The short version

Loose-fill insulation blown into attics and walls for even coverage with no gaps.

Blown-in insulation fills every cavity and crack in a way batts cannot. For most Iowa attics, it is the cheapest and fastest way to bring R-value up to modern code. 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 blown-in 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 blown-in insulation job covers this.

01

Attic blow to R-49

Iowa code for attic insulation is R-49 (roughly 14-16 inches of cellulose or 18+ inches of fiberglass). We measure current depth, blow to code or above.

02

Cellulose or fiberglass

Cellulose settles denser and offers slightly better air-seal performance. Fiberglass is lighter and doesn’t settle. We recommend based on your attic and climate zone.

03

Baffles at eaves

Eave baffles keep insulation from blocking soffit ventilation. Without them, the attic can’t breathe and insulation traps moisture.

04

Air-seal first

Blowing insulation over unsealed penetrations wastes money. We air-seal top plates, recessed lights, plumbing, and wiring chases before insulating.

05

Depth markers installed

Visible depth markers left in the attic so future inspections can verify coverage without tape-measuring.

06

Clean install

Plastic down, work area contained, vacuumed afterward. No residual insulation in your garage or living space.

Blown-In Insulation · FAQ

Questions we hear about blown-in insulation.

What R-value should my attic have?

Iowa (climate zone 5) code calls for R-49 in attics, which is roughly 14-16 inches of cellulose or 18+ inches of fiberglass. Older homes often sit at R-19 to R-30. Bringing to R-49 is one of the highest-ROI efficiency upgrades you can make.

Cellulose or fiberglass, which is better?

Cellulose is denser, better at slowing air movement through the attic, and made from recycled paper. Fiberglass is lighter, doesn’t settle over time, and doesn’t absorb water. For most attics we lean cellulose. Some homes (especially with moisture concerns) get fiberglass.

Do I need to air-seal first?

Yes, if you want the insulation to actually perform. Air leakage through unsealed penetrations can destroy the R-value of the insulation above it. We air-seal as part of every blown-in install.

How long does it take?

Most attic blows are a half-day to full day for a typical Iowa home. 2-person crew, minimal disruption to your living space.

Will it help my heating bill?

Yes, measurably. A home going from R-19 to R-49 attic insulation typically sees 15-25% heating cost reduction. Exact savings depend on your home, HVAC, and habits. We can provide blower-door test data before and after if you want hard numbers.
