Blown-In Insulation in Dover, OH

Blown-in insulation is loose cellulose or fiberglass delivered through a hose. It fills around joists, wires and pipes, and it can be packed into closed wall cavities through small holes. For a large open attic floor, it is usually the least expensive way to reach the R-49 that Ohio's code lists for Zone 5A ceilings, or the R-60 ENERGY STAR suggests for empty attics.

In attics

After sealing the attic floor, we blow insulation to a measured depth and leave depth markers so you can check it. Baffles at the eaves keep soffit vents clear.

In walls

Many pre-1940 homes in Dover and the canal towns have walls with nothing in them. We drill small holes, usually from outside under the siding, and dense-pack cellulose into each bay. Dense-packed cellulose slows air movement as well as heat. Holes are plugged and siding replaced.

Cellulose or fiberglass

Cellulose is made largely from recycled paper treated for fire resistance; it packs densely and resists air movement in walls. Blown fiberglass is lighter and does not settle as much in attics. Fixr's figures put fiberglass at $1.65 to $2.60 and cellulose at $1.75 to $3.80 per square foot; we recommend one or the other based on the space.

Before blowing walls

We check for live knob-and-tube wiring, which should not be buried, and for moisture problems in siding or gutters.
