Prefabricated insulated skylight

Easier opening with spring control prevents unexpected slamming of the window and facilitates exit through an opening of a comfortable size of 650 x 1180 mm. The practical one-handed control of the side-opening sash is anchored on the left. The serially mounted insulation block around the entire perimeter of the sash prevents heat loss and cold penetration into the interior. The insulation values of the glass are Ug = 1.1 W/m²K and of the frame Uf = 1.3 W/m²K. The frame and sash are made from a three-chamber PVC profile with increased impact resistance and sound insulation class 3. The passage is supplied in the color white (inside) and anthracite (outside). The use of insulated hatch windows is possible for roofs with a slope from 12° to 60°. The passage is supplied including flashing and trimming, through which it integrates into the roof covering with the same finish and color.
