Certified Fire Rated Glass Supplier for Dhaka’s Building Compliance Needs

As a certified supplier of fire rated glass in Dhaka, Antifires provides building professionals with glazing systems that fully comply with the Bangladesh National Building Code (BNBC) 2020 and international fire safety standards. Dhaka’s rapid urbanization, particularly in high-density commercial districts like Gulshan, Motijheel, and Banani, has intensified the demand for passive fire protection solutions that meet stringent local fire service inspection protocols. The BNBC 2020 mandates specific fire resistance ratings for egress paths, compartmentation walls, and fire-rated doors and windows, requiring tested assemblies that can withstand fire for 60 to 120 minutes. Antifires’ product portfolio, including integrity-only (E) and combined integrity and insulation (EI) glass systems, is engineered to deliver verified performance under these localized regulations. All assemblies are tested in accordance with BS 476 Part 22 and BS EN 1634-1, ensuring that each product’s fire resistance data is traceable and certifiable for building permit submissions in Dhaka. By integrating fire-rated glazing into new commercial towers, mixed-use developments, and residential high-rises, architects and contractors can achieve both code compliance and enhanced occupant safety. Antifires also provides compliance documentation and technical support to streamline the approval process with Dhaka’s fire service and civil aviation authorities.

BNBC 2020 Compliance Requirements for Fire Rated Glass in Dhaka Commercial Projects

Dhaka’s commercial projects, especially in high-traffic zones like Gulshan and Motijheel, must adhere to BNBC 2020 Chapter 8, which outlines fire resistance requirements for structural elements and compartmentation. For glazed assemblies used in egress corridors and fire-rated walls, the code typically demands a minimum fire resistance rating of 60 minutes (E60) for integrity, with higher ratings up to 120 minutes (EI120) for critical separation barriers. Antifires supplies fire-rated glass systems that have been tested to meet these benchmarks, with certified data showing integrity durations of up to 135 minutes and insulation performance of up to 120 minutes for select multi-layer configurations. The BNBC 2020 also references NFPA 80 for the installation of fire doors and windows, requiring that all framing, seals, and glazing materials be compatible and tested as a complete assembly. Antifires’ systems utilize G.M.S. hollow steel frames, intumescent fire seals (20mm × 4mm), and ceramic wool infills (3mm–6mm, density 210 kg/m³) to ensure that the entire assembly—not just the glass—meets the required fire resistance. For Dhaka-based projects, this means that building owners and contractors can submit test reports and compliance certificates directly to local authorities, reducing approval delays and ensuring that the installed systems will perform as expected during a fire event.

Technical Parameters for Fire Rated Glass Selection in Dhaka’s Humid Climate

Dhaka’s tropical monsoon climate, characterized by high humidity and temperature fluctuations, presents unique challenges for fire-rated glazing systems. In high-rise structures located in Banani, Dhanmondi, and Uttara, the selection of fire-rated glass must account for both thermal performance and environmental durability. Antifires’ fire-rated glass products, such as the 21mm FPOS and 28mm EI60 panels, are constructed with multi-layer tempered glass and intumescent gel interlayers that remain stable under high humidity conditions. The gel layers expand when exposed to fire, forming an insulating barrier that limits temperature rise on the unexposed side to ≤180°C (maximum) and ≤140°C (average) per BS EN 1364-1 test protocols. Additionally, the systems incorporate expansion gaps (3mm–5mm) filled with ceramic fiber, which accommodate thermal movement without compromising the fire seal. For projects requiring compliance with BNBC 2020 Section 8.4 and NFPA 80, Antifires provides detailed technical data sheets that include test conditions such as ambient test temperatures (27°C–36°C) and relative humidity (43%–90%) recorded during certification. This transparency allows Dhaka-based specifiers to verify that the products have been evaluated under conditions representative of local environmental extremes. By choosing systems with proven insulation and radiation control (EW120), architects can also minimize radiant heat transfer through glazed facades, enhancing occupant safety in mixed-use towers where fire compartments adjoin public circulation areas.

Building Application Scenarios for Fire Rated Systems in Dhaka’s Urban Development

Dhaka’s urban development landscape includes a diverse range of building typologies, each requiring tailored fire-rated glazing solutions. In commercial office towers in Gulshan and Motijheel, fire-rated partitions and doors with EI60 to EI120 ratings are essential for creating safe egress paths and compartmenting floor areas. Antifires supplies fire partition solutions that combine 28mm EI60 glass panels with steel framing, achieving integrity of 66 minutes and insulation of 64 minutes—ideal for corridor walls and stairwell enclosures. For residential high-rises in Dhanmondi and Banani, fire doors with 26mm glazed door glass (5mm + 5.5mm gel + 5mm + 5.5mm gel + 5mm) provide integrity up to 90 minutes and insulation up to 68 minutes, meeting the BNBC 2020 requirements for apartment unit separation. In mixed-use developments that include retail, office, and residential zones, 50mm or 54mm ultra-high-performance glass systems offer EI120 ratings, ensuring that fire can be contained for two hours across different occupancy types. Antifires also supports industrial and healthcare projects in Dhaka’s expanding periphery, where fire-rated glass blocks and bricks are used for decorative yet compliant fire barriers. Each application scenario is backed by certified test data and installation guidelines that align with Dhaka’s building permit requirements, enabling architects and contractors to specify with confidence.
