Closed Cell Spray Foam

---

Spray foam insulation is created by combining two composite materials: polyurethane and isocyanate. When these materials mix, they chemically react and expand, forming a hardened foam once applied. The mixture is sprayed through a specialized spray foam gun, where it quickly expands and adheres to the surface, creating a highly effective insulation barrier.

There are two main types of spray foam insulation: open-cell and closed-cell.

• Open-cell spray foam is less dense and has a spongy texture. Its main advantages are sound dampening and affordability, making it an excellent choice for noise reduction.
   
• Closed-cell spray foam is denser, more durable, and although more expensive, offers superior benefits that often outweigh the cost.
   

• Extremely Powerful Insulator – Provides a tight seal in even the smallest cracks and gaps. Closed-cell foam has a much higher R-value compared to other types of insulation.
   
• Energy Savings – Homeowners often report reducing their energy bills by 50% or more after installation.
   
• Air-Tight Seal – Blocks air leaks, dust, pollen, and other allergens, helping your HVAC system run more efficiently.
   
• Moisture Resistant – Unlike traditional insulation, closed-cell foam does not absorb water, making it waterproof and ideal in areas prone to flooding.
   
• Mold Deterrent – Because it’s made from an inert polymer, it provides no food source for mold, mildew, or bacteria.
   
• Long Lifespan – Once installed, closed-cell spray foam can last for decades without needing to be replaced.
   
• Added Structural Strength – Not only does it insulate, but it also reinforces walls and roofs while reducing noise pollution.
   

Closed-cell spray foam insulation is recognized by the Federal Emergency Management Agency (FEMA) as a reliable flood-resistant material. Research from the University of Florida also shows it reduces structural damage caused by high winds and flooding—providing long-term protection for your home.
