Moisture is the enemy of durability

We used Intello as our air/vapor barrier between the conditioned space and the garage at the Beacon Hill Passive House.

The barrier is air tight but vapor open, meaning it allows moisture to escape.

By allowing the moisture to escape we reduce the likelihood of it getting trapped in the wall assembly and creating mold. By using Intello here we were able to keep a continuous air barrier over the entire conditioned space of the home. We carefully taped and sealed every opening of the barrier to allow for as little air leakage as possible.
