Looking for the most energy-efficient insulation for your Fresno home? With triple-digit summers, poor air quality, and rising utility costs, Fresno homeowners need more than just basic insulation — they need a smart, long-term solution.
That’s where spray foam insulation stands out. At Supreme Spray Foam Fresno, we help homeowners cut cooling bills by up to 50%, seal out harmful allergens, and add value to their property — all while staying comfortable year-round.
This guide explains why spray foam outperforms fiberglass or cellulose in Fresno’s climate, how it saves money over time, and what to know before installing it in your home.
Spray Foam vs Traditional Insulation: What Works Best in Fresno’s Heat
Fresno experiences hot, dry summers with temperatures often soaring past 100°F. This creates a year-round need for efficient thermal protection. Spray foam insulation offers a superior air seal compared to fiberglass or cellulose, keeping conditioned air inside and extreme heat out.
Key benefits at a glance:
- Energy Savings: Reduce heating and cooling costs by up to 50%.
- Air Tightness: Eliminates air leaks that drive up energy usage.
- Moisture Barrier: Resists mold and mildew by sealing out moisture.
- Longevity: Lasts 30+ years with minimal maintenance.
Understanding Your Insulation Options
Here’s how spray foam stacks up against other materials:
| Feature | Spray Foam | Fiberglass | Cellulose |
| Air Seal | Excellent | Poor | Poor |
| R-Value per Inch | 6.0+ | 2.2 – 2.7 | 3.2 – 3.8 |
| Moisture Resistance | High | Low | Low |
| Lifespan | 30+ years | 10–15 years | 20–30 years |
| Installation Complexity | Moderate | Easy | Easy |
| Upfront Cost | Higher | Lower | Lower |
Bonus Tip: While spray foam costs more upfront, the ROI is often seen in just a few years through energy bill savings.
What You Need to Know
| Spray Foam Type | R-Value per Inch | Best For |
| Closed-Cell | ~6.0–7.0 | High insulation + moisture barrier |
| Open-Cell | ~3.5–4.0 | Soundproofing, interior walls |
R-value measures thermal resistance the higher, the better. Closed-cell foam is denser and more water-resistant, making it ideal for Fresno’s dusty, arid environment.
