housing Association “Working with Alumasc is always stress free. We have worked with them on several projects. Their products are world class, and the team are always professional and dependable. It makes us feel very confident in both the company, the products and the service they deliver.

The development at Vernon Street in Ashton-Under-Lyne saw the creation of 23 modern and contemporary apartments. Nicknamed “Cottonopolis” in the 19th century, this modern three storey building was specifically designed to pay homage to the heritage of the local area and recreate the historic Manchester cotton mills from days gone by.

Client Brief

Watson Homes provide sustainable developments, future-proofing social housing schemes for their valued clients. As their preferred supply chain partner, we have worked extensively with Watson homes, producing a detailed specification in-line with their requirements for this project.

Alumasc’s Alkorplan system was a key element in meeting all the requirements needed. A 20-year warranty ensured a technically robust system, with a proven track record of almost 45 years, it is subject to the highest levels of certification and testing. Meeting all current building regulations & guidance.

Due to the local area being well known for its cotton mill industry, the appointed Architects – TADW’s brief was to design a building to “embrace the rich heritage of the area”. The architects impressive roof design, in addition to installing Alumasc’s Alkorplan roof profiles gives the building a pleasing aesthetic finish – replacing the need to use a standing seam roof.

Highest Levels of Certification

Alkorplan is a solution suitable for mechanically fastened applications. Ideal for lightweight fast-track construction, the system is fully adaptable to meet the individual requirements of every project across all building sectors.

The system comprises of a multi-layered thermoplastic 1.5mm PVC-P roofing membrane reinforced with woven polyester, ancillary components, insulation boards & air and vapour control layers. This is a highly effective system with excellent tensile strength and durability. Perfect for residential properties like the Vernon Street development.

Sustainable

The first stage of the installation was to loose lay the vapour control layer, as this would be mechanically fixed into position at a later stage. This mechanically fixed PVC system has the advantage of being easily removed at the end of its life and recycled back into the production to process into new raw material.

Outstanding Performance

The insulation layer was then installed utilising a 200mm Alumasc FF PIR Insulation. This was specified due to the U-Value requirements and its high level of thermal efficiency.

To complete the build-up, the Alkorplan by Alumasc Reinforced Membrane was mechanically fixed in a dark grey colour was installed to compliment the visual design of the project.

Finally, to achieve the desired aesthetic requirements Alkorplan profiles were used to give the appearance of a standing seam roof finish. Creating a stylish and attractive design with substantial cost savings.   

Challenges and Collaboration

This was a challenging yet rewarding project. The roof was designed as an alternative to a traditional pitched roof, using the Alumasc Alkorplan Single-Ply membrane to create a sleek look for a modern build. The roof was finished with Alkorplan standing seam profiles, which complemented the finish perfectly offering an aesthetic alternative to zinc, slate, or tile.

Using our collaborative approach, we worked alongside our approved contractor Enviroply Roofing, who have completed an impeccable job installing the waterproofing with precise placement of the profiles. They overcame the restraints and challenges that come with a multi-pitched roof and the waterproofing was completed in a record time of under 3 weeks.

The result is a high performance, durable, sustainable, and visually appealing building in keeping with the area’s history and heritage, which will be enjoyed by future residents for many years to come.

Client Brief

When Bromford Housing Association approached Alumasc to propose a new roof refurbishment to
Bromford Rise, the brief was to provide a complete redesign of six existing low rise blocks of flats. The
existing bituminous roofs had reached the end of their serviceable life and the task was to create a
modern look in keeping with the surrounding area.

Aesthetic Solution

After conducting a full condition survey of the 6 blocks of flats, the Alumasc team identified that a
bespoke solution was required. Alumasc’s Airtile Slate roofing system was the obvious solution.

The system is a high-performing, versatile and elegant looking modern-day version of a traditional slate
tile.

It has all the characteristics you can expect from a traditional slate tile such as authentic finish, riven
edges and is available in a traditional colour finish.

Unlike natural slate Airtile Slate will not crack, break, chip or delaminate through its ground-breaking
design and cutting-edge manufacturing process.

Airtile’s range of roof tiles and systems are 100% recyclable after their life expectancy of 40 years. They are extremely lightweight being manufactured from high quality Aluzinc Steel, giving the product excellent long-lasting strength and performance, way above that of traditional materials.

Challenges

As this is a residential project, the re-design needed to be completed with minimal disruption to the
residents within the building and the surrounding area.

As Airtile Slate is up to 7 times lighter than traditional roof tiles, installation times are dramatically reduced. Its quick, simple installation gives the client and contractors the added cost savings over the lifetime of a building.

Due to the location of the site, aesthetics were of great importance, a traditional slate look was opted
for and with an extensive range of accessories and flashings, the Alumasc team were able to provide a
consistent look across the whole of the building.

Dan Arrowsmith from Bromford Housing Association “Working with Alumasc is always stress free. We
have worked with them on several projects. Their products are world class and the team are always
professional and reliable. It makes us feel very confident in both the company, the products and the
service they deliver.”

Daniel Grant, Area Technical Manager for the Midlands “A great project to be involved in and a credit to
the whole team delivering another successful flat to pitch project.”

Pen-Y-Dre High School Becomes First Carbon Neutral Refurbishment School in Wales.

Renowned for its high standards of discipline, behaviour and achievements, Pen-Y- Dre High School is
Merthyr Tydfil’s award-winning education centre. The school caters for the educational and development
needs of 800 pupils aged 11-16.

Set in a beautiful green campus, Pen-Y-Dre is famous for its outstanding academic and sporting facilities.
The schools extensive site can accommodate a variety of activities including a full size swimming pool.
Pen-Y-Dre High School is more than an educational building, it is at the heart of the local community, and
is used by many groups outside the traditional school day.

When Pen-Y-Dre High School were looking to refurbish their buildings, they approached Jim Allen award
winning Architectural Service Manager at Blaenau Gwent council, looking for a long-term solution to
update their site.

Client Brief and Design

Building lasting relationships is important to Alumasc, and this project is testament to that. After
collaborating on several successful projects, Jim approached the Alumasc team to survey the roof area
of the site, with a view to providing a durable and green proposition.

After an initial survey of the roof, our team agreed that to meet the clients brief, Alumasc’s Derbigum
Olivine system was the best option. Not only would it meet the need for longevity and durability with its
35 year warranty, the system would substantially reduce CO₂, assisting in making Pen-Y-Dre the first net
carbon High School in Wales.

The First of its Kind

Calculations carried out by the team demonstrated there were several benefits to the Derbigum Olivine
system compared to a traditional felt roof. This environmentally friendly roofing system neutralises CO₂
via an irreversible chemical reaction when it comes into contact with rainwater. Its proven performance
means that 1m² of olivine has the capacity to capture approximately 1.75kg of CO₂.

The teams’ calculations highlighted the U value of the current roof was very poor. Installing the Derbigum
Olivine system would improve the performance to 0.1, increasing the efficiency of the construction,
keeping heat flow through the structure to a minimum, therefore reducing the school’s energy costs.

With these calculations alongside a 35 year warranty, the proposal was instrumental to secure funding
for the new refurbishments to Pen-Y-Dre High School, helping the school deliver their vision to become
carbon neutral.

Technical Information

Alumasc’s innovative roofing system comprise a premium CO₂ neutralising reinforced APP polymer
modified bituminous waterproofing membrane, underlays, insulation boards, with air and vapour control
layers.

Surfaced with a naturally occurring mineral upper layer, this layer initiates a chemical reaction with CO₂
from rainwater, irreversibly neutralising the pollutant on contact.

The Olivine granules cause a chemical reaction in CO₂ in rainwater which converts it to silicon dioxide
(sand) and magnesium carbonate, two products harmless to the environment.

Complete with BBA certification, Derbigum Olivine is a fully warranted system with a life expectancy of up
to 50 years. Although the olivine grains decrease in size with each reaction, the grains are large enough
to span an impressive 30 years before having completely reacted. Not only is the system durable, it is
sustainable, as the membranes used are 100% recyclable.

Long Term Relationships

We pride ourselves on building strong relationships within the industry. Our clients trust us to deliver on
our promises. Having worked with Jim Allen and Morgan Sindall on previous successful projects meant
they knew they were in a safe pair of hands. Construction of the site is being completed whilst the school
is still in operation. Together with the contractors the Alumasc team are supporting the build to ensure
minimum disruption to the school’s activities.

As part of the Alumasc Roofing service we offer transparent quality checking and timely site reporting.
We are always on-site to assist clients before, during and after the installation.

All projects come with their challenges but a roofing supplier’s ability and willingness to tackle them in
collaboration with the client and contractor is of key importance to Alumasc Roofing.
