What is Closed Cell Spray Foam?
Closed cell spray foam is a dense, rigid insulation that expands to seal cracks and gaps while creating a vapor and moisture barrier. Unlike open cell foam, it’s impermeable to water and provides exceptionally high R-values per inch, making it ideal for both interior and exterior applications.
Benefits of Closed Cell Foam Insulation
- High R-Value Efficiency
Our closed cell spray foam holds a true R-value of 7 per inch, maintaining consistent performance across the full thickness. At just 3.5 inches, it delivers an impressive R-24, making it one of the most efficient insulation options available for homes and buildings in Missouri. - Moisture Barrier Protection
Perfect for basements, crawl spaces, and exterior walls prone to humidity or leaks. - Structural Strength
Reinforces walls and improves overall building rigidity. - Space-Saving Performance
Excellent for tight areas where maximum R-value is needed in minimal thickness. - Long-Term Durability
Won’t sag, shift, or degrade over time—lasting for decades with no maintenance.

FAQ
-
What is the main difference between closed cell and open cell spray foam?
Closed cell foam is denser and acts as a vapor barrier, offering higher R-value and water resistance. Open cell is lighter, more breathable, and better suited for soundproofing and interior use.
-
Is closed cell spray foam good for crawl spaces?
Yes — it's one of the best insulation types for crawl spaces, preventing moisture buildup and improving energy efficiency.
-
How long does closed cell foam insulation last?
Closed cell spray foam can last 30 years or more without settling, shifting, or losing its insulating properties.
-
Can closed cell spray foam be used in basements?
Absolutely. It’s ideal for basement walls and rim joists, providing moisture resistance and high R-value in one application.
-
Does closed cell spray foam add structural strength?
Yes, its rigid nature adds shear strength to walls, helping improve the durability of your building envelope.
