Kazakhstan’s SNiP 2.01.02-85 Fire Resistance Mandates for Almaty Commercial High-Rises
Almaty’s skyline is defined by high-rise commercial towers that must comply with SNiP 2.01.02-85, which mandates fire resistance ratings for load-bearing and non-load-bearing partitions. This standard requires that fire compartments in buildings exceeding 28 meters maintain integrity for at least 60 minutes, with critical escape routes often demanding up to 120 minutes. Antifires addresses these requirements with glazed systems that combine structural robustness with verified fire performance.
Our solutions utilize G.M.S. hollow steel frames paired with fire-rated insulation boards (12–15mm) and ceramic wool seals (3–6mm, density 210 kg/m³) to prevent flame and smoke propagation. For example, the 21mm FPOS multi-layer composite glass delivers 120 minutes of integrity and 30 minutes of insulation, making it suitable for open-plan office partitions in Almaty’s business districts. Key installation parameters include:
- Expansion gaps: 3–5mm filled with ceramic fiber to accommodate thermal movement.
- Fixing anchors: M6/M8 bolts spaced at 300–600mm intervals for seismic resilience.
- Pressure management: Furnace test conditions (0 ±2Pa) ensure real-world performance under stack effect pressures common in high-rises.
These technical specifications directly support compliance with local fire compartmentation strategies, particularly in Almaty’s dense urban zones where fire spread risks are elevated.
Selecting E and EI Class Fire Rated Glass for Almaty’s Extreme Seasonal Temperature Variations
Almaty’s continental climate, with winter lows of -30°C and summer highs of +35°C, imposes unique demands on fire rated glazing. Thermal cycling can compromise seal integrity and glass stability, making material selection critical. Antifires offers both E-class (integrity only) and EI-class (integrity and insulation) systems, each engineered to maintain performance under extreme temperature variations.
The E90 glass (6mm, 90-minute integrity per BS 476 Part 22) is ideal for curtain walls where thermal insulation is secondary, while the 50mm EI120 ultra-high-performance glass provides 120 minutes of both integrity and insulation, with a thermal transmittance (U-value) as low as 1.2 W/m²K. This is particularly relevant for atrium applications in Almaty’s mixed-use developments, where large glazed surfaces must balance fire safety with energy efficiency. Key structural features include:
| Glass Type | Integrity (min) | Insulation (min) | U-Value (W/m²K) |
| 10mm FPOS | 135 | 16 | 2.8 |
| 15mm FPOS | 132 | 34 | 2.1 |
| 28mm EI60 | 66 | 64 | 1.8 |
| 54mm EI120 | 120 | 120 | 1.2 |
These systems incorporate intumescent gel layers that activate at high temperatures, forming an insulating barrier that prevents radiant heat transfer—a critical factor in maintaining safe egress paths during Almaty’s harsh winters.
Fireproofing Almaty’s Key Infrastructure: Shopping Centers, Hospitals, and Underground Parking Garages
Almaty’s key infrastructure projects—such as the Dostyk Plaza shopping district and the city’s expanding hospital network—require compartmentation solutions that prevent smoke spread in high-traffic zones. Our fire door systems and fire windows are specifically deployed in underground parking garages to protect ventilation shafts and in hospital corridors to create safe egress paths, directly addressing the fire load risks associated with mixed-use building designs.
For shopping centers, where fire loads from retail goods and crowds are high, the 26mm door glass (89 minutes integrity, 68 minutes insulation) provides a robust barrier. In hospital settings, where patient mobility is limited, the 28mm EI60 panel ensures that corridor partitions maintain both integrity and insulation for over 60 minutes, allowing safe evacuation. Installation protocols include:
- Ceramic tape seals: 3mm thickness, density 210 kg/m³, to prevent smoke leakage at joints.
- Intumescent fire seals: 20mm × 4mm strips that expand under heat to seal gaps.
- Thermocouple monitoring: Type K sensors (9–12 channels) during testing ensure unexposed side temperature rises stay below 140°C average.
These measures are vital for Almaty’s mixed-use zones, where fire compartmentation must account for both vertical and horizontal smoke spread.
Why Almaty Architects Trust Antifires for Certified Fireproofing and On-Site Technical Support
Antifires combines a decade of international B2B expertise with localized knowledge of Kazakhstan’s certification process. Architects in Almaty trust our systems because we provide full EN 13501-1 test reports and assist with local SNiP documentation, ensuring seamless approval from construction committees. Our direct factory-to-project supply chain reduces lead times, a critical advantage for the city’s fast-paced development schedules.
Key differentiators include:
- Certified performance: All products tested under BS EN 1634-1 and AS1530.4, with data such as the 8mm glass system achieving 73 minutes integrity.
- On-site support: Technical teams provide installation guidance for expansion gaps (3–5mm) and anchor bolt spacing (300–600mm), tailored to Almaty’s seismic conditions.
- Localized documentation: We translate test reports into Russian and Kazakh, facilitating approval by the Kazakhstan Committee for Construction and Housing.
For complex projects like Almaty’s new financial district towers, our 120-minute fire rated glass solutions provide the highest level of protection, backed by verified test data and local compliance expertise.
