W30 Windows

W30 hot rolled steel profiles are an evolution of the W20 profiles and were specifically designed so that windows could be manufactured in ‘multilight’ designs without the need for coupling bars that would thicken the profiles. This system was also designed so that it conformed with modern thermal requirements to Part L building regulations for domestic windows and so achieves ‘BFRC’ energy ratings.

This system is particularly suited when replacing existing single glazed steel windows which may no longer warrant keeping.

They are double glazed, galvanised and powder coated and so minimum maintenance is required.

The windows can be specified with a variety of hinge, handle and peg stay choices. Where customers require additional security these windows can be specified with concealed multi locking systems.

Shaped frames are also possible and so gables, raked heads and arches are not a problem for our members. Even curved on plan windows are possible and so traditional ‘suntrap’ bay windows can be manufactured.

The double glazed units can be manufactured with clear glass or decorations can be applied such as rectangle or diamond leaded, horizontal or Georgian applied bars. Obscured glass is also available in a variety of options.

W20 doors are used to complement this system where required.
