Kashan Fire Rated Glass & Certified Fire Door Systems by Antifires for Iran’s Building Safety

For architects, specifiers, and building owners in Kashan, ensuring compliance with Iran's stringent fire safety regulations is paramount. Antifires provides certified fire rated glass and complete glazed system solutions that are fully aligned with the Iran National Building Regulation Topic 20 (Fire Protection) and the associated standard ISIRI 11871. These regulations mandate the use of passive fire protection systems in commercial, residential high-rise, and public buildings to contain fire and ensure safe egress. Antifires’ product range, including fire rated glass doors and partitions, is rigorously tested to international benchmarks such as BS 476 Part 22 and BS EN 1634-1, providing verifiable performance data for local building permit applications. By integrating these certified assemblies, Kashan projects can achieve the required fire resistance levels—from EI 30 to EI 120—while maintaining design flexibility. For direct reference to the official regulatory framework, professionals are encouraged to consult the Iranian National Building Regulations published by the Ministry of Roads and Urban Development, which detail the specific fire resistance criteria for various occupancy types and building heights.

Kashan Fire Safety Compliance Aligned with Iran National Building Regulation Topic 20

Compliance with Iran National Building Regulation Topic 20 is a non-negotiable requirement for all new constructions and major renovations in Kashan. This regulation, which aligns with international fire safety principles, demands that building elements maintain their fire-resisting function for a specified duration. Antifires addresses this by offering glazed systems that meet the performance criteria defined under ISIRI 11871, the national standard for fire resistance tests. For Kashan’s growing number of mixed-use developments and high-rise residential towers, the ability to provide certified integrity (E) and insulation (I) ratings is critical.

  • Regulatory Alignment: All Antifires systems are tested to demonstrate compliance with the fire resistance durations (e.g., 60, 90, 120 minutes) specified in Topic 20 for different building classifications.
  • Certified Performance: Products such as the 28mm EI60 panel, which provides 66 minutes of integrity and 64 minutes of insulation, offer documented proof of performance for local authority approvals.
  • Project Documentation: Antifires provides full test reports and certification documentation, enabling seamless integration into the legal compliance framework required for construction permits in Kashan.

Fire Rated Glass Grade Selection for Kashan’s Climate and Thermal Insulation Demands

Kashan’s unique climate, characterized by hot summers and cool winters, places specific demands on building envelope performance. Fire rated glazing must not only provide life safety but also contribute to the building’s thermal comfort without compromising its fire-resistant properties. Antifires’ advanced multi-layer composite fire-resistant glass structures are engineered to meet these dual requirements. For instance, the 21mm FPOS system, which delivers 120 minutes of integrity and 30 minutes of insulation, incorporates intumescent gel layers that activate under high heat while providing a baseline level of thermal resistance under normal conditions.

  • Thermal Performance: The multi-layer design, including options like the 50mm/54mm ultra-high-performance glass, reduces heat transfer, helping to stabilize interior temperatures in Kashan’s extreme weather.
  • Fire Compartmentation: In mixed-use zones such as the historical bazaar or new commercial centers, these systems effectively seal fire compartments, preventing the spread of smoke and flames as validated by tests under BS EN 1364-1.
  • Adapted Solutions: By selecting the appropriate glass composition (e.g., 15mm FPOS for integrity up to 132 minutes), engineers can balance thermal insulation demands with the specific fire hazard classification of the building.

Engineering Project Applications in Kashan’s Heritage Sites and Modern Commercial Zones

The diverse architectural landscape of Kashan—from its UNESCO-listed historic houses to its modern commercial high-rises—requires versatile fire protection solutions. Antifires’ certified systems are engineered to be adaptable, meeting the stringent fire safety demands of both heritage restoration and contemporary construction. For heritage sites, the challenge is to integrate modern fire safety without altering the aesthetic character. Antifires provides fire rated glass doors and windows that can be customized to fit existing historical frames, using slim-profile steel sections and ceramic wool seals to maintain the original visual appearance while providing up to 90 minutes of fire integrity.

  • Heritage Restoration: Systems like the 26mm door glass (89–90 minutes integrity) can be installed within existing timber or steel frames, preserving historical detailing.
  • Modern Commercial Zones: For new office towers and shopping centers, large-span fire rated glass partitions using 50mm/54mm EI120 glass allow for open-plan designs that meet strict compartmentation rules.
  • Industrial & Public Buildings: Factories and public facilities benefit from robust systems like the 10mm FPOS (135 minutes integrity), ensuring safe evacuation routes in high-occupancy scenarios.

Antifires Localized Advantage for Kashan: Certified Supply Chain and Iran-Specific Testing

Antifires offers a distinct localized advantage for Kashan projects by providing a certified supply chain that understands and complies with Iran-specific testing and regulatory requirements. All products are tested in accredited laboratories according to international standards such as BS 476 Part 22 and AS1530.4, ensuring that the performance data is globally recognized and locally accepted. The company’s technical team can provide direct support for interpreting Iran’s Topic 20 requirements and selecting the appropriate fire resistance rating for any application.

  • Certified Supply Chain: From the G.M.S. hollow steel frames to the intumescent fire seals (20mm x 4mm) and ceramic wool (density 210 kg/m³), every component is sourced and tested as part of a complete system.
  • Iran-Specific Testing: Antifires references test conditions that mirror real-world installation scenarios, including ambient temperatures of 27°C–36°C and relative humidity up to 90%, ensuring reliability in Kashan’s environment.
  • Technical Support: Local representatives can assist with system design, anchoring specifications (M6/M8 bolts at 300-600mm spacing), and expansion gap management (3-5mm) to guarantee installation integrity.

Frequently Asked Questions (FAQ)

Yes, Antifires fire rated glass systems are fully designed to comply with the fire resistance requirements of Iran’s National Building Regulation Topic 20. The products are tested according to international standards such as BS 476 Part 22 and BS EN 1634-1, which are recognized by Iranian authorities for demonstrating compliance with the national code. Antifires provides certified test reports that detail the integrity (E) and insulation (I) performance of each glazing assembly, making it straightforward for Kashan developers and architects to secure building permits and pass final fire safety inspections.

For commercial high-rises in Kashan, the required fire resistance rating is typically determined by the building’s height, occupancy, and specific compartmentation strategy as defined in Topic 20. For most fire doors in escape routes and compartment walls, an EI 60 rating (60 minutes of integrity and insulation) is a common minimum standard. However, for buildings exceeding certain height limits or housing critical infrastructure, an EI 120 rating may be mandated. Antifires offers certified solutions across all these ratings, including the 28mm EI60 panel and the 50mm/54mm EI120 system, allowing for precise specification based on the project’s fire engineering design.

Yes, Antifires can provide certified fire rated glass solutions specifically designed for Kashan’s heritage restoration projects. The company offers systems that can be installed within existing historical window frames, using slim-profile G.M.S. hollow steel sections and ceramic wool seals to minimize visual impact. For example, the 26mm door glass system, which provides up to 90 minutes of integrity, can be customized to fit the dimensions and aesthetic requirements of traditional Kashan architecture. This allows project teams to achieve the necessary fire compartmentation without compromising the historical integrity of the building.
