DBN V.1.1-7 and National Fire Safety Compliance for Kryvyi Rih Building Projects
Kryvyi Rih’s construction sector must navigate the technical requirements of DBN V.1.1-7:2016, which explicitly defines fire resistance classes for glazed partitions, doors, and windows. For high-rise residential towers and administrative centers, the code typically demands EI 30 to EI 60 ratings for internal compartment walls, while escape route enclosures may require EI 60 to EI 120. Antifires products are designed to meet these thresholds using certified multi-layer glass compositions. For instance, the 28mm EI60 panel (tested to BS EN 1634-1) provides Integrity of 66 minutes and Insulation of 64 minutes, making it suitable for Kryvyi Rih’s residential stairwells. The following table summarizes key product grades relevant to local compliance:
| Product Thickness | Fire Rating (DBN Equivalent) | Typical Application |
| 10mm FPOS | E 135 / I 16 | Vision panels in non-insulated partitions |
| 26mm Door Glass | EI 60 | Fire doors in residential corridors |
| 50mm / 54mm | EI 120 | Industrial control room enclosures |
All installations must use G.M.S. hollow steel frames with ceramic wool (3–6mm, density 210 kg/m³) and intumescent fire seals (20mm × 4mm) to ensure system integrity under furnace test conditions. This approach guarantees that Kryvyi Rih projects pass local inspections without deviation.
Selecting Fire Rated Glass Grades for Kryvyi Rih’s Extreme Thermal and Impact Conditions
Kryvyi Rih’s extreme thermal and impact conditions—stemming from its steel plants and mining infrastructure—require fire rated glass that can withstand both radiant heat and mechanical stress. Local regulations reference EN 13501-2 for classification, and Antifires integrates both Ukrainian DBN and European standards to deliver robust performance. For industrial control rooms near blast furnaces, the 50mm ultra-high-performance glass (tested to ASTM E119 and BS 476 Part 22) offers Integrity and Insulation up to 120 minutes, effectively containing heat flux that could exceed 180°C on the unexposed side. The glass composition uses multi-layer tempered glass with intumescent gel, which activates at high temperatures to form a protective char layer. This is critical for Kryvyi Rih’s mixed-use developments where evacuation routes must remain clear for extended periods. The selection process prioritizes EW120 ratings for radiation control in areas adjacent to high-temperature processes, ensuring that personnel can safely pass within 1 meter of the glazing. Contractors should specify ceramic tape (3–6mm) for expansion gaps (3–5mm) to accommodate structural movement without compromising fire resistance. These features make Antifires systems ideal for Kryvyi Rih’s demanding industrial environment.
Building Application Scenarios for Fire Rated Systems in Kryvyi Rih’s Urban and Industrial Projects
Antifires fire rated systems are deployed across Kryvyi Rih’s urban and industrial projects, addressing specific compartmentation and life safety needs. In high-rise residential towers, fire rated glass doors with 26mm EI60 construction are installed in stairwells and lobbies to maintain escape route integrity. For metallurgical plants, 50mm EI120 glazed partitions separate control rooms from furnace areas, preventing thermal radiation from reaching operators. In commercial office buildings, 21mm FPOS (Integrity 120 min, Insulation 30 min) is used for atrium enclosures, balancing transparency with fire safety. The following list outlines key application scenarios:
- Industrial control rooms: 50mm EI120 glass with steel frames and ceramic wool seals to withstand blast furnace heat.
- Residential stairwells: 28mm EI60 panels with intumescent seals for smoke and flame containment.
- Hospital corridors: 15mm FPOS (Integrity up to 132 min) for vision panels in evacuation routes.
Each system is tested under conditions simulating Kryvyi Rih’s climate (ambient 27°C–36°C, humidity 43%–90%), ensuring reliable performance year-round. Fire partition solutions are customized to meet specific building codes, with anchor bolts spaced at 300–600mm for secure fixing.
Why Kryvyi Rih Contractors Choose Antifires for Certified Fire Rated Glass and Doors
Kryvyi Rih contractors choose Antifires for verified compliance with DBN V.1.1-7:2016 and international standards like BS EN 1634-1. The products are backed by certified test data from accredited laboratories, ensuring that each glazing system meets the required Integrity and Insulation ratings for local projects. Key advantages include:
- Certified documentation: Ukrainian-language test reports and certificates for Derzharchbudinspektsiya approval.
- Technical support: On-site guidance for frame installation, sealant application, and expansion gap management.
- Diverse product range: From 6mm E90 integrity-only glass to 54mm EI120 insulated panels.
The use of G.M.S. steel frames and intumescent fire seals ensures system reliability under furnace test conditions, with maximum deflection of 38–152mm toward the furnace being within acceptable limits. Contractors also benefit from the availability of ceramic wool (density 210 kg/m³) and M6/M8 anchor bolts for secure installation. This combination of technical rigor and local compliance makes Antifires the preferred partner for Kryvyi Rih’s building professionals.
