Which roller shutters are better to choose. Comparison of roller shutters according to the main parameters. Roller shutter control and how to install them

In conclusion, check out a few tips that will ensure many years of operation of your roller shutters without breakdowns and failures:

• before you raise the roller shutters, make sure you have unlocked the lock.
• do not make sudden movements when raising the roller shutters on the mechanics.
• icing on roller shutters should be removed very carefully so as not to damage the protective layer on the slats and guides.

Recently, the question has become relevant: "How to choose roller shutters for a summer residence or a country house?". This device protects from prying eyes, from robbers, from sunlight or simply from stones and bottles.

What are roller shutters?

If the house becomes non-residential for some time, then it is better to secure it from all kinds of damage and penetration. Roller shutters for summer cottages are a great option, but what is it? This is a mechanical device that performs the protective functions of windows and doors. Roller shutters are easily removed into a box or a special cavity, they are able to twist the canvas into a roll. The device can be driven by an electric motor or a mechanical drive.

Roller shutters have a number of advantages:

• very compact;
• aesthetic in appearance;
• easy to maintain and maintain;
• do not damage the facade of the building;
• provide sound insulation.

This device can be installed on (in) any openings, they are convenient and versatile in use.

What are roller shutters made of and which ones are better?

Roller shutters are made from two materials:

• made of aluminum - they are good because they are light in weight and very compact;
• from metal - a galvanized sheet is used, which allows the device to be a strong protection, but also more expensive in price.

Both options look great on the home, but they differ slightly in quality, cost, and reliability. Therefore, before choosing a roller shutter for a summer residence, you need to find out what material the device is made of.

What to ask about

In order not to make a mistake when buying products, you need to consider many factors. It's not just the material and price.

Tips on how to choose the right roller shutters for a summer residence:

1. First, a lot of attention should be paid to technical features. For the convenience of the user and a longer service life of the device, it is better to equip it with an electrical system. It is controlled by a remote control or a button. All windows can be connected to a single system and simultaneously open or close.
2. Secondly, the roller shutter manufacturer is also an important issue - a separate model has its own characteristics.
3. Thirdly, it is advisable to ask for quality certificates for the goods.
4. Fourthly, when choosing, take into account the interior of a summer house or house, so that the result is not only reliable protection, but also a harmonious look.

Components and installation of roller shutters for summer cottages

Roller shutters consist of three parts:

• box (inside it there is a shaft and side guides);
• protective rolled fabric;
• side guides.

Roller shutters by type of installation are:

• built-in;
• overhead.

The first type is more reliable and practical. Roller shutters are installed in a window or doorway. They cannot be bent or torn off, they can only be approached when raised. Otherwise, you just have to disassemble the wall.

Overhead roller shutters have one drawback - guides are visible that can be turned out or broken (albeit with great effort).

It is best to plan the installation of this device at the design stage of the building. The dimensions of the box depend on the height of the window or door opening. If in the house, it is planned to install roller shutters for giving with an electric drive, then it is worth laying the appropriate cables in advance with its connection to the windows. But if the choice was made in favor of mechanical control (manual), then it is better to provide a place for withdrawal inside the building so that the finish does not deteriorate.

Additional benefits of roller shutters

Roller shutters for cottages and country houses look great on window or doorways. It is important that the color gamut of the device is quite wide. For example, roller shutters are white or brown, gray or beige. Also, at the request of the customer, the basic colors can be expanded, the list of shades reaches up to 150 colors.

This device saves heat by storing it. The advantage of roller shutters for summer cottages is their adjustment. The mechanism can be fully opened or ajar to the desired distance.

For what purpose do people put roller shutters for a summer residence?

The main purpose of roller shutters on a house that is temporarily left without owners is to protect the premises from thieves and robbers. A device made of durable material is quite difficult to hack, the whole process is loud and long.

Already a large number of people have used roller shutters for summer cottages. Consumer reviews are mostly positive. The obvious advantages of the device are noted:

• a beautiful and unobstructed view from the window (looking through the bars is not a very pleasant sight);
• ease and several ways of control (manual or automatic);
• strong protection against robbers.

How to choose roller shutters - video

In this article we will talk about roller shutters on windows, how to choose and manage. Characteristics and operating rules for the use of roller shutters.

Ever since the beginning of the 90s, it has been customary in the countries of the former Soviet Union to protect their houses, apartments and dachas from the outside world with external doors sheathed with steel sheet and equipped with reliable locks.

But in addition to the entrance doors, there are also windows, which are much more than doors - what to do with them?

In those years, this was solved in a simple way, by installing various steel gratings on them to protect themselves from intruders.

Until today, one can observe many “decorating” window openings of houses and apartments, at that time fashionable and necessary lattice barriers that terrify and sarcastic laughter among tourists from Europe.

They cannot understand how it is possible to live behind a window bar and feel comfortable.

Of course, a person gets used to everything and can continue his life in such conditions, and look at the world through bars.

And you can approach this issue differently and solve the issue of your safety in another way - install roller shutters on window openings.

What are window shutters?

Particularly acute questions about the safety of their homes were relevant in the Middle Ages.

This applied to both urban and rural areas.

In those days, with the onset of darkness, gangs began to operate on the streets, who were looking for easy money. The night guard was either bribed by bandits, or was in small numbers and was not able to ensure the peace and safety of the property of its citizens. They tried to mainly patrol the areas where the aristocrats and the rich lived.

That is why on the windows of the houses of people of that time there were massive external shutters, often iron-bound, and they were closed at night, with a lock.

Over time, outdated shutters began to be replaced with double-leaf blinds. They allow you to perform a dual role - they protect windows from the penetration of burglars, complicating their design, and reduce the penetration of sunlight in the daytime.

Modern roller shutters for windows, consist of a web of profiled lamellas, interconnected by locks of a special design.

Roller shutters move along guides, which makes it possible to move them freely up and down.

When the roller shutter is lifted, the lamella sheet is wound onto the shaft in a roll, hidden under a protective cover, partially or completely opening the window opening.

If the shutters are closed, penetration into the house is very difficult, since the gaps between the slats are very small in order to insert a crowbar between them to break it. In addition, its use will cause quite a loud noise and wake up the owners and their neighbors.

Roller blinds have become the perfect means of protecting windows from heavy rains and gusty winds for residents of our planet living in difficult climatic zones. Where the power of natural disasters cannot be held by ordinary hinged shutters and double-glazed windows.

The device and principle of operation of the roller shutter is the same as in roller shutters.

The slats that form the roller shutter web can be aluminum, steel and plastic. Inside the cavities of their profile can be filled with polyurethane foam or be hollow.

Lamellas are made in two ways - by extrusion and roller rolling with filling the void with polyurethane foam.

Although it can be noted that the filler still provides additional sound and heat insulation properties, they do not play a special role during the operation of roller shutters.

The crimping roller press makes it possible to obtain lamellas that are light and resistant to bending. They are used to assemble steel lamellas for roller shutters.

A seamless extruded profile, with a thickness less than that of a profile made by the rolling method, but with greater rigidity due to thick walls, as well as stiffening ribs inside.

Extrusion-made slats come with and without internal cavities, while their cavities are not filled with polyurethane foam.

In the profiles of PVC lamellas there are internal chambers, which can be from 2 to 8, they are separated from each other by stiffening ribs filled with air.

The roller shutter curtain formed by plastic lamellas has low operational data compared to steel and aluminum lamellas.

As part of the roller shutter leaf, a plastic profile is subject to expansion due to high summer temperatures. This leads to its frequent falling out of the guide systems due to the weakening of the rigidity of the structures and gusty wind.

In addition, the surfaces of the plastic sheet during operation acquire a lot of mechanical damage. They are displayed in the form of small scratches and minor abrasions caused by the winding of the roller shutter curtain on the mechanism shaft when they are raised.

Dignity, roller shutters made of plastic, have one thing - this is a lower price than that of aluminum and steel models.

Since aluminum is stronger than plastic and much lighter than steel, they are not afraid of corrosion and therefore can last at least 5 years.

Aluminum roller shutters are very popular, although they are inferior in strength to steel roller shutters.

This is due to the low weight of the aluminum web and requires little physical effort to move it with manual control and a low-power electric motor with electrical control.

If there is a need for an increased level of window protection, it is worth using roller shutters with an aluminum sheet made of extruded lamellas, as already mentioned, they are more resistant to external influences due to the presence of internal stiffeners.

Roller shutters, in which the canvas consists of steel lamellas, are the heaviest and an electric drive with a powerful engine is needed to control them.

The strength of the steel leaf is superior to that of aluminum roller shutters, however, despite the applied layer of powder or polymer

paint, on steel lamellas, with minor damage, a corrosion center forms on its surface.

Such shutters need daily care to track damage to the paintwork and restore it immediately.

If you do not follow this rule, the service life

steel roller shutter will not exceed 3-4 years.

The shaft on which the roller shutter is wound is made of galvanized steel, hollow inside, has an octagonal or rounded shape. All other parts of the roller shutter are made from the same material as the slats, i.e. aluminum, steel or plastic.

Roller shutter control and how to install them

The stores offer customers two types of roller shutters - built into the wall above the window opening and external (overhead).

The most common and simple installation of structures is with an external casing, since it does not require facade reconstruction of the building. Roller shutters of various standard sizes make it possible to choose the desired width of the shutters for any window opening.

Roller blinds with a built-in casing are distinguished by their invisibility when the curtain is raised. However, the installation of such shutters is permissible only when preparing openings for them, even at the stage of construction or major reconstruction of the building.

If we consider from the point of view of what is better to protect the premises from penetration into it, then it should be noted that built-in roller shutters are preferable.

Hacking such a structure is more difficult than a consignment note, since the casing with the shaft and their guides are hidden in the wall of the building and it is impossible to get to them without destroying part of the wall.

How are roller shutters controlled?

Roller shutters have mechanical control, which is divided into spring-inertial, cardan, tape and gear (cable), and also has several more subspecies.

The easiest way is tape control. Closing or opening the roller shutter curtain occurs by loosening or pulling the tension tape, which is brought from the casing into the room.

Such control is used for roller shutters assembled from light aluminum lamellas with a small area of ​​the web and weighing no more than 15 kg.

The gear control of the shutters differs from the tape control in that it uses a cord instead of a tape.

The web is moved by rotating the handle, which is inserted into the gearbox of the structure, on which the cord is wound during rotation.

This design allows you to raise and lower the roller shutter curtain weighing 15-20 kg.

A subspecies of this control method can be a cord mechanism; instead of a cord, it uses a steel cable, which makes it possible to increase the weight of the roller shutter curtain up to 60 kg.

Cardan control of the roller shutter leaf is also performed by turning the handle, only the gearbox is located on the inside of the window at the same level as the casing installed outside.

The transmission of torque from the handle is carried out through a long metal rod (cardan).

Such a subspecies of roller shutter control is a gate mechanism, it is activated using a long gate.

To raise or lower the canvas, it is necessary to insert the end of the gate into a special socket on the casing of the structure and rotate the handle located at its end.

Permissible maximum web weight in both of the above control options is 35 kg.

The roller shutter can be raised and lowered without special devices if a torsion spring is installed on its shaft, the task of which is to balance the weight of the curtain - necessary to give the curtain a slight acceleration in a given direction and, accordingly, it will rise or fall.

The mechanism is set up when installing the roller shutter with which it is equipped.

The admissible maximum weight of a movable cloth is 50 kg.

For automatic control of the roller shutter web, a small electric motor is used, which is located inside the casing next to the shaft.

For activation, a rotary, push-button, or touch switch and a remote control are used.

Usually roller shutters are equipped with electric motors, the weight of which is more than 35 kg, but installation on curtains with less weight is also allowed.

The advantage of automatic roller shutters is their ease of use.

But there is also a drawback - in the absence of electricity, it will not be possible to open or close roller shutters.

The canvas in the closed state is fixed with the help of special latches or a special lock with a key.

How to choose roller shutters

Models with plastic and steel lamellas do not make sense to consider because of their unprofitable use.

Some have a weak degree of protection, while the latter are highly susceptible to corrosion.

On the Russian market, roller shutter assembly companies use lamellas made in Germany and Italy.

Operational rules for roller shutters

First of all, it should be noted that the opening and closing of the canvas is allowed only when using the mechanisms intended for these purposes, without using excessive physical force.

If the efforts applied when controlling the blade are not enough and it is not set in motion, then it is not necessary to pull the handle with more force, there may be a malfunction of the mechanism and the intervention of a specialist is necessary to carry out repairs.

To avoid damage to the control mechanism, before each opening of the roller shutter make sure that the lock installed on the lower lamella is in the “open” position.

In the winter season, roller shutters can freeze to the rails. In the case of such freezing, they must be carefully examined at the junction of the web with the guides, and if there is frost, tap on the perimeter of the web with a hammer with a rubber impact head. And after the manipulations done, you can try to bring the shutters to the open position.

Periodic cleaning of the roller shutter curtain from accumulations of dust and dirt is carried out using a soapy water solution and a soft flannel cloth, you can also use ready-made cleaning products that do not contain abrasive particles.

Roller shutters are blinds made using two guides and a roll of metal plates fastened together. They are installed in door, window, and garage openings. The system of roller shutters allows you to protect the premises from the intrusion of outsiders, from negative natural factors, noise and light. The structures are installed from the outside of the opening, due to which they prevent the breaking of glass and the penetration of intruders. Let's talk about these systems in more detail.

Design features and scope of roller shutters

Standard window and garage shutters open vertically by rolling up or down the protective sheet. In addition to standard rectangular designs, there are asymmetric options that can repeat the triangular or arched shape of window openings. Inclined systems are used to protect various glass structures (e.g. winter garden roofs). Metal roller shutters are most often installed at the cash registers, on the windows of the first floors of residential and office buildings, and are also used as office partitions or decorative elements.

The main functions that roller blinds perform include:

• protection against breaking and entering, as well as from prying eyes;
• protection from negative environmental factors and sunlight, maintaining an optimal microclimate indoors, for example, in greenhouses or indoor arboretums;
• cost reduction for electricity by keeping the heat in the room during the cold season and keeping cool in the summer;
• partial soundproofing and protection from dust or sand;
• aesthetic function: outdoor or built-in roller shutters can be used as facade decoration elements.

All ready-made roller shutters have a similar design, which includes a roller shutter profile; a shaft on which the web is wound; protective box; guides and side covers, providing rigidity of the box. The slats that form the profile can be aluminum, steel or plastic. The most popular are non-corrosive and durable aluminum lamellas.

According to the type of profile, protective roller shutters are:

• roller rolling, providing high-quality heat and sound insulation, as well as being lightweight;
• extruded, characterized by increased strength.

Advantages of roller shutter systems

The main advantages of roller shutters over other types of protective structures (metal gratings, doors, gates, etc.) are:

• in reliable glass protection: glass covered with roller shutters is almost impossible to break (while traditional grilles do not protect windows from damage);
• in lightness and pleasant appearance: unlike massive doors, shutters or gratings, good roller shutters do not spoil the appearance of the facade of the building and do not create additional load on the structures;
• in ease of use: such designs practically do not require repair and preventive maintenance;
• in safe operation .

Varieties of roller shutters are determined by the specific goals and objectives of their use, in connection with this, the advantages of individual roller shutter systems may vary depending on the type.

Roller shutter types

Mechanical and automatic roller shutters differ in their design features, dictated by the conditions of use and control method. In terms of purpose, the following types of roller shutters are distinguished:

1. Roller blinds on doors, windows and glass roofs. They are in demand both by companies (especially retail outlets) and individuals. Roller shutters on the door or window provide reliable protection of the room and at the same time are characterized by a long service life, safety and pleasant appearance.
2. Roller shutter garage doors. They differ from window roller shutters in that they are made using stronger and wider profiles. Such designs are suitable for garages, warehouse and industrial premises, as well as for retail outlets and entertainment centers.
3. Protective grilles with holes of various shapes. They are characterized by a stylish and attractive look, making them ideal for protecting private households, offices, restaurants, shops and parking lots.

Roller shutters can be operated manually or electrically. Mechanical systems are equipped with spring-inertial, tape or cord mechanisms. Such structures are installed in rooms with several windows of compact size.

For rooms with a large number of windows, the best solution is to install automatic roller shutters, which allow you to operate several roller shutters at the same time. In this case, standard key switches or remote controls can be used.

Installation work

Only experienced professionals can install roller shutters correctly. Installation work includes inspection of the installation site of the structure, measurements, and, if necessary, additional preparation of the window opening. At the next stage, installation and, in some cases, finishing works are carried out.

Anti-vandal shutters are made individually for each opening, so it is extremely important to take measurements correctly (especially for asymmetric structures). Installation is carried out outside or inside the opening in one of the following ways:

• with a protective box at the top of the opening;
• with a protective box at the bottom;
• SO-shaped, with a protective box mounted on top at an angle of 10–45°;
• for glass roof: sloping shape, with a protective box at the top or bottom, set at an angle of 15–70°.

Finishing work is carried out after installation is completed only in rare cases. Installation of structures can be carried out at any stage of repair work (including after their completion). The only exception to this rule is internal roller shutters, which are equipped with a built-in box. Installation of such structures should be carried out at the design stage. In the door or window opening, it is necessary to provide space for the installation of the box, which will then be covered with finishing materials. Hidden roller shutters are installed in cases where it is important not to disturb the aesthetics of the facade.

The cost of protective structures

One of the main questions that interest people who want to order roller shutters is the price of manufacturing and installation. The final cost is determined primarily by the selected options for roller shutters, the manufacturing company, the region in which the product is purchased, and some other factors. So, the price of structures and their installation is affected by:

1. Profile type. The cost of aluminum with a soft filler and a lamella width of 45 mm is about 3000 rubles/m 2 , aluminum with increased strength is 4500 rubles/m 2 . The price of garage doors is about 4000-5000 rubles / m 2.
2. lock type(the cost can vary from 300 to 2000 rubles.) and control mechanisms. The most expensive option is a roller shutter with a centralized remote control, and the cheapest is a mechanical device with an induction cord.
3. Electric drive type(for designs with electronic control). The cost of the device can vary from 7,000 to 20,000 rubles.

So, you can buy roller shutters for a home window with a size of 1500 x 1500 mm with a standard Ar 45 profile and a manual drive at a price of about 8,000–15,000 rubles. Gates with a size of 3000 x 3000 mm with a garage profile AG 77 and an electric drive will cost the customer 50,000–80,000 rubles. The cost of installation is about 20-25% of the price of the installed product, while the final amount will not be less than 2000-4000 rubles. The delivery service in Moscow starts from 1000 rubles.

To draw a conclusion about which roller shutters are best suited for a particular room, you need to decide on the conditions for their use and purpose. Then you should take measurements (determine the width and height of the opening in millimeters) and decide on the type of installation.

The easiest way to install internal and external roller shutters is by way of overhead method. In addition, such structures do not close the glass. Their disadvantages include the insufficient strength of the installation (with due effort, the box can be torn off the wall) and the increased size in comparison with the parameters of the window opening. So, when calculating the dimensions, 120 mm will need to be added to the width of the opening, and 200 mm to the height.

The installation of such systems on the opening is relevant for residential buildings and private garages, as well as for premises already in operation.

For buildings that require increased protection against burglary and penetration, structures are designed that are mounted in an integrated or combined way. Installation inside the opening eliminates the possibility of breaking the box by intruders. In addition, such systems do not spoil the facade of the building, which is important for shopping centers and offices. The main disadvantage of this type of installation is that the protective box partially closes the window (by about 15 cm).

After choosing how to install the system, you need to decide on the preferred profile. For home, garage and office, in most cases, lightweight aluminum or lattice profiles are purchased. For warehouses, shopping centers and banks, durable anti-vandal and garage structures are relevant.

The next step is to choose the type of control. The spring-inertial roller shutter drive is used in structures weighing up to 100 kg. For systems up to 10 kg, you can purchase an inertial cord, and for roller shutters up to 30 kg, gear and cardan mechanisms are suitable.

Electrical control can be by means of an electric drive with manual lifting or remote control. In rooms with a large number of window and door openings, control can be carried out from a single electric drive with an automatic control system.

The final step is the choice of a locking device. The simplest option is considered to be side latches and locks in the lower bars. For devices with electric control, top locks and electric locks with keys are often used. After all the necessary parameters are determined, you can proceed to placing an order.

Thus, roller shutters provide reliable protection of the premises from intrusion and negative natural factors. They contribute to energy saving and perform an aesthetic function. The indisputable advantages of such systems include their reliability, durability, reasonable cost and unpretentiousness in maintenance.

Recently, in our country, people often equipped exterior doors in their living quarters, which were previously sheathed with durable steel sheets. However, you can also enter the room through the window. Therefore, special steel gratings are used to ensure safety. Today, roller shutters have become very popular. These devices require special attention, so this article provides detailed information about them. Qualified specialists in the field of construction talk about the types of roller shutters, the advantages and disadvantages of these devices, as well as the materials used for manufacturing.

What are roller shutters

High-quality roller shutters are used to protect window openings from showers, strong gusts of wind. High strength is a sought-after quality for homeowners living in relatively difficult climatic conditions. If for some period no one lives in the house, it is advisable to protect yourself from possible damage and unwanted intrusions. Roller shutters will serve as a wonderful means of protecting a country house. Such mechanical devices remarkably perform the protective functions of window and door openings. Such roller shutters are easily assembled into a specially equipped cavity or drum, thanks to the ability to roll into a roll. To drive such a device, you can use an electric drive or a conventional motor.

Consider the main advantages of roller shutters:

• Compactness;
• Aesthetic appeal, good external qualities;
• Ease of care and maintenance;
• The appearance of the entire building does not deteriorate;
• Good soundproofing.

Such devices can be equipped with different openings, which are considered universal and very convenient to use.

Roller shutter design

Conventional window or garage fittings can be opened vertically by rolling the protective sheet into a roll. In addition to the usual rectangular products, asymmetric options are installed that reproduce the triangular or arched shapes of window openings. Tilt mechanisms are used to provide protection for a variety of glass structures such as winter gardens and roofs. Metal roller shutters are most often installed at the cash desks of trading floors, window openings on the first floors, in offices or residential premises. Quite often roller shutters are used as office partitions, or elements of decorating the exterior of a building.

The main functional features include:

• The ability to protect against penetration, hacking, or extraneous curious people;
• Providing protection from destructive natural factors or too bright sunlight. Ensuring a normal microclimate in a room, a greenhouse or equipped arboretums;
• Reducing electricity costs by saving indoor heat in the winter season and providing coolness in the summer heat;
• It can be used as an element of the aesthetic design of the building. Roller shutters help to decorate the facade well.

All roller shutters are assembled according to the same principle and consist of a sheet and a roller profile, a shaft on which the sheet must be spun, as well as a special box for protection, side covers with guides that increase the rigidity of the box and the strength of the structure as a whole. The lamellas, thanks to which the profile is formed, can be made of plastic, aluminum and steel. The most popular are non-corrosive and most durable aluminum lamellas.

According to the type of profile, protective roller shutters are divided into two subcategories:

1. Roller rolling, contributing to increased sound insulation and heat saving, characterized by increased lightness.
2. Extruded high strength products.

How to choose the right roller shutters

First of all, you need to decide on the purpose of the roller shutters. Each buyer should understand well what he is going to use such elements for. Therefore, the standard produced roller shutter systems are divided into several subspecies in accordance with the protection indicators:

• P1 - high sound insulation, prevention of dust, wind, it is invisible what is in the room;
• P2 - performs a similar function, but in large areas up to about 16 square meters. m.;
• P3 - in addition to all of the above, they can provide protection against hacking for about 20 minutes;
• P4 - Protection against natural factors and hacking for about 25 minutes;
• P5 - the duration of protection against hacking can be 35 minutes;
• P6 - 50 minutes;
• P7 - full protection against penetration.

Qualified specialists will be able to determine the most appropriate protection class for each individual example.

Also, when choosing suitable roller shutters, you need to pay attention to the area of ​​\u200b\u200bthe product. The dimensions of the window opening are selected with a special type of profile. Experienced specialists can go to the right place to take measurements, and then make a suitable design of roller shutters according to an individual order.

Products also differ in the type of control, mechanical and electric drives are used. Manual systems are much cheaper, but their use is possible only in some situations. Electric mechanical elements cannot always cope with heavy roller shutters installed on garage doors or other large structures. For all types of control, certain restrictions on size and weight are established.

You should also consider the following factors when choosing:

• Mounting type;
• Material used as a filler for lamellas;
• The design of the locking device;
• The location of the castles;
• Coloring or pattern on the canvas, etc.

To select the most suitable version of roller shutter systems for installation on window openings in a residential building or office, you need to take into account all the above-mentioned features of the systems. Experienced construction professionals will always help homeowners to choose the most suitable products in accordance with the buyers' ability to pay and functional requirements.

Roller shutter control systems

Mechanical control systems are among the most economical. They are less demanding than automated ones. A properly installed mechanical drive will almost never create difficulties in controlling the web if a short circuit occurs or the electricity in the house goes out.

Several separate varieties of mechanical control systems can be considered:

• Ordinary tape drive;
• Integrated cardan mechanism;
• Special cable reducer;
• Spring-inertial system.

The tape drive is considered the simplest mechanism for opening roller shutters. This mechanism is best suited to aluminum structures. Its maximum weight is about 15 kg. The principle of its operation is as follows: one edge of the tape is fixed on a pulley mounted on a shaft, and the second is placed on a tape paver, which is mounted in the inside of the room. It is enough to pull the tape towards you so that the roller shutters open or close.

The main advantage of such systems is the affordable price. The disadvantages include restrictions on the weight of the installed canvas.

Cardan mechanisms are installed on medium-weight systems weighing up to 36 kg. The mechanism is controlled by means of a cardan handle. The roller shutter can move vertically or horizontally depending on the direction of rotation.

The advantages of the cardan mechanism include affordable cost, reliability, the possibility of installing an additional automatic lock. Disadvantages: the impossibility of output through the wall if the double-glazed window and the box are installed on the same level.

A special cable reducer makes it possible to set the roller shutter curtain in motion by changing the degree of cable tension using a specially equipped handle. The profile can be installed on a cardan shaft with a spring, which contributes to the rotation of the profile web. This is the most convenient way to manage the design. This type of control is considered the most suitable for heavy systems, the mass of which can reach 100 kg.
