Closed-cell spray foam delivers roughly double the R-value per inch (R-6.0 to R-7.0) compared to open-cell spray foam (R-3.5 to R-3.8), making it the stronger performer for thermal resistance, structural reinforcement, and moisture control. Open-cell foam costs significantly less upfront and excels at sound dampening, filling large cavities quickly, and providing a high-performance air seal […]
Most open-cell spray foam insulation problems reported in Charlton, MA homes come down to two things: a foam layer that is too thin to control moisture, and a surface that was dirty or damp when the material was applied. Both errors wreck the air seal, invite rot into the framing, and burn through your budget […]

Unlike traditional insulation materials like fiberglass or cellulose, this foam expands to fill small cracks, gaps, and crevices in the building envelope. By stopping the movement of air through walls, attics, and crawlspaces […]
