Membranes

Our range of air and windtight membranes includes liquid, fire proof (upto A2), and both internal and external membranes. Our breathable airtightness membranes, tested and manufactured to the highest standards, are essential for Passivhaus construction.

It is essential to have an effective vapour check membrane to maintain the building’s thermal performance. This also means the building is better protected from damaging vapour build-up. Some of the breathable airtightness membranes in our range are humidity variable. They adapt to the seasonal changes in the climate, offering extra security for the home.

Our liquid airtight membranes can be sprayed and painted, and they are ideal for areas where fitting other membranes would be impossible.

Fireproof membranes must be used in the manner described in the data sheets in order to maintain the stated fire rating.
