Multivap Super is a strong, vapour permeable and water-resistant triple layer underlay for the cold side of pitched roofs and in vertical walling applications. It provides protection to the structure from wind driven rain whilst allowing moisture from within the structure to escape.
MultiVap Super is a strong, vapour-permeable and waterproof four-layer membrane with a PP spunbond membrane and microporous film. The membrane is applied to the outside (the cold side) of sloping roof and façade constructions. This protects the interior construction against external moisture, while allowing water vapour from inside to escape safely. This ensures that the construction remains optimally protected and well ventilated.
