What is a fire curtain?

The OLEMAT company manufactures fire curtains, which are heavy steel structures... They are lowered by a powerful electric drive.

What are fire curtains for?

When the screen is lowered, the stage portal opening is completely overlapped. In this way, the auditorium is fenced off from rooms in which there are many combustible and flammable materials. This includes stage sets and props, wooden stage structures, and more.

During the performance, there is always an increased risk of fire due to the use of a large amount of equipment, and sometimes open fire. Fire curtains prevent flames and carbon monoxide from spreading into the auditorium. Visitors are given ample time for a calm evacuation. Actors and stage personnel leave the hazardous area through other prepared emergency exits.

As practice shows, the auditorium is filled with smoke in just 1-2 minutes. The fire retardant screen prevents the spread of combustion products for different periods of time, depending on the material of its manufacture. The minimum protective period here is 60 minutes, the maximum guaranteed by the manufacturer is 3 hours.

Our company carries out the manufacture and installation of fire curtains, curtains and screens of any size. When they are installed, a counterweight system is created, which allows to reduce the efforts when raising the screen. The design of the canvas is worked out in such a way that, in the absence of a motor, it descends at a speed of no more than 0.4 m / s. This eliminates the risk of injury to people on or near the stage. The movement of the screen is warned by sound and light alarms.

To order a fire curtain, leave us a message or call the indicated phones. We will send a specialist to you free of charge for measurement and more detailed advice.

Work examples

I left a message, they called back promptly. We talked about the features different curtains(could not make a choice). Moreover, they not only helped to choose the right option for fire curtains, but also talked in detail about the various intricacies of their operation. As a result, I chose curtains OLEMAT E 180.

The order was fulfilled without delay. They did not let me down with delivery either. As a result, I have no complaints about the work performed. In general, I was satisfied. I wish the company prosperity and development.

On behalf of our manufacturing company, we would like to express our gratitude to the Fireproof Standard company. Over the years of close cooperation, we had no complaints, all situations were resolved quickly and efficiently. They have never failed with the deadlines. Subsequent service is carried out with high quality. We ordered the production of fire protection for conveyor openings and smoke curtains.

Premises of offices and warehouses, shopping centers and covered parking lots - fires in these places can cause great damage to property, health and lives of people. Therefore, they are subject to the most stringent safety requirements. Previously, in order to comply with the standards, it was enough to install a special alarm and an autonomous extinguishing system. Now it is necessary to implement a complex scheme that includes automatic fire curtains.

Scope of application

One of the main advantages of such devices is that a project from the manufacturer of fire curtains will increase the resistance of the room to fire, while not changing the layout and not carrying out serious construction works... Due to the fact that the installation does not require complex accompanying operations, usually relatively modest sums are asked for such plans.

These curtains are an effective measure against fire.

There are many benefits to curtains. They effectively protect against the spread of fire and are guaranteed to work. With general practicality, the device looks quite aesthetically pleasing and can be applied anywhere, performing the following functions:

Barrage of windows. A curtain of small dimensions is installed in the window opening itself.
Covering a large area in warehouses and industrial premises, open areas shopping centers. For this, there are canvases of impressive sizes.
Blocking of door openings and gates for which medium dimensions are suitable.

Such coated allows not only to restrict the spread of fire, but also smoke. Fire curtains can both fill the gap between fire-resistant barriers and form an independent protective unit. Much also depends on the configuration of the devices.

Fire curtains work well in conjunction with water irrigation, air retention or special breaks. The possibility of such a combination is due to the uniqueness of the structure.
In this video you will learn more about curtains:
Device Requirements
As with any other systems fire safety, there are many requirements for devices of this type. Fire curtains must match each one, have the following features:
high strength;
absence of toxic or flammable materials in any part of the device;
good indicators of chemical resistance;
very flexible fabric, resistant to destruction upon deformation;
the ability to withstand mechanical and thermal negative effects;
relatively small mass and the lowest possible thermal conductivity.

Federal law and technical regulations on fire safety requirements establish some other restrictions.
For example, the curtain can be operated closed without the need to install additional equipment. But it can also be in the open position, then the person responsible for fire safety is obliged to take care of the automatic closing mechanism in the event of a fire.
Principle of operation and composition
The main purpose of fireproof curtains is to isolate the source of ignition by preventing its spread. It also prevents the load-bearing parts of the structure from heating up and helps to reduce the spread of smoke. The first factor reduces the likelihood of a sudden collapse of the building, and the second gains additional time for the safe removal of visitors. All this is needed for a quick evacuation and avoidance of casualties.
Features of the curtains are associated with the materials used, which are impregnated with a fire retardant. Usually during production the following elements are used:
Polyester fiber. Its non-flammable properties are excellent for special curtain fabrics.
Fiberglass cloth. If particularly high fire resistance values are required from the device, it is additionally reinforced with stainless steel wire or with a protective coating.
Water supply devices. Their addition makes it possible to raise the fire resistance category of curtains by several points, without using expensive materials. Enough effective remedy, but cannot be applied on some objects.
Lifting mechanisms. Instead of mechanical devices, automatic systems are usually used. They automatically lower the roller curtain in the event of a fire. In shopping centers, curtains in stairwells can be additionally closed at night, while in warehouses and factories they are open at all times until an emergency arises.

The fire resistance class of curtains varies from El 60 to El 180, the use of a particular type depends on the specific object. At the same time, many commercial events put forward additional design requirements. After completion of the installation, it is imperative to obtain a special act, which can confirm the effectiveness and class of fire safety. This will facilitate the verification procedure in the future.
Features of good curtains
Good curtains fully meet the requirements for their fire resistance class. Otherwise, their effectiveness in localizing the source of fire and blocking the spread of fire and smoke in parts of the room is minimized. The same applies to protecting neighboring buildings from fire. Both additional funds and independent barriers of excellent quality will do well with such goals:
Protection of elevators, doors and elevator shafts.
Dividing a building into segments.
Passage protection.
Providing fire safety.
Segmenting long corridors.
Fire protection of large rooms with complex layouts.
Protection for glass roofs, domes, awnings, atriums and other fire-resistant structures.

Each curtain has its own nuances
Within the framework of projects, other cases are possible in which effective use of fire curtains is possible. Due to the typed design, different shapes and sizes do not complicate the instructions for installation and use of the device. It is based on a steel box bent from galvanized sheets with a thickness of one and a half millimeters.
The curtain's curtain is made of polyester and fiberglass, and then additionally reinforced with a thin stainless wire.

A composite material that reacts to temperature is used as a filler. When heated to 160 degrees, the canvas expands to five centimeters, which increases fire protection and the effectiveness of blocking the hearth, and reduces the spread of smoke. A cut-off tire is additionally attached to the bottom of the fabric edge. It helps the curtain to lower when unfolding, fixes the position of the canvas. After folding, the tire is hidden in a metal box.
The following indicators necessarily correspond to a good device:
Reliable construction.
Small lintel.
Electric motor with built-in battery. Autonomous power supply is necessary in case of power outages - often fires occur due to a short circuit or other wiring problems.
Automatic deployment setting when a signal is received from the remote control or from the general fire detection system.
Compact dimensions of the shoulders. This is beneficial not only during installation, but also for the operability of the structure.
The simplicity of the device. How simpler design, the easier it is to maintain. In addition, it reduces the likelihood of breakage and also facilitates possible repairs.

When there is no need for protection, the curtain structure is simply wound on the shaft by an electric mechanism. When folded, the device does not interfere with moving around the room. The curtain also unfolds with the help of an electric motor, and this happens after receiving a remote alarm. Usually the unfolding mechanism is included in common system fire support.
Main varieties
The range of modern fire curtains is quite rich. Among them are the most effective solutions suitable in most cases:
Blades with El60, El90 and El120 limits without water irrigation. They are well suited for large shopping malls and other similar establishments. This is a great option for fire safety in areas where water can cause a short circuit.
Categories 60 to 180 with water irrigation. More effective option in cases where water will not cause collateral damage.
Horizontal curtains. They are mounted in the openings of the floor and ceiling. Well blocks fire and smoke from spreading to other floors.
Accordion curtain. Interesting solution with a non-standard layout.
Window protection. Will not allow the transfer of fire to an adjacent building.
Smoke protection curtain class El120. It features a special smoke exhaust system that removes combustion products and helps to safely evacuate people.
Fire retardant membrane. It is somewhat less effective, but it is made to order with arbitrary dimensions. It can block even the largest openings.

For conveyor openings, special barriers are produced.
The nuances of installation and purchase
With the purchase of curtains from the spread of a fire, there should be no difficulties. The price on the Russian market is affordable for all organizations and private entrepreneurs interested in installing such tools. However, in addition to purchasing the device itself, a fire safety plan must be ordered. Often best projects make the manufacturers themselves, because they know all the nuances of their own products. Effective implementation of the device's functionality is possible only if all installation rules are observed.
Requirements apply not only to the curtains, but also to the room itself. The device will effectively perform its function only if the following characteristics correspond to the opening:
The fire resistance of the material used for the construction of the opening exceeds the minimum indicator.
Possibility of stable and rigid fastening of the curtain structure.
Equal planes required for mounting the housing and rails.
Lack of any communications.

If the opening does not correspond to at least one item from the list, then it is impractical to install fire protection. Otherwise, the place of installation depends on the preferences of the customer and the features of the layout. You can install curtains:
In the opening on the ceiling.
To the surface of the wall.
Suspended mounting. The box is held in place by threaded rods and mounting profiles.
Fastening to beams.

Other features, including specific models and options for their installation, are best checked with a specific manufacturer.

Modern fire safety systems are characterized by a certain complexity. So, when putting an object into operation, they try to provide it with several fire protection elements to minimize damage in the event of a fire and its further development into a fire.

The most versatile elements of complex fire protection systems are fire curtains and curtains. These are special fire-resistant barriers, the task of which is to localize the flame, and often prevent the spread of smoke and other combustion products over the territory (smoke-tight fire curtains and curtains, curtains and screens).

Structurally, fire curtains and curtains are a canvas, which is fixed on the shaft on one side, and a heavy cut-off rail is located on the other. The canvas moves along the guides, which can be fixed on the sides of the opening, or on any other flat surface. Part of the design of fire curtains and curtains, curtains and screens is a protective box, which is attached over the shaft and protects the shaft and the canvas laid on it from physical damage, and also gives the entire structure an aesthetic appearance.

One of the important elements possessed by fire curtains and curtains is a rotating drive shaft, on which the curtain is laid. As a rule, the drive is made as a shaft or intra-shaft with a reversible motor, and it can be connected both to a regular network and to a network with a reduced voltage, up to 24 volts.

Fire resistance of fire curtains and curtains.

Fire curtains and curtains, curtains and screens, as well as fillings of fire-resistant barriers - gates, doors, windows, hatches, valves (see more details about the classification of fire-resistant barriers and infills of fire-resistant barriers in this material) Federal Law 123-FZ "Technical Regulations on Requirements fire safety "regulates the limit states that determine the limit of fire resistance of a fire barrier / filling of a fire barrier. In terms of fire curtains and curtains, curtains and screens, 123-FZ "Technical Regulations on Fire Safety Requirements" sets the fire resistance limit:

for fire-resistant curtains and curtains, curtains and screens, as well as doors (excluding doors with glazing of more than 25% and smoke and gas tight doors), gates, hatches, valves for loss of integrity and loss of thermal insulation capacity due to reaching the surface temperature limit (critical) values - EI 15, EI 30, EI 60 depending on the type;

for fire-resistant smoke and gas-tight curtains and curtains, curtains and screens for loss of integrity, loss of thermal insulation capacity due to the achievement on the surface of the limiting (critical) values of temperature and / or limiting (critical) values of the heat flux at a regulated distance from the structure / barrier / filling of the barrier, and smoke and gas tightness - EIWS 15, EIWS 30, EIWS 60 depending on the type.

The EI or EIWS parameters determine the time after which the manifestation of one of the limit states violations of fire resistance. So, for example, the Latin letter E denotes the loss of the integrity of the fire-resistant barrier / filling of the fire-resistant barrier, while E 60 tells us about the time after which this can happen. The Latin letter I denotes the loss of thermal insulating ability due to the achievement of the limiting (critical) temperature values on the surface, the letter W - the loss of the thermal insulating ability due to the achievement of the limiting (critical) values of the heat flux at a regulated distance from the structure / barrier / filling of the obstacle, the letter S - loss of smoke and gas tightness, and the EIWS 60 value indicates that the heat insulating ability of curtains and smoke and gas tightness can be violated after 60 minutes according to one of the limit states.

Fire curtains and curtains have high fire resistance rates because a special material is used in the manufacture of the canvas, as a rule, glass or silica fiber, due to which the canvas not only has the fire resistance regulated by 123-FZ, but also remains flexible and at the same time durable.

Fire curtains and curtains can be used to solve the widest range of fire engineering tasks - to protect openings in which windows and doors are installed from materials that support combustion, to fence emergency exits, stairs, platforms, etc. a cube that allows you to completely localize a particular area of the territory, as well as protect it from the spread of smoke and other toxic substances harmful to human life and health.

Fire curtain

A stage covered by a fire curtain

Fire curtain (fire curtain, fire screen, "iron curtain")- fireproof smoke-tight construction with a rated fire resistance limit, made of non-combustible materials(metal, reinforced concrete, refractory fabric) and lowered in case of fire to separate the stage from the auditorium. Serves to prevent the spread of fire and combustion products during the specified time.

Fire development

The stage and the adjoining rooms have a large amount of combustible materials (construction of the stage table, hold, grate bars, combustible decorations and props). The fire load in the stage complex reaches 200 ... 350 kg / m² and has a highly developed surface. : 274

If a fire breaks out on the stage when the portal opening is open and the smoke hatches are closed, then there is a threat of fire and smoke spreading into the auditorium. Practice shows that in such conditions the auditorium is filled with smoke in 1 ... 2 minutes. : 275 In the absence of a fire curtain, the intensity of the heat radiation becomes dangerous for spectators already after 30 ... 40 seconds of fire. : 164 With a decrease in the capacity of the hall, the time of occurrence of fire hazards decreases and the danger for spectators appears earlier. : 165

Design

Spectacular enterprises with a capacity of 800 seats or more are usually of architectural value. In such buildings, the functional purpose of the curtain is not only to ensure the safety of evacuation of people, but also to preserve the building. In buildings of no architectural value, it is possible to limit functional purpose curtain ensuring the evacuation of people and preventing the spread of fire into the auditorium before the combat deployment of fire departments. : 165 In the halls of cultural institutions with a capacity of less than 800 people, where there is no fire curtain, the portal opening must be protected by a deluge installation (water curtain).

A red line should be drawn on the stage board to indicate the border of the fire curtain. Decorations and other decorations for the stage should not protrude beyond this line. At the end of the performance (rehearsal), the fire curtain must be lowered. The fire curtain should fit snugly against the stage board with a sand shutter (elastic cushion). The lifting and access mechanism must provide a curtain lowering speed of at least 0.2 m / s.

Wikimedia Foundation. 2010.

According to SNiP, fire curtains must be present at all industrial and manufacturing enterprises, as well as in crowded places (shopping centers, offices, train stations, museums, theaters, etc.).

These products are designed to contain fire and divide the room into compartments in the event of a fire. The need for their installation is regulated by Art. 37 and 88 FZ No. 123 of 2008.

Purpose of fire curtains

Fireproof roller blind necessary to stop the spread of fire and smoke.

The installation of such products increases the time that the premises are engulfed in fire, so that people can evacuate from a dangerous place.

Varieties

Externally, fire curtains look like fabric roller blinds that are lowered when a fire breaks out.

The main types of fire curtains are fire and smoke curtains. There are designs for irrigation.

Such products provide irrigation in the form of a water curtain in front of the curtain. The average water consumption is 7 - 7.5 liters per minute per 1 sq. m. canvases.

Non-irrigated products are installed in rooms where there is a need for a barrier against toxic and harmful fumes.

The fire retardants are made of fiberglass reinforced. Such products can withstand the spread of fire for 2 hours.

Smoke Screens

Smoke blankets are required to control the direction of the smoke flow.

The main purpose of the curtain is to stop the spread of smoke throughout the room and the penetration into adjacent rooms... They are made from a special woven fabric.

Smoke blankets are installed in blocks. They protect emergency exits, but at the same time do not impede the passage of people through them.

What is the difference

Flame retardants when lowering are designed to fill openings and close the path of the flame, that is, to completely block the spread of fire.

Smoke shields are lowered both completely and not completely, that is, to the height of the smoke layer.

The second difference between the fire retardant cloth is that it may not have side guides.

Manufacturing material

Fireproof curtains are made of innovative technological material that can withstand the effects of fire for up to 3 hours.

The canvas is safe for human health, does not emit toxic materials and vapors when smoldering and burning. The material for the manufacture of canvases is impregnated with a special fire retardant compound.

The main constituents of matter:

Fiberglass cloth.
Polyester non-flammable fiber.

The thickness of the fabric ranges from 3 to 7 mm. The heat resistance of the material used for the manufacture of fire retardant cloths can reach 1,100 degrees.

Products with fire resistance class EI - 120 are reinforced with stainless wire. Some models use flame retardant fibers instead of flame retardant fabric.

Dimensions (edit)

All structures operating in automatic mode consist of the following elements:

Box.
A web wound on a shaft.
Guide tires.
Bottom plank.
Electronic part.

The electronic part contains the control unit for the fire curtain: engine, battery and control system. Today, canvases are most often made to order based on the size of the room.

Dimensions of fire curtains:

The maximum width is 21,000 mm.
The maximum height is 8,000 mm.

Standard dimensions of the box where the shaft is located:

Height - 260 mm.
Depth - 211 mm.
Width - up to 21,000 mm.

Standard dimensions of guide rails:

Height - up to 8,000 mm.
Depth 64 mm.
Width - 112.5 mm.

Control

Distinguish between curtains with automatic and mechanical control. Today, the most commonly used designs are with automatic triggering.

When turning the web, a cut-off tire is triggered, which provides tension to the fabric and full contact with the floor. Fire curtains are controlled by remote control panels.

To operate in automatic mode, the structure must be connected to the fire alarm system. In the event of a fire alarm, the canvas opens itself in about 10 - 15 seconds.

Automatic curtains unfold on their own when the room temperature rises.

Special thermal sensors are installed in the structure, which, when the temperature rises, turn off the electromagnets holding the tissue. The material sinks under its own weight.

If the curtain is with water spray, then it turns on automatically. Water is essential for the cooling effect. Water irrigation present in curtains with fire resistance class EI 45 and 60.

According to the standards, for the normal functioning of the product, it must be checked regularly, it is necessary to monitor the battery charge level.

Basic rules for installing the structure

Structures are installed on:

Gates and doorways.
Elevator gates.
Window openings.
Ceilings.

Installation is also possible on the facades of buildings, provided that they are placed close to each other.

Minimum installation dimensions:

The main space is 25 cm.
Lateral space - 10 cm.

The installation of a fire curtain should only be carried out by a qualified specialist who is licensed by the Ministry of Emergencies. The structure must be connected to the system of fire detectors and alarms.

Service

Fire curtains should be serviced at least 2 times a year.

Maintenance involves checking:

The performance of the product.
Curtain fabric for damage.
The possibility of breaking the structure.
The management block for performance.

After verification, inspection certificates are issued.

Technical requirements

The main technical requirements for fire-fighting sheets:

Thickness - not less than 0.7 mm.
The weight of the matter is 0.7 kg per 1 sq. m.
The weight of the entire structure is 30 kg per 1 running meter of the blade width.
Engine power supply voltage - 24 V.
Width - no more than 20 m.
Height - no more than 8 m.
The screen lowering speed is 0.15 meters per second.
The service life is 70,000 operations.

The design must have a button to raise the screen when people are evacuated from the premises. All products must be with certificates of conformity.

The need for a residential installation

Many are interested in the question, is it necessary to install fire curtains on windows in living quarters? Experts assure that if people have such an opportunity, then it is better to do it.

If finances do not allow installing these structures on all window openings, then it is better to mount the product in the window opening in the kitchen.

This room is most likely to cause a fire. Curtain fires are common.

Conclusion

Fire curtains are an essential element in fire safety. They protect against the spread of fire and smoke, do not reduce space, harmoniously fit into any design, without disrupting the complete picture of the interior. Structures are made individually for each enterprise or premises, but you can also buy ready-made ones.
