SARNAFIL ROOFING SYSTEM CONTRIBUTES
TO ACHIEVING LOWEST CARBON LIVING IN UK
Setting new standards in low-carbon living in the UK, the Greenhouse development in the Beeston area of the city involves the part-refurbishment and part-new-build of a redundant art-deco hostel to create 172 high-specification apartments plus office space.
This award-winning project pioneers sustainable technologies, and hence its roof features solar thermal panels to heat occupant’s water, wind turbines to generate electricity to power communal lights and lifts, and a waste and rainwater collection system that sees water filtered and used to flush toilets and supply washing machines.
In total 2,500sq m of Sarnafil’s G410-12EL membrane in Light Grey were fitted to the roof. The build up also benefits from increased levels of insulation to significantly improve the Greenhouse’s thermal performance. Dubbed ‘super insulation’ by the developers, this combination of Kingspan’s TR27 and TT47 insulation build ups helped the roof achieve an average U Value of 0.10. This, together with the external wall insulation comprising 130mm of Kingspan Kooltherm K5 External Wall Board, is expected to result in an approximate annual saving of £600 on resident’s energy bills.
