Fireproof windows with a smoke removal system: buy from the factory 

Fireproof windows with a smoke exhaust system: technical requirements and direct supplies from the manufacturer

Fireproof windows with smoke removal systemare specialized translucent structures integrated into automated smoke protection systems for buildings. Their key function is not only to ensure fire resistance (limits EI 30, EI 45, EI 60), but also to promptly remove toxic combustion products in the early stages of a fire. Unlike standard transoms, such systems are activated by a signal from fire automatics, creating the necessary draft to reduce the temperature in the room and ensure the safe evacuation of people. For industrial facilities, warehouse complexes and public buildings, the presence of certified windows with a smoke removal function is a mandatory requirement in accordance with SP 7.13130.2013 and the Technical Regulations on Fire Safety Requirements (FZ-123).

Orderingfireproof windows with smoke exhaust systemDirectly from the plant, designers and purchasers receive a guarantee that products comply with the declared fire resistance characteristics and aerodynamic parameters. We produce structures from aluminum and steel profiles using thermal breaks and special fire-resistant glass that can withstand thermal shocks up to 1000°C. The integration of electric drives with backup power ensures that the doors open even when the main power supply is turned off. This solution is critical to minimizing damage from smoke, which often exceeds the damage from the fire itself.

Operating principle and design features of smoke removal systems

The efficiency of the system depends on the synchronization of several engineering units.Fireproof windows with smoke removal systemoperate in two main modes: daily (ventilation) and emergency (smoke removal). Switching between modes occurs automatically through a controller associated with the fire alarm system (AFS).

Key Design Components

• Profile system:Reinforced aluminum or steel profiles with a fire resistance class of at least EI 30 are used. Aluminum systems use special thermal inserts made of reinforced fiberglass or foamed polymers, which prevent heat transfer from the outside of the window to the inside.
• Translucent filling:Multi-chamber fire-resistant glass or glass blocks filled with transparent gel are used. When heated, the gel foams, forming an insulating coke that protects the integrity of the glass and prevents the spread of flame.
• Drive group:Chain or rod electric drives with a force from 400 N to 1000 N. It is mandatory to have an uninterruptible power supply unit (UPS) that ensures operation of the drives for at least 30 minutes after a power outage.
• Seals:Thermal expansion tapes around the perimeter of the vestibule. At temperatures above 150-200°C, they increase in volume, sealing cracks and blocking the access of oxygen, which is necessary to maintain the fire resistance limit.

It is important to understand that the mechanics of opening such windows differ from their household counterparts. The opening angle is often limited to 90 or 180 degrees to maximize the clear area through which smoke is removed. The opening speed is regulated by regulations: full activation must occur within 10–60 seconds after receiving an alarm signal, depending on the volume of the room.

Where are fireproof windows with a smoke exhaust system used?

The scope of application of these structures is strictly regulated by regulatory documents of the Russian Federation and the EAEU countries. Installation is justified where natural ventilation cannot cope with the removal of flue gases, and the use of mechanical smoke extractors is economically or technically difficult.

Industrial facilities and warehouses

In workshops with a ceiling height of more than 6 meters, smoke accumulates under the ceiling, creating a “smoke cushion”.Fireproof windows with smoke removal systeminstalled in the upper zone of the facade or in skylights, allow this superheated air to be discharged. This reduces the risk of collapse of supporting structures due to temperature deformations of the metal. For warehouses of categories B1-B3 in terms of explosion and fire hazard, such windows are part of the passive protection that allows you to preserve goods and equipment.

Public buildings and shopping centers

In shopping malls, atriums and train stations, the main threat to people's lives is toxic smoke, not fire. Windows with smoke exhaust provide a supply of clean air in evacuation zones. According to calculations, effective smoke removal through natural openings can reduce the concentration of carbon monoxide (CO) to safe values ​​(<0.1%) during the first 5-7 minutes of a fire, which is critical for evacuation time.

High-rise residential complexes

In modern business and premium class residential complexes, such systems are installed in stairwells and elevator halls. They prevent smoke from filling escape routes by isolating the source of the fire. The aesthetic component is especially important here: the profile should be narrow, and the glazing should be as transparent as possible, so as not to disturb the architectural appearance of the facade.

Specifications and selection options

When forming a technical specification for a purchase, it is necessary to take into account a number of physical and mechanical parameters. An error in aerodynamic efficiency calculations may result in the system being unable to cope with the volume of smoke.

Engineering practice shows that most system failures are not related to the quality of the glass, but to the incorrect selection of drives. If the drive power reserve is less than 20% of the required opening force (taking into account the snow load on the sash in winter), the mechanism may jam at a critical moment. Therefore, we recommend that you always include a safety factor of 1.2-1.3 when calculating torque.

How to choose a supplier: plant reliability criteria

The market offers many solutions, butbuy fireproof windows with a smoke removal systemWith a guarantee of passing inspections of the Ministry of Emergency Situations, it is possible only from manufacturers who have a full chain of quality control. When choosing a contractor, pay attention to the following aspects:

1. Availability of valid certificates of conformity with TR EAEU 043/2017.Check the certificate number in the RosAccreditation register. Often companies show certificates for the profile, but not for the finished product complete with fittings and glass. This is a serious mistake: fire resistance is certified only for a specific configuration.
2. Own design bureau and production base.The factory should be able to adapt the junction units to your façade systems. Standard solutions are rarely suitable for complex architectural forms. The ideal option is a company that combines competencies in building structures and heavy engineering, which guarantees the highest manufacturing precision and reliability of welded joints.
3. Experience in integration with automation systems.The supplier must provide communication protocols for connecting windows to dispatch bundles (Modbus, Dry Contact). Lack of technical support at the stage of setting up automation is a common reason for the failure of the commissioning of a project.
4. Logistics and installation.Fireproof windows require special handling during transportation (risk of glass edge chipping). The presence of the plant’s own installation teams trained to work with fire joints and sealants removes the risk of claims from technical supervision from the customer.

Chongqing Huaxia Windows and Doors Co., Ltd.: an industrial approach to security

The choice of a reliable partner determines the success of the entire project. Chongqing Huaxia Windows and Doors LLC, a Russian legal entity operating under a strategic alliance with Chongqing Huaxia Steel Structures LLC, is an example of such an integrated approach. Based in the key industrial hub of Chongqing, the company pursues a unique dual business model that combines energy efficiency in construction and intelligent manufacturing in heavy industry.

This synergy allows us to offer the market not just windows, but high-tech enclosing structures that have been tested under extreme conditions. Our experience in harsh climates and aggressive industrial environments is transferred directly to the production of fireproof systems. We use advanced thermal break and multi-circuit sealing technologies, providing not only high fire resistance, but also excellent wind protection and airtightness.

The company's production base combines the capabilities of two specialized enterprises: one in the field of construction metal structures, the other in the field of heavy engineering. This provides a full cycle of metal processing: from design and cutting to welding, painting and final assembly. Strict quality control at all stages (input, operational and output) ensures that every window leaving our factory meets the most stringent reliability requirements. This production integration allows us to quickly adapt to urgent orders and import substitution projects, maintaining stable delivery times even with high volumes.

Comparison of materials: Aluminum vs Steel

The choice of frame material determines not only the cost, but also the durability of the system. Below is a comparison of the two main technologies used in 2026.

Engineer Recommendation:For office centers and facades with high insolation requirements, definitely choose aluminum. For harsh industrial environments, chemical plants, or renovating old factory floors, steel may be a more practical and maintainable option. However, keep in mind that steel windows are more difficult to automate due to the heavy weight of the sashes.

Chongqing Huaxia LLC's product range includes both energy-efficient colored steel window and door systems (60, 75, 120 series) and 50 series insulated steel painted windows. These solutions are designed to withstand harsh environments, making them an ideal choice for facilities where standard aluminum systems may not be able to handle the load.

Price range and cost formation factors

Costfireproof windows with smoke exhaust systemvaries widely. In 2026, the average market price per square meter of a finished turnkey product (including automation) is:

• Basic equipment (EI 30, aluminum): from RUB 45,000/m².
• Reinforced equipment (EI 45-60, complex shapes): from 65,000 to 90,000 rubles/m².
• Premium segment (panoramic glazing, hidden drives): from RUB 100,000/m².

What affects the final budget?

The price depends not only on materials. A significant part of the estimate is occupied by:

• Certification tests:Each new size group requires expensive testing in an accredited laboratory. Factories producing large batches distribute these costs, reducing the price for the client.
• Glass type:Single-chamber fireproof glass is cheaper than multi-chamber glass. The use of glass filled with argon gas increases the price, but improves thermal insulation.
• Intelligent automation:Simple open/close actuators are cheaper than systems with wind, rain and temperature sensors integrated into a BMS (Building Management System).
• Installation complexity:Working at heights and the need for climbers or lifts increases the cost of installation work by 30-50%.

Purchasing directly from the factory allows you to eliminate the dealer markup (usually 20-30%) and get flexible payment terms, for example, breaking the payment into stages: prepayment for materials, payment before shipment and postpayment after installation.

Typical mistakes when designing and ordering

An analysis of complaints over the past 3 years has revealed recurring problems that lead to delays in the delivery of objects or failures during inspections by supervisory authorities.

1. Ignoring wind loads

Designers often install standard windows, not taking into account that the sash is open in smoke extraction mode. In strong winds, the open flap acts like a sail. If the drive is not designed to hold the sash during wind gusts of 20-25 m/s, it may slam shut or, conversely, be torn out. Solution: install wind sensors that block opening during a storm, or use drives with mechanical locking.

2. Incompatibility of profiles and seals

The use of cheap analogues of sealing tapes that have not passed tests for compatibility with a specific profile. In case of fire, the tape must foam in a strictly defined manner. If it falls out or foams unevenly, smoke penetrates into adjacent rooms. We use only certified components supplied with the main profile.

3. Electrical errors

Incorrect calculation of cable cross-section for low-voltage drives (24V). With a line length of more than 50 meters, a voltage drop can cause the actuators to open out of sync or not develop full force. Requires the use of cables with a larger cross-section or installation of local power supplies near the window.

FAQ: Frequently asked questions

Q: Is it possible to install a smoke extraction system on existing regular windows?
Oh no. Conventional windows do not have the required fire resistance rating (EI). In the event of a fire, the glass will burst due to thermal shock, and the structure will lose its tightness. A complete replacement of the translucent structure with a certified fireproof one is required.

Q: How often do these windows need to be serviced?
A: According to the regulations, the operability of drives and control systems must be checked at least once a quarter. Full maintenance including checking seals and lubrication of mechanisms - once a year. We offer service contracts with an on-site engineer.

Q: What happens to the window if the power goes out?
A: The system is equipped with batteries (UPS), which provide a minimum of 3-5 full opening/closing cycles or holding open for 30-60 minutes. This is enough for evacuation and fire brigades.

Q: Does the color of the profile affect fire resistance?
A: Powder painting in standard colors (RAL) does not affect the fire resistance limit if the layer thickness does not exceed 80-100 microns. However, dark colors can heat up more strongly in the sun, which is taken into account when setting up automatic temperature sensors.

Conclusion and purchasing recommendations

Investments in qualityfireproof windows with smoke exhaust systemis not just compliance with legal requirements, but also a real tool for reducing insurance risks and protecting human lives. The 2026 market shows a trend toward the integration of these systems into unified digital smart building ecosystems, where security is controlled by artificial intelligence algorithms that analyze data from thousands of sensors.

When choosing a supplier, give preference to factories with a full production cycle: from profile cutting to automation assembly. This ensures that all nodes are consistent and have a single point of responsibility. Avoid assemblers who buy components from different vendors - in the event of an accident, it is extremely difficult to find the culprit in such a chain.
