Closed-Cell Spray Foam Insulation
Closed-cell spray foam is a high-performance insulation system designed for superior air sealing, moisture control, and long-term thermal efficiency in Spokane-area homes and commercial buildings.
Engineered for Maximum Performance
Closed-cell spray foam forms a dense, continuous insulation layer that expands to seal air leaks and reinforce the building envelope. Once cured, it creates a rigid barrier that supports consistent indoor comfort in all seasons.
With an exceptional R-value per inch, closed-cell foam delivers outstanding thermal resistance even in compact wall cavities, rim joists, crawl spaces, and roof assemblies.
This system is often selected for projects where performance, durability, and long-term efficiency are the highest priorities.
