Attic Insulation

Stop losing heat through the top of your home. Professional upgrades to R-60, backed by government rebates.

Your Attic Is Your Home's Biggest Heat Loss Point

Up to 40% of a home's heating and cooling energy escapes through an under-insulated attic. Upgrading to a minimum R-60 value, the highest residential standard in Ontario, eliminates that loss and delivers immediate, measurable reductions in your energy bills.

Renova uses a precision blowing machine to achieve perfectly uniform coverage across the entire attic floor, including hard-to-reach corners and around obstructions. Before any insulation is installed, our team air-seals all penetrations, electrical boxes, and duct connections to eliminate drafts at the source.

Every attic insulation project we complete is eligible for rebates through the Canada Greener Homes Grant. We coordinate the required energy audit and submit all paperwork so the process is completely hands-off for you.
