Barura Fire Safety Compliance with BNBC 2020 and BS 476 Standards
Barura’s construction sector must align with the Bangladesh National Building Code (BNBC 2020), which enforces strict fire safety measures for all building types. This code mandates the use of fire-rated materials in escape routes, stairwell enclosures, and compartment walls. The primary testing standards referenced for glazing are BS 476 Part 22: 1987 and BS EN 1364-1: 1999, which evaluate the fire resistance of non-loadbearing elements. For Barura, compliance means that any fire rated glass installed must demonstrate verified performance under these specific test conditions.
The BNBC requires that fire-resistant glazing in critical areas, such as fire exits and lobby partitions, maintain Integrity (E) for a minimum duration, often 60 or 90 minutes, depending on the building’s occupancy and height. Antifires’ product range, including 6mm E90 glass and 10mm FPOS systems, has been tested to these standards. The 10mm FPOS, for instance, achieves an integrity of 135 minutes under BS 476 Part 22, far exceeding typical local requirements. This ensures that in the event of a fire, the glazing prevents flame and hot gas penetration, maintaining compartmentation. By selecting products with documented BNBC-compliant test reports, Barura developers can streamline approval processes and enhance building safety.
Selecting Fire Rated Glass Integrity and Insulation Ratings for Barura Climate
Selecting the appropriate fire rated glass for Barura requires a careful evaluation of Integrity (E) and Insulation (I) ratings, especially given the region’s humid subtropical climate. Integrity-only (E) glass, such as the 6mm E90 type, prevents flame passage but allows heat radiation. In contrast, Insulation (EI) glass limits temperature rise on the unexposed side to a maximum average of 140°C and a peak of 180°C, as defined in BS EN 1363-1. For Barura’s high-humidity environment, EI-rated products like the 28mm EI60 panel (with integrity of 66 minutes and insulation of 64 minutes) are ideal because they incorporate intumescent gel layers that resist delamination and moisture ingress.
The table below summarizes key performance characteristics for common ratings relevant to Barura’s climate:
| Rating |

For Barura’s climate, EI60 and EI120 glass offer superior thermal performance, reducing the risk of fire spread through radiant heat. Antifires’ 60 minute fire rated glass systems are engineered with sealed edges and ceramic wool framing (density 210 kg/m³) to prevent moisture penetration, ensuring long-term reliability in Barura’s monsoon seasons.
Fire Rated Glass Applications in Barura Hospitals, Hotels and Market Complexes
Barura’s expanding healthcare, hospitality, and commercial sectors demand specialized fire-rated glazing solutions. In hospitals, patient safety and compartmentation are paramount. Fire-resistant partitions and doors must achieve at least 60-minute integrity and insulation (EI60) to protect evacuation routes and critical care areas. Antifires’ 26mm door glass (integrity 89–90 min, insulation 68 min) is ideal for such applications, as it provides extended protection while allowing natural light into corridors. The glass is installed in G.M.S. hollow steel frames with intumescent fire seals (20mm × 4mm) to ensure a tight barrier against smoke and flames.
For hotels and market complexes, multi-story buildings require 30 to 120-minute fire ratings depending on floor area and occupancy load. In Barura’s retail centers, EI120 rated glass, such as the 50mm or 54mm ultra-high-performance panels, is used for fire compartment walls between shops and common areas. These systems undergo rigorous testing under BS EN 1364-1: 2015, with furnace thermocouples (Type K, 9–12 channels) monitoring temperatures to ensure compliance. The maximum deflection recorded during tests is up to 152mm toward the furnace, indicating structural resilience. By integrating these certified systems, Barura’s commercial buildings meet BNBC requirements while maintaining aesthetic transparency.
Antifires Localized Support and BNBC-Certified Product Range for Barura
Antifires offers direct factory support for Barura projects, ensuring seamless integration of BNBC-compliant fire rated glass and door systems. The product range includes E60, E90, E120 (integrity only) and EI30, EI60, EI120 (integrity + insulation) ratings, all tested under BS 476 Part 22 and BS EN 1634-1. For Barura’s construction schedules, Antifires provides fast lead times for custom-sized units, with frames fabricated from G.M.S. hollow steel sections and fixed using M6/M8 anchor bolts at 300–600mm spacing. The expansion gap (3mm–5mm) is filled with ceramic fiber to accommodate thermal movement.
Technical consultation is a key part of Antifires’ localized service. Engineers can advise on the correct selection of fire partition solutions based on building type and occupancy. For example, in Barura’s schools or community centers, 10mm FPOS glass (integrity 135 min) may be specified for high-traffic areas. Antifires also supplies compliance documentation, including test certificates and material declarations, which are accepted by local Barura building authorities. This end-to-end support—from product selection to installation guidance—ensures that Barura’s construction projects achieve the highest standards of passive fire protection without delays.
