Blown-In Insulation
Fast, affordable attic insulation upgrades starting at just 95¢ per square foot. Cellulose and fiberglass options available.
Blown-in insulation is loose-fill cellulose or fiberglass installed with a blower machine, fed through a hose run into the attic. It is the fastest, most cost-effective way to bring an existing Miami attic up to current R-value standards — and the best choice when the goal is a quick, quiet upgrade with no drywall demolition. In South Florida's hot, humid climate, the difference between an under-insulated attic and one built up to R-38 or R-49 shows up directly on your monthly cooling bill.
Atlas Insulation installs both treated cellulose (recycled paper fiber treated with borate for fire and pest resistance, denser and slightly better at slowing air movement) and fiberglass loose-fill (lighter, will not absorb moisture, and resists settling). For most South Florida attics we recommend topping up the existing insulation rather than removing it — assuming the old layer is dry, clean, and free of rodent damage.
Where Blown-In Insulation Works Best:
- Attic floor top-up — Add inches over existing insulation to reach R-30, R-38, or R-49
- Older Miami homes — Bring 1970s/1980s attic R-values up to current Florida code
- Around obstacles — Flows around recessed lights, top plates, wiring, and HVAC ducts
- Cathedral ceilings — Dense-pack between rafters in finished ceiling cavities
- Retrofit wall cavities — Drill-and-fill dense-pack in existing walls without gutting drywall
- Commercial drop ceilings — Quiet, fast attic-cavity coverage in offices and retail
