TYVEK® SUPRO
DuPont™ Tyvek® Supro Roof Underlay
Drawing from more than 20 years of international manufacturing experience in the field of construction, DuPont™ Tyvek® Supro is a roof underlay that has been proven worldwide to be durable and to perform in extreme environments.
DuPont™ Tyvek® Supro Roof Underlay
Tyvek® Supro, Tyvek® Supro Plus, and Tyvek® Supro Metal are roofing drainage underlays that drain away the condensation that can build up beneath the cladding on roofs.
The roofing underlays are vapour-permeable, yet water-resistant and airtight. When used in combination with genuine Tyvek® accessories it can help to reduce condensation, improve overall airtightness, add thermal efficiency, and protect structural integrity.
Besides allowing condensation beneath stainless steel, aluminium, copper, and zinc roofs to drain away, Tyvek® Supro Metal also reduces sound transmission such as rain clatter, and minimises material stress by permitting a degree of movement between the cladding and the timber beneath.
