Code-Compliant Commercial Spray Foam Insulation in Ontario
Commercial spray foam insulation must meet performance and safety requirements specific to building type, occupancy, and use. Our installations are completed in accordance with applicable Ontario Building Code standards and manufacturer specifications, helping ensure long-term performance, proper air sealing, and compatibility with commercial construction systems.
We regularly work alongside general contractors, property managers, and facility teams to ensure spray foam insulation integrates cleanly with mechanical, electrical, and fire-rated assemblies. This approach helps support inspections, reduce rework, and keep commercial projects moving on schedule.
Why Choose Commercial Spray Foam Toronto Insulation?
Commercial buildings require insulation systems that perform reliably at scale. Spray foam insulation provides both air sealing and thermal resistance in a single application, making it a practical solution for offices, warehouses, retail spaces, and industrial facilities throughout Toronto and Ontario.
- Continuous air barrier to reduce energy loss and drafts
- Helps control moisture and condensation in large spaces
- Suitable for complex framing and irregular surfaces
- Long-term durability with minimal maintenance
- Installed efficiently to align with commercial construction schedules
How Commercial Spray Foam Works
Commercial spray foam insulation is applied directly to building surfaces where it expands and cures into a seamless insulation and air barrier. This process allows large commercial spaces to be insulated efficiently while addressing air leakage, thermal performance, and moisture control in a single system.
1. Site Review & Scope Confirmation
We begin by reviewing site conditions, building use, and insulation requirements to ensure spray foam is applied in the correct areas and thicknesses for the project.
2. Surface Preparation
Substrates are prepared to ensure proper adhesion. This step is critical for consistent coverage and long-term performance in commercial environments.
3. Spray Foam Application
Spray foam is applied evenly to walls, ceilings, or roof decks, expanding to seal gaps and create a continuous thermal barrier. This method is especially effective for large or irregular commercial spaces.
4. Integration With Other Building Systems
On many projects, commercial spray foam insulation is coordinated alongside related services such as fireproofing services to ensure compatibility with structural and safety requirements.

Open-Cell vs Closed-Cell Spray Foam
In commercial and industrial buildings, the choice between open-cell and closed-cell spray foam depends on factors such as moisture exposure, structural requirements, and overall building performance goals.
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
Commercial spray foam insulation pricing varies based on building size, insulation thickness, access conditions, and project complexity, with costs typically assessed after a site review.
- 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.
Spray Foam Insulation FAQs
Is spray foam insulation suitable for commercial buildings?
Yes. Spray foam insulation is widely used in commercial and industrial buildings to improve energy efficiency, reduce air leakage, and help control moisture in large-scale spaces such as warehouses, offices, and retail facilities.
Can commercial spray foam be installed during renovations or retrofits?
Yes. Commercial spray foam insulation is commonly installed during renovations, tenant improvements, and retrofits, as well as new construction projects, provided site conditions allow for proper application.
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.
