Air barriers are systems of materials designed and constructed to control airflow between a conditioned space and an unconditioned space. The air barrier system is the primary air enclosure boundary that separates indoor (conditioned) air and outdoor (unconditioned) air. The above skit was filmed at the location of our current Net Zero Build in Ottawa. This was the first time we did an air barrier system with this product. For further information, In the video below Casey explains the differences between an air barrier and a vapour barrier.
