Zanjan Fire Rated Glass & Certified Systems for Iranian Building Code Compliance

Zanjan, a rapidly developing industrial and cultural hub in northwestern Iran, presents unique challenges for fire safety engineering. Compliance with the Iranian National Building Regulations, specifically Topic 20 (Fire Protection), is mandatory for all commercial, residential, and industrial projects in the city. Antifires provides certified fire rated glass, door, and window systems that strictly adhere to these local codes, ensuring that architectural designs meet the highest standards of passive fire protection. The company’s product portfolio is tested against rigorous international benchmarks such as BS 476 Part 22 and BS EN 1634-1, with performance metrics that align with the requirements of the Iranian Fire Department (IFD) and ISIRI 5737 standards.

For specifiers in Zanjan, selecting the correct fire-rated system involves understanding the interplay between local seismic regulations (Standard No. 2800) and fire resistance ratings. Antifires offers a comprehensive range of solutions—from 60-minute fire rated glass for smoke containment to advanced EI120 insulated panels for high-risk zones. All systems are engineered to maintain structural integrity under dynamic loads while providing verified fire performance. For detailed regulatory guidance, professionals can refer to the official Iranian National Building Regulations (INBR) portal for Topic 20 documentation and updates.

Integrating Zanjan’s Seismic Design Requirements with Fire Resistance Compliance

Zanjan is classified as a high-seismicity region under Iranian Standard No. 2800 (Seismic Design of Buildings). This mandates that all passive fire protection systems, including glazed assemblies, must maintain their fire-integrity ratings even when subjected to significant structural movement, deflection, or inter-story drift. Antifires fire rated glass systems are specifically engineered to address this dual requirement. The assemblies utilize G.M.S. hollow steel frames with reinforced anchoring (M8 bolts at 300mm spacing) and 3mm to 5mm expansion gaps filled with ceramic fiber, which allow controlled movement without compromising the fire seal.

During seismic events, the frame and glass must act as a unified system to prevent premature failure. The intumescent gel layers within the glass (e.g., the 10mm FPOS structure: 3mm float glass + 4mm fire gel + 3mm float glass) are designed to remain stable under vibration. Test data from ASTM E119 and AS1530.4 confirm that these systems can withstand dynamic loading while preserving their E (Integrity) and I (Insulation) ratings. For Zanjan’s high-rise residential towers and public buildings, Antifires provides pre-installation load calculations that verify compliance with both Standard No. 2800 and Topic 20, ensuring that the fire-rated envelope remains effective throughout the building’s lifecycle.

Selecting E-Class and EI-Class Fire Rated Glass for Zanjan’s Climate and Industrial Zones

Zanjan’s climate, characterized by cold winters with ambient temperatures as low as -10°C, and its expanding industrial zones, require careful selection of fire rated glass classes. For general smoke containment and evacuation routes in commercial buildings, E 60/30 fire rated glass (Integrity only) is often specified. This glass, tested to BS 476 Part 22 for 60-minute integrity, provides a cost-effective barrier against flame and hot gas penetration. It is ideal for internal partitions and vision panels where thermal insulation is not the primary concern.

For industrial applications—such as factory partitions in Zanjan’s petrochemical and manufacturing sectors—EI 60 (Integrity + Insulation) glass is the recommended standard. The 28mm EI60 panel (6mm + 5.5mm gel + 5mm + 5.5mm gel + 6mm) delivers 66 minutes of integrity and 64 minutes of insulation, effectively preventing heat transfer even when exterior temperatures drop significantly. The table below summarizes the recommended glass types for different Zanjan project scenarios:

Project Type Recommended Glass Class Key Performance
Commercial Offices E 60 Smoke containment, 60-min integrity
Industrial Kitchens EI 60 Thermal insulation, high humidity resistance
Factory Partitions EI 60 or EI 120 Heat barrier, structural stability

All products are tested per ISIRI 5737, ensuring stable performance in Zanjan’s variable climate conditions.

Meeting Fire Safety Demands in Zanjan’s Historic Bazaars and Modern Petrochemical Facilities

Zanjan’s architectural landscape presents two distinct fire safety challenges: the preservation of the UNESCO-listed historic bazaar complex and the protection of modern petrochemical facilities. For the bazaar, which features narrow corridors and traditional timber and masonry construction, Antifires provides slim-profile fire rated glass doors that deliver 60-minute integrity (E60) without compromising the heritage aesthetic. These systems use 26mm glazed door glass (5mm + 5.5mm gel + 5mm + 5.5mm gel + 5mm), which achieves 89–90 minutes of integrity and 68 minutes of insulation, allowing for discrete integration into existing wooden frames. The ceramic wool seals (3mm, density 210 kg/m³) ensure a tight fit while maintaining the visual transparency required for retail visibility.

In contrast, Zanjan’s growing petrochemical sector near the city requires explosion-resistant fire windows that meet NFPA 68 (Guidelines for Explosion Protection by Deflagration Venting) standards. These assemblies utilize the 50mm ultra-high-performance glass (multi-layer insulated fire-resistant structure), which provides EI120 ratings—120 minutes of both integrity and insulation. The system is designed to withstand rapid pressure increases while maintaining its fire barrier function. For these high-risk zones, Antifires also incorporates intumescent fire seals (20mm × 4mm) that expand under heat to seal gaps, preventing the passage of flames and toxic gases. This dual compliance with heritage preservation and industrial safety standards makes Antifires the preferred choice for Zanjan’s diverse project requirements.
