Macmillan Academy Adds Another Green Initiative.

Set up as a City Technology College in 1989, Macmillan Academy strive to improve the economic prospects and social opportunities for the 1600 pupils who attend. Registered as an Eco-school over 15 years ago, Macmillan Academy are committed to reducing carbon emissions and waste. Their aim to develop an awareness of the issues around sustainability is a key value at the very heart of the academy’s mission statement.

Located in inner city Middlesborough, the Academy is one of two sites monitoring air quality across the area. Working in conjunction with Middlesbrough council, automatic monitors measure pollutants associated with road traffic activities and the site was selected due to its proximity to the intersection of the A66 and A19.

As the government looks to tighten its commitment to reaching net zero carbon by 2050 – and local authorities declare climate emergencies, Macmillan Academy approached Faithful & Gould consultants to help secure funding via the CIF on behalf of Endeavour Academies Trust. The brief included procurement and project management of the build to help deliver a sustainable solution to future proof Macmillan Academy’s buildings and support their green initiatives.

Client Brief

As part of the application for funding, Faithful & Gould needed to evidence the condition need for the roofs’ replacement and demonstrate value for money, in line with The Department of Education’s minimum standard of quality and warranty requirements.

The Alumasc technical team conducted several site visits to assess the full extent of the project. A full survey was carried out and core samples were presented to the client. The investigation resulted in a comprehensive report that recommended a full refurbishment using Alumasc’s Derbigum Olivine roofing system. The report concluded using this system would meet and exceed the requirements of the clients brief.

A Sustainable Solution

Sustainability and value were at the heart of this project. By recommending the Derbigum Olivine system, first and foremost CO₂ emissions associated with the academy’s location would be dramatically reduced. Secondly due to its underlays and insulation, energy efficiency would be increased reducing energy costs, and finally Derbigum Olivine would exceed The Department of Education’s minimum quality and warranty standards. The proposal would provide maximum long term performance and a low maintenance solution going forward.

Alumasc’s innovative roofing system comprises of a CO₂ neutralising APP/TPO plastomer modified, composite reinforced bituminous waterproofing membrane, underlays, insulation boards, with air and vapour control layers.

The system is surfaced with a naturally occurring mineral upper layer that initiates a chemical reaction with CO₂ from rainwater, irreversibly neutralising the pollutant on contact.

This chemical reaction converts to silicon dioxide (sand) and magnesium carbonate, two elements harmless to the environment. When rainwater rolls off the roof and reaches the drains, it’s totally carbon free. The system demonstrates innovation in construction industry science at its finest!

Its proven performance means that 1m² of olivine has the capacity to capture approximately 1.75kg of CO₂. In addition to Derbigum Olivine’s CO₂ neutralising capabilities the Alumasc underlays and insulation boards deliver impressive energy savings. It was estimated that the new Alumasc roofing system would deliver a 26% reduction of annual gas consumption for the Academy.

Derbigum Olivine complete with its BBA certification, is a fully warranted system that requires minimal routine maintenance with a life expectancy of up to 50 years. The olivine grains decrease in size with each reaction, however the grains are large enough to last 30 years before having completely reacted. In addition, membranes on this innovative roofing system are 100% recyclable.

Challenges

Matty Hyson Alumasc Regional Manager North and Midlands commented “Updating this huge 3,500m² site without disruption was a challenge. Mid programme the scope of works were altered to mitigate time and costs. Our team supported the changes, attending the site at short notice. By conducting a significant amount of core analysis, we were able to confirm the changes were appropriate and ensure they were delivered on time.”

Collaboration for a Green Future

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.

Sarah Foster Faithful & Gould Senior Surveyor – “Alumasc’s service is exemplary. They support at all stages of the project from survey/conception through to post completion/warranty works. They are always looking to improve their service and never try ‘the hard sell’ – their service and product speaks for itself, no need to convince. Their team is always available to assist no matter how short the notice, with some clearly highly experienced team members in the industry.”

Chris Bott Everlast Director “This is another key education project completed with Alumasc. Again Alumasc and our delivery team have worked together to ensure the client has received a quality installation to maintain their building assets for long term sustainable future.”

Manufactured in accordance with ISO 9001:2015 and ISO 14001:2015, Alumasc offers a comprehensive range of options. Installed exclusively by Registered Contractors and underpinned by Alumasc’s extensive project support service and warranties.

Winner of the NFRC 2022 Scottish Roofing Awards – Reinforced Bituminous Membranes.

The best of roofing projects in Scotland were celebrated at the NFRC Scottish Roofing Awards on 28th
October 2022 at the Grand Central Hotel in Glasgow. The judges rewarded standout projects for quality
workmanship, innovation, strong supply chain management and impressive responses to challenges on
the project.

The Diamond Offshore Drilling project came first place in the Reinforced Bituminous Membranes
category, for its impressive example of technical innovation to find a solution for the client.

Project

Alumasc Roofing was selected to carry out a full roof refurbishment at the Scottish headquarters of
contract drilling services provider, Diamond Offshore Drilling. The site comprises offices contained within a two-storey building topped by a metal roof which had become severely corroded. This compromised the roof’s insulation, with other issues such as excessive leakage, major condensation and poor termination at drainage points resulting in disruption to day-to-day operations for office staff. As a matter of urgency, the client required a roofing solution that irradicated the risk of water ingress and condensation whilst improving the building’s overall thermal performance. Thanks to the company’s decades of experience in supplying roofs that meet a range of complex requirements, Alumasc Roofing had the ideal solution.

Innovative Design

The 1,200m² roof’s complete redesign was necessitated by the existing system’s severe corrosion and
failure. The client, considered numerous replacement options, including over-sheeting the building with
a metal roof and providing a painted finish. In conclusion, Alumasc Roofing devised a hybrid option that
was fairly unique in its methodology, and comprised a plywood frame overlaid with Alumasc’s Euroroof
Mono bituminous system. This built-off-frame solution was seen as the most credible design in terms of
robustness, the thermal outcomes it facilitated and the time and cost-effective speed with which it was
delivered.

Installation Benefits

When it came to the installation, the existing roof was overlaid with a new structural timber deck. This
was mechanically-fixed to steels below the existing metal roof, allowing the installation of the new,
bituminous roofing system from Alumasc Roofing. The benefit of this option meant that the air and vapour control layer (AVCL) could be installed directly to the timber deck; thus providing immediate waterproof protection to the structure.

Alumasc’s GTF PIR Insulation was PU adhered to the AVCL in a single layer built-up roofing system. The
Alumasc Euroroof Mono cap sheet was also bonded in PU adhesive and hot air gun-welded at all
termination points. Detailing to the roof was achieved using Alumasc’s Euroroof Self-Adhesive Underlay
and Euroroof Self-Adhesive Cap Sheet.

Sustainable Option

The roofing system was installed totally flame free, mitigating the risk of fire and resulting in a low-energy
application. In addition, the roofing solution has a proven life expectancy in excess of 25 years and after
this period, it can be overlaid with another waterproofing layer to give the roof an additional lease of life,
this eliminates the need to send the existing system to landfill.

Assurance

Alumasc Roofing’s design and technical expertise was integral to the successful roof refurbishment works
at Diamond Offshore Drilling. The system itself came with a 25-year system warranty, adding to the client’s peace of mind that their new, hybrid solution will keep their flagship office building warm and dry for many years to come.

Alumasc Replaces 13-Year-Old EPDM Roof Short of its Declared Lifespan

Since 2004 upon what was once Belfast City’s Gasworks, overlooking the River Lagan, James House has
been home to office accommodation for various government agencies. Originally complete in the early
aughts on a historic brown field site during the population and housing boom, a mere two decades later
the building is part of a major initiative to upgrade and modernise for the next technological office age.

Bespoke Roof Condition Report

Technical re-design service included the most suitable waterproofing – incorporating efficient drainage and thermal performance. Full strip and replacement of the existing EPDM roof.

Derbigum sustainable flat warm roof system. Full capabilities including carbon cleaning technology, and 40 years+ lifecycle.

Sustainable warm roof performance includes:

• BROOF (t4)
• BBA system certification
• 35-Year system warranty
• Olivine waterproofing resulting in neutralising 3,500kg of CO₂

Client Brief and Design

Alumasc Roofing’s Site Technician team explained, “The core sampling showed 4 inches of saturated insulation, rucking, and insufficient upstand heights. The membrane was found to have had an inadequate fixing pattern to the loose laid EPDM membrane. The termination to the existing roof outlets was also a major contributing factor to the failure of the total roof system. Along with wear on the rainwater outlets, cracking, blistering, and distortion, all contributing to the significant failure of the original waterproofing.”

Working closely with the Kennedy Fitzgerald Architects, Alumasc Roofing technical experts were able to design a solution to meet the key longevity, warranty, and quality expectations of the client.

“Given the immediacy of the roof failure our report advised a full roof strip of all existing roof covering back to the concrete structural deck. This allowed full access to the concrete deck for structural repair work to the defects caused by the original waterproofing system. This allowed the new sustainable warm flat roofing system to be installed efficiently and incorporating a full high performing AVCL to the structural deck. This system was completed with a full cut to falls insulation design improving the drainage strategy and thermal performance. The warm roof system was completed utilising 2-layer BUR waterproofing, consisting of Hi-Ten Universal underlay and environmentally focussed Derbigum Olivine cap sheet.”

Challenges

• Re-design of current drainage positions (both internal and external)
• Thermal upgrade to meet current building standards
• Tying in with existing building envelope
• Working in close proximity of live railway network
• Meeting current fire regulations

Heslington East Campus Student Residences: Sustainable and Efficient Expansion

Goals

Architects Sheppard Robson alongside Graham Construction sought to futureproof accommodation by incorporating multi-use buildings, including catering outlets and social hubs. Key to the brief was using the latest in safety, energy efficiency, longevity, and warranty credentials. Graham Construction’s use of modular external sandwich panels, prefabricated steel bathroom pods, and pre-assembled services distribution racks used Modern Methods of Construction with off-site construction techniques.

Challenges

The major challenge was to specify a roofing system that could keep up with the pace of the build, given the typical building was constructed from start to finish in circa 14 weeks.

The roof deck comprised of precast concrete slabs which facilitated the works programme for speed of construction and consistency in build quality.

Alumasc’s challenge was to find not only a waterproofing solution that was able to keep up with such speed of construction but also to meet a truly sustainable life cycle equalling the lifetime of the building.

A key consideration in the design was the roofing materials’ thermal properties. To meet the u-value target of 0.15, Alumasc’s XPS Plus insulation was specified, providing a single layer of 175mm, which reduced the height of the overall build-up when compared traditional XPS.

Solution

Hydrotech 6125 Waterproofing System / Derbigum Hybrid Upstands

For over half a century Hydrotech Monolithic Membrane has been successfully used by architects and specifiers, ensuring some of the world’s most prestigious buildings and structures are kept watertight. With no product failures in over 50 years and guaranteed waterproofing integrity for the lifetime of the structure, Hydrotech offers a total life cycle solution for the building.

Hydrotech was specified on the main roof areas for this project as it easily meets individual requirements of the buildings. In addition, the system is designed to last the lifetime of the building or structure to which it is applied, giving long-term waterproofing integrity and no future replacement costs.

Applied in a hot liquid state to the deck, and including a polyester reinforcement, the bond of Hydrotech MM6125 is 100% absolute. There is no risk of water tracking below the membrane and because it is monolithic, no possibility of lap failure.

Derbigum Waterproofing

Derbigum sustainable roof system was selected for the upstand areas. This hybrid solution was developed to improve the thermal efficiency in all areas to mitigate against cold-bridging with minimal insulant thickness. Derbigum bituminous membranes are high-performance waterproofing systems offering extended warranties and the highest levels of project support. The upstand zones benefited from Derbigum Mineral which is a mineral surfaced composite reinforced membrane.

Rooftop Management Strategy

In addition to the waterproofing solution the buildings benefit from the full Alumasc rooftop management service. This included the design and supply of safety systems, accessories, and over 20 AOV smoke hatches meeting all British and European standards.

Specific safe zones were designed by Alumasc Roof-Pro and positioned around all roofs for safe access. Purpose made clips for installing lightning conductor tape without roof penetration were also provided. All rooftop accessories are part of the Alumasc Roofing specification and therefore can be found back-to-back within the Alumasc 35-year system warranty.

Scotland’s Largest Single Office Building with Rooftop Running Track and 360 Panorama.

A Sustainable and Futureproof Roof, Harnessing the Power of the Outdoors

Bothwell Street in Glasgow is now home to an exceptionally progressive office space – making way for
a new chapter in the rich history of the area. If there are any doubts about what Grade A office space
really means, then think touchless entry, bike storerooms, lux changing facilities, an 8,000 sq. ft roof
terrace, a 150-metre rooftop running track, 4 activity zones/terrace spaces and panoramic views.
The project complements the sustainable regeneration programme along the Clyde Waterfront also,
home to the new financial Northern European hub, firmly cementing the business district at the heart of
modern Glasgow

Goals

The architects at Sheppard Robson have made sure sustainability and lifecycle credentials remain
central to the design specification. Occupants’ wellbeing has been carefully considered with a stunning
panoramic rooftop and 150m running track and general outdoor employee wellness facilities.

A roofing solution was required to support the lifecycle of the building along with an excellent
product reputation for this distinguished office space. Given the quality, longevity and environmental
considerations required from the roofing design, the insulation properties and warranty performance
were extremely important from the outset.

Challenges

Our Technical department assisted the architectural and construction teams to resolve numerous
complex design elements across the varied roof zones including running track, ballast walkways, green
zones, and pedestal zones, to determine the best roofing solution.

Installation of the Davit Arm System for a building of this scale was especially important so personnel can
be safely suspended whilst working at height. This presented us with a unique challenge in providing a
workable solution that aligned with the sequence of works, whilst facilitating future routine inspection of
its base plates, and maintaining waterproof integrity without compression.

Careful planning and detailing were required around roof penetrations to minimise aesthetical impact,
and roof equipment was safely installed above the roof assembly.

Solution

The construction comprises a composite concrete slab receiving our Hot Melt Hydrotech Waterproofing System. Offering a true lifecycle – Hydrotech high performance waterproofing, through its’ unique characteristics and installation process, now forms part of the building fabric. The result offers complete watertightness for the lifetime of the building.

The building is also insulated to a high u-value target offering exceptional thermal performance and achieving a high kPa rating. This was essential to receive loadings from all components including
overlying finishes, roof equipment and the end use for the building occupants.

Key fire performance standards were achieved throughout including the lift overrun and lower roof terrace areas where the preferred solution was switched to our Derbigum sustainable warm roof system to maintain project performance targets.

Lifecycle Management

Designed with BREEAM credentials and an EPC rating coming in at below 10 the careful focus on lifecycle
considerations and the choice of materials throughout the building envelope is exemplary.

Hydrotech hot melt is a high-performance solution containing 30% recycled content and zero product
failures in over 50 years, offering lifetime peace of mind, designed for the service life of the roof.

A 5-minute hop from Cardiff Queen Street and you’ll find the first blue roof in Wales. Upon what was formerly 1960’s office accommodation the Cromwell House site has been transformed into an 8 storey, 120-bedroom easyHotel with a rooftop stormwater management system.

Our Design Process

Our clients at Carter Lauren Construction were interested in learning about the benefits of a blue roof to meet planning conditions.

”Working in a compact city centre environment where ground attenuation was not possible, it made sense to install a blue roof. The Alumasc team demonstrated how their BluRoof System attenuates stormwater via controlled discharge over a 24-hour period at roof level.” Kevin Jenkins, Surveying Director, Carter Lauren Construction.

Client Brief and Design

Working closely with the appointed consulting engineer and architect, our team of technical experts designed a solution for stormwater attenuation to comply with planning and meet all other project objectives.

Alumasc’s Matt Davies, Area Technical Manager – Mid, West & South Wales commented, “Given the urban location, the Alumasc BluRoof system was the perfect fit in providing a fully warranted single-source waterproofing and sustainable drainage solution.”

The Alumasc technical team provided a full specification service and specialist drainage design using key data from the project brief. By incorporating our BBA Accredited Derbigum APP polymer modified bituminous waterproofing system the longevity of the total solution is assured with a proven track record since 1967.

Other key components comprise of a BluRoof geotextile filter fabric, BluRoof interlocking void former, flow control outlets, and overflow system.

Environmentally Focussed Solution

Extreme weather events are now the new normal, says the World Meteorological Organisation. Our rainfall patterns are becoming increasingly unpredictable, and we must plan accordingly to adapt the built environment to help alleviate flood risk.

Partnership

Working with the contractor to construct the first blue roof in Wales. Kevin Jenkins, Surveying Director, Carter Lauren Construction, “Matt and the Alumasc team were available throughout the design and installation process. We knew that installing the BluRoof by Alumasc was the right decision for the future of the easyHotel and the benefit to reduce pressure off the drains.”

Built in 1936 Haven Green Court is a prominent fixture in the local roofscape. This locally listed residential 4-storey mansion block of flats is steeped in rich history at the heart of the west London Borough of Ealing.

Client Brief and Design

The site itself dates back to 1890 and due to the age of the property and several areas of failure, the contractor Tower Flat Roofing was tasked by the client Haven Court Green Ltd with refurbishment, whilst preserving the most distinguishing feature, a mansard roof covered with glazed green pantiles.

The priority was to provide a full roof overlay using sustainable, durable materials to extend the current roof’s life, stop the failing areas and prevent a full re-roof scenario from an environmental waste and cost reduction point of view.

Paramount in the clients’ brief was the longevity of the refurbishment system. The decision to select Alumasc Roofing’s Derbigum Insulated Overlay to the existing waterproofing system was made due to the reputation and the minimum 40-year durability provided in the BBA statement.

The Solution

Alumasc Roofing supplied a built-up Derbigum system along with Alumasc BGT Polyisocyanurate (PIR) insulation, a CFC and HCFC free rigid urethane thermal insulation board. This built-up system comprised of a torch applied membrane.

In addition, Roofpro accessories including freestanding guardrail system pipe supports, and Caltech QC terminations were used, incorporating tapered insulated gutters.

Derbigum High Performance Roofing Systems are reinforced APP polymer modified bituminous waterproofing membranes, underlays, insulation boards and air and vapour control layers (AVCL).

Sensitive Refurbishment

The priority was to avoid roof removal and replacement and undergo a timely, sympathetic roof refurbishment with an overlay, causing minimal disruption to residents and reduce the environmental impact of replacing the roof entirely in terms of sustainability and waste reduction.

Complexity

As the roof was beginning to fail due to its’ age the concern was whether it could be overlaid. Time was critical and if left longer the project scope would have been removal and replacement. The avoidance of landfill and prolonging the performance of the building were key to the success of the preservation.

A significant challenge was to protect the glazed green mansard pantiles and ridge interfaces to preserve the history and aesthetics of the building. The project centred on protecting the character of the historical building, by delicately working around the original features and details.

The project began in June 2020 and the building was at full occupancy during challenges of both the refurbishment and the pandemic, which presented additional health and safety considerations. Minimal interaction with the residents was ensured by erecting scaffold with single traffic flow at the rear of the building.

Partnership

The Commercial Director of Tower Flat Roofing, Barry Yardley and James Bentley of Lamberts Surveyors nurtured a close relationship with the premises manager Chris Lubbock, Haven Court Ltd. A consistent onsite presence giving the project regular focus and both liaising closely with Chris ensured any unforeseen problems were kept to a minimum.

The Alumasc Roofing local site technician also supported this project extensively, with regular reports which demonstrated the weekly progress through photos and inspection.

Chris Lubbock, Haven Green Court Ltd, “Being made aware of Barry and the team and Tower Flat Roofing’s track record on similar large mansion blocks in London, we already had confidence that they had the skillset and experience in managing such a complex project, whilst ensuring they met our key requirements and the priority unique expectations of protecting and preserving the delicate features of this historical building.

We also wanted to use Alumasc Roofing’s Derbigum product on this job, as we were aware of the fantastic products and their longevity, coupled with the fact that Alumasc give such a robust warranty due to the high durability properties of the solution proposed.”

James Bentley, Lamberts Chartered Surveyors, “Barry’s commitment and the consistent on-site presence between us all demonstrated that the Tower team really care about the project running on time and on budget, and that approach even saved four whole weeks on completion date! The job ran seamlessly, and we are proud to have contributed to successful completion during the hazard that was COVID-19 and delivering to such high standards.’

To meet the specific client requirements, the design team at Alumasc Roofing, Tower Flat Roofing and Lamberts Chartered Surevyors worked together to create a strategy so that the original features of the building could be retained with confidence.”

About

Haven Green Court’s iconic imposing stature made it a popular filming location for Ealing Studios films including, ‘The 39 Steps’ 1959, ‘The Wrong Arm of the Law’ 1962, and ‘Doctor in Distress’ 1963. A great team effort to be part of maintaining a piece of London’s history and avoiding re-roof to reduce waste.
