Blown-In Insulation in Salt Lake City
Loose-fill cellulose, fiberglass, or rockwool blown to modern R-values for Utah attics. Air sealing first, then coverage — most jobs done in a day.
Heating and cooling account for 50% to 70% of the energy used in the average American home (U.S. Department of Energy), and in most houses the attic is where the biggest share of that conditioned air escapes. Blown-in insulation is the workhorse fix: loose-fill material distributed evenly across the attic floor to the depth your home actually needs.
Materials: cellulose, fiberglass, or rockwool
We install three loose-fill materials and match the material to the house rather than selling one brand:
- Cellulose — recycled paper treated for bug and fire resistance. Dense, fills irregular framing well.
- Fiberglass — spun from recycled glass and molten sand. Light and consistent.
- Rockwool (mineral wool) — made from volcanic rock and slag. More fire- and water-resistant, and better at reducing noise.
Most of Utah requires attics insulated to R-49 to R-60. Many existing attics were built to a fraction of that, so we measure what you have and quote the depth needed to close the gap.
Air sealing comes first
Regardless of which material you choose, without proper air sealing you will not achieve the insulation's intended R-value. Before we blow anything, we seal the penetrations in the ceiling plane — light fixtures, fan housings, vents, and chases — so the new insulation performs at the number on the bag.
Timeline and cleanup
Job length varies with the size of the home and the extent of the work, but the majority of jobs are completed in a day, typically under 8 hours. Hoses run through a window or door, floors are protected, and we clean up before we leave.
