The newly opened Pets at Home store at Hedge End Retail Park, Southampton, provides a striking feature with its clearly visible barrel vaulted green roof installed by Blackdown. As well as softening the visual impact of the building, the green roof helped to satisfy stipulations by BREEAM enhancing the ecological aspects lost through the construction process.

The impressive 450sqm metre Kalzip, barrel vaulted, standing seam roof was covered with Blackdown Nature Mat – a vegetated mat made up of 6 core and 13 randomly sown sedum species – over a system comprising 50mm settled depth of specially formulated growing medium and a 25mm deep drainage layer.

Because the roof has a maximum pitch of 23 degrees, customised thrust retention battens were installed to the seam clips at intervals across the roof in order to stabilise the system.

Further enhancing the biodiversity within the development, a small 10sqm Blackdown extensive wildflower green roof system was installed on a bike storage facility close to the main building. As the installation was carried out late spring/early summer, Blackdown provided a tailored temporary irrigation system to ensure the establishment of the plants into the system.

Blackdown was in contract with T A Colbourne Projects Ltd and commenting on the collaboration Contracts Manager Tim Bench said: “Blackdown submitted a competitive and compliant bid on which we were happy to place an order. The installation went according to a tight programme with Blackdown working very well with our roof installation team and completing the works in good time enabling us to strike the scaffolding and start on the wall cladding. The temporary irrigation worked very well during what was an extended, very warm and dry period. We would be very pleased to work with Blackdown again”

Pear Tree Infant School required a full flat roof refurbishment following an initial survey that showed that the existing system had come to the end of its serviceable life.

The existing roof finish was stripped back from the metal deck and a new warm roof system installed. The key objectives with this refurbishment was to achieve an average u-value of 0.18 W/m2K thus improving the thermal efficiency of the building.

Alumasc installed a new Caltech UV Cold Applied Liquid Warm Roof System with a tapered insulation scheme to improve the drainage efficiency and prevent future standing/ponding water areas.

The whole installation was carried out using ‘flame free’ products and methods.

To help further improve management of rainwater Roof-Pro ProDrain Outlets were installed – this guaranteed the correct detailing from the roof to the outlets. The existing lightning conductor system was also upgraded to the Roof-Pro Lightning Conductor Clip System.

Finally, a defined Caltech Walkway System was added to provide a more durable surface for traffic and again help to maximise the life of the roof.

Caltech UV has an extended life cycle due to its enhanced UV resistance and is highly adapted to cope well when exposed to sunlight thus avoiding UV Degradation. Caltech UV cures to form a seamless, durable and weather-resistant waterproofing solution.

Tucked away in the picturesque countryside overlooking the historic Jurassic Coast, Ladram Bay is a Devon seaside holiday park.

Ladram Bay Holiday Park needed further storage and maintenance areas within their site therefore a new building was built to facilitate this. In order to be sympathetic to the surrounding countryside it was vital a solution be used that helps blend the building into the landscape. 605m2 of Alumasc’s Semi Intensive Blackdown Green Roof was utilised to achieve this.

The Semi-intensive product utilises a series of wildflowers, hardy succulents, grasses and herb species which was ideal to help mix in with the existing hillsides and landscape. The system had to also be installed on box profile metal sheeting and through close liaison with Blackdown’s technical team and taking into consideration various factors such as weight and future maintenance methods this was achieved.

St Clare’s School in Derby required a roof refurbishment to tackle the existing problems with their current roofing system. The existing roof showed signs of general aging and did not include thermal insulation, also the out-dated fragile rooflights needed upgrading.

St Clare’s needed a flame-free solution that provided minimal disruption to learning hours but also provide a highly durable system that would provide long lasting results and improve the thermal efficiency of the building.

A full 1,400m² warm roof solution was installed to vastly improve the overall U-value of the building along with new Alumasc over-sleeve rooflight units, replacing the old Georgian wire rooflights thus providing the school with a bright internal outlook. U-values were also improved further due to the rooflights multi-skin UPVC design. This roofing system consisted of Alumasc PIR Insulation, Euroroof Self Adhesive Preparation Layer and finally, the Caltech UV Base Coat and Top Coat – providing the ideal solution, tackling the various, complex detailing with this project.

The roof construction is a “Clasp” type construction; popular throughout the 60’s in educational buildings.
The “cranked” construction presents limitations in terms of drainage therefore large areas of ponding water were also located during the initial survey. The Alumasc engineered solution worked with the existing design falls, Alumasc redesigned the gutter details to provide effective drainage to the main field area with specific locations of cut to falls insulation to overcome localised deflection & back fall.

Following installation, the building now achieves a u-value of 0.18 W/m2K as outlined in current Part L2B Building Regulations. Alumasc Hoppers, GX Gutters and Roof-Pro ProDrain products were also installed to improve the flow of water from the roof and work in synergy with the new tapered roof scheme.
The project demonstrates a fully engineered solution; enhancing the inherent design fall to provide a cost effective long term solution.

Caltech UV has an extended life cycle due to its enhanced UV resistance and is highly adapted to cope well when exposed to sunlight thus avoiding UV Degradation. Caltech UV cures to form a seamless, durable and weather-resistant waterproofing solution. For added peace of mind the St Clare’s School was also issued with an Alumasc 20-year warranty.

LHC is a leading provider of free-to-use framework agreements used by local authorities, social landlords and other public sector bodies to procure works, products and services for the construction, refurbishment and maintenance of social housing and public buildings.

During the application process 16 flat roof suppliers expressed an interest in becoming an appointed supplier to the LHC. Following the selection process, 5 suppliers were appointed to the framework with Alumasc scoring highest amongst them. Key areas that the LHC were looking for was quality of product, costs effectiveness, reliability, along with evidence of social responsibility, sustainability, compliance with legislation, quality management, equal opportunities and diversity, health and safety and financial stability. Alumasc also had to back this up with case studies covering all geographical regions.

Why should Public Sector Organisations use the LHC Procurement Framework?

During the public sector product selection process, public sector organisations must utilise systems and products that are fully compliant with current Government specifications. When selecting these products for their project it can be a long and time-consuming process for all involved, it would include deep research into products, whether they meet all the compulsory standards and at the same time ensuring a high-quality product that is within their budget is utilised with the highest standards of aftercare and warranties.

Following meticulous review by the LHC, Alumasc ranked as the top manufacturer for price, quality and value for money for Local Authorities, social landlords and other public sector organisations throughout England and Scotland (SPA) and top supplier for price and value for money for Wales (WPA). The use of the framework also provides the client with a highly competitive rate from the supplier. The use of this framework provides key decision makers within the Local Authority during the specification process with a quick way of sourcing a cost-effective, fully compliant flat roof supplier. Only the use of LHC approved suppliers will give public sector bodies this luxury. Annual project rebates are also available to those public sector bodies that register with the LHC as a member.

Richard Wilby, LHC Technical Manager said:

“Congratulations to Alumasc on being the top-ranked flat roofing supplier for England, Wales and Scotland through a rigorous framework tender exercise. The weighting of LHC’s Flat Roofing Framework (FR2) encompassed a tough ‘Quality’ criteria, including an emphasis on ‘Social Standing’ and ‘Price’, to which Alumasc completed a very competitive and well thought out tender return. The LHC FR2 framework will run from May 2017, through to April 2021 and LHC is left in no doubt that the framework is serviced by the best companies for supply and install throughout the country”.

River Clyde Homes is the first organisation to procure through SPA’s new Flat Roofing framework. The Housing Association awarded the £1,000,000 project to manufacturers Alumasc Roofing Systems and Graham Roofing (Scotland) who will install the new Caltech Waterproofing System.

River Clyde Homes, based in Greenock, West Scotland, provide affordable rented accommodation to around 6,000 tenants. The project will see removal of the original roofing of three high-rise blocks in the Broomhill area of the town. The original felt roof covering on the blocks will be replaced with a newly insulated Caltech waterproofing system.

The OJEU compliant Flat Roofing framework met River Clyde Homes’ requirements and provided a clear and transparent procurement process. It also offered a cost-effective and long-term solution to roof deterioration, potential damage to external wall systems and water ingress on the flat roof areas.

River Clyde Home’s Senior Programme Officer, Brian Hughes, described SPA and the tender process as ‘robust, reliable and diligent in the assessment of quality and cost with positive outcomes in terms of the collaborative approach and support of SPA.’

The flat roofing project is due to complete in December 2017. The new roof covering will provide much-needed insulation and will increase the ‘U-value’ of the three high-rise blocks. This will assist in the reduction of heat loss, therefore, decreasing fuel bills for the residents in the future.

The Safe2Torch campaign will directly affect at least 50% of all the flat roofs installed in the UK.

Kevin Taylor, Head of Technical Services at NFRC says: “Roof fires caused by gas torches, no matter how minor, pose a serious threat to life, property, the image of the industry and possibly even the long-term future of torch-on as an accepted method of covering a roof. NFRC believe that by working together, fires of this nature can be prevented, which is why we have launched our Safe2Torch campaign.”

The Safe2Torch campaign is designed to support specification writers to comply with the Construction Design and Management Regulations 2015.

The CDM regulations state that ‘The person who selects products for use in construction is a designer and must take account of health and safety issues arising from their use. If a product is purpose-built, the person who prepares the specification is a designer and so are manufacturers, if they develop a detailed design.

The guidance includes an illustrated document which is free to download and includes an updated safe specification checklist. This checklist will form the basis of an electronic surveying app, which the NFRC will be launching. Users will be able to upload photos and notes via a smartphone or tablet, with a webcast setting out the main points of Safe2Torch for those conducting the surveys as well as tips on how to use the surveying app.

The Safe2Torch guidance also covers the reduction of fire risks in general, including drying out decks and hot works permits etc.

JR Roofing were kindly invited by Moto In The Community Trust to take part in their annual Charity Clay Pigeon Shooting at E.J Churchill in High Wycombe.

Greg Bourne from Alumasc Roofing Systems joined JR Roofing having worked closely with them recently on a Moto project to refurbish a footbridge over the M6. It was a really enjoyable day which comprised of 11 stands, with different types of clay pigeon shoots on each stand.

There was also a chance to use pistols with blanks, a rifle they called the blunder bus and also some axe throwing. There were food stands throughout the day in different areas of the range and drinks and doughnuts.

After the shoot they held a meal and auctions to raise money for Help for Heroes as this is Moto’s main charity partner.
