Mesa Fire Code Adoption and UL 10C Compliance for Glazed Assemblies
Mesa’s building code framework, based on the 2021 IBC with Arizona amendments, requires fire-resistance-rated glazing to withstand positive pressure conditions as defined by UL 10C. Antifires’ fire rated glass assemblies are tested to maintain structural integrity under these conditions, preventing flame penetration and hot gas leakage for up to 120 minutes in high-rise condominiums. The assemblies utilize intumescent interlayers that expand under heat, sealing gaps between glass panes and frames. Key technical features include:
- Frame construction: G.M.S. hollow steel sections with 12–15mm fire-rated insulation board.
- Sealant system: Ceramic wool (3–6mm, density 210 kg/m³) and intumescent fire seals (20mm × 4mm).
- Test performance: Integrity maintained for 66–135 minutes depending on glass composition, with insulation failure occurring between 16–86 minutes.
These parameters ensure compliance with Mesa’s exit corridor requirements, particularly in buildings exceeding 75 feet in height along the US 60 corridor.
Selecting Fire Rated Glass with ASTM E119 and NFPA 252 Ratings for Mesa Projects
For Mesa’s mixed-use developments near downtown, specifying fire rated glass with ASTM E119 and NFPA 252 ratings is critical for both safety and acoustic performance. Antifires offers ceramic and laminated intumescent interlayer glass tested to deliver 45- and 60-minute fire resistance. The glass composition, such as the 26mm door glass (5mm + 5.5mm gel + 5mm + 5.5mm gel + 5mm), achieves integrity for 89–90 minutes and insulation for 68 minutes. Fire doors comply with NFPA 252, providing STC ratings up to 42 for noise mitigation in multi-family units near Falcon Field. Selection criteria include:
| Glass Type | Integrity (min) | Insulation (min) | STC Rating |
| 10mm FPOS | 135 | 16 | 35 |
| 28mm EI60 panel | 66 | 64 | 42 |
| 50mm EI120 | 120 | 120 | 45 |
These ratings ensure compliance with IBC Section 715 for vision panels without requiring sprinkler trade-offs.
Fire Rated Solutions for Mesa’s Healthcare and Educational Building Expansions
Mesa’s Banner Health campus and Mesa Public Schools modernization projects demand fire-rated partitions that balance safety with functionality. Antifires provides EI-classified fire glass for 30-minute integrity in glazed sidelights, meeting IBC Section 715 for vision panels in patient rooms and science labs. The glass structure, such as the 15mm FPOS (multi-layer tempered glass with intumescent gel), achieves integrity up to 132 minutes and insulation for 33–34 minutes, suitable for corridor separations. In healthcare settings, radiation control (W) is critical; Antifires’ EW120-rated glass limits radiant heat transmission to below 15 kW/m², protecting adjacent egress paths. For educational labs, the fire partition solutions include ceramic wool seals and intumescent tapes that maintain airtightness under fire exposure, preventing smoke migration. These systems are tested per BS EN 1364-1 and BS 476 Part 22, ensuring deflection limits of 38–152mm toward the furnace do not compromise structural integrity.
Why Mesa Contractors Trust Antifires for UL-Listed Fire Resistant Materials
Mesa contractors trust Antifires for UL-listed and ISO 9001-certified fire resistant materials, with local stock in Arizona enabling rapid delivery for projects near Red Mountain. The engineering team reviews Mesa-specific fire barrier plans per IBC Chapter 7, reducing approval delays for fire-rated door frames and glass. Antifires’ fire door systems are tested under positive pressure conditions, with frame assemblies using M6/M8 anchor bolts at 300–600mm spacing and expansion gaps of 3–5mm filled with ceramic fiber. Key advantages include:
- Certified ratings: E60, E90, E120 for integrity; EI30, EI60, EI120 for insulation.
- Test conditions: Furnace pressure maintained at 0 ±2Pa, with ambient temperatures of 27–36°C and relative humidity 43–90%.
- Failure modes: Cotton pad ignition and sustained flaming monitored per ASTM E119 protocols.
This technical rigor ensures Mesa’s senior living facilities meet both fire safety and acoustic requirements without compromising design flexibility.
