Closed-Cell Spray Foam
Closed-Cell Spray Foam Insulation in Naples, FL
The highest-performing insulation available for Florida’s hurricane zone. Closed-cell spray foam delivers unmatched R-value, a total moisture barrier, and structural reinforcement that can protect your home when it matters most.
What Is Closed-Cell Spray Foam?
Closed-cell spray foam is a rigid, dense insulation where the cells are completely closed after curing. This gives the foam its defining characteristics: a high R-value of about R-6.5 per inch, impermeability to water and vapor, and structural strength that can reinforce the walls and roof of your home.
In Naples, Fort Myers, and the rest of Southwest Florida — sitting squarely in hurricane territory — closed-cell spray foam is the preferred insulation for any exterior application. When a Category 3 or 4 storm approaches, you want your walls and roof reinforced by more than just framing lumber.
