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.

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.
