Can spray foam insulation be used in metal buildings?
The answer is, absolutely and unequivocally, yes. Spray polyurethane foam (SPF) insulation is an excellent way to not only insulate you metal building but also weatherproof it. Spray foam bonds to the surface of the metal walls and roof deck and conforms to the irregular surface profiles. Plus, it also creates the most effective air-seal by eliminating gaps and cracks in the thermal envelope of your metal shop or barn. Furthermore, when applied at the proper thicknesses, it creates a superior vapor barrier which stops condensation and sweating right in their tracks!
Spray foam can be successfully applied to most metal building surfaces. However, there are general installation practices that must be observe. Thus, be sure to hire a qualified and experienced contractor.
