Clement W40 steel windows  

 

A heavy duty framing system introduced in the 1990s, W40 windows are ideal for public buildings, but equally may be used in all types of building where strong, durable frames, efficient opening casements and robust fittings are required.

With a wide 40mm profile to provide extra strength, W40 windows are suitable for new build projects or refurbishment projects, where the original fenestration is to be maintained and windows may be manufactured to fit existing apertures
