This is The ...New Improved ThermaDry
This is a vapor barrier for basement walls - but with a difference.
ThermaDry Has solved the problem of condensation which all plastic vapor barriers are prone to.
It has close air cells which go against the foundation wall, keeping the internal face away from the cold masonry, plus it has a thermally reflective layer of 99% pure Aluminum foil which reflects radiant heat back into the room.
When lined with sheet rock or other board system with a small air space between the board and the foil face, the reflected heat warms the air space, which in turn keeps the inside surface warm and thus prevents condensation in all normal living conditions.
ThermaDry takes a lot less labour to install as compared with the heavier Polyethylene membranes...
Being ultra - lightweight and only 1.35m wide x 25m long it is...
> very easy to handle
> easy to cut fold and join
> there is less drilling as the fixings are only 6mm diameter and require a hole only 10 - 15mm deep
If you have never installed this product before, you must experience it to appreciate the benefits, once you have, you will never want to install another HDPE membrane again - leave that for the Dinosaurs!
