Adhering to Oklahoma City Fire Safety Codes and the 2024 International Building Code Amendments
Oklahoma City’s adoption of the 2024 IBC includes specific amendments that address the region's unique climatic challenges, particularly for buildings located in wind-borne debris zones. These amendments require that fire-rated glazing systems not only withstand fire exposure but also resist impact from wind-driven projectiles. Antifires addresses this dual requirement by offering systems tested to UL 263 for fire resistance, with frame assemblies constructed from G.M.S. hollow steel sections and reinforced with ceramic wool (density 210 kg/m³) for thermal and structural integrity. For commercial and multi-family buildings, the use of intumescent fire seals (20mm × 4mm) within the framing system is critical to maintaining the fire barrier during a fire event. The local code amendments also mandate specific anchor bolt spacing (300–600mm) for curtain wall and storefront applications, a detail that Antifires incorporates into its engineered installation guidelines. By specifying products that meet both the fire-resistance and wind-load requirements of the Oklahoma City amendments, project teams can streamline the approval process with local building authorities.
Selecting Fire Rated Glass Grades for Oklahoma City’s Climate and Occupancy Classifications
Selecting the appropriate fire-rated glass grade for Oklahoma City projects requires a thorough understanding of both the building's occupancy classification and the local climate. For office towers and healthcare facilities, where compartmentation and safe egress are paramount, the NFPA 80 standard for fire door assemblies and NFPA 252 for window assemblies dictate the performance criteria. Antifires offers a range of certified glass compositions tailored to these needs. For example, the 28mm EI60 panel (tested to 66 minutes integrity and 64 minutes insulation) is ideal for stairwell enclosures, while the 50mm EI120 system provides up to 120 minutes of both integrity and insulation for critical fire barriers. The following table outlines typical applications based on performance ratings:
| Performance Rating | Typical Application | Glass Structure Example |
| E60 (Integrity only) | Interior partitions, vision panels in doors | 6mm E90 glass |
| EI60 (Integrity + Insulation) | Stairwells, corridor enclosures, school zones | 28mm multi-layer composite |
| EI120 (Integrity + Insulation) | Hospital fire barriers, high-risk storage areas | 50mm ultra-high-performance glass |
This structured approach ensures that the selected glazing meets the specific fire-resistance time required by the IBC for each occupancy type, while also addressing thermal insulation to prevent heat transfer to unexposed sides.
e】Fire Rated Glass Oklahoma City: Certified Solutions for Local Building Compliance and Safety
In Oklahoma City, the integration of fire-rated glazing into fire door systems and fire partition solutions is governed by the detailed requirements of NFPA 80 and the local building code. For fire door assemblies, the glazing must be tested as part of the complete door unit, including the frame, hinges, and hardware, under BS EN 1634-1 or its ASTM equivalent. Antifires provides fire partition solutions that incorporate certified glass panels, such as the 26mm door glass (89–90 minutes integrity, 68 minutes insulation), which is suitable for rated door assemblies in commercial corridors. The installation process is critical, requiring a 3mm to 5mm expansion gap filled with ceramic fiber to accommodate thermal movement without compromising the seal. For curtain wall systems, the use of 12mm to 15mm fire-rated insulation boards behind the framing is essential to prevent heat transfer through the mullions. By following these engineered specifications, Oklahoma City contractors can ensure that the entire assembly—glass, frame, and sealant—performs as a unified fire barrier during a fire event.
Why Oklahoma City Engineers Choose Antifires for UL-Certified Fire Rated Glass and Doors
Oklahoma City engineers and specifiers increasingly turn to Antifires for UL-certified fire rated glass and door systems due to the company’s commitment to verifiable test data and localized technical support. Unlike generic products, Antifires provides detailed engineering reports that reference specific test conditions, such as furnace pressure of 0 ±2Pa and ambient test temperatures of 27°C to 36°C, ensuring that the performance data is reliable for real-world applications. The company’s product line includes systems tested to ASTM E119 and BS 476 Part 22, offering ratings from E60 to EI120. For complex projects, such as those in Oklahoma City’s downtown high-rise district, Antifires offers customized solutions like the 54mm ultra-high-performance glass for demanding fire-resistance requirements. Furthermore, the company’s technical team assists with permit submission by providing all necessary test certifications and installation details, including M6/M8 anchor bolts at specified spacing. This level of support reduces risk for the engineering firm and ensures that the final installation meets the strictest local code interpretations.
