William Collins was first introduced to the concept of an air barrier in 2009. What really caught his attention about this concept was that this was in fact what they had been doing on poultry farms for almost 6 years but in fact, there was never a name or concept for this spray idea. As William began to study how and air barrier worked and then what the Air Barrier Association of America was starting to make happen in the world of commercial buildings, it became apparent to him that this was something that had a lot of merit for the future of all new and existing buildings.
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 building enclosure boundary that separates indoor (conditioned) air and outdoor (unconditioned) air. In multi-unit/townhouse/apartment construction the air barrier system also separates the conditioned air from any given unit and adjacent units. Air barrier systems also typically define the location of the pressure boundary of the building enclosure. Energy efficiency is accomplished when a building enclosure is tight. Air Barriers are an emerging sealant technology which will change the way that buildings are constructed.
