Aligning with Quebec City’s Fire Safety Codes and the National Building Code of Canada 2020
The Quebec Construction Code and NBC 2020 classify fire-resistance ratings based on occupancy and building height, requiring glazed assemblies to maintain integrity (E) and often insulation (I) for specified durations. Antifires’ systems are engineered to meet these classifications, with products tested to CAN/ULC-S104 for fire doors and ULC-S101 for wall assemblies. For instance, a 45-minute fire separation in a mixed-use building may require an EI45 rating, while egress corridors in high-rise structures often demand EI60 or EI90 performance. The glass composition, such as the 28mm multi-layer structure (6mm glass + 5.5mm gel + 5mm glass + 5.5mm gel + 6mm glass), provides certified insulation by limiting temperature rise on the unexposed side to an average of 140°C and a maximum of 180°C. Frame integration is equally critical; Antifires uses G.M.S. hollow steel sections with ceramic wool (density 210 kg/m³) and intumescent seals (20mm x 4mm) to prevent heat transfer and maintain structural stability under furnace pressures of 0 ±2Pa. This technical precision ensures that Quebec City projects achieve compliance without compromising design flexibility.
Selecting Fire Rated Glass Grades for Quebec City’s Climate and Building Typologies
Selecting the correct fire-rated glass grade for Quebec City’s diverse building typologies requires a deep understanding of spatial separation rules and unprotected opening allowances. For commercial towers in Sainte-Foy, an E90 integrity-only rating may suffice for interior partitions where insulation is not critical, while institutional buildings like schools require EI60 assemblies to protect occupants in egress routes. Antifires provides a range of certified solutions, from 10mm FPOS glass (135-minute integrity, 16-minute insulation) for low-rise applications to 50mm ultra-high-performance units that achieve EI120 for fire-rated walls in industrial zones. The ULC label on each product simplifies RBQ inspections, as it confirms compliance with Canadian national standards. For heritage structures in Vieux-Québec, where frame depth is limited, the 21mm FPOS composite glass (120-minute integrity, 30-minute insulation) offers a slim profile that fits existing masonry openings while meeting modern fire separation requirements. This adaptability ensures that Quebec City specifiers can match performance to project-specific risk profiles, from residential conversions to high-occupancy assembly halls.
Meeting Quebec City’s Building Application Demands: From Historic Facades to New Industrial Zones
Quebec City’s unique architectural heritage, particularly in the Vieux-Québec UNESCO district, presents specific challenges for fire-rated glazing. Antifires addresses this with custom fire-rated windows that replicate historic profiles—such as multi-pane steel frames with divided lights—while integrating certified fire-resistant glass. For hotel and residential conversions of 19th-century buildings, these systems achieve a 45-minute fire separation rating as required by the Quebec Construction Code, using a 10mm or 15mm FPOS glass that fits within existing masonry openings. The installation process incorporates ceramic fiber expansion gaps (3mm–5mm) and M6 anchor bolts at 300mm spacing to accommodate thermal movement without compromising integrity. In contrast, new industrial zones like those in La Cité-Limoilou demand high-performance EI120 assemblies for fire barriers between storage areas and production lines. Antifires’ 50mm multi-layer insulated glass provides both thermal insulation and structural resistance, with test data showing maximum deflection of 38mm–152mm toward the furnace under standard fire conditions. This dual capability ensures that Quebec City’s building stock, from historic facades to modern logistics centers, receives appropriate fire protection without sacrificing architectural authenticity or operational safety.
Why Quebec City Specifiers Trust Antifires for Certified Fire Protection Systems
Antifires has established a reputation among Quebec City specifiers by providing direct ULC-listed product documentation and bilingual technical support (French/English) that aligns with RBQ submission requirements. The company’s localized inventory reduces lead times for critical projects, ensuring that fire-rated glass and door systems are available when needed. For fire door systems, Antifires offers assemblies tested to BS EN 1634-1 and CAN/ULC-S104, with certified ratings from E60 to EI120. On-site consultation services help contractors navigate permit submissions, providing detailed test reports and installation guidelines that reference specific furnace conditions (ambient temperatures of 27°C–36°C, relative humidity 43%–90%) to validate performance under real-world scenarios. The use of certified components—such as intumescent seals, ceramic wool, and fire-rated insulation boards (12mm–15mm)—ensures that every installation meets the stringent requirements of the Quebec Construction Code. By combining technical expertise with regulatory knowledge, Antifires delivers a streamlined path to compliance for Quebec City’s most demanding projects, from heritage restorations to large-scale commercial developments.
