W40 Windows

W40 hot rolled steel profiles have been specifically designed by the SWA and for the SWA members.

They provide even greater flexibility in terms of maximum manufacturing sizes and can accommodate thicker double or triple glazed units.

Doors manufactured using W40 profiles with triple glazing can achieve a 1.5 W/m2K thermal rating.

Some customers specify this system due to it being able to accommodate up to 32 mm glazing and so it can be specified with acoustic glass which may be desirable when the property is backing onto areas with persistent noise issues.

Multi locking windows and doors are available in this system
