AN INSULATION AND INSTALLATION FRAME FOR A SKYLIGHT WINDOW AND A METHOD FOR INSTALLATION OF A SKYLIGHT WINDOW BY USE OF SUCH A FRAME

摘要

An insulation and installation frame for use in installing a skylight window in a pitched roof structure, comprising a roofing material, a batten structure serving as support therefor, a supporting arrangement of rafters (8) and an underroof placed on top of or between the rafters (8) and comprising at least one exterior, waterproof membrane (3) and an insulation layer (5), comprises top, bottom and side members (28, 29, 30) made from well insulating material and positioned in abutment against the upper side of the underroof and having a light opening (20) of the same size as a light opening made in the underroof (11a) but smaller than the exterior frame dimensions of the skylight window, such that the skylight window may be placed with its frame (11) in abutment against the upper side of the insulation and installation frame (20). At the mounting of the skylight window a marking-out of the window opening in the underroof is carried out by placing the insulation and installation frame (20) in abutment against the upper side of the underroof and by marking along the edges of the light opening (20a) of the frame (20).
