Navigating Ulsan’s Fire Safety Requirements Under the Korean Building Code (KBC) 2023
Ulsan’s status as a petrochemical and heavy industrial powerhouse means that building projects—from refinery control rooms to high-rise logistics offices—must adhere to the Korean Building Code (KBC) 2023 and its specific provisions for fire-resistant glazing. The KBC requires that all glazed partitions, doors, and windows used in evacuation routes and fire compartments achieve a minimum fire resistance rating verified by KS F 2265-1 testing. This standard evaluates both integrity (E) and insulation (I) performance under controlled furnace conditions, with Type K thermocouples monitoring unexposed surface temperatures. For Ulsan’s high-rise structures, which often feature open-plan layouts, the code mandates that fire-rated glass systems maintain compartmentation integrity for at least 60 minutes, aligning with the EI60 classification. Antifires’ 60 minute fire rated glass systems are specifically designed to meet these thresholds, utilizing multi-layer laminated structures with intumescent interlayers that expand under heat to block flame and smoke propagation. By integrating these certified assemblies, Ulsan engineers can satisfy MOLIT’s performance-based design criteria while ensuring that escape routes remain tenable during a fire event.
Selecting Fire Rated Glass Grades for Ulsan’s Petrochemical and Port Environments
Operating in Ulsan’s coastal industrial zones—such as the Onsan and Mipo complexes—presents unique challenges, including corrosive salt air, high ambient temperatures, and potential blast overpressure from refinery operations. For these environments, selecting the appropriate fire rated glass grade is critical. EI-class (integrity and insulation) glass, such as the 28mm EI60 panel (which achieves 66 minutes of integrity and 64 minutes of insulation per KS F 2265-1), is ideal for control rooms and administrative buildings where thermal protection is paramount. In contrast, EW-class (integrity and radiation control) glass is better suited for perimeter glazing in storage areas where radiant heat must be limited but full insulation is not required. The table below summarizes key performance characteristics for typical Ulsan applications:
| Glass Grade | Fire Resistance Rating | Typical Application |
| EI60 | Integrity 66 min; Insulation 64 min | Control rooms, office partitions |
| EW120 | Integrity 120 min; Radiation control | Warehouse perimeter glazing |
| E120 | Integrity 120 min | Stairwell enclosures, escape routes |
Additionally, laminated glass options with multiple gel interlayers (e.g., 26mm door glass with integrity up to 90 minutes) provide enhanced resistance to thermal shock and blast overpressure, making them suitable for refinery control centers where both fire and explosion hazards exist.
Fire Protection Demands in Ulsan’s Shipbuilding Factories and Logistics Warehouses
Ulsan’s shipbuilding facilities, including those operated by Hyundai Heavy Industries, and large-scale logistics warehouses require fire protection strategies that address vast, open floor areas and high occupant densities. The Korean Industrial Safety and Health Act (KISHA) mandates that fire windows and doors in such environments prevent flame spread across compartment boundaries while integrating seamlessly with active systems like automatic fire shutters and smoke exhaust. Antifires’ glazed systems are designed to meet these demands, offering fire resistance ratings of 60 to 120 minutes per KS F 2265-1. For instance, a 21mm FPOS glass panel (integrity 120 minutes, insulation 30 minutes) can be installed in warehouse partition walls to maintain compartmentation without obstructing visibility for forklift operators and logistics personnel. In shipbuilding factories, where welding sparks and hot work are common, the glass’s ability to withstand thermal shock—validated by furnace tests with ambient temperatures ranging from 27°C to 36°C—ensures reliable performance under extreme conditions. Furthermore, these systems can be integrated with intumescent seals (20mm × 4mm) and ceramic wool packing (3mm to 6mm) to maintain airtightness, supporting the smoke control strategies required by KISHA for safe evacuation in heavy manufacturing settings.
Why Ulsan Engineers Trust Antifires for Certified Fire Rated Partition Systems
Ulsan’s engineering professionals increasingly turn to Antifires for fire rated partition systems because of the company’s commitment to certified performance and localized support. Every glazing assembly is factory-tested under conditions that mirror Ulsan Fire Department inspection protocols, including furnace pressure control (0 ±2 Pa after 5 minutes) and thermocouple monitoring (9 to 12 channels for furnace, 10 to 55 for unexposed surfaces). The 120 minute fire rated glass systems, for example, are pre-assembled in G.M.S. hollow steel frames with fire-rated insulation boards (12mm to 15mm), reducing on-site installation time by up to 20%. This efficiency is critical for projects in Ulsan’s Mipo and Onsan industrial complexes, where minimizing downtime is a priority. Additionally, Antifires provides comprehensive documentation for KBC compliance, including test certificates and installation guidelines, ensuring that building owners and contractors can confidently pass local inspections. The use of M6/M8 anchor bolts spaced at 300mm to 600mm intervals, combined with ceramic fiber-filled expansion gaps (3mm to 5mm), guarantees structural stability and fire resistance, even under maximum deflection conditions of up to 152mm toward the furnace.
