Spray foam insulation is a cutting-edge solution used widely in residential and commercial buildings across Canada. It involves spraying a liquid material that rapidly expands into thick foam, sealing cracks, gaps, and hard-to-reach spaces. This form of insulation is particularly popular in Canada due to its exceptional energy efficiency and ability to handle the country’s extreme weather conditions.
There are two main types of spray foam insulation: open-cell and closed-cell. Open-cell foam is softer, more flexible, and often used in interior walls for sound dampening. Closed-cell spray foam, on the other hand, is denser, more rigid, and provides a higher R-value, making it ideal for exterior applications, basements, roofs, and attics.
The key advantage of spray foam over traditional insulation materials like fiberglass or cellulose is its air-tight seal. This reduces heat loss during Canada’s harsh winters and keeps cool air in during summer, ultimately lowering energy bills and improving indoor comfort.
Spray foam insulation also acts as a moisture barrier, helping prevent mold and mildew growth, and adds structural integrity to buildings thanks to its rigidity.
✅ Superior thermal performance (high R-value)
✅ Effective air and moisture barrier
✅ Reduces heating and cooling costs significantly
✅ Long lifespan with minimal maintenance
✅ Ideal for cold Canadian winters
✅ Helps with sound insulation in noisy areas
✅ Works well in irregularly shaped spaces
Whether you’re renovating an older property or insulating a new build, spray foam insulation offers a modern, durable, and efficient option that many Canadian homeowners are now choosing for long-term value.
Understanding the cost of spray foam insulation in Canada requires looking beyond just the price per square foot. While it’s true that spray foam insulation costs more upfront than traditional materials like fiberglass or cellulose, its long-term energy savings and performance often justify the investment.
Major Factors Affecting Spray Foam Insulation Costs:
💰 Type of Foam: Closed-cell spray foam costs more but offers better insulation (higher R-value).
📏 Project Size: Larger surface areas cost more but can reduce cost per square foot.
🛠️ Labor & Installation: Skilled labor in cities like Toronto may increase project costs.
🧱 Surface Preparation: Removing old insulation or preparing complex surfaces adds to the expense.
🌡️ Desired R-Value: Higher insulation values require thicker foam, increasing material usage.
📍 Location: Costs vary across provinces—expect higher pricing in major cities.
Though spray foam insulation has a higher initial cost, it delivers energy savings of up to 50%, reduces HVAC wear and tear, and boosts home resale value. For Canadian homeowners seeking long-term efficiency, it’s a smart and sustainable choice.
When considering spray foam insulation for your home in Canada, one of the most important decisions is choosing between open-cell and closed-cell spray foam. Each type has distinct characteristics, costs, and benefits, making them suitable for different insulation needs.
Open-cell spray foam is lighter, more flexible, and generally less expensive. It’s ideal for interior applications where soundproofing is desired, such as in walls or ceilings. On the other hand, closed-cell spray foam is denser, water-resistant, and provides a higher R-value per inch, making it perfect for attics, basements, roofs, or areas exposed to moisture or harsh climates.
Key Differences Between Open Cell and Closed Cell Spray Foam:
🧊 Density & Structure:
Open-cell: Light and sponge-like with open air pockets.
Closed-cell: Rigid and dense with sealed cells.
💸 Cost:
Open-cell: Lower cost ($0.75–$1.50 per board foot).
Closed-cell: Higher cost ($1.50–$3 per board foot) due to greater material density.
🌡️ R-Value (Insulation Effectiveness):
Open-cell: ~R-3.5 per inch
Closed-cell: ~R-6 to R-7 per inch
🔇 Soundproofing:
Open-cell: Excellent at absorbing sound.
Closed-cell: Less effective for sound but better for sealing air leaks.
💦 Moisture Resistance:
Open-cell: Not waterproof.
Closed-cell: Acts as a moisture barrier.
🧱 Best Applications:
Open-cell: Interior walls, ceilings.
Closed-cell: Exterior walls, basements, attics, garages.
