Ecohome recently completed a demonstration home in Wakefield, Quebec, relying heavily on Cosella-Dörken products to attain the very high building standard we had imposed on ourselves.

We designed a wall system using Delta Vent S and Vent SA membranes as air and weather barriers, which were sealed with Delta FlexxBand and Delta MultiBand tape. This helped us create an extremely durable wall system that is about 5 times more airtight than the average new home being built.

With the help of Cosella-Dörken, the Edelweiss House in Wakefield, Quebec was the first house in Canada and only the second house in the world to be certified Platinum under the stringent new LEED Version 4 rating system.
