Understanding Jerusalem Fire Safety Standards Under Israeli Standard SI 921 and Local Bylaws
Jerusalem’s fire safety landscape is defined by the convergence of Israeli Standard SI 921 and municipal building codes that address both contemporary construction and historic preservation. SI 921 mandates rigorous testing for fire resistance, classifying glazed assemblies based on integrity (E) and insulation (I) performance, with ratings ranging from 30 to 120 minutes. Local bylaws in Jerusalem often impose additional criteria for projects near heritage sites, such as the Old City, where fire-rated glazing must be installed without altering the visual character of existing structures. Antifires products are engineered to comply with these dual requirements, utilizing advanced multi-layer glass compositions that incorporate intumescent gels to achieve certified fire performance. For example, systems rated for EI60 or EI120 are tested under conditions that simulate Jerusalem’s thermal extremes, with furnace pressures maintained at 0 ±2 Pa and ambient temperatures recorded during testing between 27°C and 36°C. The integration of steel or aluminum frames with ceramic wool seals and intumescent fire seals ensures that thermal expansion is managed effectively, preventing structural failure during a fire event. This technical precision allows contractors to specify glazed partitions and doors that meet both SI 921 certification and the aesthetic demands of Jerusalem’s diverse building typologies, from modern commercial towers to restored historic structures.
Selecting Fire Rated Glass Grades for Jerusalem’s Climate and Structural Demands
Selecting the appropriate fire-rated glass for Jerusalem’s projects requires careful consideration of the city’s climate, which features hot, dry summers and cool, wet winters, as well as its seismic activity. Antifires offers a range of EI and EW rated glass systems, with fire resistance durations from 30 to 120 minutes, designed to perform reliably under these conditions. The glass compositions, such as the 21mm multi-layer composite structure achieving 120 minutes integrity and 30 minutes insulation, are engineered to withstand thermal shock and maintain structural stability. For high-rise residential towers, 60 minute fire rated glass with both integrity and insulation properties is commonly specified for stairwell enclosures and corridor partitions, ensuring safe egress routes. In commercial complexes, EW120-rated glass provides radiation control while allowing natural light transmission, critical for open-plan office layouts. The integration with steel frames, using M6 or M8 anchor bolts at 300–600mm spacing, accommodates thermal expansion and seismic loads, as verified by deflection measurements of up to 152mm during testing. This technical approach ensures that Jerusalem’s buildings meet both fire safety codes and the structural demands of the region, providing reliable protection across all seasons.
Fire Rated Glass Applications in Jerusalem’s Key Construction Sectors and Projects
Fire-rated glazing from Antifires is deployed across Jerusalem’s key construction sectors, including high-rise residential developments, government infrastructure, and educational institutions. In new city-center towers, EI60 and EI90 rated glass systems are installed in stairwell enclosures and lift lobbies to maintain compartmentation and protect evacuation routes. These systems, tested to BS EN 1364-1, utilize multi-layer tempered glass with intumescent gels that expand under heat, forming a barrier against flames and smoke. For renovated historic structures near the Old City, fire-rated partitions and doors are designed to meet preservation constraints while providing up to 120 minutes of integrity. The use of ceramic wool seals and intumescent fire strips ensures that expansion gaps of 3–5mm are effectively sealed during a fire event. In government buildings and schools, fire partition solutions are specified for corridor and room separations, offering both safety and transparency. These applications demonstrate how Antifires products address the dual challenges of modern safety codes and historic preservation, delivering certified performance that aligns with Jerusalem’s unique urban fabric.
