Adhering to Hyderabad Fire Safety Norms Under NBC 2016 & Telangana Building Rules
Hyderabad’s building by-laws, enforced under the Telangana Municipalities Act and HMDA regulations, strictly mandate fire resistance ratings for structural elements. Antifires products are engineered to comply with NBC 2016 Part 4, which specifies fire resistance periods based on building height and occupancy type. For instance, high-rise residential buildings in Jubilee Hills or commercial towers in Raidurgam require glazed assemblies with a minimum of 60 to 120 minutes integrity. Our systems, tested to BS 476 Part 22 and BS EN 1634-1, provide documented performance data that aligns with these local codes.
Key compliance features include:
- Integrity (E): Resistance to flame penetration and hot gas leakage, verified up to 120 minutes.
- Insulation (I): Thermal barrier performance where the unexposed side temperature rise is limited to an average of 140°C, critical for escape routes.
- Frame and Sealant Systems: Use of G.M.S. hollow steel frames with intumescent seals (20mm x 4mm) and ceramic wool (3–6mm, density 210 kg/m³) to prevent heat transfer through edges.
This engineering approach ensures that fire-rated assemblies not only pass the furnace test (with furnace pressure at 0 ±2Pa) but also perform reliably in Hyderabad’s humid climate, where thermal expansion and contraction must be managed through proper expansion gaps (3–5mm filled with ceramic fiber).
Selecting Fire Rated Glass Grades for Hyderabad’s Climate and Structural Design
Selecting the correct fire rated glass grade for Hyderabad projects requires an understanding of both fire performance and environmental factors. The city’s tropical climate, with high relative humidity (43%–90% during testing), demands glass systems that resist thermal shock and maintain optical clarity. Antifires offers a range of certified products tailored for specific applications:

For structural design, consider the following:
- Deflection Management: Maximum deflection toward the furnace can reach 38–152mm; frames must accommodate this movement.
- Installation Parameters: Anchor bolts (M6/M8) at 300–600mm spacing, with fire-rated insulation board (12–15mm) behind frames.
- Glass Behavior: Surface glass cracks at 2–4 minutes, but intumescent gel activates to maintain integrity for the rated duration.
Engineering Project Applications for Hyderabad’s Commercial and Residential Sectors
Hyderabad’s diverse project landscape—from IT parks in Raidurgam to luxury apartments in Jubilee Hills and retail malls in Kukatpally—demands versatile fire-rated glazing solutions. Antifires systems are designed for three primary applications:
- Internal Glazed Partitions: Open-plan offices require clear, non-loadbearing partitions with EI30 to EI60 ratings. Our fire partition solutions use 21mm FPOS (120 min integrity, 30 min insulation) to create safe compartmentation without sacrificing natural light.
- Fire Door Vision Panels: For escape routes in commercial towers, 26mm door glass (89–90 min integrity, 68 min insulation) provides high thermal resistance, ensuring doors remain operable during a fire.
- External Façades: The upcoming Pharma City projects require curtain wall systems with 50–54mm ultra-high-performance glass (EI120) to prevent fire spread between buildings. These assemblies incorporate multi-layer insulated structures with intumescent gel for both thermal and acoustic control.
Each system is engineered to meet the specific pressure and deflection conditions of the test furnace (0 ±2Pa) and is supported by detailed installation manuals for local contractors.
Why Hyderabad Architects and Contractors Trust Antifires for Fire Safety Compliance
Hyderabad architects and contractors choose Antifires because of our proven track record in delivering compliant, high-performance fire safety systems for the Indian market. Key advantages include:
- Localized Technical Support: Dedicated engineers provide on-site installation guidance, ensuring that expansion gaps (3–5mm), ceramic wool placement, and intumescent seal integration meet test specifications.
- Third-Party Certification: All products carry test reports aligned with BS 476 Part 22 and BS EN 1634-1, which are accepted by Hyderabad’s building approval authorities. This reduces project approval risks and ensures liability protection.
- Supply Chain Reliability: With a dedicated supply chain for India, lead times for fire rated glass deliveries to HITEC City or Gachibowli are minimized, supporting tight construction schedules.
- Comprehensive Documentation: Each shipment includes compliance certificates, test data (including furnace thermocouple readings and unexposed surface monitoring), and installation checklists, ensuring full traceability for project audits.
By partnering with Antifires, Hyderabad builders gain a reliable ally in navigating the complex regulatory landscape of Telangana’s fire safety codes.
