Blow-In Insulation in Long Beach

What Is Blow-In Insulation

Efficient Loose-Fill Thermal Protection

Blow-in insulation is a loose-fill material—typically cellulose or fiberglass—that is installed using a high-powered blowing machine to reach open attics, wall cavities, and hard-to-access areas. It fills gaps and irregular spaces to reduce conductive and convective heat transfer, helping maintain consistent indoor temperatures year-round.

Belmont Insulation installs premium loose-fill materials to achieve targeted R-values while improving sound control. Cellulose is treated with borates for fire, mold, and pest resistance; fiberglass is non-combustible and moisture-resistant. When combined with air sealing, blow-in insulation delivers significant performance gains without major demolition, making it ideal for retrofits and upgrades.

Comfort, Energy Savings, and Quiet

Expect more even room-to-room temperatures, fewer drafts, and less strain on HVAC equipment. By blanketing the attic floor and wall cavities, blow-in insulation reduces hot spots in summer and cold spots in winter, enhancing overall comfort in living spaces and over garages or additions.

Energy bills typically decrease as heat loss and gain are reduced, with many homes seeing noticeable savings after installation. You’ll also experience a quieter home thanks to the dense, sound-dampening properties of loose-fill materials. Many projects offer a favorable payback period, and the upgrade can contribute to better indoor air quality when paired with air sealing.

From Assessment to Clean, Precise Results

We begin with a thorough evaluation, measuring existing insulation, identifying gaps, and determining the target R-value for your home. Our team can use tools such as thermal imaging to pinpoint heat loss and recommend air sealing strategies that maximize the performance of blow-in insulation.

Preparation is critical: we seal penetrations around wiring, plumbing, and top plates; protect recessed lights where applicable; install baffles to maintain attic ventilation; and set depth markers to verify coverage. These steps reduce air leakage and ensure the installed insulation performs to specification.

Using calibrated blowing equipment, we install loose-fill insulation to the correct depth and density—open-blow in attics and dense-pack in enclosed cavities—to meet coverage chart requirements. Afterward, we clean the workspace, verify depth and R-value, and provide documentation. Our team can also guide you on potential rebates or tax incentives and the maintenance practices that keep your insulation performing for years.
