Fiberglass is the most proven, most reliable attic insulation material available for Naples homes. It won't settle like cellulose, won't off-gas like spray foam, won't absorb moisture in Florida's humidity, and retains its rated R-value for 30+ years. InsulX installs premium blown-in fiberglass in Collier County homes every week — here's why it's the material we trust for every Naples install.

Cellulose insulation settles 20–30% over time, losing effective R-value as it compacts. Spray foam is expensive, can off-gas, and can trap moisture against roof decks in Florida attics. Fiberglass neither settles nor absorbs moisture — it maintains its rated R-value for the life of the home, making it the lowest-maintenance choice for Naples attics.
Premium fiberglass is also fire-resistant without chemical additives, won't feed mold, and doesn't attract pests. For Naples homeowners who want a material that performs identically in year 30 as it does on day one, fiberglass is the answer.
Blown-in fiberglass fills every void in the attic — around wiring, ductwork, joist irregularities, and hard-to-reach perimeter areas common in Naples homes. Batt fiberglass can't match this coverage because it comes in pre-cut sizes that leave gaps around every obstacle.
The result is a uniform thermal blanket with no cold spots, no thermal shortcuts, and consistent R-value across the entire Naples attic floor. That's why every InsulX Naples install uses blown-in fiberglass, not batts.
For Florida's climate zone, we recommend R-49 to R-60 in the attic — roughly 16–20 inches of blown-in fiberglass. That depth creates the thermal barrier needed to cut cooling bills 15–30% in a typical Naples home. Premium fiberglass maintains this R-value for decades without degradation.
Every Naples install includes a depth verification — we measure coverage at multiple points before calling the job complete, so you know the R-value you paid for is the R-value you got.
Yes. Premium blown-in fiberglass is fire-resistant without chemical additives, won't absorb moisture, won't feed mold, and doesn't off-gas. It's the safest, most proven attic insulation material available for Naples homes.
Fiberglass outperforms cellulose in every category that matters for Naples homeowners: it doesn't settle (cellulose loses 20–30% of its R-value over time), doesn't absorb moisture, and retains its rated R-value for 30+ years.
For Florida, we recommend R-49 to R-60 in the attic — about 16–20 inches of blown-in fiberglass. This is the Department of Energy recommendation for your climate zone and delivers the biggest cooling savings.
