摘要

A composite section door or window frame 1 comprising at least two spaced apart metal sections 2, 3 connected by at least two spaced apart insulating portions 5, 6, is made from two spaced apart initially integral metal sections 2, 3 joined by one or more metal bridging webs, the one or one of which defines the bottom of a first, upwardly-open, groove (b) by filling the first groove with settable insulating material 6 (6', 6'', 18). cutting away the metal bridging web(s), turning the section over about its longitudinal axis, introducing a strip (8; 8', 8'') of material to form the bottom of a second, upwardly open, groove and filling it with settable insulating material (5; 16, 17).
