The top, bottom and side members of the frame structure comprise wood profiles with substantially parallelogram-shaped cross section, the exterior edge surfaces (17-19) being positioned in a common plane, with which adjacent opposite side faces (26, 27) of the profile cross section form an angle (v) of 95 to 140.degree..
