SWA passes the hot test

Always seeking to ensure steel windows meet or exceed the latest building regulations, the Steel Window Association has undertaken extensive thermal performance simulations of the W30 and W40 window ranges. The results prove without doubt that both window types are fully compliant and achieve 2013 Part L requirements.    

W30 steel windows from Steel Window Association members are the slimmest steel options currently on the market and for domestic applications achieve a BFRC WERS C-rating and, where necessary, can achieve a WERS B-rating. The C-rated window incorporates an 18mm double glazed unit comprising a 4mm soft coat low-e glass and 4mm clear float, sandwiching a 10mm krypton gas-filled cavity with a warm edge spacer bar.

The W40 system for windows and doors, available from Steel Window Association members, offers full compliance with Part L of the 2013 Building Regulations so may be employed for new build and refurbishment in residential units, offices, hotels, hospitals and schools. The range includes doorsets and screens and the profile accommodates 28mm thick IG units. This means triple glazing becomes an option, although warm edge spacer bars, gas filling and other enhancements enable Part L to be complied with in new build, for most applications, when specifying double glazed units.

From a lifecycle perspective, all the steel elements of both the W30 and W40 windows are ultimately BFRC W30 WERS B Licencecompletely recyclable. The credentials of steel windows are recognised by the BRE ‘Green Guide’, which gives them an above average B rating.

Nick Burton, SWA’s Technical Consultant, comments: “The Steel Window Association constantly works towards improving the window systems that are available and the report resulting from the thermal performance simulation of the W30 and W40 window ranges sends out a very positive message. We’re delighted that our potential customers have the option of using steel windows in a wide range of applications and enjoying all the aesthetic benefits that they offer.”
