Meeting Wichita’s Strict Fire Separation Requirements Under the 2024 IBC
Wichita’s commercial building permits, governed by the 2024 IBC Section 716, demand fire-resistance-rated glazing in critical areas such as exit enclosures and corridor partitions. For projects like three-story office complexes near the Intrust Bank Arena, a minimum 45-minute fire-protection rating is often required for opening protectives. Antifires addresses these mandates with products tested to BS 476 Part 22 and BS EN 1634-1, ensuring integrity against flame penetration and sustained flaming. The 10mm FPOS glass, for instance, achieves 135 minutes of integrity, far exceeding local minimums, while the 26mm door glass provides 89 minutes of integrity and 68 minutes of insulation—critical for egress pathways. The city’s adopted amendments also emphasize the use of fire-rated frames and intumescent seals, with Antifires specifying G.M.S. hollow steel sections and 3mm to 6mm ceramic wool to maintain system stability. For high-rise applications, the 60-minute fire-rated glass (E60) is a standard choice, offering a maximum 25 sq. ft. individual lite area per UL 263 classifications. This aligns with Wichita’s focus on sprinklered atrium designs, where glass must withstand both fire and hose-stream pressures. By integrating 60-minute fire rated glass for doors and partitions, specifiers can achieve compliance without compromising aesthetic transparency in commercial lobbies and stairwells.
Specifying 60-Minute Fire Rated Glass for Wichita’s Mixed-Use High-Rise Glazing
For Wichita’s evolving downtown skyline, particularly along the Douglas Avenue corridor, mixed-use high-rise projects require 60-minute fire-rated glazing that meets ASTM E119 hose-stream tests. Antifires offers both ceramic and laminated options, each engineered to maintain structural integrity under extreme thermal stress. The 15mm FPOS glass, with integrity up to 132 minutes and insulation for 33 minutes, provides a robust solution for atrium applications where smoke control and radiant heat reduction are paramount. Test data from BS EN 1364-1:1999 confirms that these assemblies limit average temperature rise on the unexposed side to ≤140°C, ensuring occupant safety during egress. The framing system utilizes fire-rated insulation boards (12mm to 15mm) and intumescent fire seals (20mm × 4mm) to prevent gap penetration, a common failure mode in high-rise glazing. For sprinklered atriums, the 21mm FPOS glass offers 120 minutes of integrity and 30 minutes of insulation, balancing thermal performance with weight constraints. This is particularly relevant for Wichita’s mixed-use towers, where large lite areas (up to 25 sq. ft.) must comply with IBC Section 716.2.2.1. Antifires’ UL-classified systems undergo rigorous furnace testing with Type K thermocouples and pressure monitoring at 0 ±2Pa, replicating real-world fire conditions.

Retrofit Demands for Fire Windows in Wichita’s Historic Warehouse Districts
Wichita’s Historic Delano District and Old Town conversions present unique challenges for fire window retrofits, where preserving original steel frames is essential for local preservation board approvals. Antifires supplies 45-minute fire-rated glazing units with a maximum 1/4-inch thickness to fit existing mullions, ensuring compliance with 3/4-hour fire protection ratings under IBC Section 716. The 8mm glass system, tested to BS 476 Part 22, achieves 73 minutes of integrity, while the 6mm E90 glass offers 90 minutes—both suitable for historic window openings. These units incorporate ceramic wool (3mm to 6mm, density 210 kg/m³) and intumescent seals to compensate for irregular frame gaps common in older structures. Expansion gaps of 3mm to 5mm are filled with ceramic fiber to prevent thermal bridging, a critical detail in masonry walls typical of Delano’s brick warehouses. Antifires also provides cut sheets that detail anchor bolt spacing (M6/M8 at 300–600mm intervals) to meet Sedgwick County fire marshal requirements. This approach allows developers to maintain historical aesthetics while achieving modern fire safety standards, a balance essential for projects near the Wichita Art Museum or Union Station. For detailed specifications, review the single-layer fire rated glass configurations ideal for retrofit window applications.
Antifires Local Stock and Code Liaison Support for Wichita Fire Door Projects
Antifires distinguishes itself from generic importers by maintaining a Midwest distribution hub that ensures 5-day delivery to Wichita job sites, a critical advantage for time-sensitive projects at Spirit AeroSystems or Wesley Medical Center expansions. The company’s in-house code specialists review Sedgwick County fire marshal plan comments, providing UL-listed fire doors and glazing cut sheets that streamline inspections. For fire door assemblies, Antifires specifies 26mm door glass (5mm + 5.5mm gel + 5mm + 5.5mm gel + 5mm) with 89 to 90 minutes of integrity and 68 minutes of insulation, meeting NFPA 80 inspection requirements for latching, clearance, and self-closing devices. The 28mm EI60 panel, with 66 minutes of integrity and 64 minutes of insulation, is a preferred choice for corridor doors in healthcare facilities. Each system is tested to BS EN 1634-1:2008 with furnace pressures of 0 ±3Pa after 5 minutes, ensuring repeatable performance. Antifires also offers 50mm and 54mm ultra-high-performance glass (EI120) for stairwell enclosures, providing 120 minutes of both integrity and insulation. This local stock and code liaison support reduces project delays, allowing architects and contractors to focus on design rather than compliance hurdles.
