Closed-Cell Spray Foam in Albany, NY
Dense, rigid spray foam with high R-value per inch, air sealing and moisture resistance.
Overview
Closed-cell spray polyurethane foam (SPF) is a dense, rigid insulation whose cells are almost entirely enclosed. It insulates, air seals and resists moisture in one application, and can add rigidity to the building assembly. Typically about 1.75–2 lb/ft³; density varies by product. Typically R-6 to R-7 per inch; use the specific product's published R-value. Can qualify as a Class II vapor retarder at sufficient thickness (often around 1.5+ inches). Resists water absorption; not a substitute for proper drainage or waterproofing.
Key benefits
- High R-value per inch
- Can act as a vapor retarder
- Adds rigidity to assemblies
Results depend on your building, its condition and the products used. We'll explain what to expect during your assessment.

Soft, light, lower-cost foam that expands to fill cavities, but stays vapor-permeable and can absorb moisture. Dense, rigid spray foam with high R-value per inch, air sealing and moisture resistance. Albany and the Capital Region have long, cold winters with real freeze-thaw cycles, plus damp basements, crawl spaces and rim joists. Open-cell foam is vapor-permeable and can absorb moisture, so in our climate it carries a higher risk of condensation and moisture problems in rooflines, walls and below-grade areas. Closed-cell foam's higher R-value per inch, vapor resistance and moisture resistance make it the safer, better-performing choice here — which is why it's the only foam we install.
Cost depends on the area size, foam type, thickness and access. We provide a free, written estimate after reviewing your project.
By reducing air leakage and heat transfer, spray foam can help lower heating and cooling use in many buildings. Results vary by home, climate, equipment and habits, so we don't promise specific savings.
