What is Closed Cell Spray Foam?
Closed cell spray foam is the highest-performing insulation available for Arizona homes and businesses. Unlike traditional insulation materials, it creates a continuous thermal barrier with no gaps or thermal bridges.
How It Works
Closed cell spray foam is applied as a liquid that rapidly expands to 30-40 times its original volume. The cells "close" as they cure, creating a dense, impermeable barrier that stops air, moisture, and heat transfer.
- • Liquid application fills every crack and crevice
- • Rapid expansion creates seamless coverage
- • Closed cell structure provides maximum performance
- • Chemical cure bonds permanently to surfaces

| Moisture barrier | ✅ Excellent | ❌ None |
| Structural strength | ✅ High (25+ PSI) | ❌ Minimal |
| Air sealing | ✅ 99%+ | ✅ 95%+ |
| Cost per sq ft | $2.50-$4.00 | $1.50-$2.50 |
| Best for Arizona | ✅ Extreme conditions | ⚠️ Limited applications |
Why Closed Cell is Perfect for Arizona
🌡️ Extreme Heat Performance
Arizona's 160°F+ attic temperatures demand the highest R-value insulation. Closed cell provides R-6.5 per inch compared to fiberglass at R-3.2.
- • Maintains R-value at high temperatures
- • No thermal degradation in desert heat
- • Reflects radiant heat effectively
- • Reduces cooling load by up to 50%
💧 Monsoon Protection
Arizona's monsoon season brings humidity and potential water intrusion. Closed cell acts as a complete moisture barrier.
- • 0.05 perm rating blocks moisture vapor
- • Prevents mold and mildew growth
- • Protects structural elements
- • Won't absorb water like fiberglass
🏠 Structural Benefits
Adds significant structural strength to Arizona homes, important for wind resistance and building integrity.
- • 25+ PSI compressive strength
- • Increases wall racking strength
- • Bonds permanently to structure
- • Resists wind uplift on roofs
🦂 Pest Control
Creates impermeable barrier that prevents pest infiltration common in Arizona desert environments.
- • Blocks scorpions, spiders, insects
- • Seals entry points completely
- • Reduces pest control costs
- • No food source for insects
