Cellulose Insulation Guide

Recycled paper fiber, treated for fire and pests, installed loose or dense-packed. Here is where it shines.

Cellulose is made mostly from recycled paper, shredded and treated with borate to resist fire, mold and pests. It is blown into attics as loose-fill and packed into walls at higher density. It conforms to odd shapes and fills gaps around wiring and framing better than batts.

Its density slows air movement, which helps comfort, and its recycled content appeals to many owners. It does not do well when soaked, so a dry attic or wall is important, and the installation needs careful depth and density control.

Best for

  • Closed walls in older homes
  • Attics with obstructions
  • Owners who value recycled content
  • Projects needing air resistance and sound dampening

How we handle it

  • Fills gaps and irregular cavities
  • Dense fill slows air movement
  • Recycled content
  • Sound dampening

Keep in mind

  • Slow to dry if it gets wet
  • Dusty to install
  • Settles in loose-fill form
  • Needs careful density control
The details

Fills irregular spaces

Wraps around wires and framing.

Questions

Cellulose FAQ

Is cellulose better than fiberglass?

It resists air movement more and fills better in irregular spaces. Fiberglass resists moisture better.

Does cellulose settle?

Loose-fill settles somewhat, and dense-pack resists it. We install to specified densities.

Is cellulose fire resistant?

It is treated to slow flame spread. It is not fireproof, and rules for clearance around flues still apply.
