Spray Foam Products
Open-cell and closed-cell spray foam systems specified for Washington homes and commercial buildings — not a one-size slogan.
Open-Cell Spray Foam
Common for attics and interior cavities where air sealing and sound control matter. Lower density, excellent coverage in irregular framing.
Closed-Cell Spray Foam
Higher R-value per inch and strong moisture resistance — often used in crawl spaces, rim joists, and tight exterior assemblies in PNW wet winters.
Heatlok HFO Pro Closed-Cell Spray Foam
Heatlok HFO Pro from Huntsman Building Solutions is a closed-cell spray foam with an aged thermal resistance of 1” = 7.4 ft²h°F/BTU and a Class II vapor retarder rating at 1”, per Huntsman’s technical data sheet. See our Heatlok HFO Pro page for specs and where it fits, download the Heatlok HFO Pro Technical Data Sheet (PDF), or view Heatlok HFO Pro on the Huntsman Building Solutions website.
