Milwaukee Fire Rated Glass Certified for Local Building Safety Standards

Fire-rated glazing plays a critical role in the passive fire protection strategy of commercial buildings in Milwaukee, Wisconsin. Compliance with the Wisconsin Commercial Building Code (Comm 62) and the 2021 International Building Code (IBC) Chapter 7 mandates the use of fire-resistance-rated assemblies in specific applications, including egress corridors, stairwell enclosures, and fire barriers. Antifires supplies certified fire-rated glass and framing systems that meet or exceed the rigorous requirements of ASTM E119 and UL 263, the primary standards referenced by local authorities having jurisdiction (AHJ). For high-occupancy developments, such as those in the Fiserv Forum district, these codes require tested assemblies that maintain integrity and, where specified, insulation against heat transfer. The integration of intumescent gel technology within multi-layer glass structures ensures that vision panels and full-height partitions can achieve fire resistance ratings from 60 to 120 minutes without sacrificing design transparency. Milwaukee building professionals can reference the IBC Chapter 7 official documentation for detailed requirements on fire-resistance-rated glazing. Antifires provides technical submittals and test reports that directly support permit applications and plan reviews for projects across the greater Milwaukee area.

Milwaukee Building Code Compliance for Fire Rated Glass and Partition Systems

Adherence to the Wisconsin Commercial Building Code (Comm 62) and IBC 2021 is non-negotiable for fire-rated glazing installations in Milwaukee. These codes specify that glazing in fire-resistance-rated walls, particularly in egress corridors and stairwell enclosures, must be tested as part of a complete assembly, including the frame and seals. For projects in high-occupancy zones such as the Fiserv Forum district, the required fire rating often reaches 60 to 120 minutes for integrity (E) and, in critical locations, insulation (I). Antifires’ systems, certified under UL 263 and ASTM E119, are designed to meet these stringent local requirements. The assemblies incorporate G.M.S. hollow steel frames with intumescent seals and ceramic wool to prevent gap penetration, ensuring that the entire system performs as a unified barrier. Milwaukee architects and specifiers must ensure that the chosen glazing system is listed for the specific wall type and fire-resistance rating required by the code. Antifires provides detailed engineering data and compliance documentation to simplify the approval process with local building departments.

Selecting Fire Rated Glass Grades for Milwaukee’s Climate and Structural Demands

Selecting the appropriate fire-rated glass grade for Milwaukee projects requires careful consideration of both fire performance and environmental factors. The city’s climate, with significant temperature fluctuations and high humidity, demands glazing systems that maintain structural integrity under thermal stress. For mixed-use developments along the Milwaukee Riverwalk, specifying 45-minute (E45) or 60-minute (E60) integrity-only glass is common for interior vision panels where insulation is not required. However, for applications adjacent to exit enclosures or fire barriers, EI60 or EI120 rated assemblies are necessary to control heat transfer. Antifires’ 28mm EI60 and 50mm EI120 multi-layer composite glasses incorporate intumescent gel layers that activate under fire exposure, forming an insulating barrier that limits temperature rise on the unexposed side. The glass composition—such as 6mm + 5.5mm gel + 5mm + 5.5mm gel + 6mm—is engineered to withstand the thermal shock of cold ambient conditions while maintaining certified fire performance. Integration with local fire department (MFD) inspection protocols is streamlined through Antifires’ provision of full assembly test reports and installation certification.

Milwaukee Commercial and Industrial Applications for Fire Rated Glass Products

Milwaukee’s commercial and industrial sectors present diverse requirements for fire-rated glazing, particularly in healthcare and institutional facilities. For example, the Froedtert Hospital expansions require fire-rated vision panels in ICU doors and corridor glazing that maintain visibility for staff while preserving 2-hour fire barriers. In such critical environments, EI120-rated glass (up to 120 minutes of both integrity and insulation) is essential to protect patients and equipment from radiant heat and flame spread. Antifires supplies 50mm and 54mm ultra-high-performance glass assemblies that meet these stringent demands, with certified performance under BS EN 1634-1 and ASTM E119. The systems are installed using ceramic wool (3mm–6mm, density 210 kg/m³) and intumescent fire seals to ensure a tight, gap-free fit within steel frames. For industrial applications, such as manufacturing plants or warehouses requiring fire-rated partitions, E90 or E120 integrity-only glass provides a cost-effective solution for compartmentation without sacrificing natural light. Antifires’ technical team assists in specifying the correct glass thickness and frame configuration for each unique project scenario, ensuring compliance with both fire codes and operational needs.

Why Milwaukee Architects and Contractors Choose Antifires Fire Rated Systems

Milwaukee architects and contractors increasingly choose Antifires for fire-rated glass systems due to the combination of certified performance and logistical reliability. All products are UL-certified and tested to ASTM E119 and BS 476 Part 22, providing the authoritative documentation required for building permits and final inspections. Antifires maintains local warehousing in Chicago, enabling 3-5 day delivery to Milwaukee job sites—a critical advantage for tight construction schedules common in the region’s commercial developments. The company offers a full range of products, including 90-minute fire-rated glass for integrity-only applications and 120-minute fire-rated glass for combined integrity and insulation requirements. Additionally, fire-rated glass partitions from Antifires provide design flexibility without compromising safety. The use of G.M.S. hollow steel frames and intumescent seals ensures that every assembly is engineered for long-term durability and code compliance.

Frequently Asked Questions (FAQ)

Yes, Antifires fire-rated glass systems are designed to comply with the Wisconsin Commercial Building Code (Comm 62) and 2021 IBC Chapter 7 requirements for Milwaukee projects. All assemblies are tested to ASTM E119 and UL 263 standards, which are the primary test methods referenced by these codes. Antifires provides full assembly test reports and compliance documentation to support permit applications and plan reviews with local building departments. The glass and frame systems are engineered to meet the specific fire-resistance ratings required for egress corridors, stairwell enclosures, and fire barriers in Milwaukee’s commercial buildings. For projects requiring additional verification, Antifires can supply third-party certification reports from accredited testing laboratories.

For exterior glazing in Milwaukee’s cold climate, a fire rating of 60 minutes (E60) is often recommended for integrity-only applications, such as vision panels in exterior walls that are part of a fire-resistance-rated assembly. However, if the glazing is adjacent to an exit enclosure or fire barrier, a higher rating such as EI60 or EI120 may be required to control heat transfer and radiant heat flux. Antifires’ multi-layer composite glasses, such as the 28mm EI60 and 50mm EI120 systems, are designed to withstand thermal shock and maintain performance in low ambient temperatures. The intumescent gel layers within these assemblies provide both integrity and insulation, ensuring that the unexposed side remains below the maximum temperature rise limits specified by ASTM E119.

Antifires offers rapid delivery of UL-certified fire-rated glass to Milwaukee construction sites, with typical lead times of 3-5 business days from order confirmation. This is made possible by maintaining local warehousing in Chicago, which serves as a central distribution hub for the Midwest region. For standard products, such as E60 and EI60 rated glass in common sizes, inventory is readily available for immediate shipment. Custom sizes and specialized assemblies may require additional fabrication time, but Antifires’ logistics team works closely with contractors to align delivery schedules with project milestones. This fast turnaround minimizes delays and helps maintain tight construction timelines common in Milwaukee’s commercial and industrial projects.
