Adherence to Turkish TS 12654 Fire Safety Codes and Izmir Seismic Building Regulations
Izmir’s location on active fault lines necessitates a dual focus on seismic resilience and fire containment. The Turkish standard TS 12654 outlines the performance criteria for fire-resistant glazing, while TBDY 2018 governs structural behavior during earthquakes. Antifires fire-rated glass systems are engineered to bridge these two regulatory frameworks. During testing, assemblies are subjected to furnace pressures of 0 ±2 Pa, simulating realistic fire dynamics, while the framing systems—utilizing G.M.S. hollow steel sections and ceramic wool (density 210 kg/m³)—provide the necessary rigidity to withstand building sway. In a seismic event, a post-earthquake fire can occur within minutes; therefore, the glass must retain its integrity even if the building frame has shifted. Antifires products, such as the 21mm FPOS multi-layer composite glass, have demonstrated integrity up to 120 minutes, ensuring that escape routes remain viable. For Izmir projects, specifying systems that combine TS 12654 compliance with seismic gap detailing (3–5 mm expansion gaps filled with ceramic fiber) is critical. This ensures that the glazing does not become a brittle failure point, but rather a reliable barrier against fire spread in the critical minutes following a tremor.
Fire Rated Glass Grade Selection: E-Class Integrity vs. EW-Class Insulation for Izmir Climates
The selection between E-Class (Integrity only) and EW-Class (Integrity plus Radiation control) fire rated glass is heavily influenced by Izmir’s coastal humidity and specific application zones. For stairwells and escape corridors in high-rise residential towers near Alsancak, E60 or E90 rated glass (tested to BS 476 Part 22) provides the necessary barrier against flame and hot gas penetration. However, for hotel corridors and commercial lobbies where occupant proximity to the glass is higher, EW30 or EW60 ratings are recommended to control radiant heat transmission, keeping the unexposed side below critical thresholds. Antifires offers laminated glass options with UV-stable interlayers that resist degradation from Aegean salt spray and intense sunlight—a key factor for external facades. The table below summarizes the recommended grades for typical Izmir applications:
| Application |
Recommended Rating |
Key Standard |
Humidity Consideration |
| Residential Stairwells |
E60 / E90 |
TS EN 1634-1 |
Standard laminated |
| Hotel Corridors |
EW30 (Insulation) |
EN 13501-2 |
UV-stable interlayer |
| Commercial Atriums |
EW60 / EI60 |
BS 476 Part 22 |
Salt corrosion resistant frame |
| Facade Glazing |
E120 (Integrity) |
ASTM E119 |
Sealed edge units |
This technical differentiation ensures that the glass not only stops fire but also provides a safe environment for evacuation, even in Izmir’s challenging microclimate.
Application Demands in Izmir’s Mixed-Use Towers and Historic Port District Renovations
Izmir’s urban landscape is a mix of historic port district renovations in Alsancak and modern mixed-use towers in Bayraklı. Each scenario presents distinct fire protection demands. In the historic port district, retrofitting 19th-century buildings with fire-rated glazing requires slim-profile systems that do not compromise architectural heritage. Antifires provides 60-minute fire rated glass with a 10mm FPOS structure (3mm float + 4mm gel + 3mm float) that fits into existing steel or timber frames without extensive structural modification. For new high-traffic commercial lobbies in Konak, where large glazed spans are desired, the 26mm door glass (5mm + 5.5mm gel + 5mm + 5.5mm gel + 5mm) offers both integrity (89–90 minutes) and insulation (68 minutes), providing a safe barrier for dense occupant loads. In residential towers, EI60 rated partitions using 28mm glass (6mm + 5.5mm gel + 5mm + 5.5mm gel + 6mm) are ideal for separating apartment units from common corridors. The maximum deflection of these systems during testing (38mm to 152mm toward the furnace) is accounted for in the structural design, ensuring that the glass panels do not dislodge under fire or seismic loads. This adaptability makes Antifires a reliable partner for both preservation and new construction projects in Izmir.
Antifires Localized Supply Chain and Certified Testing for Izmir Construction Projects
Antifires has established a localized supply chain to support Izmir’s construction sector, maintaining a stock hub for rapid delivery of fire rated glass, doors, and framing components. All products are backed by certified test reports under TS EN 1634-1 and BS 476 Part 22, ensuring that documentation is readily available for Izmir Municipality permit submissions. The technical team assists with specification writing, helping architects and contractors align project requirements with local fire safety codes. For installations, the company provides detailed guidelines on fixing spacing (M6/M8 anchor bolts at 300–600mm intervals) and sealant application (intumescent fire seals of 20mm × 4mm), ensuring that field performance matches laboratory results. The 120-minute fire rated glass systems, with their multi-layer insulated structure, are particularly suited for high-risk zones in Izmir’s industrial and commercial buildings. By offering a complete package—from product supply to compliance documentation—Antifires streamlines the approval process, reduces project delays, and ensures that every installation meets the rigorous standards demanded by Turkish regulations and Izmir’s seismic reality.
