DuPont™ Tyvek® Supro Roof Underlay
An underlay is a key component of the roofing structure, and provides an important element in the weather tightness of a roof cladding system. The underlay acts as a secondary barrier to water ingress from the external environment while also helping to control internally generated moisture. Their function in terms of building durability is important and their on-going performance needs to be preserved to guarantee the life of the building
