The short version

Dense blown cellulose, made from recycled paper. Best air-sealing blown option.

Cellulose insulation is dense, settles tightly into every cavity, and slows air leakage better than fiberglass. For most Iowa attics, it is our first recommendation. We do this work across Dallas, Polk, Boone, and Story counties on homes that range from 100-year historics to last-year new construction. Every job starts with the same walkthrough, estimate, and written scope.

The cellulose insulation work we do is not a sub-contractor arrangement. Christian runs it, his crew installs it, and the invoice has one name on it. That matters for warranty claims, for callback response, and for accountability when something needs attention after the job closes.

What’s included

Every cellulose insulation job covers this.

01

Dense-pack attic install

Blown cellulose to R-49 or above. Fills around wiring, joists, and irregular spaces where batts would gap.

02

Wall cavity dense-pack

Blown into existing wall cavities through drilled access holes. Patched and primed. Dramatic efficiency improvement on older uninsulated homes.

03

Borate fire treatment

All cellulose is treated with borate for fire resistance, mold resistance, and insect resistance. Same borate used in home pest treatments.

04

Settled weight calculations

Cellulose settles 20% after install. We blow to the correct inches so final depth hits the R-value spec, not the initial height.

05

Recycled paper content

Cellulose is ~80% post-consumer recycled newsprint. One of the lowest embodied-energy insulation options on the market.

06

Compatibility with other systems

Cellulose works with fiberglass batts below, foam board at the top plate, and spray foam at air-seal points. We design hybrid systems when the attic calls for it.

Cellulose Insulation · FAQ

Questions we hear about cellulose insulation.

Why cellulose over fiberglass?

Denser, better at slowing air movement, and made from recycled material. The tradeoff is weight (can be too heavy for weak ceilings) and moisture sensitivity (fine in dry attics, avoid near leaks).

Is cellulose flammable?

No. Borate treatment makes cellulose self-extinguishing. It carries a Class A fire rating, same as drywall. Many fire tests show cellulose performing better than fiberglass at slowing flame spread in a wall assembly.

Does cellulose attract pests?

No, the borate treatment actively repels insects. Borate is the same compound used in commercial pest treatments.

Will cellulose settle?

Yes, about 20% from initial blow to final depth. Quality installers account for this and blow to a deeper initial height. We do. Measure final depth at 6 months and you should be at spec.

Can I dense-pack my walls without tearing them open?

Usually yes. We drill access holes through the siding or interior drywall (your choice), blow the cellulose in at high density, patch the holes, and prime. A day or two of work and your walls go from R-0 or R-11 to R-13+ effective.
