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 homeowners in Charlton fail to account for local climate factors when installing open-cell foam. The biggest mistakes involve insufficient thickness to control moisture and applying the material to dirty or damp surfaces. These errors lead to poor air sealing, structural rot, and wasted money. Lamothe Insulation regularly sees these specific issues during inspections and […]
Open-cell spray foam services help reduce indoor dust by creating a functional air seal that blocks the entry points for outdoor pollutants. 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 […]
