Fort Myers homeowners asking "what's the best insulation for my home?" are usually comparing fiberglass, cellulose, spray foam, and radiant barriers. The honest answer depends on your climate, budget, and goals — but for the vast majority of Lee County attics, blown-in fiberglass to R-49+ is the best choice. Here's an objective comparison to help you decide for your Fort Myers home.

Florida's heat and humidity demand insulation that won't absorb moisture and won't settle. Blown-in fiberglass is the best material for this climate because it's naturally non-absorbent, doesn't settle, retains R-value for 30+ years, and is fire-resistant without chemical additives.
Cellulose absorbs moisture and settles 20–30% — poor choices for Florida. Spray foam offers high R-value per inch but costs 3–5x more and can trap moisture against the roof deck in Florida's humidity. For most Fort Myers homes, fiberglass is the clear winner.
Best cost-to-savings ratio: blown-in fiberglass ($2,200–$7,800, 3–5 year payback). Best R-value per inch: closed-cell spray foam (R-6.5/inch, but 3–5x the cost). Best longevity: blown-in fiberglass (30+ years, no settling). Best moisture resistance: blown-in fiberglass (non-absorbent). Best air sealing: spray foam (but air sealing is included with every fiberglass install).
For Lee County homeowners, the best overall choice — balancing cost, performance, longevity, and climate suitability — is blown-in fiberglass to R-49+ with professional air sealing.
The best insulation for your Fort Myers home depends on your current attic condition, budget, and goals. If your attic has less than R-30, a blown-in fiberglass top-up to R-49+ is the best investment. If you have attic ductwork, adding a radiant barrier can further reduce cooling costs.

For most Fort Myers homes, blown-in fiberglass to R-49+ is the best choice. It delivers proven R-value for 30+ years, doesn't absorb moisture in Florida's climate, doesn't settle, and offers the best cost-to-savings ratio of any insulation material.
Spray foam offers the highest R-value per inch but costs 3–5x more than blown-in fiberglass and can trap moisture against the roof deck in Florida's humidity. For most Fort Myers attics, blown-in fiberglass delivers the same energy savings at a fraction of the cost with no moisture risk.
