About fire cuts at the ventilation facades

It is essential to comprehend fire safety protocols in both residential and commercial buildings, particularly in relation to ventilation facade design and construction. The maintenance of appropriate air circulation and indoor air quality is greatly aided by these facades. But they also bring unique difficulties when it comes to fire safety, especially when it comes to stopping the spread of fire through gaps like vents and ducts.

In order to prevent the spread of fire, ventilation facades must include fire cuts, also referred to as fire breaks or fire compartments. These cuts serve as barriers that are carefully positioned to keep fire contained in specific areas and stop it from spreading quickly throughout the structure. Fire cuts help to improve overall safety measures and reduce potential damage by compartmentalizing the facade.

Fire-resistant materials, such as intumescent strips, fire-rated seals, or specifically made barriers that can tolerate high temperatures, are typically used to build fire cuts. To make sure these materials can effectively withstand the heat and flames during a fire incident, they are chosen in accordance with strict safety standards. To guarantee that these fire cuts operate as intended in an emergency, proper installation and maintenance are essential.

We’ll discuss the critical function of fire cuts in ventilation facades in an article for "All about the facades of the house." These incisions are crucial safety elements intended to stop a fire from spreading throughout the building envelope. Homeowners and builders can make sure that their facades prioritize fire safety in addition to improving the house’s aesthetic appeal by properly installing them and understanding their purpose. This post will explore the benefits of fire cuts, their operation, and the best ways to incorporate them into facade design and construction.

Requirements for fire stained glass windows

Using specifically created test procedures, the resistance of fire-stained glasses is examined in accordance with GOSTs 30247.1-94 and 30247.2-97.

The proper factory markings, such as the product’s letter designation, fire resistance limit, GOST number, and manufacturer’s trademark, must be present on fire structures installed within the premises. Indelible and worn, with easy-to-read text on the front.

Fires must be accompanied by documentation detailing the company that produced the goods, a certificate attesting to the quality of the finished products, and a license for the specialists who installed the partitions and stained glass.

What is this facade structure

This is just a frame that is used to mount the finishing material. The frame is fastened to the house’s front facade. This technology is unique in that it creates an air space between the walls of the house and the décor. Because of the open air circulation in this area, the humidity and thermal return of the building are decreased. These are not the only two crucial factors in the circumstances surrounding the contemporary operation of private homes.

It’s important to note that the term "ventilation facades" is frequently used.

Note that this name does not accurately represent the essence of the technology being used, but rather is fundamentally true. One feature of the structure that does not have any equipment or devices that pump or remove air masses is the ventilated hinged facade. Inside the space, the air moves in accordance with only physical laws.

How to make a corrugated board fastening

A profiled sheet is fixed to the frame by installation.

A 35-cm-step galvanized self-tapping screw with a rubber gasket is fastened to a corrugation. Corrugated board self-cuts feature a thread and a unique drill-shaped tip. Typically, they are made from C1022 brand high-strength alloy carbon steel with a zinc finish. Self-tapping screws with this kind of tip design make it possible to attach them to the frame without first drilling holes.

Therefore, self-cuts for 4.8 mm diameter corrugated board can drill 2.5 mm thick metal.

Moisture is kept out of building material cavities by rubbing gaskets.

Sheets consistently fit with a 5 cm overlap. A burr is removed from the metal before cutting it to prevent cutting.

Other fixed elements are found around the entire perimeter of the house, including the corners, doors, and windows. After that, the structure has a finished, tidy appearance.

Fire cutters: Requirements of SNiP and PB

Metal components known as cuts are affixed to the building’s walls and encircle the building. Their objective is to halt the airflow. Both solid and perforated cuts are possible.

In the event of a fire, these facade components will prevent the fire from spreading throughout the building and prevent the molten plastic droplets from escaping the insulator. However, if the cuts are perforated, the facade’s ventilation will still function. However, because the perforation holes are too small, fire cannot spread to another location.

Buildings that use polystyrene or polyurethane foams as heaters in the facade system must have fire cutouts. Оогда эти утеплители подвергаются действия огня, они плавятся и выделяют разнообразные ядовитые газы, которые такье являются горючими. As these gases enter the fire, the intensity of combustion rises. In the event that the foam polysterol used for the facade is manufactured subpar, it may even catch fire right away, endangering the structure as a whole.

Fire cuts, which are constructed of refractory materials like metal or basalt, are added to the building to prevent such dangerous moments. The melting point of these materials is more than a thousand degrees. Since fiberglass melts at 550 degrees, it cannot be used for cuts.

Each structure’s specific needs for the quantity of firefighter elements on the facade as well as the materials used to create them must be determined.

However, the cuts come with general instructions. Mounting cuts at ceiling level should be spaced no more than four meters apart vertically. They go through the insulation and are fastened to the wall itself. The incisions should be at least 15 centimeters wide.

If the building has two floors, PB mandates that the cuts be placed no more than six meters apart; if the building has six floors, the cuts can be placed no more than fifteen meters apart. A few parameters are device-dependent. In order to prevent the fire from spreading from one building to another, cuts are occasionally made to divide the safe from the fire-hazardous building.

But regardless of the kind of building, if polystyrene foam or polystyrene is used as insulation, cutting must be done in compliance with the design documentation because these materials easily ignite and simultaneously highlight the gases that are harmful to humans. Mineral slabs are the only materials that can be used for insulation. The melting point of such a cut is already at 1000 degrees, a temperature that is not reached during a fire.

By using SNiP and the set of rules 293.1325800.2017, which includes the work of work and design rules, one can determine the necessary number of cuts.

Fire cutting off of window frames (fire requirement of the Ministry of Emergencies)

Fire cuts of the NVF (hinged ventilated facade) are continuous or perforated metal elements that seal the air gap around the building’s perimeter and are fastened to either the restoration or the building’s carrier wall. In the event of a fire, fire cuttings are installed to stop the burning material from the membrane from flowing through the gap and from spreading to the membrane itself.

All of the subtleties pertaining to the ventilation facade system’s operation must be taken into consideration when designing a fire cutting (note that since the cutting obstructs air flow within the layer, it is ideal for it to be perforated). The metal components of the Fireslair NVF box (hinged ventilated facade) frame the openings for doors and windows.

They are recorded using unique anchors on a construction base.

The metal components of the Fireslair NVF box (hinged ventilated facade) frame the openings for windows and doors. They are recorded using unique anchors on a construction base.

The NVF’s firebox can be constructed as a single design or as a prefabricated design with steel meshes connecting the various components.

These metal components that make up the box have the shape of a profile, with a strip lodge composed of mineral wool plates installed along the length and width of the inner cavity. Installing a fire fight system’s primary objective is to prevent fire from entering the system’s internal space in the event of a fire.

It’s also important to remember that installing the NVF firebox does not totally eliminate the possibility of a membrane fire. Generally speaking, the source of the fire is usually outside the room in practice. For instance, when doing repairs. As a result, in this instance, installing horizontal fire cuts of the NVF is advised due to the height of the building’s base with a specific step size.

Price cut-off for fire

Many people inquire about the cost of the configuration when ordering firefighters and fasteners for them because, in the case of fire cuts, the cost is contingent upon the configuration, the color of the early elements themselves, the fire cut fasteners, and the thickness of the metal used in their manufacture. Additionally, the cut-off set is supplied with thermal insulation for fire cuts in the window’s upper slope as well as around the window frames’ perimeter along a length and width of 100*100 mm.

On the ventilated facade, fire cuttings The NVF’s (hinged ventilated facade) fire cuts are made of continuous or perforated metal components that are fixed.

Fire cuttings on the facade

Fire safety is one of the fundamental needs for contemporary hinged facades. This is because even in situations where the system contains only non-combustible heat insulators, the continuous air flow involved in these designs contributes to the flames spreading quickly. As a result, "fire cuttings," which must be installed on ventilated facades in compliance with PB and SNiPs regulations, are utilized in modern construction.

Fire protection systems of ventilated facades

• protection against external influence, both mechanical and natural nature;
• high thermal insulation, and, as a result, savings on heating;
• increased service life of the facade as a result of preventing premature destruction;
• Aesthetic attractiveness of the structure.

As was already mentioned, open air circulation increases the risk of fire and speeds up its spread. Special engineering measures that drastically reduce the strength and duration of combustion, as well as the area that the fire can cover, are used in addition to non-combustible materials to minimize these risks. Cutting is one of these methods (otherwise, horizontal cuts).

The principle of cutting

These fire cuttings on the facade effectively stop flames from spreading within the building in the event of a fire as well as the impact of burning molten insulator drops outside the gap. In this instance, the ventilated facade’s required (given) air circulation is provided by the percentage of perforation of the elements under consideration.

Requirements SNIP and PB

When using polyurethane foam or polystyrene foam, which actively release toxic and combustible gas when ignited, fire fighting equipment must be used on the facade. These mineral slab structural components are employed in this instance. Such a material has a melting point of one thousand degrees Celsius.

According to SNiP 21-01-97, the quantity and number of cuts needed for a given building are determined for each individual building.

Fire cuttings on the ventilated facade – fire safety

In the event of a building fire, fire cuttings are metal structural elements designed to overlap air flows and stop the fire from spreading.

Since fire safety systems pose a risk to people’s health and even lives, they receive extra consideration when building facades and window structures are constructed. The installation of fire cuttings is a requirement for construction, and no construction object can be completed without cutting, according to the current SNiP.

The current SNiP states that these components are composed of galvanized steel with a polymer or powder coating. Because steel has a very high class of fire resistance by nature, this kind of fire brigade can fully perform the duties assigned to it.

With the help of the polymer-powder coating, we can stop steel from physically deteriorating over time when it comes into contact with the outside world.

Fire requirements for ventilated facade systems – article

Building construction and reconstruction both involve the installation of hinged ventilated facades. They require less energy to install and cost less than the specialized processing needed for supporting facial panels. Simultaneously, hinged systems must adhere to specified security standards in order to function. Installing fire cuts is especially important for ventilated facades.

They are composed of robust steel. One dependable safety measure that lowers the risk of fire is the installation of fire cuttings on the ventilated facade system. Architecture should be provided before beginning the installation of a hinged system, even during the design phase. People inside the building must be evacuated as soon as possible. Among the most crucial fire safety precautions is this one.

Correct approach to work

Selecting a heat-insulating filler is one of the primary requirements for the fire safety of hinged ventilated facades. As a result, fiberglass or basalt-based plates are utilized; frequently, they are combined. According to SNiP, specifically paragraph 5.2 of GOST 30244-94, insulation must be composed of non-combustible materials. A technical certificate that authorizes their use on the facades attests to this.

Fire cuttings on the facade norms

One of the primary specifications for hinged facades that are given nowadays is fire safety. It is impossible for non-combustible heat insulators to totally stop the flame from spreading throughout the system because of the continuous air circulation required by the design.

The result could be fire facades, a complex system of different structural and technical solutions.

Cutting is one of these methods (otherwise, horizontal cuts).

The principle of cutting

In order to prevent continuous air flow around the building, fire cuttings on the ventilated facade are metal structural elements that are fixed to the wall, the crate, or both. These slashes are:

These fire cuttings on the facade effectively stop flames from spreading within the building in the event of a fire as well as the impact of burning molten insulator drops outside the gap. In this instance, the ventilated facade’s required (given) air circulation is provided by the percentage of perforation of the elements under consideration.

Requirements SNIP and PB

The PB’s current requirements state that the spacing between the cuts cannot be greater than six meters for two-story buildings and 1.5 tens of meters for five-story buildings. This parameter is contingent upon the kind of suspended facade. Therefore, when it’s necessary to divide the components of a construction that present different fire hazards, cuts are frequently used.

When using polyurethane foam or polystyrene foam, which actively release toxic and combustible gas when ignited, fire fighting equipment must be used on the facade. These mineral slab structural components are employed in this instance. Such a material has a melting point of one thousand degrees Celsius.

According to SNiP 21-01-97, the quantity and number of cuts needed for a given building are determined for each individual building.

This kind of solution is of the greatest caliber, works well, is worth accepting, and conforms with all accepted standards.

Our team of design engineers will be able to select a solution for the production of fire fighting for a ventilated facade and glazing based on your project, providing more specific information and precise compliance.

Fire cut -off installation scheme for a ventilated facade

On a ventilated facade, fire cuts (elements) made of galvanized steel are installed along the perimeter, with a maximum of 6 meters separating each of the so-called belts. Exhaust rivets are used to secure the fasteners to the subsystem; the joint overlaps by at least 50 mm.

There should be gaps all the way around the facade to block all light. Prior to installing metal slopes in an integral box, the cuts on all openings—window, door, and specialty—should be made. In the event that a high-rise building experiences a fire between floors, all of these precautions are required to stop the fire from spreading.

Making fire cuts

The production of galvanized steel cut-offs involves the technological flexion of sheet rental, in completed elements in accordance with the customer’s specifications. Two third-party polymer group coatings are applied to steel. Steel can range in thickness from 0.5 mm to 1 mm, contingent upon the building’s design documentation. The design documentation also takes into account the cut-off configuration.

Using a variety of materials, we are able to produce any shape, design, or technological solution the customer requests in our production process. Our company’s experts will assist in preparing the technical specifications for manufacturing if needed, and they can precisely configure the components that are needed.

Common cuts are made in the shape of an equilateral or versatile corner, the details of which are determined by a particular technical task or building project. The parties differ based on the ventilated gap’s distance and the insulation layer’s thickness.

Rules for the installation of fire cutting

Install fire extinguishers all over the house’s exterior. They won’t permit fire to spread to the insulation and continue burning in the event of a fire. Use exhaust rivets on the ventilated facade brackets to secure the plates.

It is required to overlap the cut-up shit joints by 5 cm during installation. These incisions ought to be installed in every door and window aperture.

Each firewall node is developed independently on uneven surfaces and in other intricate building structures.

Simply put, settings are required if the facade is insulated with materials that can catch fire, such as polystyrene and polyurethane foam. They have the ability to catch fire instantly, and the building will quickly catch fire. Cuts made from basalt rocks or mineral slabs can help prevent this issue. Only when the temperature reaches a thousand degrees do they start to melt. Fiberglass is not used because it melts at 550 degrees. The number of cuts made specifically for each type of building structure. These components make the ventilated facade an excellent choice for facade decoration in addition to providing building protection against various issues, such as fire.

What are firefighting cuts

A metal plate with at least 0 thickness composed of thin-leaf steel is called a fire cut-off (cut).6 mm in length, minimum. It is installed with a specified height step. There are just two options available on the market for cutting. Both perforated and continuous.

Solid

When they are used, the air gap’s function is reduced to zero; in this situation, ventilation must be provided in the facade by additional measures or installed such that ventilation gaps are not overlapped. In actuality, though, such a system drastically lessens the flow of air in the NVF’s air gap.

Perforated

Aim to avoid obstructing the layer’s air flow, as this causes holes to form in them. The air exchange calculations determine the extent of the cuts’ perforation. The cutoff is mounted on brackets to the building’s loading wall, preferably using specialty rivets.

Nevertheless, no matter how deeply the cut is perforated, it will never be sufficient to maintain the required air movement velocity in the NVF’s air gap.

Fire window window

Another method, known as type fire cuts, is used to increase the fire safety of NVF systems. It is a framing of window and door openings to keep fires from starting in a ventilation gap where they will later spread throughout the system. Use metal or non-combustible mineral wool to make them.

It is essential to comprehend fire cuts in ventilation facades to guarantee the security and proper operation of contemporary structures. These incisions are essential for stopping the ventilation system from carrying a fire from one area of a building to another.

Architects and engineers can reduce the risk of fire spreading and protect the building and its occupants by carefully incorporating fire cuts into the facade design. In heavily populated urban areas with strict fire safety regulations, this preventive measure is especially important.

Building codes and standards must be carefully considered in order to implement fire cuts in an effective manner. Architects, structural engineers, and fire safety specialists must work together to guarantee local codes are followed and to improve the building’s overall resistance to fire threats.

Putting money into strong fire safety precautions, like well-built and maintained ventilation facade fire cuts, not only safeguards assets but also saves lives. It is a proactive strategy that fosters building users’ and residents’ peace of mind while supporting the safe and sustainable development of urban environments.
