This 3-in-1 wall system combines rigid foam insulation, flashing, and spray polyurethane foam into one product with an R-value ranging from 9-24. This saves the 4-5 trips around the building typically required to install the drywall, air barrier, vapor retarder, and insulation. THERMAX Wall System prevents air infiltration and moisture intrusion and can be sprayed at below-freezing temperatures. The system meets ASHRAE 90.1-2007 prescriptive requirements for continuous insulation and the ASTM E331 Water-Resistive Barrier Test.
