HOLLOW CHAMBER PROFILE, IN PARTICULAR FOR THE FACADE, WINDOW AND / OR DOOR STRUCTURE AND FOR COMPONENTS IN THE AREA OF THE SUN PROTECTION, AND METHOD FOR PRODUCING A HOLLOW CHAMBER PROFILE, AND DEVICE FOR CARRYING OUT SAID METHOD

摘要

A hollow chamber profile (12, 21, 31, 41, 51), in particular for facade, window and / or door construction and for components in the field of sun protection, comprising PVC-containing profile walls (23, 33) which have at least one hollow chamber (24, 34), the hollow chamber (24, 34) being at least partially filled with a PVC and / or polyacrylate-containing foam (11, 22, 32) to increase the thermal resistance, characterized in that the foam (22, 32) is used as a foaming agent Thermally expandable microspheres (10), the microspheres (10) being contained in the mixture in a proportion of less than 20% by weight, as well as a method for producing a hollow chamber profile (12, 21, 31, 41, 51) and a device (1) to carry out the procedure.
