Dormer window construction can withstand high loads exerted by the roof and strong winds, even rooves spanning large distances and not requiring metal profile

摘要

The vertical frame sections (30) forming the lateral sides of the window frames (26) is formed by a central support (32) with a length equal to the distance between the two corner supports (14). The bottom cross-strut (20) forming the bottom side of the window frames comprises a wooden breast strip (22) with cavities (36, 38) for receiving the corner and central supports. At least one window frame is joined to a dormer window frame (12) in the front side of the construction (10), the dormer window frame containing two corner supports with a top cross-strut (18) extending between the top ends of these supports.
