DuPont™ Tyvek® Supro and DuPont™ Tyvek® Pro Wall Underlays
Drawing from more than 20 years of international manufacturing experience in the field of construction, DuPont™ Tyvek® Supro and DuPont™ Tyvek® Pro are wall underlays that have been proven worldwide to be durable and to perform in extreme environments.
DuPont™ Tyvek® Supro Wall Underlay
An underlay is a key component of the wall structure, and provides an important element in the weather tightness of a wall 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
