The Dynamic Super Diffusion Membrane is a high-permeability, four-layer undercoating film. Used as wind and waterproof insulation on attic buildings in complex insulated and non-insulated roofs to prevent moisture from entering insulation panels in the attic

Main Benefits:

•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.
