STL-W40
STL-W40 Profile
The STL-W40 range is an evolution of the famous W20 range developed in 1964. Produced for the first time in 1995, it consists of 17 hot rolled profiles and follows the unmistakable classic design of its predecessor. The strong point of this “younger” series is the increased profile depth, which allows accommodating double-glazing up to a thickness of 27mm.
The STL-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 tall and expansive windows.
