Adhering to Omaha’s Enforcement of the 2021 IBC and Local Fire Codes
Omaha’s building code enforcement, based on the 2021 IBC with local amendments, requires fire-resistance-rated glazing in specific applications such as exit corridors, stairwells, and hazardous areas like boiler rooms and storage spaces. Antifires’ product line is fully compliant with ASTM E119 and NFPA 80, ensuring that each assembly—from glazed partitions to door systems—meets the fire-protection ratings mandated by the city’s plan review process. For instance, in high-occupancy structures like the First National Tower, local fire marshals demand third-party certification for assemblies providing 60 to 120 minutes of fire resistance. Antifires offers UL-classified systems, including EI60 and EI120 rated glass, which have demonstrated integrity and insulation performance under rigorous furnace testing. The use of intumescent interlayers and ceramic wool seals in our frames prevents heat transfer and flame penetration, aligning with the IBC’s requirements for smoke and fire containment. Additionally, our systems are designed to accommodate the expansion and contraction demands of Omaha’s climate, with expansion gaps filled with ceramic fiber to maintain seal integrity. For projects requiring detailed documentation, Antifires provides full test reports and compliance certificates, streamlining the approval process with Douglas County building officials.
Selecting Fire Rated Glass Grades for Omaha’s Extreme Temperature Variations
Omaha’s climate, characterized by hot summers and frigid winters, places unique demands on fire-rated glazing systems. Antifires addresses this by offering glass grades that maintain structural integrity and thermal performance across extreme temperature variations. For example, our 10mm FPOS glass, tested to BS 476 Part 22, provides 135 minutes of integrity and 16 minutes of insulation, making it suitable for interior partitions where rapid temperature changes are less severe. For exterior applications or areas near unheated spaces, we recommend 21mm FPOS or 28mm EI60 panels, which offer enhanced insulation (up to 64 minutes) and resistance to thermal shock. These multi-layer assemblies incorporate intumescent gels that activate at high temperatures, forming a rigid insulating barrier while the glass layers remain stable. Local fire marshals require third-party certification for assemblies in high-occupancy structures like the First National Tower, and Antifires’ UL 263 and UL 10C listings provide verified performance for 45- to 120-minute fire protection ratings. The table below summarizes key product grades suitable for Omaha’s climate:
| Glass Grade | Integrity (min) | Insulation (min) | Application |
|---|
| 10mm FPOS | 135 | 16 | Interior partitions, moderate climate exposure |
| 21mm FPOS | 120 | 30 | Interior/exterior, enhanced thermal resistance |
| 28mm EI60 | 66 | 64 | Doors, high-insulation requirements |
| 50mm EI120 | 120 | 120 | High-rise, maximum fire and thermal protection |
Meeting Omaha’s Construction Needs: From Downtown High-Rises to Suburban Schools
Omaha’s construction landscape spans from downtown high-rises like the First National Tower to suburban schools and healthcare facilities. Each project type requires tailored fire-rated glazing solutions. For high-rise office buildings, Antifires supplies 50mm EI120 glass systems that provide two hours of both integrity and insulation, meeting the IBC’s requirements for exit enclosures and fire barriers. These assemblies feature multi-layer insulated structures with intumescent interlayers, ensuring minimal heat transfer and structural stability under fire conditions. In suburban schools, where safety and visibility are critical, Antifires offers 26mm door glass with 90 minutes of integrity and 68 minutes of insulation, ideal for corridor doors and classroom partitions. For healthcare facilities, such as those near the University of Nebraska Medical Center, 28mm EI60 panels provide the necessary fire resistance while allowing natural light into patient rooms and waiting areas. Antifires also supports historic building renovations in Omaha’s Old Market district, offering custom-sized fire rated windows that match existing architectural styles without compromising safety. All systems are installed using G.M.S. hollow steel frames and ceramic wool seals, ensuring compatibility with local construction practices and code requirements. By providing a range of certified products, Antifires enables contractors to select the optimal solution for each unique project scenario, from new construction to retrofits.
