ABSTRACT A thermally insulated frame for use in a building comprises spaced inner and outer metal frame members (11, 12), and a thermal barrier (14) provided by a pair of facing, parallel, thermally insulating channel members (16) extending along the gap between the frame members to bridge the gap and interconnect the frame members. Each channel member has a pair of legs respectively received in grooves formed in the two frame members. Each groove has two facing, longitudinally serrated side walls, and each leg has two opposed surfaces both bearing longitudinal barbs for simultaneously interlocking with the facing wall serrations of the groove in which the leg is received. The grooves are dimensioned, in relation to the legs, to enable press-fitting insertion of the legs into the grooves.
