The W40 range was produced for the first time in 1995 and consists of 17 hot rolled profiles. It follows an unmistakable classic design. The strong point of this series is the increased profile depth, which allows accommodating double-glazing up to a thickness of 24 mm. The W40 suite is not only used in the field of restoration, but it is 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 tall and expansive windows. Powered by OTTOSTUMM.
