Murrieta Fire Rated Glass Solutions Certified to California and International Standards

For commercial building projects in Murrieta, California, specifying the correct fire rated glass is not merely a design choice—it is a regulatory necessity governed by the 2022 California Building Code (CBC) and the California Fire Code. As a city within Riverside County, Murrieta enforces strict amendments to these codes, particularly for fire-resistive glazing used in egress corridors, occupancy separations, and stairwell enclosures. Antifires provides certified glazing systems that comply with these localized requirements, ensuring that every assembly meets the stringent fire-resistance criteria mandated by Title 24, which also addresses energy efficiency overlaps with fire-rated assemblies.

All Antifires products are tested under recognized international standards, including ASTM E119 and UL 263, which are the accepted benchmarks for fire resistance in the United States. These tests evaluate critical performance parameters such as Integrity (E)—resistance to flame penetration—and Insulation (I)—control of temperature rise on the unexposed side. For example, the 28mm EI60 panel demonstrates an integrity of 66 minutes and insulation of 64 minutes, making it suitable for applications where both flame and heat barriers are required. Specifiers can rely on Antifires’ documentation to streamline permit approvals, whether for new construction or commercial renovations.

To further support local compliance, architects and engineers are encouraged to review the official California Building Standards Commission resources for the latest code amendments. By integrating Antifires’ certified solutions, Murrieta projects achieve both safety and code adherence without compromising design flexibility.

Murrieta Fire Code Compliance and Local Building Permit Requirements

Murrieta’s enforcement of the 2022 California Building Code (CBC) requires that all fire-resistive glazing in egress corridors, exit passageways, and occupancy separations be listed under UL 263 or ASTM E119. These standards are more rigorous than basic integrity tests, demanding both flame and thermal barrier performance. Antifires addresses this by providing assemblies that have been furnace-tested under controlled conditions, with thermocouple monitoring on both exposed and unexposed surfaces to verify insulation limits—specifically, an average temperature rise not exceeding 140°C and a maximum of 180°C.

Beyond fire safety, Murrieta projects must also comply with Title 24 energy efficiency standards, which can conflict with traditional fire-rated glazing due to thermal bridging. Antifires’ 50mm and 54mm ultra-high-performance glass resolves this by combining multi-layer insulated fire-resistant structures with low U-values, ensuring that energy codes are met without sacrificing fire resistance. For instance, the 21mm FPOS offers 120 minutes of integrity and 30 minutes of insulation, making it suitable for interior partitions where both fire safety and thermal comfort are priorities.

To simplify permit submissions, Antifires provides detailed test reports and compliance certificates that align with Murrieta’s building department expectations. For projects requiring integrity-only solutions, our 60-minute fire rated glass systems are a cost-effective choice for non-loadbearing walls where insulation is not mandatory.

Fire Rated Glass Classification and Performance Parameters for Murrieta Climates

In Murrieta, local fire marshal inspections require that all fire rated glass installed in stairwell enclosures and exit passageways carry a valid UL 263 or ASTM E119 listing. These standards evaluate assemblies under realistic furnace conditions, including pressure differentials of 0±2 Pa and ambient temperatures ranging from 27°C to 36°C. Antifires’ product range is classified into three core performance categories: Integrity (E), Insulation (I), and Radiation (W). For example, the 26mm door glass achieves an integrity of 89–90 minutes and insulation of 68 minutes, making it ideal for fire doors in high-traffic corridors.

The structural composition of these assemblies is critical to their performance. Antifires uses multi-layer tempered glass combined with intumescent gel layers that expand under heat to form a thermal barrier. The 10mm FPOS (3mm float glass + 4mm fire gel + 3mm float glass) provides 135 minutes of integrity and 16 minutes of insulation, while the 28mm EI60 panel (6mm + 5.5mm gel + 5mm + 5.5mm gel + 6mm) delivers 66 minutes of integrity and 64 minutes of insulation. These configurations are supported by G.M.S. hollow steel frames, ceramic wool (density 210 kg/m³), and intumescent fire seals (20mm × 4mm) to ensure system-level performance.

For projects requiring extended protection, such as hospital corridors or multi-story exit enclosures, the 50mm EI120 assembly offers 120 minutes of both integrity and insulation. Specifiers can review our 120-minute fire rated glass for high-demand applications in Murrieta.

Building Application Scenarios and Engineering Project Demands in Murrieta

Murrieta’s growing commercial sector—including healthcare facilities, educational campuses, and mixed-use developments—demands fire rated glass that balances safety with aesthetic transparency. In stairwell enclosures, for instance, the 26mm door glass (89–90 minutes integrity, 68 minutes insulation) provides a reliable barrier against both flame and heat, ensuring safe egress during emergencies. For occupancy separations in office buildings, the 21mm FPOS (120 minutes integrity, 30 minutes insulation) allows natural light transmission while meeting fire-resistance requirements.

In hospital corridors, where patient evacuation is critical, the 28mm EI60 panel (66 minutes integrity, 64 minutes insulation) offers extended protection against radiant heat, reducing the risk of burn injuries. Similarly, educational facilities in Murrieta benefit from E90 glass (6mm, 90 minutes integrity) for interior partitions that require visual connectivity without compromising fire safety. These assemblies are installed with M6/M8 anchor bolts at 300–600mm spacing and 3–5mm expansion gaps filled with ceramic fiber to accommodate thermal movement.

For commercial renovations in older Murrieta buildings, Antifires’ 15mm FPOS (132 minutes integrity, 33–34 minutes insulation) can be retrofitted into existing steel frames, minimizing structural changes. Our documentation supports streamlined permit approvals, ensuring that project timelines are maintained.
