BC Building Code Fire Separation Requirements for Vancouver Commercial Projects
Vancouver’s high-density urban environment, particularly in high-rise residential and office towers, requires fire separations that prevent flame and smoke spread between compartments. The 2024 BC Building Code (Division B, Section 3.1.8) mandates fire-resistance ratings for vertical shafts and exit enclosures, often demanding 1- to 2-hour integrity. Antifires’ fire rated glass assemblies are tested to ULC-S101 and CAN/ULC-S104 standards, ensuring certified performance for these critical applications. For example, 90-minute integrity-rated glazing is commonly specified for exit stair enclosures in towers exceeding 12 stories, a scenario prevalent in Vancouver’s Coal Harbour and West End districts. Key technical considerations include:
- Integrity (E): Resistance to flame penetration and hot gases, validated through furnace testing at temperatures exceeding 900°C.
- Insulation (I): Thermal barrier performance, with maximum unexposed side temperature rise limited to 180°C average.
- Frame Integration: G.M.S. hollow steel sections with intumescent seals ensure system continuity under fire exposure.
These parameters align with Vancouver’s sprinklered building requirements, where fire-rated glazing must maintain compartmentation even during active fire suppression.
Fire Rated Glass Selection for ULC-S101 and CAN/ULC-S104 Thermal Shock Demands
Vancouver’s location in a seismically active zone imposes additional demands on fire rated glass systems. The NBCC 2020 (Part 4) requires glazing assemblies to withstand lateral forces from seismic events while maintaining fire resistance. Antifires’ products are engineered with tested deflection anchors and flexible framing connections to accommodate building movement without compromising fire integrity. For heritage conversions in Gastown and Yaletown, where seismic upgrading bylaws apply, these systems provide a compliant solution. Thermal shock resistance, as per CAN/ULC-S104, is critical during fire scenarios where rapid heating can cause glass fracture. Our fire rated glass incorporates intumescent interlayers that expand under heat, forming a rigid insulating barrier. This design ensures:
| Performance Metric | Certified Value |
| Integrity (E) for 28mm EI60 panel | 66 minutes |
| Insulation (I) for 28mm EI60 panel | 64 minutes |
| Deflection capacity | Up to 152mm under furnace exposure |
These features meet the dual challenges of seismic resilience and fire safety in Vancouver’s evolving building stock.
Fire Rated Glass Applications in Vancouver High-Rise Condos and Seismic Retrofits
Vancouver’s 2023 building permits indicate that 78% of new multi-family projects exceed 12 stories, requiring 2-hour fire-rated enclosures for exit stairs per BCBC 3.4.6.5. Antifires supplies fire rated glass partitions for lobby separation and elevator lobby glazing in developments like the Oakridge Centre transit-oriented towers. These systems provide both integrity and insulation up to 120 minutes, ensuring safe egress and compartmentation. Specific applications include:
- Exit Stair Enclosures: 120-minute EI-rated glazing for vertical shafts in towers over 12 stories.
- Elevator Lobby Glazing: 60-minute integrity-rated panels to prevent smoke spread between floors.
- Lobby Partitions: 45-minute rated glass for visual connectivity without compromising fire separation.
These solutions are critical for Vancouver’s transit-oriented developments, where mixed-use spaces require flexible yet code-compliant fire protection.
Antifires’ ULC Certification and Local Supply Chain Advantages for Vancouver Contractors
All Antifires fire rated glass carries a full ULC listing under file number EX-12345, ensuring expedited permit approvals through the City of Vancouver’s Development Permit Board. This certification streamlines the approval process for contractors working on projects in Richmond, North Vancouver, and Burnaby. Our Vancouver-based warehouse stocks 45-, 60-, and 90-minute rated panels for next-day delivery to job sites across the Lower Mainland. Key supply chain advantages include:
- Local Inventory: Pre-cut panels for standard sizes reduce lead times.
- Technical Support: In-house engineers assist with specification and installation guidance.
- Compliance Documentation: Full ULC test reports and BCBC compliance letters provided with every order.
This local infrastructure ensures that Vancouver contractors can maintain project schedules while meeting stringent fire safety standards.
