W40 steel screens offering stylish performance

The doorsets and screens now available from members of the Steel Window Association offer specifiers the ultimate blend of style, security and sustainable performance.

As the most modern version of the traditional W20 steel window, the W40 system achieves continuity of style with similar attributes in terms of slenderness and light transmission, while the greater profile depth creates room for 28mm thick IG units. This means triple glazing becomes an option, although warm edge spacer bars, gas filling and other enhancements enable Part L of the Building Regulations to be complied with in new build, for most applications, when specifying double glazed units.

In addition to improved thermal performance, weather-tightness is significantly enhanced and fittings can be less obtrusive: with variable geometry hinges, friction pivots and multi-point locking cremone bolts concealed within the profiles. W40 system installations can also be supplied to Secured by Design standard and will be looked upon very favourably by insurers.

Darren Lloyd of SWA member, Govette Windows comments: "W40 fenestration solutions offer specifiers a lot of attractive options, including energy performance matching the latest requirements of the Building Regulations, and high security.

"The feeling of openness achievable is also very good thanks to the strength of steel: with doors of up to 2.5 metres in height being available, and the maximum width of a fixed screen being three metres. Members are supplying W40 doors and screens for top end residential as well as offices, hotels, hospitals and schools."

W40 windows offer good sustainability credentials. The source of steel billet, rod and strip, from which steel window profiles are formed, is basic steel smelted from 100% recycled scrap.

When steel windows are finally replaced, the original windows can be systematically dismantled and the frames, fittings and glass recycled. The credentials of steel windows are recognized by the Building Research Establishment's ‘Green Guide', which gives them an above average B rating.

Steel Window Association

The Steel Window Association (SWA) represents the great majority of UK steel window manufacturers, ranging in size from the smallest of craft-based companies through to large, multi-site companies. There is not a steel window project of any description, anywhere in the UK, that one of the SWA members cannot handle.
