Certified Fire Rated Glass Solutions for Tehran’s Building Compliance and Safety

Tehran’s rapidly expanding urban landscape demands a rigorous approach to passive fire protection, particularly for high-rise commercial towers and dense residential complexes. Compliance with the Iran National Building Code (Mabhas 3: Hafezat) and directives from the Tehran Fire Department is mandatory for all new developments and major renovations. Antifires provides certified fire rated glass and glazed systems engineered to meet these localized regulatory requirements, including the fire resistance criteria outlined in Iranian Standard ISIRI 4684. These products are designed to maintain compartmentation integrity during a fire event, ensuring safe egress for occupants and facilitating effective firefighting operations. By integrating advanced intumescent gel technology within multi-layer glass structures, these systems achieve verified performance levels that align with both international benchmarks (BS EN 1634-1, ASTM E119) and Iran’s specific national codes. For project consultants and developers in Tehran, selecting certified fire-rated glazing is not merely a regulatory obligation but a fundamental component of life safety and property protection. Antifires’ solutions are backed by documented test reports and localized technical documentation, providing the necessary evidence for approval by local authorities. For further reference on national fire safety frameworks, developers can consult the official Iranian government portal for building regulations.

Compliance with Tehran’s Fire Safety Codes and National Building Regulations

Tehran’s construction sector operates under the strict enforcement of Mabhas 3 of the Iran National Building Code, which mandates specific fire resistance ratings for structural elements, exit routes, and facade systems. Antifires addresses these requirements with products tested to BS 476 Part 22 and BS EN 1634-1, ensuring compliance with the performance criteria referenced in ISIRI 4684. For high-rise buildings in central districts, the code typically requires integrity (E) and insulation (I) ratings for glazed assemblies in stairwells and fire-rated corridors. Antifires’ systems, such as the 28mm EI60 panel (Integrity 66 min, Insulation 64 min) and 21mm FPOS (Integrity 120 min, Insulation 30 min), provide documented evidence of meeting these thresholds. The localized compliance process involves submitting third-party test reports to the Tehran Fire Department and the municipality’s building safety inspection unit. Antifires supports this process by providing complete technical files, including furnace test data with Type K thermocouples and unexposed surface monitoring, ensuring transparent verification of fire performance. This approach minimizes approval delays and ensures that the installed systems meet the rigorous standards required for occupancy permits.

Selecting Fire Rated Glass Grades for Tehran’s Climate and Seismic Conditions

Tehran’s location in a high-seismic zone and its experience of significant temperature fluctuations (from near-freezing winters to hot summers) impose unique demands on fire-rated glazing. Antifires offers EI-class fire rated glass (EI30, EI60, EI120) that integrates structural resilience with thermal performance. For example, the 26mm glazed door glass (Integrity 89–90 min, Insulation 68 min) and 50mm/54mm ultra-high-performance glass (Integrity 120 min, Insulation up to 120 min) are constructed with multi-layer tempered glass and intumescent gels that expand under heat, providing both fire resistance and impact resistance. These systems are tested under conditions simulating realistic fire scenarios, with furnace pressures maintained at 0 ±2Pa and ambient temperatures between 27°C and 36°C. The laminated structure ensures that even if the outer pane cracks (typically at 2–4 minutes), the inner layers remain intact, preventing flame penetration and maintaining compartmentation. For seismic resilience, the framing systems use G.M.S. hollow steel sections with M6/M8 anchor bolts spaced at 300–600mm, accommodating building movement without compromising the glazing’s fire integrity. This combination of thermal and structural performance makes Antifires solutions suitable for Tehran’s demanding environmental conditions.

Application of Fire Rated Systems in Tehran’s Commercial and Residential Projects

Antifires’ fire-rated systems are deployed across a wide range of project types in Tehran, from the commercial towers of District 6 (including the Afra Tower and Saman Complex) to the rapidly developing residential areas of District 22. In commercial high-rises, fire partition solutions are essential for stairwell enclosures, elevator lobbies, and curtain wall spandrels, where EI60 or EI120 ratings are typically required. For healthcare facilities and government buildings, the 26mm door glass system provides the necessary insulation (68 min) to protect patients and sensitive equipment from radiant heat. In residential projects, E90 or E120 integrity-only glass is often specified for corridor partitions and fire doors, ensuring safe egress without excessive cost. Antifires offers customized framing and glazing configurations, including expansion gaps of 3–5mm filled with ceramic fiber, to accommodate building movement and thermal expansion. The systems are designed for seamless integration with existing fire-rated walls and doors, providing complete compartmentation solutions. Each installation is supported by detailed shop drawings and compliance documentation, ensuring that the final assembly meets the specific requirements of the Tehran Municipality’s building safety inspection.

Why Tehran Developers Trust Antifires for Certified Fire Protection Products

Tehran developers and contractors choose Antifires for the company’s documented compliance with Iran’s national fire standards, backed by third-party test reports from accredited laboratories. Unlike generic products, Antifires provides localized engineering support that assists with project-specific approvals from the Tehran Fire Department and the Municipality’s Building Safety Division. This includes preparing compliance files that reference test data from standards such as BS EN 1364-1 and AS1530.4, ensuring that every installation meets the required fire resistance duration. The company’s Tehran-based stock ensures rapid delivery, reducing project delays and logistical risks. Furthermore, Antifires’ technical team offers on-site guidance for installation, including proper use of ceramic wool (3–6mm, density 210 kg/m³) and intumescent fire seals (20mm × 4mm), which are critical for maintaining system integrity. This comprehensive support reduces compliance risk, simplifies the inspection process, and ensures that the final project passes final safety audits without costly rework. For developers seeking reliable, certified fire protection, Antifires represents a trusted partner with a proven track record in the Tehran market.

Frequently Asked Questions (FAQ)

Yes, Antifires fire rated glass is designed to meet the specific fire resistance requirements of the Tehran Fire Department and the Iran National Building Code (Mabhas 3: Hafezat). The products are tested to international standards such as BS 476 Part 22 and BS EN 1634-1, which are referenced in Iranian Standard ISIRI 4684. This includes documented performance for integrity (E) and insulation (I) ratings, such as EI60 and EI120, which are commonly mandated for exit routes and high-rise facades. Antifires provides third-party test reports and localized technical documentation that can be submitted to local authorities for approval, ensuring full compliance with Tehran’s building safety regulations.

For commercial high-rise projects in Tehran’s central districts (such as District 6 and District 12), the most commonly required fire resistance durations are EI60 (60 minutes integrity and insulation) and EI120 (120 minutes integrity and insulation). These ratings are specified for stairwell enclosures, elevator lobbies, and curtain wall spandrels to ensure safe egress and compartmentation. In some cases, E90 or E120 integrity-only glass may be acceptable for non-insulated partitions, depending on the building’s fire safety strategy and the approval of the Tehran Fire Department. Antifires offers certified products that meet these ratings, including 28mm EI60 panels and 50mm/54mm EI120 systems.
