5 Common Questions About Spray Foam & Batt Insulation in Toronto, Aurora & Newmarket

Insulating your home can be confusing — many ask which product works best, when to install it, and how much it costs. Here are the top questions answered by our experts.

1. Which is better — spray foam or batt insulation?

Each has its place. Spray foam creates an airtight seal and higher R‑value per inch (great for exterior walls, basements, and attics). Batt insulation is cost‑effective for interior walls and ceilings.

Most modern Ontario homes use a hybrid system — and we’re certified to install both.

2. How much does insulation installation cost in the GTA?

Costs vary by type and thickness:

- Spray foam: $3 – $5 per sq. ft.

- Fiberglass or mineral batt: $1.50 – $2.50 per sq. ft.
