prodomo ECO air tight and vapour control membrane is a genuine alternative to the most branded air tight membranes with static or variable sd coefficient.
It´s made of polypropylene non-woven fabric and a special functional film . The most competitor membranes are using the same technology, even by calling their membranes "intelligent".
The low sd coefficient of 10 makes the membrane diffusible - a small amount of vapour is able to move through the membrane both ways. This feature reduces the risk of condensation in the building structure.
The prodomo ECO membrane is CE certified and tested in accordance to EN 13984.
Beside the vapour control layer function, the membrane is completely air tight (test report available on request).

What do you need as well, to create a complete air tight layer for your roof/ ceiling?
Black Sealing Tape - to tape the overlaps and penetrations
Belgaseal 310/ 600 - to bond the membrane to the blockwork
Staples - to fix the membrane to joists and rafters
BelgaTape Split - to tape the membrane to (roof) window frames
