Tyvek Supro Breather Membrane Felt Underlay 1.5m x 50m

Reinforced with laminated nonwoven polypropylene, this durable Supro breather membrane felt underlay from DuPont Tyvek is extremely water-resistant, as well as vapour-permeable and airtight. It is ideal for use with all unsupported and supported roofs without needing any ridge, tile or soffit ventilation. As a result, you can save on both time and money throughout the construction process.

This Tyvek Supro underlay can be used for a wide variety of applications including cold, hybrid and warm roofs. It is also perfect for wall and floor installations, low-pitched metal roofs and Scottish sarking board systems. Designed to withstand high temperatures and prolonged UV radiation while also offering superior moisture and air management for residential and commercial buildings, it comes with full IAB and BBS approval for use in all pitched roof structures.
