OS2 was designed to meet the specific need to provide historical and monumental buildings with frames that were visibly similar to the old metal window. Today we extend its range from 6 to 36 profiles and add stainless steel to the current list of available materials: galvanized steel, corten steel and brass.
OS2 comes with visible profiles of only 47 mm for the lateral section and 62 mm for the central section, all made with thermal break profiles from the technologically innovative Secco System.
