11 profiles for classic design & the highest performance

Designed in the 1990’s as an evolutionary development from W20, Our W40 range also fully hot rolled in Switzerland offers continuity of style with the same look, options and benefits as our W20 range but allows for much thicker high performance double or triple glazing (up to 32mm).

For a timeless look and performance nothing beats our W40 system.

Solid hot-rolled profiles that deliver unparalleled elegance through minimalist design

The W40 range and it’s older sibling the W20, are inspired by the Standard Metal Windows range, which first entered the market after the First World War between 1914-1918.

Thanks to its simple and slender design, both the W40 and W20 feature heavily in both a heritage and contemporary architectural projects. Boasting elegant and compact sightlines, W40 and W20 profiles provide safety and comfort due to its excellent thermal and acoustic qualities.
