Builders constructing new homes in Worcester, MA are increasingly turning to open-cell spray foam insulation to meet the state’s demanding energy code requirements while delivering homes that perform at a higher level than traditional fiberglass or cellulose assemblies. Open-cell spray foam, typically delivering R-3.6 per inch, expands to fill cavities completely, creating an air-impermeable seal […]
Yes, open-cell spray foam is air-impermeable when installed at the proper thickness, typically between 3.0 and 5.5 inches depending on the specific product. It meets the International Residential Code definition of an air-impermeable insulation material, which requires an air permeance of 0.02 L/s-m² or less at 75 Pa pressure differential when tested per ASTM E2178 […]
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 generally provides superior noise reduction compared to closed-cell foam. Its lower density and open If you’re comparing open-cell vs closed-cell foam for soundproofing, the short answer is that these two materials handle sound in completely different ways. Open-cell foam absorbs sound waves inside its soft, porous structure. Closed-cell foam is dense enough […]
Open-cell spray foam prevents air intrusion by expanding up to 100 times its liquid volume during application, creating a custom-fitted air barrier. This rapid expansion allows the material to fill every gap, crack, and crevice within a wall cavity or attic space that traditional insulation often misses. By adhering directly to the building substrate, it […]
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 […]
Property owners in Springfield see a notable increase in resale value after open-cell spray foam insulation installation, which addresses the two most significant concerns for New England buyers: high heating costs and indoor comfort. By sealing air leaks that traditional insulation misses, open-cell foam creates a more efficient thermal envelope, lowering energy bills and enhancing […]
Investing in quality open-cell spray foam insulation pays for itself through superior air sealing, which significantly lowers monthly energy bills and improves indoor air quality. Unlike traditional insulation materials that can leave small gaps, open-cell foam expands to fill every crack and crevice in a building’s envelope. This creates an airtight barrier that stops conditioned […]
