As building codes continue to become more stringent, and states and localities continue to adopt codes requiring increased energy efficiency and low emissions, Gaco 183M provides a multi-functional solution to the rising cost of building materials required to meet today's demand for high-performance buildings. Not only does Gaco 183M offer the exceptional all-around performance that spray foam applicators demand, architects and specifiers will appreciate its design flexibility and sustainable contribution to healthy building interiors, along with the energy efficiency and occupant comfort that owners desire. An air barrier system stops the uncontrolled flow of air into and out of the building envelope, thereby reducing moisture problems, building heating and cooling costs, and greenhouse gas production; it improves indoor air quality, acoustical isolation and the indoor environment; overall, an air barrier system results in sustainable, durable buildings.
