Exterior applications of spray foam form a layer of continuous insulation and air barrier. A layer of continuous exterior insulation will control thermal bridging – the heat loss through though wood and steel studs and beams.

Spray foam is applied onsite starting as a liquid then expanding and conforming to the surface where it’s applied.  Spray foam’s application method makes it an ideal solution for exterior applications because it can be applied without taping or sealing joints and it conforms to complex, unusual geometry… even round walls!
