DuPont™ Tyvek® Pro Roofing Underlay 60m²

The Tyvek® Pro diffusion-open underlay is a water- and windproof, breathable roofing underlay that allows water vapor to pass through. The breathable underlay enables full-thickness installation of roof insulation without the need for a ventilation gap between a traditional (condensation-protected) underlay and the thermal insulation.

The functional layer of the Tyvek® Pro underlay is approximately six times thicker than that of most micro-porous underlays on the market. The functional layer is made entirely of UV- and heat-stabilized polyethylene, making it highly resistant to UV radiation and temperature variations.

The fiber-reinforced, diffusion-open structure of the Tyvek® Pro underlay allows the implementation of an energy-efficient closed underlay system, where cold and humid outside air is not separately introduced to the attic for ventilation. It can also be used as a wind barrier.

Made from polypropylene (PP) fabric + polyethylene (PE). The material is recyclable.
