South Florida Insulation Authority

Blown-in fiberglass insulation engineered for Florida's subtropical climate.

InsulX Insulation Services is Florida's blown-in insulation authority. We install premium blown-in fiberglass attic insulation across all 67 Florida counties — from Miami-Dade and Broward on the Atlantic coast to Collier, Lee, and Pinellas on the Gulf coast. Our climate-engineered approach combines air sealing, blown-in fiberglass to R-49, and balanced attic ventilation to cut Florida cooling bills 15–30% and keep upstairs bedrooms comfortable year-round.

Florida attics can exceed 150°F in summer, turning under-insulated ceilings into radiators that force HVAC systems to run constantly. Blown-in fiberglass fills every gap, void, and joist irregularity that batt insulation misses — delivering a uniform thermal blanket with no thermal shortcuts. Unlike spray foam, it preserves the attic ventilation Florida roofs need to manage humidity and shingle heat. Unlike cellulose, it won't settle, absorb moisture, or feed mold in Florida's subtropical climate.

Every InsulX install includes a free attic inspection, an itemized quote locked before work begins, air sealing of all penetrations, premium fiberglass blown to verified depth, and a 90-day performance guarantee. Most Florida homes are completed in a single day with next-day scheduling available.
