DuPont™ Tyvek® Supro
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.
DuPont™ Tyvek® Supro
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.
