Pre-insulated PE-X / AL / PE pipes - LASER Invena are used to transport liquids in heating and sanitary installations inside buildings. The applied insulation layer of soft, foamed polyethylene (EPE) provides excellent thermal and acoustic insulation in a wide temperature range. Thanks to the closed cell structure, the insulation is characterized by minimal water absorption and water vapor permeability. The pipes are highly flexible, which facilitates assembly work. Pipes recommended for use in heating and sanitary installations in wooden construction, traditional (brick buildings), in places with difficult access.
