Certified Fire Rated Glass Solutions for Mississauga’s High-Rise and Commercial Buildings

Mississauga’s rapid transformation into a major urban center, driven by the Mississauga Official Plan and the intensification of corridors like Hurontario Street, demands construction materials that meet the highest safety standards. For commercial high-rises, mixed-use developments, and institutional buildings, compliance with the Ontario Building Code (OBC) 2024 is non-negotiable, particularly regarding fire separations and egress paths. Antifires provides ULC-certified fire rated glass and glazed systems specifically engineered to meet the stringent fire-resistance ratings (FRR) required by OBC Section 3.1.8 for vertical shafts, exit enclosures, and fire compartments. Our product portfolio includes integrity-only and combined integrity and insulation (EI) rated assemblies, tested to rigorous standards such as CAN/ULC-S104 and ASTM E119, ensuring that architects and contractors in Mississauga can specify glazing solutions that provide both life safety and design flexibility. By integrating certified fire-rated glazing into modern curtain walls and interior partitions, building professionals can achieve the required fire separations without compromising on natural light or spatial aesthetics. For further details on local regulatory requirements, refer to the official Ontario Building Code 2024 documentation.

Ontario Building Code Compliance for Fire Separation in Mississauga Mixed-Use Developments

Mixed-use developments along Mississauga’s transit corridors, such as those near Square One or the future Hazel McCallion LRT line, require robust fire separation strategies. OBC Section 3.1.8 mandates specific fire-resistance ratings (FRR) for vertical shafts and exit enclosures, often demanding 45-minute to 2-hour fire-rated glazing. Antifires supplies fire rated glass systems that meet these requirements, including 60-minute and 120-minute integrity and insulation (EI) rated assemblies. For instance, our 28mm EI60 panels (tested to BS EN 1634-1) provide 66 minutes of integrity and 64 minutes of insulation, making them suitable for interior fire separations in high-rise condominiums. These systems utilize intumescent gel interlayers that activate under heat, forming a rigid insulating barrier to prevent flame and heat transfer. The frames are constructed from G.M.S. hollow steel sections with ceramic wool (3mm–6mm, density 210 kg/m³) and intumescent fire seals (20mm × 4mm), ensuring a complete firestop assembly. This combination allows architects to specify floor-to-ceiling glazed partitions that meet OBC requirements while maintaining open-plan aesthetics in lobby areas and corridor egress paths.

ULC-S104 Classified Fire Rated Glass Grades for Mississauga’s Climate and Acoustic Demands

Mississauga’s climate, characterized by significant temperature fluctuations and high humidity, demands fire-rated glazing that maintains its integrity and thermal performance year-round. The City of Mississauga Building Division enforces ULC-S104 or CAN/ULC-S114 certification for all fire doors and windows in commercial plazas and office towers. Antifires provides documentation packages tailored to these municipal review processes, including test reports and product data sheets. Our fire rated glass grades include:

  • Integrity-only (E): 60, 90, and 120-minute ratings for applications where insulation is not critical, such as vision panels in fire doors.
  • Integrity and Insulation (EI): 30, 60, and 120-minute ratings for full fire separations, such as partitions between tenant spaces in office towers near Square One.
  • Radiation control (EW): 120-minute ratings for areas where radiant heat transmission must be limited, such as exit corridors.

These systems are tested under controlled conditions (ambient temperature 27°C–36°C, relative humidity 43%–90%) to ensure reliable performance in Mississauga’s variable climate.

Fire Rated Glazing for Mississauga’s Institutional and Transit-Oriented Construction Projects

Mississauga’s major infrastructure projects, including the Hazel McCallion LRT extension and school renovations under the Peel District School Board, require fire-rated glazing that meets OBC Section 3.2.4 for egress paths in multi-story buildings. In transit stations and pedestrian tunnels, fire rated glass partitions must provide 60 to 120 minutes of fire resistance to protect evacuation routes. Antifires supplies fire partition solutions that are tested to BS EN 1364-1 and ASTM E119, ensuring compliance with these demanding requirements. For educational buildings, our 10mm FPOS glass (integrity 135 minutes, insulation 16 minutes) is ideal for vision panels in classroom doors and corridor windows, providing both fire safety and visibility for student supervision. These systems incorporate ceramic insulation boards (12mm–15mm) and expansion gaps (3mm–5mm) filled with ceramic fiber to accommodate thermal movement, ensuring long-term reliability in high-traffic institutional settings.

Antifires’ Localized Engineering Support and ULC-Certified Supply Chain for Mississauga Contractors

Mississauga general contractors and glazing subcontractors benefit from Antifires’ pre-engineered fire rated glass and door kits, which simplify OBC compliance submittals. Our fire door systems are supplied with complete documentation, including ULC test reports and installation instructions, reducing the time and cost of municipal approvals.
