A SEALING COLLAR FOR BEING MOUNTED AROUND A WINDOW FRAME MOUNTED IN AN INCLINED ROOF OF A BUILDING, AND A METHOD FOR MOUNTING A WINDOW FRAME

摘要

The invention relates to a sealing collar (10) adapted for being mounted around a window frame (3) mounted in an inclined roof of a building, and to a method for mounting a window frame (3) using such a sealing collar. The sealing collar comprises an inner portion (11) having an inner edge which defines an opening and which is adapted for surrounding the window frame, and an outer skirt portion (12) attached to the outer edge of the inner portion and made from a waterproof membrane. Top, bottom and side members of the inner portion are made from a substantially dimensionally stable material and the shape and size of the opening substantially matches shape and size of the window frame, when the sealing collar is in the mounted condition, so that the inner edges of the inner portion may be used as a guide for a drawing aid or cutting tool.
