INSULATION SUPPLIES IN TORONTO And The GTA

Buying the right insulation comes down to three questions: where it’s going, what R-value you need, and your budget.

Where it’s going. Open attics take blown-in or batts; wall cavities take batts or spray foam insulation; basements and foundations call for rigid foam or Rockwool, which handle moisture better than fiberglass; rim joists and irregular gaps are the strongest case for spray foam.

What R-value you need. In Toronto’s climate, most attics should be insulated to R-50–R-60, above-grade walls to roughly R-22 or better, and basement walls to about R-20. If your house was built before the 1980s and never upgraded, you are almost certainly below these levels.

Your budget. Fiberglass insulation is the most affordable per square foot; Rockwool costs more but adds fire and sound performance; foam insulation — rigid board or two-component spray foam — costs the most but delivers the highest R-value per inch and air-seals as it insulates. Bring your square footage and cavity depth to either yard and we’ll price the options side by side.

For the Toronto area, aim for R-50 to R-60 in the attic, R-22+ in above-grade walls, R-20 for basement walls, and R-31 for exposed floors. Natural Resources Canada reports that space heating alone accounts for about 62% of the energy used in Canadian homes — which is why the attic, the biggest escape route for heated air, is the most cost-efficient place to add insulation first.

Other Areas That Require Insulation

Walls and attics get the attention, but heat and noise leak from smaller spots too: heating and cooling ducts running through unconditioned space should be wrapped; hot-water plumbing pipes benefit from polyethylene pipe insulation; rim joists, garage ceilings under bedrooms, floors over crawl spaces, and attic hatches all deserve coverage. Insulating ducts in particular can noticeably improve the efficiency of a forced-air system, since leaky, uninsulated ducts dump heated air into spaces you’re not living in.

A properly insulated house costs less to run, feels better to live in, and is worth more when you sell. Cutting heat loss lowers energy costs every month, in both heating season and cooling season. Consistent temperatures room to room end the cold-bedroom problem, and dense products like Rockwool add real noise reduction between floors and from the street.

Insulation is also one of the most eco-friendly upgrades a property can get — less energy burned means a smaller carbon footprint — and modern fire-resistant materials add a genuine layer of safety and security to the building envelope. Additionally, upgraded insulation protects the structure itself by keeping wall assemblies drier.
