Adapting Fire Rated Glass to Cilegon’s SNI 03-1726-2019 Seismic and Fire Resistance Codes
Cilegon’s location in a seismically active region requires fire rated glazing to perform under dual threats: fire exposure and earthquake-induced structural movement. The SNI 03-1726-2019 standard mandates that building elements in industrial zones must maintain their fire resistance ratings after experiencing design-level seismic displacements. This is particularly critical for glazed partitions in control rooms and egress corridors within the Krakatau Industrial Estate. Antifires’ EI60 and EI120 glass assemblies are engineered to address this challenge. The systems incorporate multi-layer tempered glass with intumescent gels that expand under heat, creating an insulating barrier. To ensure seismic resilience, the glazing is installed within G.M.S. hollow steel frames using ceramic wool (density 210 kg/m³) and expansion gaps of 3mm to 5mm. These components allow the frame to flex without transferring destructive forces to the glass, preventing spalling or catastrophic failure. During testing per BS EN 1364-1, these assemblies have demonstrated the ability to withstand furnace pressures of 0 ±2Pa while maintaining integrity. For Cilegon’s industrial facilities, this means the glazing can resist both the thermal shock of a fire and the lateral forces of an earthquake, providing a reliable barrier that supports safe evacuation and property protection. The use of intumescent fire seals (20mm × 4mm) further enhances performance by sealing gaps that could compromise the compartment.
Selecting Fire Rated Glass Integrity and Insulation Classes for Cilegon’s Industrial Environment
Selecting the appropriate fire resistance class is a critical decision for Cilegon’s industrial projects, particularly for petrochemical plants where fire loads are high. Local building permits increasingly require certified reaction-to-fire class B per SNI 03-1735-2000, which aligns with international classifications. The two primary ratings to consider are Integrity (E) and Insulation (I). Integrity-only glass (e.g., E60, E90) prevents flames and hot gases from passing through but allows significant heat transfer. Insulation-rated glass (e.g., EI30, EI60, EI120) limits the temperature rise on the unexposed side to an average of ≤140°C and a maximum of ≤180°C, protecting adjacent materials and personnel. For Cilegon’s control rooms, where sensitive electronics and operators are present, an EI60 or EI120 rating is recommended. The table below summarizes the typical performance of Antifires’ certified products for industrial applications:

Fire Rated Glass Applications Across Cilegon’s Heavy Industry and Logistics Infrastructure
In Cilegon’s heavy industry and logistics sectors, fire rated glass serves multiple critical roles beyond simple compartmentation. For petrochemical plant control rooms, glazed partitions must provide both fire resistance and visibility for monitoring operations. Antifires’ 26mm door glass (5mm + 5.5mm gel + 5mm + 5.5mm gel + 5mm) delivers 90 minutes of integrity and 68 minutes of insulation, making it ideal for these high-stakes environments. In warehouses and logistics hubs, such as those near the Port of Merak, fire rated windows and doors are essential for maintaining egress routes and protecting stored goods. The 21mm FPOS glass, offering 120 minutes of integrity and 30 minutes of insulation, is a common choice for these applications. For factory floor partitions separating production lines, the 28mm EI60 panel provides a robust barrier that can withstand the thermal and mechanical stresses of an industrial setting. Antifires also supplies glass blocks for areas requiring both fire resistance and natural light transmission. These products are installed using certified steel frames and ceramic fiber seals, ensuring a complete system that meets the SNI 03-1735-2000 requirements. By integrating these solutions, Cilegon’s facility managers can create safe, compliant environments that protect personnel and assets across diverse operational zones.
