CleanFiber Cellulose Insulation is a cellulose insulation for attics, walls, and floors in residential or commercial new construction and retrofit applications. The dense cellulose stops airflow and fills cavities tightly, reducing heat leaks and HVAC runtime. It supports envelope upgrades and improves overall thermal performance. By eliminating drafts and reducing thermal bridging, occupants experience more stable temperatures and improved comfort.

- Made from recycled corrugated cardboard, - Patented wet/liquid process embeds fire retardant into fibers, - Lower free-chemical loadings than dry-process alternatives, - Less corrosive and avoids ammonia odors or moisture-related corrosion issues, - Cleaner, more uniform fibers improve flowability and coverage, - Smooth installation with fewer clogs and delays, - Low dust and contamination during installation, - Compatible with multiple installation methods (dense-pack, loose-fill, wet-spray), - Provides strong thermal insulation (supports indoor temperature regulation), - Improves acoustic performance compared to fiberglass, - Supports lower embodied carbon in low-carbon building assemblies, - Competitively priced relative to blended or conventional cellulose insulation

reduce building energy/utility costs, upgrade your building envelope, insulate your building / unit, regulate indoor temperature

O&M-related savings: customers report saving time and money when accounting for equipment clogging and dust issues

- Reduces building carbon both by improving energy efficiency through better insulation and air control, and by using recycled, biogenic feedstock that stores carbon; - Enables substantial embodied-carbon savings when paired with low-carbon structural systems.

The insulation is carbon negative and acts as a carbon sink by storing natural carbon in buildings.
