The window's sleek design is finished with RAL7022 exterior aluminum and 2 layers of white acrylic varnish on the interior. For easy operation, the handle is conveniently located at the bottom and offers 2 micro opening positions. The glass construction, 4HO-Tg14Ar-33.1T, provides an acoustic rating of 35Db (-1.-3). This window can be installed on roofs with pitches ranging from 15-151.
