Cellulose Insulation
A versatile blown-in insulation option suitable for attics, wall cavities and a variety of new-construction or retrofit projects throughout Southwestern Ontario.
What is Cellulose?
Dense, Recycled & Sound-Dampening
Cellulose insulation is manufactured from recycled paper fibres treated with fire retardants. It is blown into attics and dense-packed into wall cavities, conforming around wires, pipes and irregular framing to eliminate voids and air gaps.
Its higher density gives cellulose strong thermal performance and genuine sound-control potential—ideal for shops, livestock facilities, and homes where noise and temperature control both matter.
- Coverage around irregular spaces
- High thermal performance
- Suitable for existing and new structures
- Efficient blown-in installation
- Sound-control potential
- Made from recycled paper content
Common Applications
Attic Top-Ups
Add depth over existing insulation to boost R-value.
Enclosed Wall Cavities
Dense-pack cellulose into retrofit wall assemblies.
New Construction
Blown into newly framed ceilings before drywall.
Agricultural Shops
Insulate farm shop ceilings and storage buildings.
