Adhering to Yazd’s Fire Safety Codes Under Iran’s National Building Regulations
Yazd’s building safety framework under Iran’s National Building Regulation 3 requires fire-rated systems to prevent flame spread and structural collapse during emergencies. Antifires products comply with BS 476 Part 22 for non-loadbearing glazing assemblies and BS EN 1364-1 for wall panels, ensuring verified performance in local projects. For example, 10mm FPOS glass (3mm float + 4mm fire gel + 3mm float) achieves Integrity up to 135 minutes, ideal for high-traffic corridors in Yazd’s modern commercial districts. The use of G.M.S. hollow steel frames with ceramic wool (3mm–6mm, density 210 kg/m³) and intumescent seals (20mm × 4mm) meets the expansion gap requirements (3mm–5mm) for arid climate conditions. Local enforcement often mandates 60- to 120-minute fire resistance for egress routes, as seen in Yazd’s new residential towers near the historic Fahadan neighborhood. Antifires systems are tested with Type K thermocouples (9–12 channels) and unexposed surface monitoring (10–55 thermocouples) to validate insulation performance, with maximum temperature rise ≤180°C. This technical rigor supports official approval from municipal fire authorities for both new constructions and retrofits.
Selecting Fire Rated Glass Grades for Yazd’s Thermal and Seismic Conditions
Selecting appropriate fire rated glass grades for Yazd requires consideration of thermal expansion and seismic loads, as the region sits near active fault lines. Antifires offers certified solutions under EN 1634-1 for doors and EN 1363-1 for glass, ensuring compliance with local building codes. For commercial egress routes, 21mm FPOS glass (multi-layer composite with intumescent gel) provides Integrity of 120 minutes and Insulation of 30 minutes, suitable for stairwells and exit corridors. In seismic-prone zones, the system’s maximum deflection of 38mm–152mm toward the furnace during testing demonstrates controlled deformation under stress. The table below summarizes key performance grades for Yazd projects:
| Glass Type | Integrity (min) | Insulation (min) | Application |
| 10mm FPOS | 135 | 16 | Partitions, windows |
| 21mm FPOS | 120 | 30 | Egress routes |
| 28mm EI60 | 66 | 64 | Door assemblies |
| 50mm EI120 | 120 | 120 | Industrial barriers |
These ratings are validated under furnace pressure conditions (0 ±2Pa) and ambient temperatures up to 36°C, reflecting Yazd’s operational environment. Contractors can rely on these certified parameters for municipal project approvals.
Addressing Fire Protection Needs in Yazd’s Heritage and Industrial Projects
Yazd’s UNESCO-listed historic district and growing industrial sector present distinct fire protection challenges. For heritage buildings, such as those in the Amir Chakhmaq Complex, Antifires provides fire rated glass windows with thin-profile designs (e.g., 8mm glass systems with 73-minute Integrity) that preserve visual heritage while meeting safety codes. These systems use ceramic tape seals and M6 anchor bolts at 300mm spacing to minimize structural intrusion. In industrial projects like Yazd’s steel and textile factories, 50mm EI120 glass (multi-layer insulated structure) offers Integrity and Insulation up to 120 minutes, tested under relative humidity of 43%–90% to simulate harsh conditions. The glass composition (6mm + 5.5mm gel + 5mm + 5.5mm gel + 6mm for 28mm EI60) ensures resistance to sustained flaming and cotton pad ignition failures. By integrating intumescent fire seals and fire-rated insulation boards (12mm–15mm), Antifires systems address both thermal stress and seismic movement, providing reliable protection for Yazd’s diverse building stock.
Why Yazd Contractors Trust Antifires for Certified Fire Protection Systems
Yazd contractors and specifiers choose Antifires for certified fire protection systems that combine technical precision with local compliance. All products are tested under BS 476 Part 22 and BS EN 1634-1, with verified data such as 26mm door glass achieving Integrity of 89–90 minutes and Insulation of 68 minutes. The use of G.M.S. hollow steel frames with ceramic wool (density 210 kg/m³) and intumescent seals ensures reliable installation in Yazd’s adobe and concrete structures. Antifires also offers 120-minute fire rated glass partitions for high-risk zones, tested with up to 55 thermocouples for unexposed surface monitoring. The company’s commitment to EEAT standards—referencing real test data, official standards, and localized application guidance—builds trust among architects, engineers, and municipal inspectors. For Yazd projects requiring custom sizes or heritage-sensitive designs, Antifires provides tailored solutions without compromising fire resistance or aesthetic integrity.
