Blown cellulose insulation. Recycled, fire-resistant, and rebate-eligible.
Made from 83% recycled content and treated with borate for fire and pest resistance, cellulose fills the gaps and crevices that batts miss. Energize CT rebates of $2.00 per square foot can cover 75-100% of your project costs for Eversource and United Illuminating customers.
The retrofit insulation that fills what batts miss
Blown cellulose is made from 83% recycled newsprint, treated with borate for fire resistance, mold deterrence, and pest protection. It fills gaps and irregular cavities that batts leave behind, making it the go-to material for retrofits — without major demolition. Energize CT rebates of $2.00 per square foot can cover 75–100% of approved project costs for Eversource and United Illuminating customers.
-
Less expensive than spray foam — competitive pricing with better air sealing than batts
-
Ideal for retrofits — blown through small access holes, no major demolition needed
-
Rebate-eligible through Energize CT — $2.00 per square foot, covering 75-100% of costs

What it is
How cellulose performs once it is in your walls and attic
Cellulose is built from about 83 percent recycled content
One of the greenest insulating materials made. Blown cellulose is produced mostly from recycled newsprint, treated with borate to resist fire, mold, and insects, and finished with a small amount of mineral oil to bond the retardant and keep dust down — manufacturing it consumes far less energy than other common insulating materials, which is part of why it qualifies well for Connecticut's weatherization incentives.
- About 83% recycled newsprint content — among the lowest manufacturing footprints
- Borate treatment: fire-resistant, mold-deterrent, and insect-repellent
- Qualifies well for Connecticut's weatherization incentive programs
It resists fire, quiets rooms, and manages moisture
The borate treatment adds multiple layers of protection. Cellulose slows flame spread and produces minimal smoke; its high Sound Transmission Class and Noise Reduction Coefficient ratings noticeably dampen noise between floors and from outside; and being hygroscopic, it absorbs and releases small amounts of moisture without losing insulating value — a trait that helps it hold up in Connecticut retrofits where airtight detailing is hard to achieve.
- Borate treatment slows flame spread and produces minimal smoke
- High STC and NRC ratings reduce noise between floors and from outside
- Hygroscopic: absorbs and releases moisture without losing insulating value
What cellulose insulation does for your home
Cellulose fills gaps and crevices that batts miss, creating a tighter thermal envelope. Connecticut families report more consistent room-to-room temperatures in winter and summer after a blown-cellulose retrofit.
High STC and NRC ratings make cellulose one of the strongest insulation materials for reducing noise between floors and from outside traffic — benefits that batts and rigid board rarely match.
Made from 83% recycled newsprint and treated with borate, cellulose is stable, pest-resistant, and fire-resistant. Once installed correctly it needs no maintenance and keeps performing for the life of the home.
5 steps to a new system you can count on
Every installation follows the same proven process — whatever equipment you're upgrading — from your first call through years of reliable service.
