Grenada Fire Rated Glass Certified for Local Building Safety and Compliance

Grenada’s building sector operates under the Grenada Building Code (GBC), which aligns with regional Caribbean Community (CARICOM) standards and frequently references international fire test protocols such as BS 476 Part 22 and ASTM E119. For commercial, hospitality, and high-occupancy structures, local regulations mandate the use of certified fire-rated assemblies to ensure safe egress and compartmentation. Fire rated glass systems from Antifires are engineered to meet these requirements, providing tested integrity (E) and insulation (I) ratings from 60 to 120 minutes—critical for stairwells, exit corridors, and lobby enclosures. The Caribbean’s tropical climate imposes additional demands, including resistance to humidity and thermal cycling, which Antifires addresses through multi-layer composite structures and corrosion-resistant G.M.S. steel frames. All products carry third-party certification to BS EN 1634-1 and UL 263, facilitating smooth municipal plan checks and final inspections. For detailed regulatory references, consult the CARICOM Regional Organisation for Standards (CROSQ) portal, which outlines harmonized building safety criteria for member states.

Adhering to Grenada’s Fire Safety Regulations and Caribbean Building Code Standards

Grenada’s fire safety framework, governed by the Grenada Building Code (GBC), mandates that glazed assemblies in commercial and multi-family buildings achieve minimum fire resistance ratings of 60 to 120 minutes for integrity (E) and, where required, insulation (I). These requirements align with the Caribbean Community (CARICOM) Regional Building Code, which references BS 476 Part 22: 1987 and ASTM E119 as benchmark test standards. For exit enclosures and fire-rated corridors, Antifires supplies fire rated glass systems that have undergone third-party testing under BS EN 1364-1 and BS EN 1634-1, ensuring compliance with local approval processes. The table below summarizes typical ratings specified in Grenadian projects:

Rating ClassIntegrity (min)Insulation (min)Typical Application
E6060N/ACorridor vision panels
EI606060Stairwell enclosures
EI120120120High-occupancy compartment walls

Installation specifications require G.M.S. hollow steel frames with 12–15mm fire-rated insulation board, 3–6mm ceramic wool (density 210 kg/m³), and intumescent seals (20mm × 4mm) to maintain system integrity under furnace pressures of 0 ±2Pa after five minutes.

Selecting Fire Rated Glass Grades and Technical Parameters for Tropical Climates

Selecting the appropriate fire-rated glass grade for Grenada’s tropical climate involves evaluating both fire performance and environmental durability. Antifires offers multi-layer composite structures, such as the 28mm EI60 panel (6mm + 5.5mm gel + 5mm + 5.5mm gel + 6mm), which provides 66 minutes integrity and 64 minutes insulation. For projects requiring higher thermal control, the 50mm EI120 system delivers 120 minutes of both integrity and insulation, critical for large hotel lobbies or conference centers. Key technical parameters include:

  • Glass composition: Tempered float glass layers bonded with intumescent gel that expands at ~120°C to form an insulating barrier.
  • Frame integration: Ceramic tape (3–6mm) accommodates thermal expansion gaps of 3–5mm, preventing premature failure.
  • Climate adaptation: All systems are tested under ambient conditions of 27°C–36°C and relative humidity 43%–90%, mirroring Grenada’s coastal environment.

For hospitality projects in St. George’s or Grand Anse, fire partition solutions with EI60 ratings are commonly specified for corridor enclosures, while EI120-rated assemblies are deployed in high-risk zones such as kitchen exhaust shafts and electrical rooms. The use of corrosion-resistant G.M.S. steel frames and stainless steel anchor bolts (M6/M8 at 300–600mm spacing) ensures long-term stability in saline air conditions.

Addressing Fire Protection Demands in Grenada’s Tourism and Commercial Projects

Grenada’s tourism sector—anchored by resorts in St. George’s, Grand Anse, and the Grenadines—demands fire-rated glazing that balances safety with aesthetic transparency. Hotel lobbies, restaurant enclosures, and corridor partitions must achieve 60- to 120-minute fire resistance while maintaining natural light and ocean views. Antifires addresses these requirements with customized fire rated glass systems that integrate with local architectural styles, including aluminum-clad steel frames and tinted interlayers for UV control. For a 300-room resort, typical specifications include:

  • Lobby enclosure: 21mm FPOS glass (integrity 120 min, insulation 30 min) with ceramic wool seals to prevent smoke migration.
  • Restaurant partitions: 26mm door glass (integrity 89–90 min, insulation 68 min) installed in G.M.S. hollow steel frames with intumescent seals.
  • Corridor vision panels: 10mm FPOS (integrity 135 min, insulation 16 min) for high-traffic egress routes.

All systems undergo furnace testing with Type K thermocouples (9–12 channels) and unexposed surface monitoring (10–55 thermocouples) to verify compliance with BS EN 1634-1. Maximum deflection during testing is recorded between 38mm and 152mm toward the furnace, confirming structural stability under thermal stress.

Selecting Antifires for Certified Fire Rated Systems and Localized Support in Grenada

Antifires provides Grenadian developers and contractors with pre-certified fire-rated systems that streamline local approval processes. All products carry third-party certification to BS 476 Part 22 and UL 263, eliminating the need for redundant local testing. Technical support includes pre-shipment compliance checks, installation guidelines tailored to Caribbean building practices, and on-site consultation for complex projects. Key advantages include:

  • Certified performance: Glass systems achieve E60, E90, E120, EI30, EI60, and EI120 ratings, verified under furnace conditions of 0±2Pa pressure and ambient temperatures up to 36°C.
  • Climate-resilient materials: Frames use G.M.S. hollow steel sections with corrosion-resistant coatings, while ceramic wool (density 210 kg/m³) and intumescent seals (20mm × 4mm) maintain integrity in high-humidity environments.
  • Localized logistics: Products are shipped with detailed assembly drawings and expansion gap specifications (3–5mm filled with ceramic fiber) to ensure correct installation.

For projects requiring rapid turnaround, Antifires maintains inventory of standard sizes, including 10mm FPOS and 28mm EI60 panels, reducing lead times. Direct communication with Antifires’ engineering team enables customized solutions for unique architectural requirements, such as curved glazing or oversized door assemblies.
