ABSTRACT:
To reduce heat transmission between an inside area (J) and an outside area (A) in an aluminum casement window or door frame construction, the frame is formed of three seperate rail elements (6, 7, 8) which are structurally interconnected by glass fiber reinforced polyester strips (9, 10) which are positioned to cooperate with steps (20a, 20b, 20c) formed on a wood window or door frame so that, upon closing the window or door, two air chambers (12, 14) will be formed, separated by an intermediate projecting strip (37) projecting from the intermediate rail (7); additional sealing strips (16) can be provided, the strips being retained between legs (22, 26) formed on the rails and defining grooves therebetween.
