WHY BLOWN-IN INSULATION?
Blown-in insulation is installed using specialized blowing machines that distribute loose-fill insulation material evenly across your attic floor or into enclosed wall cavities. Unlike batts, blown-in insulation conforms to every obstruction — filling around wires, pipes, trusses, and irregular joist spacing.
This seamless coverage eliminates the gaps and compression issues common with batt insulation, delivering better overall thermal performance. All installations meet Ontario Building Code R-Value requirements.
BLOWN-IN PRODUCTS WE INSTALL
Fiberglass Loose-Fill
Machine-blown fiberglass for open attic spaces. Non-combustible, non-settling, and pest-resistant. The most common choice for new construction attics.
Cellulose Blown-In
Recycled paper fibre treated with fire retardant. Dense-pack capability for enclosed cavities and excellent sound absorption properties.
Attic Top-Up
Adding blown-in insulation over existing attic insulation to bring R-Values up to current Ontario Building Code requirements without removing old material.
Dense-Pack Wall Fill
Blown-in insulation injected into enclosed wall cavities for renovation and retrofit projects where walls cannot be opened.
Floor Cavity Fill
Blown-in insulation for floor assemblies over unheated spaces — garages, crawl spaces, and cantilevered overhangs.
Complete Re-Insulation
Full removal of old, damaged, or contaminated attic insulation followed by new blown-in insulation to meet current code.
