ABSTRACT:
A frame and sash construction for doors and windows has profiled beams of chair-shaped cross-section, the improvement being that an opening of an elongated slot in a foremost leg portion is directed upwardly towards a seat portion to receive a sealing gasket forming a packing for a window glass or mounting ledge. A backrest portion has a greater height than a rear leg portion. The seat portion is formed with a pair of ribs with opposed flanges to receive locking rods or hinge plates, and the sides of the leg portions facing each other have parallel grooves to receive ribs of the gaskets.
