VENTILATION MEMBRANES
Product Description
Specialized bitumen membrane designed to create a ventilation layer in bituminous roofing systems. Thanks to uniform perforation over the entire surface, it forms a system of openings that enable the formation of channels ventilating moisture from the substrate. Ensures long-lasting roof durability and safety by eliminating destructive moisture retained in the base layers.
Application
  • as a ventilation (separating) layer in single- or multi-layer roofing systems
