Technical description
Roof access window base:
-
Made of galvanized steel sheet with a thickness of min. 1.25mm (standard: straight or slanted base with a height of 150, 350, 500 and 750mm. The base should be insulated with a layer of mineral wool or polystyrene foam with a thickness of 40mm.
Made of PVC (straight base with a height of 200mm or slanted base with a height of 150 or 300mm). The base does not require insulation.
Clamping frame:
The bases have special cut-outs in the corners, which, after installation and machining of the base, allow free press-on installation of the so-called PVC "clamping" frame.
Tilting segment:
The tilting segment consists of a hinged frame and a cover. Cover is made of cellular polycarbonate, solid polycarbonate or acrylic. Choose from two color options: transparent or milky. The surface can take the shape of a convex, dome-shaped (from acrylic or solid polycarbonate) and flat (from cellular polycarbonate). The roof hatch made of cellular polycarbonate can appear in Broof(t1)/fire retardant classification.
The frame is made of PVC or aluminum profile. It is protected around the perimeter with gaskets, which prevents water from entering the rooflight.
Drive:
Opening roof access windows to access the roof is done manually. To reduce the force required to open the cover and increase user comfort, gas springs and a handle are used
