When installing a plastic window or door with excellent thermal insulation, few people think that improper window installation can worsen the overall thermal insulation value. Of course, this does not happen at first, but only after a few years when the polyurethane insulating foam (PUR-foam) loses a lot of its insulating effect due to moisture. An innovative process - the German RAL standard - preserves the PUR-foam and thus the insulating capacity of the door and window. The window installation system is recommended for all plastic window replacements, whether it is a mid-range or high-end PVC window.
