Maximizing Home Energy Efficiency with Spray Foam Insulation in Ontario: A Comprehensive Guide for 2024

Are you looking for an effective solution to a moldy basement or drafty attic? Adding attic or basement insulation in Toronto will help you save money on energy bills. Also, in 2023, it could qualify you for a rebate through the Canada Greener Homes Grant.


Read on to learn more about what spray foam insulation is, why it is a cost-effective solution for your home, and how to choose the best insulation company in Toronto.

What Is Spray Foam Insulation?

Unlike traditional insulation materials, spray foam doesn't merely cover surfaces but expands to fill every nook and cranny. Thus, it creates an impermeable barrier against drafts and moisture.


Two primary types of spray foam insulation are closed-cell foam and open-cell foam. Open-cell foam is characterized by its structure. It is filled with cells deliberately left open. This results in a softer and more flexible material.


In contrast, closed-cell foam consists of cells that are tightly pressed together, forming a dense and rigid structure. The closed nature of the cells prevents air and moisture infiltration, making closed-cell foam an excellent choice for areas requiring superior waterproofing and structural stability.


While open-cell foam offers flexibility and cost-effectiveness, closed-cell foam provides enhanced durability and superior insulation.

Spray Foam Insulation and Canada Greener Homes Grant

The Home Efficiency Rebate Plus program, conducted in partnership with the Canada Greener Homes Grant, has achieved remarkable success in Ontario. Enbridge Gas, in collaboration with the Canada Greener Homes Grant, has assisted over 100,000 households in the province to lower their energy usage and carbon footprint. Due to overwhelming demand and the participation of numerous households, all available spots funded jointly by Enbridge Gas and the Canada Greener Homes Grant have been filled earlier than anticipated. As of the end of the day on Monday, Feb. 5, 2024, no new applications are accepted, nor will any pre-retrofit energy assessments be processed beyond this date for inclusion in the program.


We wanted to tell you about this opportunity because it testifies to the excellence of spray foam insulation. According to our government, poorly insulated walls can account for about 20 percent of heat loss in residential homes. Spray foam insulation was among one of the upgrades that Ontario homeowners could get rebates for.


Even though the program is now over, upgrading your attic or basement insulation to spray foam insulation is still worth it as it will help you save on your energy bills.

Home Energy Loan Program

Another excellent opportunity to get your foam insulation costs reimbursed is through the Home Energy Loan Program (HELP) in Toronto. You could borrow up to $125,000 to cover the cost of home energy improvements, including attic insulation, basement insulation, and exterior wall insulation in Toronto.

How to Choose the Right Insulation Company in Toronto

First, make sure that the insulation company is licensed and insured and meets all the installation requirements of the Canadian National Building Code and the spray foam manufacturer. The use of 2lb. Closed Cell MD SPF is covered by two CAN/ULC Standards:

  • CAN/ULC S705.1 for Material Conformity
  • CAN/ULC S705.2 for the Installation Standard


Furthermore, request detailed quotes from multiple companies to make an informed decision. Lastly, don't hesitate to ask questions about the insulation company's experience and any guarantees or post-installation support they provide.
