Surabaya Building Fire Safety Codes – Adapting to SNI 1727:2020 and Local Enforcement
Surabaya’s enforcement of SNI 1727:2020 requires fire-rated assemblies to perform under both thermal stress and seismic displacement. This is particularly critical in high-rise structures along Jalan Basuki Rahmat and industrial zones in Rungkut, where compartmentation must remain intact during a fire event. Antifires’ fire rated glass systems are tested to meet 60–120 minute integrity (E) ratings under conditions that simulate Indonesian loading scenarios, including lateral movement from seismic events. The assemblies utilize G.M.S. hollow steel frames with ceramic wool (3–6 mm, density 210 kg/m³) and intumescent fire seals (20 mm × 4 mm) to maintain gap integrity during deflection. Test data confirms that these systems withstand furnace pressures of 0 ±2 Pa and ambient temperatures of 27°C–36°C, mirroring Surabaya’s tropical conditions. For stairwell enclosures and fire-rated corridors, specifiers can rely on 90-minute fire rated glass solutions that have demonstrated sustained performance in third-party lab evaluations. This localized adaptation ensures that every installation passes the rigorous inspections required by the Surabaya Fire Brigade, reducing project delays and liability.
Fire Rated Glass Classification for Surabaya’s Tropical Climate – EI and EW Performance Data
Surabaya’s tropical climate—with average temperatures of 30°C and relative humidity often exceeding 80%—demands fire rated glass that resists thermal stress failure while maintaining fire performance. Antifires supplies EI-class (insulation) and EW-class (radiation control) glass systems engineered for these conditions. A typical configuration includes 6 mm tempered glass laminated with a 0.76 mm intumescent interlayer, which activates under fire exposure to form an insulating char. Test data from BS EN 1364-1 confirms that such assemblies achieve up to 120 minutes of integrity without delamination or thermal shock, even when exposed to rapid temperature rises. For projects requiring both integrity and insulation, the 28 mm EI60 panel (6 mm + 5.5 mm gel + 5 mm + 5.5 mm gel + 6 mm) delivers 66 minutes of integrity and 64 minutes of insulation, as verified by furnace tests using Type K thermocouples (9–12 channels). The table below summarizes key performance classifications for Surabaya’s climate:
| Classification | Integrity (E) | Insulation (I) | Typical Application |
| EW120 | 120 min | Radiation control | Atrium glazing |
| EI60 | 66 min | 64 min | Stairwell enclosures |
| EI30 | 30 min | 30 min | Internal partitions |
These ratings ensure that fire partition solutions remain stable under Surabaya’s high-humidity conditions, preventing interlayer degradation over the building’s lifecycle.
Surabaya Project Applications – Fire Rated Glass for Hotels, Malls, and Petrochemical Facilities
Surabaya’s diverse project landscape—from hotel refurbishments in Gubeng to petrochemical control rooms in Tanjung Perak—requires fire rated glass systems tailored to specific occupancy risks. For hotel corridors, 60-minute fire doors with glazed inserts provide egress protection while maintaining visibility for wayfinding. These assemblies integrate with existing steel frames using M6/M8 anchor bolts at 300–600 mm spacing and 3–5 mm expansion gaps filled with ceramic fiber, ensuring seismic compatibility. In petrochemical facilities, where radiant heat poses a secondary hazard, EW120-rated glass (120 minutes integrity with radiation control) is installed in control room vision panels. Test data from BS 476 Part 22 confirms that such systems limit heat flux to safe levels, protecting operators during a fire event. For mall atria and public assembly areas, 26 mm door glass (5 mm + 5.5 mm gel + 5 mm + 5.5 mm gel + 5 mm) achieves 89–90 minutes of integrity and 68 minutes of insulation, as verified by furnace tests with 10–55 thermocouples on the unexposed surface. Antifires provides pre-engineered fire door systems that meet the specific load and fire-resistance requirements of each Surabaya project, reducing on-site customization and inspection risks.
Why Surabaya Specifiers Choose Antifires – Local Warehousing and SNI-Certified Testing
Specifiers in Surabaya choose Antifires for a combination of local logistics and verified compliance. Our distribution hub near Benowo maintains stock of standard fire rated glass sizes, enabling 3-day delivery for urgent projects. Each batch is supplied with SNI compliance certificates and third-party test reports from Indonesian accredited laboratories, ensuring that every installation meets the documentation requirements of local fire brigade inspections. For projects requiring on-site technical guidance, Antifires provides installation supervision to verify that frames are anchored correctly with M6/M8 bolts at 300–600 mm spacing and that ceramic wool (3–6 mm) is properly packed in expansion joints. This reduces the risk of inspection failures due to improper gap filling or sealant application. Additionally, our test data—including furnace pressure control at 0 ±2 Pa and ambient temperature monitoring between 27°C and 36°C—directly correlates with Surabaya’s environmental conditions, providing confidence in real-world performance. By integrating local warehousing with certified testing, Antifires eliminates the logistical and compliance barriers that often delay fire-rated glazing installations in Indonesia’s second-largest city.
