Compound profile for frames of windows, doors facades etc.

摘要

A composite section for frames of windows, doors, facade elements and the like consists of two metal section parts and at least one plastic insulating web that interconnects said metal section parts and whose ends are held in corresponding grooves of the metal section parts. The plastic material of which the insulating web is made is combined with a composite fibre skeleton made of heat-resistant fibres. The composite fibre skeleton is form-fittingly and frictionally anchored in the grooves of the metal section parts, so that it retains together the metal section parts even when the insulating web plastic material degenerates. The composite fibre skeleton has at least one strip with thicker marginal sections frictionally anchored in the grooves of the metal section parts.
