DuPont Tyvek Supro Plus Breather Membrane Felt Underlay - 50m x 1.5m Roll
Description
Tyvek Supro plus 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 plus 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 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.
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.

Questions & Answers
Question:
Relating to BS5250 :Tyvek Supro is vapour permeable but not air permeable. Therefore under NHBC standards (2011) am I correct in saying that where there is not eaves to eaves ventilation a continuous opening of 5mm must be provided at ridge level? I have seen Tyvek Pro installed where both ridge and eave ventilation have been removed.
Answer:
If installing this membrane we would advise to also have eaves and ridge ventilation to allow the roof to breathe.
