Composite frame profile for windows, doors and facades of buildings has metal profiles connected together by webs of insulating material and with separation walls between locating grooves

摘要

The metal profiles (1,2) have separating walls (11) with triangular-section enlarged ends facing each other. They have grooves (5a,5b) on either side accommodating adjacent flange sections (4) on the ends of the insulation webs (3a,3b). Each of the grooves has a flat base (12). The insulation webs incorporate seals (28) and hold a heat-insulating layer (31) between them.
