Fire Safety Compliance for Hyderabad Buildings Under Pakistan Building Code 2021
Hyderabad’s building sector must navigate the specific fire safety requirements outlined in the Pakistan Building Code 2021 Section 7, which directly addresses the use of fire-resistant glazing in critical areas such as stairwell enclosures, corridor partitions, and fire-rated doors. Local municipal enforcement in Hyderabad requires that all glazed elements in these zones provide verified integrity and, where specified, thermal insulation. Antifires addresses this with a portfolio of fire rated glass systems tested to BS 476 Part 22 for integrity (E) and BS EN 1364-1 for loadbearing performance. For typical Hyderabad commercial projects, EI 60 rated assemblies are commonly specified for compartment walls, while EI 30 solutions are suitable for vision panels in escape routes. The table below outlines recommended ratings based on common application scenarios in Hyderabad:
| Application | Required Rating (PBC 2021) | Antifires Solution |
| Fire Door Vision Panels | E 60 / EI 30 | 10mm FPOS (Integrity 135 min) |
| Compartment Walls | EI 60 | 28mm EI60 Panel (Integrity 66 min, Insulation 64 min) |
| High-Traffic Escape Routes | EI 120 | 50mm EI120 (Integrity 120 min, Insulation 120 min) |
All systems are installed using G.M.S. hollow steel frames with intumescent seals and ceramic wool, ensuring compliance with local fire officer inspections.
Selecting Fire Rated Glass Grades for Hyderabad’s Climate and Structural Loads
The climatic conditions in Hyderabad, characterized by high humidity and significant temperature fluctuations, impose specific demands on fire rated glass performance. Standard float glass assemblies may suffer from thermal stress or interlayer degradation over time. Antifires addresses these challenges by supplying laminated fire rated glass with UV-stable intumescent interlayers, tested under BS EN 1634-1 for thermal shock resistance. For door and window assemblies in the Sindh region, the 15mm FPOS (Integrity up to 132 min, Insulation 33–34 min) and 21mm FPOS (Integrity 120 min, Insulation 30 min) are recommended. These thicknesses provide structural stability against wind loads while maintaining optical clarity. The glass construction—multi-layer tempered glass with intumescent gel—ensures that the interlayer reacts uniformly under fire conditions, forming a rigid insulating barrier. For projects requiring higher insulation, the 26mm door glass (Integrity 89–90 min, Insulation 68 min) offers superior thermal performance. The table below compares key grades suitable for Hyderabad’s climate:
| Glass Grade | Thickness | Integrity (min) | Insulation (min) | Ideal Use |
| EI 60 | 28mm | 66 | 64 | Windows & Doors |
| EI 90 | 26mm | 89–90 | 68 | Partitions |
| EI 120 | 50mm | 120 | 120 | High-Security Zones |
These systems are installed with a 3–5mm expansion gap filled with ceramic fiber to accommodate thermal movement.
Hyderabad Engineering Applications in Mixed-Use Plazas and Healthcare Facilities
Hyderabad’s growing infrastructure includes mixed-use plazas in Latifabad and healthcare expansions in Qasimabad, both requiring robust passive fire protection. For these high-traffic zones, Antifires supplies fire rated glass systems that meet the rigorous demands of local fire officer inspections and insurance requirements for occupancy certificates. In commercial plazas, 60-minute fire doors and windows (EI 60) are commonly specified for corridor partitions and stairwell enclosures, ensuring safe egress during a fire event. For healthcare facilities, where patient mobility may be limited, 120-minute rated assemblies (EI 120) provide extended protection, allowing for staged evacuation. The 28mm EI60 panel (Integrity 66 min, Insulation 64 min) is ideal for vision panels in hospital doors, while the 50mm EI120 (Integrity 120 min, Insulation 120 min) is suitable for compartment walls separating critical care units. Antifires’ systems are installed with G.M.S. hollow steel frames and ceramic wool seals, ensuring compliance with BS 476 Part 22 and BS EN 1634-1. This level of certification streamlines the approval process with Hyderabad’s municipal authorities, reducing project delays.
