Aligning Fire Rated Glass with DBN B.1.1-7 Fire Resistance Requirements in Mariupol
Mariupol’s building codes under DBN B.1.1-7 require that glazing in escape routes and fire compartments achieve specific fire resistance ratings, typically EI 30 (30 minutes) for low-risk areas and EI 60 (60 minutes) for high-occupancy zones such as stairwells and hospital corridors. These ratings demand that the glass assembly prevents flame passage (Integrity) and limits temperature rise on the unexposed side to an average of ≤140°C and a maximum of ≤180°C (Insulation).
Antifires addresses these requirements with tested configurations that combine multi-layer glass and intumescent gel layers. For instance, the 28mm EI60 panel (6mm + 5.5mm gel + 5mm + 5.5mm gel + 6mm) has demonstrated Integrity of 66 minutes and Insulation of 64 minutes under BS EN 1364-1 conditions. This performance is critical for Mariupol’s high-rise residential towers, where fire compartmentation must remain intact to allow safe egress. The assemblies are installed in G.M.S. hollow steel frames with ceramic wool seals (3–6mm, density 210 kg/m³) and intumescent fire seals (20mm × 4mm) to prevent gap penetration. By selecting 90-minute fire rated glass for critical stairwells, designers can exceed minimum code requirements, providing an added safety margin during evacuation.
Technical Parameters for Fire Rated Glass Grades in Mariupol’s High-Humidity Environments
Mariupol’s proximity to the Sea of Azov introduces high humidity and saline air, which can accelerate corrosion of metal frames and degrade sealant performance. For fire rated glass systems to maintain their certified performance over time, material selection must account for these environmental factors. Antifires uses G.M.S. hollow steel sections with corrosion-resistant coatings and ceramic fiber expansion gaps (3–5mm) that remain stable under moisture exposure. The intumescent gel layers within the glass (e.g., 4mm or 5.5mm layers in 10mm FPOS or 26mm door glass) are sealed between float glass panes, preventing moisture ingress that could compromise insulation properties.
Test data from controlled environments (ambient temperatures of 27–36°C and relative humidity of 43–90%) confirm that these assemblies maintain their Integrity and Insulation ratings under varied conditions. For Mariupol’s reconstruction projects—such as port-side commercial buildings or industrial warehouses—Antifires recommends 120-minute fire rated glass for high-risk zones, which uses a multi-layer insulated structure (50mm or 54mm thickness) to provide both fire resistance and thermal efficiency. The combination of tempered glass and intumescent gel ensures that even in humid coastal climates, the glazing will not delaminate or lose its fire-stopping capability over the building’s lifespan.
Engineering Project Demands for Fire Rated Glass in Mariupol’s Industrial and Residential Reconstruction
Mariupol’s reconstruction encompasses diverse project types, from industrial manufacturing plants to multi-story residential blocks and public hospitals. Each application imposes distinct demands on fire rated glass systems. In industrial settings, where large glazed partitions separate production areas from storage zones, the glass must withstand high thermal gradients and potential impact. Antifires supplies 21mm FPOS assemblies (Integrity 120 min, Insulation 30 min) that are suitable for such environments, as they provide extended integrity to prevent fire spread while allowing for visual monitoring of operations.
For residential high-rises, the focus shifts to door glass and window systems that combine fire safety with everyday usability. The 26mm glazed door glass (5mm + 5.5mm gel + 5mm + 5.5mm gel + 5mm) achieves Integrity of 89–90 minutes and Insulation of 68 minutes, making it ideal for apartment entry doors that must resist fire for at least 60 minutes per local codes. In public buildings like schools or hospitals, EI60-rated partitions (e.g., 28mm panels) are installed in corridors to create smoke-tight compartments. All systems are fixed using M6/M8 anchor bolts at 300–600mm spacing, ensuring structural stability even under the negative pressure conditions (0 ±2 Pa) typical of fire tests. By matching the glass rating to the building’s occupancy and risk profile, engineers in Mariupol can optimize both safety and cost.
Antifires Brand Advantages for Mariupol: Local Compliance and Post-War Supply Reliability
Antifires distinguishes itself in the Mariupol market through a combination of certified compliance and logistical reliability. All products are tested under BS 476 Part 22, BS EN 1634-1, and ASTM E119, providing documentation that directly supports DBN B.1.1-7 equivalency. The company’s test database includes over 135-minute furnace runs with detailed thermocouple monitoring (10–55 channels on the unexposed surface), ensuring that every rating—from E90 to EI120—is backed by empirical data. For Mariupol’s reconstruction projects, which often face tight deadlines and supply chain disruptions, Antifires maintains stock of standard sizes (e.g., 10mm, 15mm, 21mm, and 28mm glass) and frame components, enabling rapid delivery.
Furthermore, the brand’s technical support team provides installation guidance specific to local conditions, including proper use of ceramic wool and intumescent seals to account for expansion gaps (3–5mm). This reduces the risk of field failures that could compromise fire ratings. By choosing Antifires, contractors in Mariupol gain access to a global supply chain with local compliance expertise, ensuring that fire rated glass systems not only meet regulatory requirements but also perform reliably in the city’s unique post-war environment.
