The classic W40 range is an evolution of the famous W20 range developed in 1964. Produced for the first time in 1995 it consists of 17 profiles and follows the unmistakable classic design of its predecessor.
Our W40 suite is not only used in the field of restoration, but it’s also highly acclaimed in contemporary architecture for its elegant and compact sightlines, ensuring safety and comfort thanks to its excellent thermal and acoustic performance. Despite the depth of this system is only of 42 respectively 47 mm, technically it is considered a “heavy duty” range, which allows making large windows thanks to the extraordinary strength of steel.
Any kind of inward or outward openings: sidehung, double-vent (French style), bottom-hung, top-hung or projected top-hung, horizontally and vertically pivoted windows, as well as large sliding and folding doors. W40 profile features increased profile depth, which allows it to accommodate double glazing up to a thickness of 27mm.
