Code-Compliant Garage Insulation in Ontario
Garage insulation plays an important role in maintaining energy efficiency and comfort, particularly in homes with attached garages or living space above the garage. Our garage insulation installations are completed in accordance with applicable Ontario Building Code requirements and manufacturer guidelines to help ensure proper thermal performance and compatibility with surrounding building assemblies.
Whether insulating garage walls, ceilings, or shared walls between the garage and living areas, we assess conditions carefully to ensure insulation solutions help reduce heat loss, limit drafts, and support long-term durability.
Why Choose Garage Insulation in Toronto?
In Toronto’s climate, uninsulated garages are a common source of cold air, drafts, and heat loss—especially in homes with attached garages or living spaces above. Proper garage insulation helps reduce temperature swings, improve comfort inside the home, and limit heat transfer from unconditioned spaces.
Insulating the garage can make a noticeable difference in rooms next to or above the garage, particularly during cold winters and seasonal temperature changes.
- Helps reduce cold air entering the home from the garage
- Improves comfort in rooms above or beside the garage
- Reduces drafts and temperature fluctuations
- Supports better overall energy efficiency
- Installed efficiently with minimal disruption
How Garage Insulation Works
Garage insulation works by slowing heat transfer between unconditioned garage spaces and the rest of the home. Proper insulation helps reduce cold air infiltration, stabilize temperatures, and improve comfort in rooms connected to or located above the garage.
Because garages often share walls or ceilings with living areas, insulation solutions are selected and installed to perform reliably without interfering with daily use of the space.
1. Garage Assessment
We begin by evaluating garage walls, ceilings, shared surfaces, and existing insulation to determine where heat loss and drafts are most likely occurring.
2. Preparation & Air Sealing
Before insulation is installed, gaps, seams, and penetrations are addressed to help reduce air leakage. In many garages, this work is completed using spray foam insulation services in Toronto for targeted air sealing.
3. Insulation Installation
Insulation is installed on garage walls, ceilings, or shared surfaces as needed to achieve consistent coverage and proper thermal resistance.
4. Final Check
Once installation is complete, insulation placement and coverage are reviewed to ensure performance goals are met.

Open-Cell vs Closed-Cell Spray Foam
In garage insulation projects, spray foam is commonly used where air sealing and thermal performance are especially important, such as shared walls and ceilings connected to living spaces.
Open-Cell Spray Foam
Open-cell spray foam is a lighter, more flexible insulation that expands to fill wall cavities and irregular spaces. It provides excellent air sealing and sound reduction, making it a popular choice for interior walls, attics, and residential applications where breathability is important.
- Expands easily into wall cavities
- Excellent air sealing and sound reduction
- More flexible and breathable material
- Commonly used in attics and interior walls
Closed-Cell Spray Foam
Closed-cell spray foam is a dense, rigid insulation with a higher R-value per inch. It adds structural strength, resists moisture, and creates a strong vapour barrier, making it ideal for basements, crawl spaces, rim joists, and commercial or industrial buildings.
- Higher R-value per inch
- Acts as a moisture and vapour barrier
- Adds strength to walls and structures
- Ideal for basements, rim joists, and commercial buildings

Spray Foam Insulation Pricing Factors
Garage insulation pricing depends on factors such as garage size, attachment to the home, access conditions, and the insulation method required to achieve proper performance.
Spray foam insulation pricing can vary depending on the scope of the project and the conditions of the space. Rather than using flat pricing, we assess each job individually to ensure accurate estimates and long-term performance.
- Area being insulated (attic, basement, rim joist, garage, or commercial space)
- Total square footage of the project
- Type of spray foam used (open-cell or closed-cell)
- Accessibility and condition of the space
- Residential vs commercial application
As a general reference, spray foam insulation projects in Toronto and across Ontario typically range from a few thousand dollars for smaller residential areas to higher costs for larger homes or commercial buildings. Final pricing depends on site conditions, insulation type, and project scope, which is why we provide custom estimates after an on-site assessment.
GARAGE INSULATION — FAQ SECTION
Does insulating a garage help rooms above stay warmer?
Yes. Properly insulating garage ceilings and shared walls helps reduce heat loss, making rooms above or beside the garage more comfortable—especially during Toronto winters.
Can both attached and detached garages be insulated?
Yes. Garage insulation can be installed in both attached and detached garages, depending on how the space is used and how it connects to the rest of the home.
How much does spray foam insulation cost per square foot in Toronto?
Most quotes depend on foam type, thickness, and access. As a general Toronto reference, professional installation is often cited in the range of about $1.50 to $4.90 per sq ft (varies by project and specs). The fastest way to get an accurate number is an on-site assessment.
How much does it cost to spray foam 1000 sq ft in Toronto / GTA?
For a 1,000 sq ft project in the Toronto area, you’ll commonly see totals in the $2,500 to $6,000 range depending on thickness, open vs closed-cell, and prep work. Exact pricing changes based on how many inches you need and what surfaces are being sprayed.
How much does it cost to spray foam a 24x24 garage?
A 24’ x 24’ (2-car) garage is commonly estimated around $3,000 to $8,000, with many examples citing an average near $6,000 when walls + ceiling + labor are included. Final cost depends on whether it’s attached, the coverage areas, and required R-value.
How much does 2 inches of spray foam cost?
Spray foam is often priced by the board foot (1 sq ft × 1 inch thick). At 2 inches, you’re using 2 board feet per sq ft. Published Canadian ranges often show roughly $0.50–$1.00/board foot (open-cell) and $1.25–$1.65/board foot (closed-cell) as reference pricing points—then installation, prep, and access affect your final installed rate.
Is open-cell or closed-cell spray foam more expensive?
Closed-cell is typically more expensive because it’s denser and delivers a higher R-value per inch. Common published references show open-cell around $0.50–$1.00/board foot and closed-cell around $1.25–$1.65/board foot, with installed project totals varying by thickness and scope.
What factors affect spray foam insulation pricing?
Pricing usually depends on:
Area type (attic, basement, rim joist, garage, commercial)
Square footage + thickness (inches / R-value)
Open-cell vs closed-cell
Access & prep work (old insulation removal, tight areas)
Residential vs commercial requirements
How thick should spray foam insulation be in Ontario?
Thickness depends on where it’s installed and target performance. Published guidance often suggests roughly 5–6 inches for open-cell or 3–4 inches for closed-cell for many Canadian climates, with adjustments based on code and building design. We confirm the right build-up during the estimate.
Are there rebates for insulation upgrades in Ontario?
Some Ontario homeowners may qualify for utility rebate programs (availability and eligibility vary). For example, Enbridge promotes home efficiency rebates that can apply to insulation/air sealing in certain cases.
