The UK government’s strategy set out last year to achieve net zero in the built environment, has meant that working to achieve this has become a top priority for contractors & specifiers as well as suppliers.
The importance of early engagement with supply chains during building design has never been so important, especially when developing ethical and sustainable specifications to incorporate cradle-to-cradle (C2C) strategy. But how can architects and specifiers apply this thinking when it comes to flat roofing design?
Product Selection
Working closely with an experienced and accredited manufacturer from the outset and selecting the most suitable materials for the roofing project, is paramount. As an expert in manufacturing waterproofing, insulation and soundproofing solutions, Soprema has been making great strides in sustainability for some time.
Bituminous Membranes
Soprema’s range of bituminous flat roofing products fit the bill when it comes to cradle-to-cradle specification. Our DuO HT 4 AGR/F C180 FC – a bituminous membrane solution – is comprised of a double bitumen coating with fire-retardant additives and a composite polyester reinforcement. Products like this are often specified in roofing as an upper layer within a single or multi-layer waterproofing system, where fire retardant properties are required.
Quality Specification
When it comes to responsible sourcing, using products made from recycled materials is also important. Soprema’s SOPRA XPS recyclable insulation is produced from recycled polystyrene with climate-friendly CO2 technology.
In addition, Soprema also offers natural insulation materials – such as Pavatex – made from wood residues from sawmills, which reduces environmental impact and offers a more sustainable insulation alternative.
During design stages, architects should also consider the product circularity; is it reusable and can it be part of a closed chain?
A Greener Outlook
When specifying products, aside from the appropriate C2C accreditations, BBA approvals and adherence to mandatory testing, it’s also advisable for contractors and specifiers to look outside the box and consider the manufacturer as a whole when adhering to circular economy principles.
