More about Wet-Blown Cellulose Insulation

Wet-blown cellulose insulation, sometimes called wet-spray or damp-spray cellulose insulation, is an insulation material typically used in walls, that is applied directly with a blower. Shredded paper fibers, treated with a fire retardant, are blown through a pressurized nozzle that mixes them with water as it blows. Wetting agents or liquid adhesives may sometimes be mixed in with the water to promote further adhesion. These liquid adhesives may vary widely in identity. This CP covers a wet-blown cellulose applied with both water and a liquid adhesive. The insulation is self-supporting once applied, and must air-dry before drywall is hung. Wet-blown cellulose insulation covered in this CP is distinguished from "stabilized" cellulose insulation, which has a dry adhesive (typically starch) as part of the insulation as sold, and less water is used during its application. "Stabilized" cellulose is designed to settle less over time than loose fill and is indicated especially for attic applications but in some cases may also be used in walls. Stabilized cellulose is excluded from this CP.
