How Fireproofing Works
Fireproofing is a specialized process designed to protect structural elements by slowing heat transfer and helping maintain structural integrity during a fire. In commercial and industrial buildings, fireproofing toronto is typically applied to exposed steel, concrete decks, and other critical assemblies to meet project requirements and support fire-resistance ratings.
Depending on the application, fireproofing materials are either spray-applied, board-based, or intumescent, each chosen based on fire rating needs, environment, and inspection requirements.
- Applied to steel beams, columns, and decks
- Expands or insulates when exposed to heat
- Slows structural failure during fire events
- Helps achieve required hourly fire ratings
- Installed before final finishes and inspections
Review site conditions and project requirements, including coordination with other building systems such as spray foam insulation services

Open-Cell vs Closed-Cell Spray Foam
While fireproofing is designed to help protect structural elements during a fire, spray foam insulation focuses on energy efficiency, air sealing, and moisture control in residential and commercial buildings.
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
Where We Install Spray Foam Insulation
These insulation areas are often addressed alongside fireproofing work on commercial and mixed-use projects, helping ensure both energy performance and structural protection are considered during construction or renovation.
Ideal for reducing heat loss, improving comfort, and increasing energy efficiency in homes.
Helps control moisture, air leaks, and temperature fluctuations in below-grade spaces.
Seals one of the most common sources of air leakage in residential homes.
Improves comfort and insulation performance in attached garages and home additions.
Designed for offices, retail spaces, warehouses, and commercial buildings.
Custom spray foam solutions for specialized and industrial insulation needs.
Spray Foam Insulation Pricing Factors
While this section outlines pricing considerations for spray foam insulation, fireproofing project costs are typically based on material type, coverage requirements, and site conditions specific to commercial and industrial buildings.
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.
Fireproofing Toronto FAQs
What types of buildings require fireproofing in Ontario?
Fireproofing is commonly required in commercial and industrial buildings such as warehouses, parking garages, office buildings, multi-unit residential properties, and manufacturing facilities. Requirements depend on building use, construction type, and applicable code or project specifications.
Is fireproofing the same as spray foam insulation?
No. Fireproofing is designed to help protect structural elements by slowing heat transfer during a fire, while spray foam insulation is used for energy efficiency, air sealing, and moisture control. Some projects require both services, but they serve different purposes.
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.
