Passive fire protection spray foam in Ontario provides critical fire resistance ratings from 1-4 hours for structural steel and building components, with ULC-certified intumescent coatings expanding up to 50 times their original thickness when exposed to temperatures above 200°C. Professional installation costs range from $8-15 per square foot depending on fire rating requirements and substrate conditions, with most Burlington commercial projects requiring 2-hour fire ratings per Ontario Building Code Section 3.2.3.
What is Passive Fire Protection Spray Foam and How Does It Work?
Passive fire protection spray foam is an intumescent coating system that forms a protective char barrier when exposed to fire temperatures. Unlike active fire suppression systems like sprinklers, passive fire protection works automatically without mechanical activation. The coating contains chemical compounds that react to heat by expanding into a thick, insulating foam that protects structural steel from reaching critical failure temperatures of 538°C.
In Ontario, these systems must meet ULC-S101 fire resistance testing standards and provide fire ratings from 30 minutes to 4 hours depending on building occupancy and height requirements. The intumescent spray fireproofing process involves applying multiple coats to achieve the specified dry film thickness, typically ranging from 1.5mm for 1-hour ratings to 6mm for 4-hour ratings.
Burlington industrial facilities, Toronto high-rises, and Hamilton manufacturing plants all rely on passive fire protection to maintain structural integrity during fire events, allowing occupants time to evacuate and firefighters time to respond effectively.
Which Ontario Building Code Requirements Apply to Passive Fire Protection?
The Ontario Building Code mandates specific fire resistance ratings based on building classification, occupancy type, and structural elements. For Burlington commercial buildings over 18 meters in height, structural steel members require minimum 2-hour fire resistance ratings under Section 3.2.3.1. Industrial occupancies in Mississauga and Oakville typically require 1-2 hour ratings depending on fire load and sprinkler protection.
Key code requirements include:
- Assembly occupancies: 1-3 hour fire ratings for primary structural members
- Industrial Group F occupancies: 1-2 hour ratings with specific exemptions for sprinklered buildings
- Residential high-rise buildings: 2-4 hour ratings for load-bearing elements
- Parking structures: 1-2 hour ratings for structural steel components
Professional contractors must ensure fireproofing inspection requirements are met throughout the application process, with third-party verification required for most commercial projects in Ontario.
How Much Does Passive Fire Protection Cost for Burlington Properties?
Passive fire protection costs in Burlington range from $8-15 per square foot for standard intumescent coatings, with total project costs varying based on fire rating requirements, surface preparation needs, and project complexity. A typical 10,000 square foot warehouse fireproofing project costs $80,000-150,000 CAD including materials, labor, and inspection services.
Cost factors include:
- Fire rating duration (1-hour: $8-10/sq ft, 2-hour: $10-12/sq ft, 4-hour: $12-15/sq ft)
- Substrate condition and preparation requirements
- Access challenges and height considerations
- Environmental conditions and cure time requirements
Many Ontario properties benefit from combining passive fire protection with spray foam insulation for metal buildings, achieving both thermal efficiency and fire safety compliance in a coordinated installation approach.
What Are the Benefits of Professional Passive Fire Protection Installation?
Professional passive fire protection installation ensures code compliance, warranty coverage, and optimal performance during fire events. Licensed contractors understand Ontario-specific requirements, proper surface preparation techniques, and environmental conditions that affect coating adhesion and cure rates.
Key benefits include:
- ULC-certified materials and application methods
- Comprehensive warranty coverage (typically 10-15 years)
- Third-party inspection coordination and documentation
- Integration with other building systems and schedules
Professional installation also addresses unique challenges in Ontario’s climate, including temperature and humidity variations that can affect coating performance. Commercial fireproofing projects require experienced contractors who understand the coordination between trades and inspection scheduling.
How Do You Choose the Right Passive Fire Protection Contractor in Ontario?
Selecting qualified passive fire protection contractors requires verifying ULC certification, Ontario licensing, and project-specific experience. Look for contractors who maintain current WSIB coverage, carry minimum $2 million liability insurance, and provide detailed specifications matching your building’s fire rating requirements.
Essential contractor qualifications include:
- ULC-certified fireproofing technicians and supervisors
- Proven experience with similar building types and fire ratings
- Comprehensive warranty programs and ongoing support
- Established relationships with testing agencies and inspectors
Many property owners find value in contractors who offer multiple services, such as fire rated spray foam insulation alongside passive fire protection, ensuring coordinated installation and single-source accountability.

Frequently Asked Questions
How long does passive fire protection spray foam last in Ontario?
Professional passive fire protection coatings last 15-25 years with proper installation and maintenance. Ontario’s climate requires UV-stable formulations for exposed applications, with periodic inspections recommended every 5 years to ensure continued code compliance and performance.
Can passive fire protection be applied over existing coatings?
Passive fire protection can be applied over compatible existing coatings after proper surface preparation and adhesion testing. Most applications require complete removal of incompatible coatings to ensure proper bonding and fire performance, with compatibility testing required per ULC standards.
What fire rating is required for my Burlington commercial building?
Fire rating requirements depend on building height, occupancy classification, and structural design. Most Burlington commercial buildings require 1-2 hour fire ratings for structural steel, while buildings over 18 meters typically require 2-hour minimum ratings per Ontario Building Code Section 3.2.3.
Does passive fire protection qualify for insurance discounts in Ontario?
Many Ontario commercial insurance providers offer premium reductions for buildings with certified passive fire protection systems. Discounts typically range from 5-15% for comprehensive fire protection measures that exceed minimum code requirements, with documentation required for qualification.
