Abstract: In a method for the production of thermally insulated composite sections a free space (4) formed between at least two metal sections (1,2), held spaced apart, and sealed at the bottom is filled from its open side with an insulating material (10) which at first is in liquid form and then hardens. In order to produce such sections, particularly also those of large size, with the least possible expense for labor and material, and at the same time to achieve the most favorable heat insulation values in the insulating region, solid insulating material layers (12,13) positively and frictionally joining together the metal sections (1,2), and insulating layers (14) hardening with a porous structure are introduced in succession into the free space (4), each layer only partly filling the free space.

Abstract: An insulative frame-strip assembly comprises metallic inner and outer side members splined together by a rigidly-acting insulating or frost-barrier splicing strip. These three main parts are extrusions assembled by transverse movements, instead of being threaded end for end or requiring molding of the splicing strip in situ.

The locking may use interlocking formations or only friction, and either may be aided by torsional pressure. The locking strip is inserted through the pane-receiving channel so that inserting the pane therein prevents removal of the locking strip and adds to its locking forces. Hooked webs on the two metal side members extend transversely in slightly spaced parallel planes, the end of each being a flange extending toward the other web and snugly engaging the spline strip to use its compressive strength.
