What Is Blown-In Insulation?
Blown-in insulation uses specialized equipment to fill attics, walls, and enclosed cavities with loose-fill material — either cellulose (recycled paper treated with fire retardant) or fiberglass. The material is pneumatically blown into place, conforming to irregular shapes and filling voids that pre-cut batts can't reach.
Cellulose
Made from recycled newsprint treated with borate fire retardants. Cellulose has excellent thermal performance (R-3.2 to R-3.8 per inch), good sound dampening, and is one of the most environmentally friendly insulation options available. It's dense enough to resist air movement through the material.
Fiberglass Loose-Fill
Blown fiberglass is lightweight, non-combustible, and won't absorb moisture. It provides R-2.2 to R-2.7 per inch and is ideal for attic applications where depth isn't a constraint. It's also an excellent choice for dense-packing enclosed wall cavities.
Benefits
- Seamless coverage: Fills around wires, pipes, and framing members
- Fast installation: Most attics completed in a single day
- Cost-effective: Lower material cost than spray foam with excellent performance
- Retrofit-friendly: Can be added over existing insulation to boost R-value
- Minimal disruption: No demolition needed for wall cavities
