The Affordable Attic Fix
Blown-in insulation is often the best value for a vented attic with an open floor. Loose cellulose or fiberglass is blown through a hose to fill around joists, wiring and pipes. HomeGuide lists blown-in at about $1.00 to $2.80 per square foot, and $900 to $3,600 for a typical attic.
Seal before you blow
Blown-in slows heat but does not stop air. We seal the gaps in the attic floor first, so the new insulation is not just filtering leaky air.
How deep
Georgia's code lists R-38 for ceilings. The Department of Energy suggests R-49 to R-60 in an empty Zone 3 attic, or R-38 to R-49 added over 3 to 4 inches. HomeGuide lists cellulose at R-3.1 to R-3.8 per inch and loose fiberglass at R-2.2 to R-2.9, so those targets take a foot or more of material. We install to the settled depth on the bag chart and place depth markers.
Cellulose or fiberglass
Cellulose packs denser and resists air movement better. Fiberglass is lighter and does not absorb water. Both work in a vented attic, and we recommend one for your house.
Enclosed cavities
Blown-in also works for enclosed spaces like floors under bonus rooms and closed walls (dense-pack). Get a free estimate

Blown-In Insulation Questions
Cellulose or fiberglass for a Georgia attic?
Both work. Cellulose resists air movement better, fiberglass handles moisture better. We suggest one and can price both.
How long does blown-in take?
Most attics are done in a day.
Will blown-in settle?
Slightly. We install to the settled depth for your target R-value.
Can blown-in go over old insulation?
Yes, if the old insulation is dry and clean.
