Yes, Antifires fire rated glass systems are designed to comply with Long Beach’s specific seismic and coastal amendments to the 2022 California Building Code (CBC). The products are tested to UL 263 (ASTM E119) and BS 476 Part 22, which evaluate performance under fire exposure while accounting for structural movement. For seismic compliance, Antifires uses G.M.S. hollow steel frames with M8 anchor bolts at 300–600mm spacing and ceramic fiber-filled expansion gaps (3–5mm) to accommodate lateral displacement. The coastal salt-air environment is addressed through corrosion-resistant materials and multi-layer glass construction with intumescent gel interlayers, which maintain integrity during thermal expansion. All assemblies come with certified test reports that can be submitted to the Long Beach Development Services Department for plan check approval.
For a fire-rated glass window in a Long Beach hotel stairwell enclosure, the 2022 California Building Code requires a minimum 2-hour fire-resistance rating (120 minutes). This applies to both integrity (E) and, in most cases, insulation (I) to prevent heat transfer that could ignite materials on the unexposed side. Antifires recommends the 50mm or 54mm EI120 glass system, which offers integrity and insulation up to 120 minutes as certified under UL 263 and BS EN 1634-1. For stairwells where radiant heat control is a secondary concern, an E120 rated assembly may be acceptable, but insulation-rated glass is strongly advised to protect egress paths. The glass must be installed in a steel frame with intumescent seals and ceramic wool to maintain the rating under positive furnace pressure conditions.
Antifires provides comprehensive support for UL documentation and local permitting in Long Beach. Each product is supplied with a certified test report from an accredited laboratory, detailing the fire-resistance rating (e.g., E90, EI60, or EI120) and the specific test standard used (UL 263 or ASTM E119). For a fire door replacement, Antifires’ technical team can provide the manufacturer’s listing, installation instructions, and a product data sheet that matches the existing frame and hardware. These documents are formatted for submission to the Long Beach Development Services Department as part of the permit application. Additionally, Antifires offers guidance on proper anchoring, gap filling (ceramic fiber, 3–5mm), and sealant use to ensure the assembly meets local seismic and coastal amendments. This reduces delays during plan check and field inspection.
