Protect TF200 Extreme is a high performance, waterproof, breather membrane designed for use externally on timber frame walls, Structural Insulated Panels (SIPs), Cross Laminated Timber (CLT) panels and steel frame construction.

Designed for use externally on buildings situated in areas which are typically high altitude, exposed and open to high winds, within westerly coastal sites in England, Ireland, Wales and Scotland, particularly cliff and sea front locations. Suitable for use where Class W1 water penetration resistance is specifically recommended.

Protect TF200 Extreme has been developed from the tried and tested TF200 range and additionally utilises microporous film technology.

Produced in the UK of triple ply construction, Protect TF200 Extreme is installed on the cold side of the insulated panel to minimise the risk of interstitial condensation and allow water vapour to escape into the vented cavity, providing a secondary line of defense against rainwater penetration during the life of the building after the external masonry is built.
