Ebury SquareAn 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.

University of Greenwich Blackdown RoofA 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.

University of Greenwich Blackdown RoofThe 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.”

University of Greenwich Blackdown RoofThe 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.

Derbigum Roofing “The Jewel in the Crown”

Posted by david.luukas

 

Derbigum Roofing 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.

EcoCampus, Hamilton International Park - Alumasc Hydrotech & Zinco Green RoofAlumasc’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.

Wymondham CollegeAlumasc’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.

Derbigum is key at Peacehaven

Posted by david.luukas

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.

For more information on Derbigum, click here

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.

Alumasc Facades will be showcasing their range of thermally efficient External Wall Insulation solutions in readiness for the forthcoming Green Deal initiative.

Come and see us on Stand S2010.

 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.

Firestone RubberGard® EPDM waterproofing from Alumasc has been used on the new eco-friendly visitor centre at the world-famous Batsford Arboretum.

The Arboretum, near Moreton in the Marsh, Gloucestershire, is home to the largest private collection of trees and plants in the country. The new visitor centre is part of a £2m project coordinated by main contractor BEAM Construction (Cheltenham) Ltd and funded by the Batsford Foundation. The scheme incorporates a number of environmental features including a ground source heat pump, sheep’s wool insulation and a low-profile roof which will reduce volume and minimise energy consumption

Following careful consideration of the surrounding landscape, John Falconer Architects presented a unique and challenging ‘wave’ roof design to emulate the rolling Cotswold Hills, thus minimising the visual impact of the Centre. Firestone RubberGard® EPDM waterproofing was chosen for the project due to its eco-credentials, ability to form clean edge detail and its life expectancy of up to 50 years.

RubberGard® EPDM is a fully cured single ply membrane composed of EPDM polymer and carbon black, offering unrivalled resistance to ozone and UV radiation. Membrane characteristics remain stable over time thus providing a sustainable roofing solution which perfectly suited the Arboretum project. RubberGard® does not contain any plasticizers or flame retardants and as no toxic substances are released this allows collection and use of run-off rainwater.

RubberGard® EPDM is available in panel sizes up to 15m in width and 61m in length, giving the benefit of fewer field seams and a shorter installation time. It is inherently durable, remaining flexible at temperatures down to -45ºC, is competitively priced and delivers low life-cycle costs due to minimal maintenance requirements.

Alumasc worked closely alongside Firestone Authorised Contractor Cardiff Single Ply Roofing for the duration of the project, providing full technical support on all of the roof details.

Derbigum to the Rescue at Boss House

Posted by david.luukas

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;

2. Highlight the implications of different green roof specifications;

3. Standardise and clarify the terminology used to describe green roof issues and components through the publication of definitions for key terms;

4. Enable specifiers to comparatively assess the different manufacturers’ systems through the provision of guidance as to the function and relevant performance characteristics of each component within the build-up;

5. Guarantee a minimum quality standard for systems that comply with the requirements of the Code;

6. Promote the benefits of green roofs and highlight how different green roof build-ups can be tailored to prioritise specific objectives;

7. Highlight important health and safety issues that must be observed at the early design stages of a project;

8. Encourage green roof installers to undergo specialist, structured training courses to gain the expertise that will underpin greater numbers of quality green roof installations;

9. Provide for the long-term success of green roof installations by encouraging entry into maintenance contracts with the installing contractor;

10. Provide a foundation upon which further iterative developments can, in time, be based; leading to green roof guidelines that are as comprehensive as any available, including the publication of standard procedures for the characterisation of components and of required performance levels, so as to underpin the continuous improvement of green roofs in the UK.

johnferneleyPRFirestone UltraPly TPO™ from Alumasc has been used on a new 800-place secondary school building in Melton Mowbray which has achieved a BREEAM rating of ‘Very Good’ and an EPC ‘B’ rating.

The John Ferneley College is undergoing a two-phase re-development by the Willmott Dixon Group, the first phase of which boasts an impressive new college building and landscape designed by architects and sustainability consultancy White Design Associates Ltd. The project showcases a number of sustainable features and construction techniques which have contributed to its impressive green credentials.

The Firestone UltraPly TPO waterproofing system was specified for the college roof due to its ease of installation, heat reflective and energy efficient properties. Its light coloured surface reflects sunlight before it can be absorbed and converted into heat energy, thus improving the energy efficiency of the building. The membrane can also be easily recycled, making it the perfect solution for environmentally sensitive applications.

Approved Contractor BriggsAmasco, installed 2500m2 of UltraPly TPO Fully Adhered System in Light Grey. The hot-air welded seaming process results in fast, economical installation, which can be carried out all year-round in a variety of weather conditions. The application of UltraPly TPO was part of an ‘enviro-ready’ roof design, enabling the addition of sustainable features such as green roofing and photovoltaics at a later date.

Firestone UltraPly TPO combines aesthetics and outstanding seam strength with strong resistance to ultraviolet radiation and weathering. It contains no plasticizers and no halogen flame retardants resulting in outstanding resistance to UV radiation and ozone. The membrane also exhibits strong resistance to algae and fungi growth and common rooftop chemicals.

PR_1Alumasc ZinCo has provided a series of stunning bio-diverse Green Roofs for central London’s new mixed-use development Regent’s Place. Believed to be the first of their kind in the UK, the roofs are designed to create a high value bio-diverse environment through the provision of a broad range of wildlife habitats.

Regent’s Place is a multi-storey development comprising office space and residential dwellings. The roof was designed by Arup who worked closely with British Land, and project architects Terry Farrell and Partners, to implement a corporate Bio-Diversity Action Plan. The brief was to design bio-diverse roofs covering two terraces and a third roof area. With all the spaces occupying prominent locations, the appearance of the roof planting at different times of the year was an important consideration.

Tilbury Contracts of Rainham installed a total of 2600m2 of Alumasc’s ZinCo green roofing over three buildings. Combining all the available types of green roof build-up, the roofs provide instant aesthetic appeal, while enhancing the local ecological resource. The waterproofing membrane and inverted roof insulation was first covered with a reservoir board followed by a ‘puzzle’ pattern of polyester powder coated compartments. Each compartment was then filled with a particular growing medium i.e. pebbles, limestone chippings, pellite, crushed brick and pine bark strippings, semi-intensive soils, sand and hardwood split logs.  The substrates were installed at different depths and planted with a wide range of plants, including mosses and sedums, wildflowers and grasses, small shrubs and aquatic species within the pre-formed ponded areas.

The project provides the essential habitats needed for rare and scarce plant species, as well as invertebrates such as bees, spiders and beetles and a foraging habitat for one of London’s bio-diversity action targets, the Black Redstart. ZinCo green roofs also offer other notable benefits, assisting with rainwater management, helping to reduce air and noise pollution and cutting carbon emissions.

Sarah Cary, Sustainable Developments Executive at British Land, comments, “British Land is committed to encouraging biodiversity and we have developed green roofs at many of our properties. By working in partnership with Alumasc, we have used the latest innovation and technology to develop habitats which encourage wildlife and support native plant species in urban areas.”

A further 11,800m2 of Alumasc’s Hydrotech MM6125 waterproofing was installed to the ground floor and 15 separate areas, including plant rooms and terraces. Hydrotech is the first choice for zero falls waterproofing on inverted green roofs and hard landscaped podium structures in new build applications.  BBA accredited, it is designed to last for lifetime of the structure and available with a 20 year warranty. Hydrotech is manufactured and supplied under ISO9001:2000 & 14001:2004 Quality and Environmental Management Standards.

westfield_prA 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.

pr_picAn extensive ZinCo green roof from Alumasc is a key design feature on a new award-winning mental health facility near St Albans.

The Oak and Beech units at Harperbury were built within a green belt environment, to a design by Dransfield Owens De Silva Architects. The project has since gone on to win a prestigious Building Better Healthcare Award for Best Mental Health Design.

Planted courtyards and green roof areas were incorporated into the design after service-users and staff identified the therapeutic qualities of green outside space. The sloping green roofs were installed by Approved Alumasc Installer Letchworth Roofing, over a layout of complex levels around the courtyards, ensuring the green sedum aspects were visible from ground level.

With their relatively shallow substrate, ZinCo extensive green roofs are ideal for lightweight decks, inaccessible roofs and flat or sloping roof areas. Their versatile and economic design provides a ‘back to nature’ solution offering strong ecological benefits, perfectly suited to the site’s green-belt location. The roofs at Harperbury support self-sustaining sedum plants that require minimal irrigation and are highly wind, frost and drought resistant.

The roofs were installed over Derbigum single layer waterproofing, also supplied by Alumasc. Derbigum is a tried and tested roofing solution suitable for warm roofs with metal, concrete or plywood decks and inverted roofs with concrete deck.

Alumasc sponsor GRO at Greenbuild Expo 2010

Posted by david.luukas

GRO LogoAlumasc are proud sponsors of the Green Roof Organisation (GRO) stand at this year’s Greenbuild Expo from 26-27 May 2010 at Manchester Central.

GRO was formed as an independent body to represent the industry trade associations and the key players in the green roof market, developing guidance for specification, design, manufacturing, installation and maintenance of green roofs.

Its 3 principal objectives are:

  1. To promote the green roof concept
  2. To provide suitable guidelines to manufacturers and installers
  3. To recognise and promote correctly trained roofing companies

Strand PRpicGreenbuild Expo is an exhibition and conference promoting sustainability in the construction industry and Alumasc will be present on the GRO stand for the duration of the show to provide help and advice on all aspects of green roof specification, installation and maintenance.

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.

rockliffe_nfrcRoofclad 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.

regents_place2Finishing 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’.

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 19th century building, which will offer recreation access to residents and a rich habitat for local wildlife.

Alumasc Blue Roof for Redcliff Quarter in Bristol

Posted by Ashlea Williamson

Redcliff Quarter is a bustling new neighbourhood for Bristol, bringing together restaurants, a 4-star hotel, offices and apartments. The 600,000 sq ft development has an urban artisan design reflecting the area’s industrial heritage.

The architecture includes wider pavements, roof top and courtyard gardens, balconies and terraces, targeting BREEAM excellent ratings for the commercial buildings. Alumasc’s BluRoof monolithic membrane 6125 qualifies for an additional 0.125-0.25 BREEAM points, making it the ideal waterproofing system for Redcliff Quarter.

blue roof bristol

BluRoof System:

blue roof bristolBlue roofs are designed to alleviate flood risk by reducing and controlling the peak rate of discharge in compliance with design requirements. This facilitates the detention of stormwater up to a prescribed maximum hydraulic head for subsequent controlled discharge over an elongated period.

The blue roof at Redcliff Quarter is used in a buried application for the podium and green roof spaces. By combining the green roof and blue roof systems, the retention of stormwater in the green roof layers complements the detention of stormwater by the blue roof to provide valuable additional drainage capacity.

The Alumasc BluRoof system benefits from the combined expertise associated with Alumasc Roofing Systems and Harmer Engineered Drainage Systems; allowing a truly single source blue roof solution that is integral to a system of this nature. The BluRoof is fully BBA approved and Alumasc provides a service package that provides the client, specifier and end user with complete confidence in the integrity of the waterproofing and drainage solution.

Green Roof System:

Blackdown installed a combination of extensive sedum green roofs and/or paving over Alumasc’s BluRoof waterproofing system, as well as more traditional intensive green roofs, including bespoke planters and seating on the terrace roof areas. The papyrus coloured powder coated planters, with integral hard wood seating, have all been specifically designed by a local SW fabricator to make the roof spaces a recreational asset to those living in the apartments – planted with mixed herbaceous, shrubs and trees the hard and soft landscaping provides the perfect place to relax.

Gelliswick Church in Wales VC School required a roofing system that would provide inhabitants with a reliable solution for the longevity of the building. Alumasc’s fully warranted Mastergold warm roof system was the ideal solution for the project.

school with warm roof

The voluntary controlled primary school was formed following the decision to discontinue two nearby schools, the new school entity was established on 1st September 2017, with the school operating across the three existing sites. It was of the school’s interest to quickly relocate the students and staff from the other two sites to the new build, which opened in January 2018. This Mastergold system offers a quick and easy installation process without compromising the long-term performance of the waterproofing, it also requires minimal maintenance – another reason why the system was the ideal solution!

 

school with warm roof

2,200m² of the Mastergold system was installed by the Alumasc Registered Contractor, Nautilus. The warm roof system included only 5 elements. Alumasc’s Self-Adhesive Primer was used to condition the metal deck, then, to encapsulate the deck from flames the Euroroof Dual Bond Vapour Control Layer was installed. The Dual Bond VCL has a self-adhesive backing to the underside and a thermofusible upper surface which enabled the PIR BGT insulation to be bonded directly to the membrane. To complete the warm roof system Mastergold Underlay was bonded to the BGT insulation which is torch receivable and the Mastergold Black Cap Sheet was then torched to the underlay providing a highly durable and effective solution.

The waterproofing is backed with an Alumasc 25-year system warranty, providing added peace of mind. The Euroroof Mastergold membrane offers high tensile strength and pliability and excellent resistance to puncture and UV degradation. The Euroroof Mastergold membrane is fully BBA approved and is tested for wind uplift and fire performance to meet with the current British Standards.

Material Store will provide 189 buy to rent apartments with residents’ parking and a communal garden.

The Old Vinyl Factory is a compelling project and was one of the largest regeneration projects in West London, home to a new community of more than 630 apartments with commercial and leisure facilities including restaurants, shops, cafes and bars.

green-roof

The four ‘warehouse’ blocks of Material Store rise above a central podium area and surround an oasis of private patios and a large communal garden space. Each of the four main blocks were landscaped using a variety of Blackdown Green Roof products and finishes with the aim of providing an extended living space or ‘outdoor rooms’ for the inhabitants of the building.

green-roof

The aim was to provide added recreational space and a greener environment for adults and children living there.

These areas include large green spaces that have been landscaped to provide a natural setting. These areas are made up of small trees and shrubs to give a natural effect and attract local wildlife. Blackdown’s intensive green roof system was ideal for these key requirements. An intensive roof – akin to a traditional ‘roof garden’ – often replicates the features and benefits of a domestic garden or city park; providing space for recreation and amenity. Applications can range from outdoor roof space at restaurants and office blocks to ground-level landscaping above subterranean car parks at shopping centres or residential developments.

Rob Beswick at B D Landscape Architects says:

“I visited site on Tuesday and was really impressed with the completed Material Store development – the podium landscape and roof terraces are well installed and great to see a project where the quality of the soft landscape hasn’t been compromised – so well done to your team!”

Green Roof Recreation and Play Area

Also incorporated was an area aimed at providing children with green space for them to play, in an otherwise highly built up area, thus improving their health and wellbeing for the future. Blackdown provided bespoke intensive planters containing a variety of wildflowers, sedums and shrubs. Paved areas, benches, decking and artificial lawns were also installed.

The inclusion of a podium play area was of interest as the play and recreational equipment was included within the initial design. This included large pebble seats, bears, large 3D resin play models and active play equipment.

These elements required a wide range of fixing and mounting solutions that were not initially designed for a podium deck. To provide adequate health and safety, gates and fencing were also installed, all of which, used specialist fixing methods to not compromise the waterproof integrity of the waterproofing membrane below.

Constructed by CCG, The Ellerslie Road Development is a new build, high rise residential project located in the Yoker district of Glasgow on the northern bank of the River Clyde and is the tallest CLT building in Scotland.

Alumasc Facade VBriQ Aricco system high rise building in GlasgowCross laminated timber or CLT is a structural, prefabricated panel used to form environmentally sustainable, walls, roofs and floors across a wide range of structures. The gluing of both longitudinal and transverse layers, which reduces the movement of the wood, means that CLT more than meets the standards required by modern building materials. CLT allows for quicker construction adding further sustainability compared with traditional construction methods.

Alumasc Exterior Building Products sets itself apart within the marketplace by providing a single source solution for the full envelope of any building project by combining the products and expertise of Alumasc’s various systems. These key benefits include unparalleled, single point technical assistance, extensive warranties and ongoing post-project support in relation to the full exterior of the project. Mast Architects specified Alumasc’s Roofing Systems, Façade (Walling) Systems, Rooflights and Harmer Drainage Outlets.

Flat Roof System:

Derbigum Olivine warm roof system in glasgowWith sustainability being a key part in the construction of Ellerslie Road, a Derbigum Olivine warm roof system was installed to provide a highly effective insulation for the roof areas. Derbigum Olivine cap sheet is coated with natural granules that neutralise CO2 found in rainwater upon contact. Olivine is also a fully BBA Certified solution which includes a durability statement which includes a service life of more than 40 years.

Derbigum logo

Alumasc provided full technical support throughout, particularly when providing the cut to falls BGT Polyisocyanurate insulation system to help provide added drainage efficiency.

The combination of these elements helps make the building more energy efficient by achieving a 0.13 U-value and improve the atmosphere on the outside. Alumasc Rooflights were also installed around the roof to allow the desired daylight to enter the building. 510m2 was installed by Alumasc Registered Contractors Hugh L.S. McConnell Ltd.

Walling/Facades:

Alumasc VBriQ Aricco GlasgowDue to Yoker’s Cross-Laminated Timber (CLT) pre-fabricated construction, Alumasc Façade Systems’ Lightweight VBriQ Aricco was installed as it is specifically designed for use on timber frame constructions, providing a ventilated façade to protect the structure from the effects of moisture/water ingress. Again, the Alumasc technical team provided comprehensive support from start to finish. The ventilated cavity ensures that the timber substrate is kept dry in accordance with TRADA recommendations by allowing the building to breathe and prevents interstitial condensation.

VBriQ Aricco logo
The system provides aesthetically pleasing, UV resistant synthetic brick slips that can be replicated to almost any brick type – Sanctuary Scotland opted for Mid Brown, Traditional Brick Style (see pic). Furthermore, in keeping with CLT construction, VBriQ Aricco is quick to install (often upwards of 10 m2/day). With the inhabitants’ safety being of paramount importance this system provided the perfect solution having achieved an A2 fire-rating (A2-s1,d0). VBriQ Aricco is also backed up with BBA Certificate 15/5211. The system is also highly weather resistant in relation to wind driven rain, this was also key due to Ellerslie Road’s location alongside the River Clyde. 1100m2 was installed in total.

Benefits of Alumasc’s single source building envelope solution

Exploiting the combined expertise of Alumasc Roofing and Facade Systems allows a truly single source building envelope that we believe is integral to a system of this nature. Alumasc’s nationwide network of registered contractors combined with our own site monitoring team(s) ensures compliance with the warranty and codes of practice are observed through to completion.

The holistic approach to the design allowed for interfacing to be performed pre-contract allowing for installation on time, on budget and without compromise in terms of quality.

Split responsibility may result in the use of various trades and contractors, which in turn may lead to installation errors, damage to materials or negative warranty implications. The Alumasc Single Point Warranty limits this.

Alumasc’s single point warranties assure CCG and Sanctuary Scotland that if they require any further support in relation to this project in future it can be swiftly and efficiently provided from one single point of contact. This also includes details designed by Alumasc or any workmanship queries.

The Brunswick Shopping Centre in London required a refurbishment to bring it into the modern era. This included providing the waterproofing solutions to all the main piazzas, walkways and podiums. With over 50 years zero product failures Hydrotech Structural Waterproofing was installed, this included a build up of XPS Inverted Insulation and the Hydrotech Hot Melt itself. Beneath these piazzas is a cinema and car park, therefore waterproofing integrity was vital. Hydrotech Hot Melt Waterproofing is fully BBA approved.

Alumasc’s BluRoof – frequently asked questions

Posted by Ashlea Williamson

Q1. Can we purchase an Alumasc Blue Roof outlet without the waterproofing?

Blue Roof build upAlumasc has developed the BluRoof system that benefits from the combined expertise associated with Harmer Engineered Drainage Systems and Alumasc Roofing Systems. The result is that Alumasc is ideally positioned to offer a single-source solution, fully warranted waterproofing and sustainable drainage solution that is integral to a system of this kind.

We do not offer drainage attenuation design as a standalone package to be used in combination with any non-Alumasc product.

Q2. What are the typical flow rates that can be achieved using an Alumasc BluRoof?

BluRoof is an engineered drainage approach that addresses the individual project requirements. Blue Roofs are calculated to a whole rainfall series not just a single value, as intensity will change with time and therefore providing a default flow rate without analysis is not practical.

Q3. What information is required to provide a Blue Roof calculation?

The following key project parameters should be assessed to ensure that they are taken into consideration within our calculation.

1. The total size of the applicable areas in m², and if any other areas are draining onto them, the size of them also. Roof plan
    preferably in .dwg format would be required if the size of area was not advised.

2. The plan size of the applicable void former area in m², if less than the total plan area.

3. Are there any height constraints that would restrict the depth of void former that can be accommodated within the
    proposed assembly.

4. Are there any project targets identified for the Blue Roof to achieve, for example:
    – A particular peak run off rate in litres per second (l/s).
    – The detention volume of water (m³) to be attenuated per roof area.
    – A particular % reduction in the site peak run-off rate

Q1. What is the fire rating of Alumasc Extruded Polystyrene?

Fire performance is declared Euroclass E under EN 13501-1. A flame retardant additive is also present that makes it capable to resist, for a short period of time, a small flame attack without substantial flame spread.

When ballasted with either 20/40mm grade aggregate (minimum depth of 50 mm) or fully-supported cast stone or mineral slabs of at least 40mm thickness, the roof may be considered to be of designation AA (low vulnerability in Scotland) and so is unrestricted by the national Building Regulations.

Q2. Are there any non-combustible insulations compatible with Alumasc roofing systems?

Two insulations rated separately as ‘non-combustible’ (i.e. class A1 to EN13501) are Foamglas and Rockwool Multi-Fix Dual Density Mineral Wool. Both products are compatible and available as a system within the Alumasc product offer as part of a warm roof assembly.

Q1. Can Hydrotech 6125 Monolithic Membrane be installed to Plywood?

There are no issues with the installation onto a Plywood substrate. As part of the preparation works it will be necessary to tape substrate joints with approx. 100 to 150mm wide strip of Flex Flash F laid centrally, bedded into a thin skim coat of Hydrotech Monolithic Membrane 6125 prior to main works.

Q2. What are the differences between the Hydrogard Protection Sheets used as part of the Hydrotech 6125 system?

Hydrogard 20 Protection Sheet is categorised as the standard grade product for use within an inverted roof assembly. It is a polyester reinforced, oxidised bituminous protection sheet, with a sanded finish to the upper side. Not suitable for application where exposed to Ultraviolet (UV) light.
Hydrogard 30 Protection Sheet is a more robust product suitable for use where the imposed loads are expected to be much higher. It is a glass/polyester reinforced SBS modified bitumen membrane, with a black mineral surfaced upper side.
Hydrogard 40 Protection Sheet is a heavy duty product incorporating a root resistant additive making it suitable for use within a green roof assembly. It is a polyester reinforced, APP modified bitumen, root resistant membrane, with a charcoal mineral upper surface.
Hydrogard 50 Protection Sheet is an extra heavy duty product principally engineered to meet the specific requirements and stresses for civil engineering works. It is a dual glass/polyester reinforced APP modified bitumen membrane, with a smooth black finished upper surface.

Q3. Can EPDM overlap Hydrotech 6125 Monolithic Membrane?

hot melt waterproofing systemThe use of EPDM flashings typically as part of a façade or cladding assembly which are required to overlap the Hydrotech 6125 waterproofing is common and a widely acceptable detail. The critical factor is ensuring that the EPDM product and its method of application will not have any adverse effect on a bituminous membrane i.e. by using a non-solvent based bitumen compatible adhesive. In the first instance the supplier of the EPDM should be asked to confirm in writing that the product will not have any adverse effect on the primary waterproofing system, which can then be further evaluated for compatibility by Alumasc technical services following receipt of appropriate product data sheets etc.

The effectiveness and bond strength of the product to the Hydrotech 6125 waterproofing is the responsibility of the adhesive product supplier to establish (by test if necessary) and confirm. As with any third party supplied products, it must be noted that should the product have any adverse effect on the Alumasc waterproofing at any time, any costs for any remedial work found to be necessary would not be covered by the Alumasc warranty.

Q1. Can Alumasc provide written confirmation that concrete tolerance and deflections noted within structural engineers report are suitable?

The acceptability of the level of deflection of a concrete deck is a matter for the client, the main contractor and the structural engineer to determine in accordance with the prevailing standards, regulations and codes of practice as identified in the National Structural Concrete Specification for Building Construction. Standard construction tolerances for concrete surfaces are generally acknowledged as having no deviation of more than 9mm over a 3m length, or any abrupt irregularities of more than 3mm. Deviations in excess of this definition are the responsibility of the client or their appointed agent to rectify.

Where deemed unsatisfactory, correction of any slab outside tolerance resulting in a negative fall would be recommended to ensure that all design parameters are sustained throughout the lifecycle of the roof, and should ideally be brought within standard construction tolerance and noted.

Q2. Can Alumasc provide a solution for the localised correction of concrete tolerance and/or deflection?

Alumasc Monoscreed is a fast curing PMMA based compound screed specifically engineered for this purpose. The cold applied compound can be mixed at roof level and applied from 3mm to 50mm in order to bring levels back to acceptable tolerance. The system is unaffected by ambient temperatures, is rainproof within 15 minutes of being applied and will fully cure in circa 45 minutes, thus offering significant programme benefits when compared with more traditional screeds.

With recent events in the UK highlighting the requirement for compliance with up to date and relevant fire test standards, Alumasc Roofing Systems have conducted further fire tests on the market leading Derbigum high performance bituminous membrane warm roof system.

 

Fire rating certificate

Derbigum Mineral and Derbigum Black full warm roof built up systems including primer, vapour barrier, adhesive, insulation, underlay and Derbigum cap sheets recently underwent rigorous testing to CEN/TS 1187:2012 – Test methods for external fire exposure to roofs (part 4) and ultimately achieved the highest grade, BROOF(t4) in fire safety available in the UK, which allows unrestricted use under the Building Regulations (see Approved Document B Section 14: Roof Coverings – clause 14.5 table 16).

ENV1187 Test 4 is a test method used to determine the performance of flat roofs to external fire exposure, the two-stage test method replicating exposure to burning brands, wind and supplementary radiant heat.

Exova Warringtonfire Gent conducted the tests in their brand-new facility in Belgium, confirming not only the applicability of original Derbigum fire rating tests but also confirming the compliance of the current warm roof build-up using the latest BBA Certificated Derbigum system, to reflect real in-use performance.

Alumasc understands the importance of this issue, having previously achieved top fire ratings to the previous standard (BS 476 pt3) on these products, and we, therefore, took the initiative to ascertain the fire rating of our latest systems in anticipation of tighter regulations governing the fire resistance of construction products.

Fire tested roofing membraneThis certification underlines Alumasc’s reputation for quality, performance and reliability, our aim being to provide our customers with unrivalled peace of mind when utilising our products and take all the steps necessary to facilitate this, including this certification which is designed to protect property and life from fire.

Specifying certificated products, systems and services in support of fire safety and security of any facility demonstrates due diligence and shows consideration for those that invest, develop, design, manage and use Alumasc’s Roofing Systems.

 

Legislation and the requirement for compliance to enter new markets has never been tougher and Alumasc will continue to develop and test their products to ensure we provide the highest levels of safety to not only our customers but the inhabitants and users of the buildings our products help to protect.
