Walls
Why Cellulose
Built for full-cavity coverage
Greenfiber® insulation is a smart solution for walls, with flexible installation methods including loose-fill, dense-pack and spray-applied applications. It fills wall cavities to form a continuous, monolithic blanket that significantly reduces heat transfer, sound and air movement.
Spray-Applied
Spray-Applied
Open Wall Cavities
Spray-applied cellulose insulation is sprayed into open wall cavities using a fine water mist, filling gaps for a perfect fit and superior resistance to air infiltration. It adheres to studs, reduces sound and is ideal for new construction before drywall. Allow 24 hours of drying time.1

Behind Netting
Open Wall Cavities
Dense-pack cellulose is installed dry at high density behind netting, filling cavities completely to form a seamless, monolithic blanket. This prevents settling, boosts energy efficiency, reduces drafts, and provides cost-effective noise control and thermal comfort.

Drill & Fill
Existing or Closed Wall Cavities
Drill-and-fill retrofits enclosed walls by dense-packing cellulose insulation under pressure through small exterior holes. This cost-efficient method improves energy performance, controls air and moisture, and installs dry with no delays.
