Meeting Khorramabad’s Fire Safety Codes Under Iran’s National Building Regulation Section 20
Khorramabad’s adherence to Iran’s National Building Regulation Section 20 requires fire-resistant barriers in all high-occupancy structures, including commercial complexes near the Falak-ol-Aflak Castle and new developments in the city center. Antifires fire rated glass systems are tested to BS EN 1364-1: 1999 and BS 476 Part 22: 1987, ensuring compliance with the Iran Fire Department’s mandatory 60-minute fire resistance ratings for egress routes. These standards evaluate both integrity (E)—resistance to flame penetration—and insulation (I)—thermal barrier performance—critical for protecting evacuation paths in multi-story buildings.
For Khorramabad’s projects, the use of EI60-rated glazing is common for stairwells and corridor partitions, where average temperature rise on the unexposed side must not exceed 140°C. Antifires’ 28mm EI60 panels, for example, demonstrate integrity for 66 minutes and insulation for 64 minutes under furnace test conditions, as verified by Type K thermocouples monitoring 10–55 channels. This data aligns with Section 20’s requirement for materials that prevent fire spread for at least 60 minutes, a standard enforced by local building inspectors. Contractors can reference these certified results to streamline approvals from the Khorramabad Municipality.
Additionally, the framing systems incorporate G.M.S. hollow steel sections with 3mm–5mm expansion gaps filled with ceramic fiber, accommodating thermal movement during fire exposure. This design is particularly relevant for Khorramabad’s seismic zone, where flexible joints prevent glass failure during earthquakes. By specifying 60-minute fire rated glass with documented test reports, building owners ensure alignment with both national regulations and local enforcement practices.
Selecting EI-Class Fire Rated Glass for Khorramabad’s Climate and Thermal Insulation Demands
Khorramabad’s climate, characterized by hot summers and cool winters, demands fire rated glass that provides thermal insulation without compromising fire safety. Antifires’ EI-class glazing addresses this through multi-layer composite structures, such as the 21mm FPOS glass, which combines tempered glass layers with intumescent gel. This design achieves integrity for 120 minutes and insulation for 30 minutes, ensuring that unexposed side temperatures remain below the 180°C maximum rise threshold. For projects requiring extended thermal protection, the 50mm EI120 glass offers insulation up to 120 minutes, ideal for exterior partitions in Khorramabad’s mixed-use developments.
The thermal performance of these systems is validated under controlled test conditions, including ambient temperatures of 27°C–36°C and relative humidity of 43%–90%. The intumescent gel layer expands when exposed to heat, forming a char that blocks radiant heat transfer—a critical feature for maintaining comfort in buildings near the Gerdab Sangi historic area. For residential high-rises, EI30-rated glass is often sufficient for internal partitions, while EI60 or EI120 is specified for stairwells and fire doors. Contractors can select from options like the 26mm door glass, which provides 68 minutes of insulation, balancing safety with energy efficiency.
To further enhance thermal performance, Antifires frames use ceramic wool (density 210 kg/m³) and intumescent fire seals (20mm × 4mm) to prevent heat leakage at joints. This system is tested to BS EN 1634-1: 2008, ensuring that the entire assembly—glass, frame, and seals—meets insulation standards. For Khorramabad’s healthcare campus, where temperature control is vital, specifying 90-minute fire rated glass with verified insulation data provides reliable protection against both fire and thermal bridging.
Fire Rated Glass Applications in Khorramabad’s Mixed-Use Developments and Heritage-Adjacent Projects
Khorramabad’s urban renewal projects, including new residential towers near the Gerdab Sangi historic area, require fire rated glass that balances safety with unobstructed sightlines. Antifires fire windows and doors are designed for lobbies, stairwells, and partition walls in mixed-use buildings, providing up to 120-minute integrity without blocking views of the Zagros Mountains. For heritage-adjacent developments, the 15mm FPOS glass offers integrity up to 132 minutes and insulation for 33 minutes, ensuring compliance with Section 20 while maintaining architectural transparency.
In commercial complexes near the Falak-ol-Aflak Castle, glazed partitions with EI60 ratings are specified for corridor separation, preventing fire spread without compromising natural light. The 10mm FPOS glass, with 135 minutes of integrity, is suitable for high-traffic areas where prolonged evacuation time is required. For door assemblies, the 26mm door glass achieves 89–90 minutes of integrity and 68 minutes of insulation, tested to BS EN 1634-1: 2014. These systems use M6/M8 anchor bolts spaced 300–600mm apart, ensuring stability in seismic events as per Iranian Code 2800.
For projects requiring enhanced radiation control, EW120-rated glass limits radiant heat transmission while maintaining visibility, ideal for atriums and entrance lobbies. The 21mm FPOS glass, with 120 minutes of integrity, is often used in stairwells to provide safe egress routes. Contractors can specify fire partition solutions that integrate with existing steel or concrete structures, using 12mm–15mm fire-rated insulation boards to seal gaps. This approach ensures that Khorramabad’s mixed-use developments meet both aesthetic goals and rigorous fire safety standards.
Why Antifires Is the Preferred Fire Rated Glass Partner for Khorramabad’s Building Contractors
Antifires is the preferred partner for Khorramabad’s building contractors due to its comprehensive localized support, including Farsi-language technical documentation such as EN 1364-1 test certificates and Section 20 compliance letters. This documentation streamlines approval processes with the Khorramabad Municipality’s building department, reducing administrative delays for projects like the city’s new healthcare campus. Additionally, Antifires provides on-site engineering support for installation in seismic retrofits, ensuring that fire rated glass assemblies are correctly integrated with flexible framing systems.
The company’s products are tested to global standards, including ASTM E119 and AS1530.4, providing contractors with verifiable performance data. For example, the 28mm EI60 panel demonstrates 66 minutes of integrity and 64 minutes of insulation, while the 50mm EI120 glass achieves 120 minutes for both parameters. These ratings are backed by furnace test data using 9–12 Type K thermocouples and up to 55 unexposed surface sensors, ensuring accuracy. Contractors can request fire door systems with pre-assembled frames and intumescent seals, reducing on-site installation time.
Antifires also offers training for local installers on proper anchoring (M6/M8 bolts at 300–600mm spacing) and expansion gap management (3mm–5mm with ceramic fiber). This hands-on support minimizes errors in seismic zones, where deflection of up to 152mm toward the furnace must be accommodated. By combining certified products with localized expertise, Antifires ensures that Khorramabad’s contractors meet both safety standards and project deadlines, making it a trusted resource for the region’s evolving construction landscape.
