WebMar 8, 2016 · Thank you for an excellent article. In a recent conversation with a structural engineer, she expressed a different reservation regarding the use of ccSPF. On a project several years ago I called for 2" of ccSPF on the underside of the plywood roof sheathing, backed by batt insulation in the rest of the cavity created by the 14" LVL roof rafters. WebClosed-cell spray polyurethane foam (ccSPF) is used to insulate, air seal, manage moisture, and improve structural strength in commercial and residential buildings. It is an all-in-one insulation solution that expands to fill crevices, preventing air and moisture infiltration. Blowing agents form the foam cells or bubbles in spray foam ...

WebApr 11, 2024 · This approach utilizes ccSPF for its barrier properties, while also acting as insulation. A slab that has been insulated with 1.5 inches of ccSPF has in average an R-10 rating, which meets most code requirements for slab insulation. In many regions, 1.5 inches of ccSPF is adequate to address the requirements for a subfloor vapor retarder.
