  • Four-layer roof membranes have already earned millions of customers in the United States, and are now conquering Europe. Foliarex offers you new “EXTREME” class products thanks to the most modern roof membrane production technology from the USA. The use of the best components in the world and regular tests – carried out in professional laboratories – guarantee perfect quality of membranes and their reliability for years. 
     Advantages 
    - high water vapour permeability due to which the membrane absorbs moisture and directs it outside through the ventilation gap. 
    - Completely watertight, protects the thermal insulation from the outside against rain or snow. 
    - it has UV stabilizers, slowing down the aging process, caused by weather conditions. 
    - equipped with special anti-reflective coating preventing the occurrence of light reflections.
    - The tape-type membrane is factory-fitted with an adhesive strip, enabling quick and efficient joining of overlaps during roof installation. 
    Usage 
    - diffusion-open membrane, designed as a layer of preliminary covering for the external roofing. 
    - excellent windproof material, intended for walls of buildings in skeletal structures. 
    Due to the low Sd coefficient, this membrane is used in roofs with thermal insulation up to the full rafter height, in which it is laid directly on the insulation.
