Blown-In Cellulose. Fast, Eco-Friendly, Effective.
Dense-pack and loose-fill cellulose insulation professionally installed in attics, walls, and floors across Worcester County, MA.
About Cellulose
The smart choice for attic and wall insulation.
Blown-in cellulose is made from 85% recycled paper fiber, treated for fire and pest resistance. BCI Insulation uses dense-pack and loose-fill methods to achieve superior thermal coverage in attics, existing wall cavities, and hard-to-reach spaces — often completed in a single day.
Loose-Fill (Attic)
Ideal for open attic floors. Blown in at high volume to achieve R-38 to R-60+ coverage quickly and evenly. Excellent for retrofitting existing homes without major disruption.
Best for: Attic floors · Retrofit projects · Fast installs · High R-value
Dense-Pack (Walls)
Blown into existing wall cavities through small holes in siding or drywall. No major demolition required. Achieves air-seal performance that batts cannot match.
Best for: Existing walls · Minimal disruption · Air sealing · Older homes
