Protect Your Roof with a Metal Roofing Underlay
DuPont™ Tyvek® Metal is a roofing drainage underlay which drains away the condensation that can build up beneath the cladding on standing seam metal roofs.
Tyvek® Metal roofing underlay is 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® 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.
Key Benefits of DuPontTM Tyvek® Metal
- Allows movement and reduces material stress by providing separation between metal sheets and timber substrate.
- Reduces rain clatter and sound transmission.

Fitting Tyvek® Metal
Tyvek® Metal roofing drainage underlay is fitted beneath standing seam metal sheet roofs and the underlying timber boarding. The use of 150mm wide timber boarding with 2mm gaps between is recommended.
DuPont™ Tyvek® is a watertight membrane that not only optimises energy efficiency in all building types, but also provides proven durability and long-term protection against external climatic conditions and the effects of condensation.
XIV century St. Wenceslas Chapel is now protected with DuPont™ Tyvek® Metal advanced membrane
Tyvek® Metal had the honour of being used for an extremely important and challenging renewal projects of this kind: the reconstruction of the roof of St. Wenceslas Chapel at St. Vitus Cathedral

Underlayment: Quality and Thickness of Functional Layers Are Critical
Tyvek® membranes are proven to resist ageing better than most common multi-layer underlayments. Even after prolonged exposure to UV radiation and heat, Tyvek® underlayment stays watertight and provides superior condensation control.
- What Makes a Tyvek® Watertight Breather Membrane Unique?
CE Compliant Membranes
All DuPont breather membranes, including Tyvek® and AirGuard®, are fully CE compliant, and carry the CE marking required throughout Europe.
