Protect Your Investment With a Water Resistant Membrane
Tyvek® Supro is the market-leading breather membrane, helping to protect roofs against wind and water, and also improve energy efficiency.
Tyvek® Supro is a durable, water resistant membrane that is reinforced with a laminated polypropylene nonwoven. This airtight, vapour-permeable membrane is extremely water-resistant, and can be used for all supported and unsupported pitched roofs.
Tyvek® Supro does not need any soffit, tile or ridge ventilation, which can save time and money in the construction process. In addition to warm, hybrid and cold roofs, applications include Scottish sarking board systems, low-pitched metal roofs, and wall and floor applications.
Tyvek® Supro Plus
Tyvek® Supro Plus offers the same benefits, plus an integral adhesive lap tape designed for use in the Tyvek® sealed roof system. Sealing all horizontal laps contributes to the system’s thermal efficiency by reducing air infiltration.
Temperature and UV-Resistant
Tyvek® Supro and Tyvek® Supro Plus water resistant membrane products are designed to withstand prolonged UV radiation and high temperatures, and come with full BBA and IAB approval for use in all pitched roof constructions.
