Open cell foam is the right choice for interior wall cavities, attic roof deck applications (conditioned attic), and interior floor assemblies in Portland area homes. For basements, crawl spaces, and rim joists in Portland's cold climate, closed-cell foam is the better choice.

Massachusetts requires a minimum of R-49 in attics. Open cell foam achieves R-3.7 per inch — requiring approximately 13 inches to meet code. Given Portland's cold coastal Maine winters with lows reaching -10°F, we typically recommend installing to R-49 to R-60 for maximum energy savings.
