Spray Foam vs. Fiberglass: Best Insulation for N.E. Florida
If you’re a homeowner in Jacksonville, St. Augustine, or anywhere in Northeast Florida, you’ve probably asked yourself: What’s the best insulation for my home? The answer usually comes down to spray foam insulation vs fiberglass insulation. Both have unique advantages, but when you live in a hot, humid climate like Florida, the right choice can mean lower energy bills, better comfort, and even mold prevention.

Spray Foam Insulation: The Modern Option
- Air Sealing: Spray foam expands into every crack and gap, keeping hot, humid Florida air outside.
- Energy Savings: Homeowners report up to 30% lower energy bills.
- Moisture Control: Helps reduce the risk of mold and mildew.
- Longevity: Can last for decades without sagging or settling.
Fiberglass Insulation: The Traditional Choice
- Affordability: Fiberglass is usually cheaper upfront.
- Familiarity: Contractors and homeowners have used it for decades.
- Good for Large Areas: Works well for attics and walls when installed correctly.
Which Insulation Is Best for Florida?
- If your priority is upfront cost, fiberglass may be the way to go
- If your priority is long-term energy savings, humidity control, and comfort, spray foam is worth the investment. Ask yourself, how long will I be in this home?
