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
Dense-Pack
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.
