Blown-In Insulation in Utah

Looking for blown-in insulation in Utah? Big City Insulation serves homeowners, builders and contractors in St. George, Washington and nearby communities. We install blown-in fiberglass in homes and commercial buildings for both retrofit and new construction projects.

What Is Blown-In Insulation?

“Blown-in” describes how the insulation is installed. We use a special blowing machine to place loose-fill fiberglass into attics, walls and hard-to-reach spaces. The material settles into gaps and around obstructions, which gives you more complete coverage than many traditional methods.

For new construction, we also offer the Blow-In-Blanket System (BIBS). We blow fiberglass behind a netted fabric to create a seamless blanket that fills wall cavities completely, including around outlets and wiring.

Frequently Asked Questions about Blown-In Insulation in Utah

How much does it cost to install blown-in insulation in Utah?

The cost depends on how big the space is, which material you choose, the R-value you need, and whether you’re adding to existing insulation or starting fresh. Contact Big City Insulation for a free estimate tailored to your home or building.

Is blown-in insulation better than batt insulation?

Blown-in insulation fills gaps, corners and spaces around wiring and pipes that batts can miss. That makes it a great choice for attics and hard-to-reach areas. Batts work well in open, standard-sized wall cavities. We can help you choose the best option for your project.

How long does it take to install blown-in insulation?

Most residential attic jobs are finished in a single day. Larger homes, wall applications and commercial projects may take longer.

Can you add blown-in insulation over my existing attic insulation?

Often, yes. If your current insulation is dry, clean and free of mold or pests, we can usually blow new insulation right over it to raise your R-value. If it’s damaged, we’ll recommend removing it first.

What is an attic re-blow?

An attic re-blow tops up or replaces old, settled or underperforming attic insulation with fresh blown-in material. It’s one of the most cost-effective ways to improve comfort and energy efficiency in older homes.

Does blown-in insulation help in Southern Utah’s hot climate?

Yes. Blown-in insulation slows heat transfer from your attic into your living space. This helps keep your home cooler in the summer and reduces how hard your AC has to work.

Is blown-in insulation good for new construction?

Yes. For new builds, we install blown-in fiberglass using the Blow-In-Blanket System (BIBS). It fills wall cavities completely, including around wiring and outlets. Builders and contractors in Utah use it to meet energy codes and build more comfortable, efficient homes.
