Fireproof windows with thermal insulation from the factory: prices to order 

Fireproof windows with thermal insulation: direct order from the manufacturer in 2026

Fireproof windows with thermal insulation- these are complex engineering structures designed to prevent the spread of fire, smoke and critical thermal radiation through light openings in buildings. Unlike standard glazing, such systems are able to maintain integrity (E) and provide thermal insulation capacity (I) for a regulated time - from 15 to 180 minutes. The request for “fireproof thermally insulated windows” reflects the need of industrial buyers and designers for solutions that are not only certified, but also energy efficient, which is critical for modern industrial complexes, Class A warehouses and public buildings.

By ordering these structures directly from the factory, you eliminate intermediary markups, receive a full package of permits (certificates of compliance with the EAEU TR, fire test reports) and the ability to adapt technical parameters to a specific object. In 2026, the market requires not only compliance with Federal Law-123 “On Fire Safety”, but also the integration of smart systems for monitoring the condition of double-glazed windows. We offer an integrated approach: from calculating thermal characteristics to installation and service, ensuring that the price matches the quality of workmanship.

What are fireproof thermally insulated windows and how do they work?

Many customers mistakenly believe that any reinforced or tempered glass is fire resistant. This is a fundamental misconception. When heated above 250°C, ordinary glass cracks and falls out of the frame, creating a draft for fire.Fireproof windows with thermal insulationare a multi-chamber system where not only the profile, but also specialized filling plays a key role.

Operating principle of multi-layer protection

The basis of the design is a multi-layer glass unit containing transparent fire-retardant layers (gels or special films). When exposed to an open flame, these layers foam, forming an opaque, insulating coke. This process is endothermic - it absorbs a huge amount of thermal energy, protecting the cold side of the window from heating.

• Integrity (E):The ability of a structure to prevent the penetration of flame and combustion products.
• Thermal insulation (I):The ability to limit temperature rise on an unheated surface. For rooms with large numbers of people, this parameter is critical, since thermal radiation above 14 kW/m² causes skin burns in seconds.
• Smoke tightness (S):An additional parameter that prevents toxic smoke from leaking through micro-gaps.

The engineering feature of our solutions is the use of thermal breaks in aluminum or steel profiles. Without a high-quality thermal break, the metal frame becomes a “cold bridge” and at the same time a heat conductor, which can lead to deformation of the structure and loss of tightness within 10-15 minutes of the fire, even if the glass has withstood the load.

Where fireproof windows with thermal insulation are used: industry specifics

The choice of fire resistance class directly depends on the functional purpose of the building and the fire hazard category of production processes. Incorrect selection leads to fines from the Ministry of Emergency Situations or, worse, to a tragedy during evacuation.

1. Industrial enterprises and workshops (Categories A, B, C)

Areas with flammable gases, liquids or dust require windows with a fire rating of EI 60 or higher. Not only fire protection is important here, but also shock resistance. Often these windows are combined with fire doors to create safe escape routes for personnel. Thermal insulation here prevents the ignition of materials in adjacent areas by reducing radiation heat transfer.

2. Warehouse complexes and logistics hubs

Modern warehouses store goods with different flammability. Windows in office extensions to warehouses (so-called “glass walls”) must have a class of EI 30 or EI 45. A special feature of the application is large areas of glazing for natural light, which requires a reinforced frame. Usagefireproof windows with thermal insulationallows you to reduce air conditioning costs in summer while maintaining safety.

3. Public buildings: shopping centers, hospitals, schools

Here the priority is maximum thermal insulation (class I) to protect people from heat shock. According to regulations, the temperature on the glass surface on the evacuation side should not exceed critical values. We recommend using structures with a limit of EI 30–EI 60 with the mandatory use of triplex on the inside to prevent fragmentation injuries in the event of destruction.

4. Energy and servers

Premises with a high risk of electrical fire require windows that are resistant to prolonged exposure to high temperatures without losing the dielectric properties of the frames. Powder-coated steel profiles that can withstand heat up to 800°C are often used.

Specifications and selection options

When forming technical specifications (TOR) for procurement, it is necessary to rely on specific digital indicators, and not on general descriptions. Below are the key parameters that affect the performance and price of the product.

Important engineering note:Not all suppliers honestly indicate the R₀ coefficient. Often the calculated value is taken for a conventional double-glazed window of the same thickness. Request a product passport, which indicates the thermal characteristics specifically for a specific configuration with fire-retardant filling. The density of the fire retardant gel is different from air, which affects convective currents inside the bag.

How to choose a supplier: reliability criteria in 2026

The market is oversaturated with offers, but only a small part of companies have their own full-cycle production. Orderingfireproof windows with thermal insulation, you are buying not just a product, but a guarantee of safety. A mistake in choosing a supplier can cost the supervisory authorities refusal to accept the object.

Manufacturer inspection checklist

1. Availability of valid certificates:Check the certificate number in the RosAccreditation register. The certificate must be issued specifically for the system (profile + glass + fittings) that is offered to you. Substitution of a component will void the certification.
2. In-house production of fire-resistant glass:Companies that purchase ready-made double-glazed windows from third parties cannot control the quality of gluing and primary sealing. This is a “weak link” through which depressurization and clouding of the gel often occur after 2-3 years.
3. Experience in implementing similar projects:Request a reference list for the last 2 years. The presence of facilities in your region indicates well-established logistics and service support.
4. Technical support at the design stage:A professional supplier must provide drawings of the connections between windows and building structures. Incorrect installation (for example, using regular polyurethane foam instead of fire-resistant foam) will negate all the properties of the window.

We, as a manufacturing plant, provide customers with access to a personal account, where they can track the status of the order, download an as-built diagram and receive advice from a process engineer in real time.

Price range and cost formation factors

The question “how much does it cost” does not have a clear answer without a project. However, understanding the pricing structure will help you optimize your budget. Price forfireproof windows with thermal insulationis formed from several components.

Cost structure

• Double-glazed window (up to 60% of cost):The higher the fire resistance class, the more layers of fire retardant film or thicker the gel layer is required. EI 15 glass costs 3-4 times more than regular tempered glass. Glass EI 60 - 8-10 times.
• Profile system (20-25%):Steel profiles are cheaper than aluminum profiles with thermal break, but require anti-corrosion treatment. Aluminum systems are more difficult to produce, but more aesthetically pleasing and lighter.
• Fittings and components (10%):Fire-resistant handles and hinges that can withstand temperature deformation are much more expensive than standard ones.
• Logistics and installation (10-15%):Transportation of heavy double-glazed windows requires special equipment. Installation must be performed by certified crews using fire-resistant sealants and foams.

Estimated prices (for 2026, excluding installation):

• Window EI 15 (aluminum): from RUB 25,000/m²
• Window EI 30 (aluminum with thermal break): from RUB 45,000/m²
• Window EI 60 (steel/aluminum reinforced): from RUB 75,000/m²
• Window EI 90-120 (special projects): from RUB 110,000/m²

Prices may vary depending on exchange rates (as some components of fire retardant compounds are imported) and the complexity of the product geometry. Arched, triangular or round windows require individual adjustment of equipment, which increases the cost by 20-30%.

Technology Comparison: Gel Fillers vs Multilayer Films

When choosing filling for a double-glazed window, a dilemma often arises between two main technologies. Understanding their differences will help you avoid operational problems.

Expert recommendation:For objects with high aesthetic requirements (offices, hotel lobbies, museums), we definitely recommend premium gel fillers. For industrial areas, warehouses and technical premises where visual transparency is not a priority, film technologies can significantly save the budget without losing the level of safety.

Logistics, installation and export capabilities

Delivery of large and fragile structures requires a special approach. We use specialized pyramids to transport glass, eliminating vibration loads. Each product unit is marked with a QR code containing information about the fire resistance class, production date and composition.

Installation features

Typical errors when ordering and using

An analysis of service calls for 2024-2025 revealed a number of recurring problems related not to product quality, but to errors in the design and use stages.

1. Ignoring wind loads.
At high altitudes or in open industrial areas, wind loads may exceed standard values. If you do not install a reinforced profile, the window may vibrate, which will lead to depressurization of the glass unit and failure of the gel long before the fire.

2. Improper surface care.
Fire-resistant glass is sensitive to abrasive cleaning agents and alkaline solutions. Their use destroys the outer protective coating, making the glass cloudy. It is recommended to use only soft fabric materials and neutral detergents.

3. Independent replacement of fittings.
Installing conventional hinges instead of fire hinges (which have a higher melting point of lubricant elements and structure) is strictly prohibited. In the event of a fire, such a hinge will melt first, and the sash will fall, opening access to the fire.

FAQ: Frequently asked questions

Is it possible to install fireproof windows with thermal insulation in a private home?

Yes, this is possible and advisable if the house is located in dense buildings or near a forest. Although strict EI standards are not always mandatory for private housing, such windows provide additional protection for property and reduce heat loss. However, it is worth considering the high cost and weight of the structures.

How long do these windows last?

Service life of qualityfireproof windows with thermal insulationis 15-25 years, subject to compliance with operating rules and regular maintenance (checking tightness, operation of fittings). The manufacturer provides a guarantee that the fire retardant properties will be maintained throughout the entire service life.

What to do if the glass becomes cloudy?

Cloudiness or the appearance of bubbles indicates depressurization of the glass unit. Such a window loses its heat-insulating and, partially, fire-retardant properties. It needs to be replaced. Whether this is a warranty case or not is determined by an expert examination: if the seal failure occurred due to a factory defect, the replacement is free, if due to mechanical damage or improper installation, it is at the expense of the owner.

Does profile thickness affect the price?

Yes, directly. The wider profile allows for the installation of thicker glass units required for high fire resistance classes (EI 60 and above). In addition, wide profiles require more metal and complex thermal break processing, which increases the cost of the product.
