Balcony latches - purpose, types, installation, repair

Modern architectural proposals allow the use of loggias and balconies for various purposes.
To arrange the space practically and economically, sliding window structures are used.

High-quality products will not only protect the premises from external factors, but will also create comfortable conditions for its users.

System Description

A sliding system is a window structure consisting of one or more sashes movably mounted on slats. The products consist of the same parts as regular windows - frame, sash, fittings, double-glazed windows.

There are several types of sliding systems:

1. 
   Sliding . The difference between such systems and conventional ones is the opening mechanism. The doors move sideways along special guides, rather than opening horizontally.

   Read also:  Double-glazed windows STiS (stis) with energy-saving glass.
2. Slider . They are also called guillotine or vertical sliding windows. In this design, the movement of the active leaf occurs vertically.
3. Sliding windows .
   The principle of operation of the system resembles the operation of the elements of a wardrobe. A very popular option due to its high-quality sealing. The frame has two rows of guides and several doors that move freely in relation to each other. The third guide is installed for the mosquito net. When the window opens, one sash partially overlaps the second. This type of design is distinguished by the largest size of the valves.

You should also distinguish between the concepts of a window and a window block. The definition is clearly described in STO 89531747-001-2010 “Window blocks. General technical conditions".

In this standard, these terms look like this:

1. A window is a part of a building’s structure designed to communicate the interior with the surrounding space. It can be located in the wall or roof section of the building. The main tasks of a window are to provide natural lighting to the room, ventilation and protection from external influences. Consists of a window opening, a window block, fasteners and an assembly seam. The window may also include ebb, slope lining, window sill, and ventilation valve.
2. Window block . This is the name of a translucent product, the purpose of which is natural lighting, ventilation and protection of the room from noise and atmospheric phenomena. Consists of a frame, sashes, double-glazed windows, hinges, and fittings. The window unit may include blinds and built-in fresh air ventilation devices.

The standard contains definitions of all components of the structure.

Feasibility of installation

This opening system allows you to significantly save space due to the horizontal movement of the doors. This is very convenient for loggias and balconies with small dimensions. They have limitations not only in area, but also in weight load. If the windows are made of light metal, then the weight of the structure allows installation even on the balconies of an old house.

When choosing a material for a window, it is necessary to take into account all the nuances. For example, aluminum is not suitable for northern regions.

Feature of aluminum sliding system

Adjusting aluminum sashes is simple; every home craftsman can do it. The popularity of aluminum frames is growing due to the low price of products and the light weight of frames.

Sliding feature:

• Combining profile guides with a built-in window.
• Special rollers for sliding the web in a given direction.
• Saves space.
• Aluminum ones can be installed without additional strengthening of the balcony base.
• Installation of reinforced shut-off valves.

Such windows are excellent for office buildings, houses where owners want to perform non-standard glazing with very large structures or windows of complex geometric shapes.

Subtypes of designs

Structures are divided into groups based on their differences in the profile material and fittings. To make the right choice, you need to evaluate the degree of functionality of the system and tightness.

Main parameters:

• thermal conductivity coefficient (optimally low value);
• the volume of light received (depending on the width of the profile);
• opening mode.

Main types of systems according to opening mode :

1. Parallel sliding .
   The design has grooves in the lower and upper parts of the sash. They are installed on the frame guides. The product may have several doors. The runners and profile are located on the same level. Therefore, in open mode the sash takes up the same amount of space as in closed mode. This is a big plus, especially for balconies and loggias with limited dimensions. The disadvantage of the system is that it does not allow the installation of multi-chamber double-glazed windows. It is the structure of the sliding mechanism that limits the permissible thickness. Most often, aluminum profiles or budget PVC options are used for such windows.
2. Swivel and slide . The system has more complex fittings. In such windows, the sash can deviate from the profile when opening, which allows you to set the ventilation mode. Guides are installed on the frame and rollers on the sash. There is a standard fittings harness. By turning the handle inward and then to the side, you can open the sash. The advantage of the system is the ability to set the tilt opening mode.

There are also two main types of glazing using sliding systems.

Their difference lies in the level of thermal insulation . Characteristics:

1. Cold .
   Such glazing will provide good protection from precipitation and dust, provide average protection against noise and good protection against burglary. Usually an inexpensive profile is installed, for example, aluminum + single-layer glass. Budget cost is one of the advantages. Light weight is also an advantage. It allows you to install the system on any type of balcony. The downside of the view is the limited time you can use the balcony. It will be very cold to be there in winter and autumn.
2. Warm . There are several advantages. The system provides complete protection of the premises from the influence of environmental factors. The balcony can be used as a living space, especially when installing an energy-saving package. The downside is the cost, which increases due to additional insulation of the ceiling and floor. Usually PVC profiles and lightweight wooden frames are used.

Limitations on the size and formula of the glass unit should be taken into account. It occupies 90% of the weight and 80% of the total area in the system.

There are three options for double-glazed windows that are recommended for sliding systems:

• energy-saving, which are installed with warm glazing;
• safe for the first and last floor of the building;
• simple single-chamber for cold glazing.

You can choose any one depending on the glazing tasks.

Types of window sash clamps

The difference between fixing products mounted on windows is determined by:

• by the type of material taken for the production of the product;
• at the place of installation;
• according to the current mechanism.

According to the material of manufacture

Limiter models are presented in three types:

Plastic products. Combined with PVC profiles. The limiter model can be selected from several colors. With a standard number of locking positions, there are from 3 to 4 positions.

The downside to PVC blockers is their reduced level of strength and rapid wear.

Such types are not recommended for mounting on window sashes located on the side of the house towards which the wind blows. When exposed to squally winds, the plastic may become deformed.

Products made of metal. A durable, reliable option for a window stop. Brass products with anti-corrosion coating exceed other types in popularity. But in terms of color varieties, metal retainers are inferior to plastic ones. Their color range is not so extensive. There is a golden option, a silver tint, a grayish tone, and a copper color.

The main disadvantage of the product is the high price.

Combined fasteners. The metal-plastic model belongs to this type of clamp. The component parts are a comb made of plastic in connection with a metal retainer. If desired, you can choose a strip painted in any color scheme.

In the second option, the strip is attached to the end of the sash. The pin is fixed using long self-tapping screws. This type of fastener is considered more durable.

The valve opening limiter can only be used in PVC profiles. A wooden frame, if such a limiter is installed on it, will become deformed.

By mounting method

There are two different installation methods:

1. Installation under the window handle. The comb is fixed to a stationary part of the frame. She moves comfortably. The limiter is prevented from catching on hanging curtains. Excess internal volume is not captured.
2. Installation of the comb at the end of the sash. Long self-tapping screws will come in handy to secure the pin. They are rigidly attached to the lintels of the sash overlay. Fastening the clamp into the weld can only be done in plastic profiles. Wooden frames may become deformed. Natural wood fibers are not able to withstand the forces from the pin.

By mechanism of action

Installation of an opening limiter on plastic windows classifies it into groups representing:

1. External comb. A simple device for the folding version of the sashes. The window is fixed for ventilation. The level of child protection is low. The child can handle the limiter quite well. Children must be supervised.
2. Built-in limiter. Same as the outer comb in terms of functionality. The advantages are the aesthetics of the view, secretive placement. Disadvantage: security is not provided.

Flaws:

• high price;
• the risk that the device will break if the window is opened suddenly.

Constant action brake. Performs blocking of the sashes. Thanks to the operation of the mechanism, their spontaneous opening is eliminated.

Requirements for the coupe

The necessary issues are covered and systematized in the text of GOST R 56926-2016:

1. 
   The translucent filling must transmit the visible spectrum of solar radiation in the range of 770-380 nm, ultraviolet - 200-380 nm.

2. It is allowed to use glass with a self-cleaning coating.
3. The light transmittance value is 0.7.
4. The design must have limiters to prevent the sash from falling out of the window.
5. The maximum sash size is 800 mm x 1800 mm, area no more than 1.5 square meters. m.
6. For a French balcony, additional fencing is required, taking into account the requirements of GOST 23166.

Glazing must provide the possibility of emergency exit, environmental friendliness of components, compliance with fire safety standards and be resistant to natural factors.

Which window is considered burglary resistant?

To break into a standard Euro window, a burglar does not need tools, experience or outstanding muscles. Anyone can press their shoulder on the sash and squeeze it out in 10-15 seconds. It is clear that when it comes to safety, carelessness is not an option, and homeowners have always thought about how to strengthen their windows. Many can remember a time when bars were installed everywhere on windows, but time has shown that this was a bad decision.

Alexey Mosko Internet promotion and public relations specialist at Roto Frank

Grills are not the best solution for window security. They do not look very aesthetically pleasing, spoil the view from the window, and create the feeling of a fortress or even a prison. And most importantly, they make it difficult to evacuate in case of fire.

Webmac FORUMHOUSE Member

I have a prejudice towards bars: they seem to be free, but the sky is checkered or striped. It's annoying!

A modern burglary-resistant window does not require a grille. However, it is difficult to open even for an experienced burglar.

Alexey Mosko

The most secure window is invulnerable to impact and power tools: sledgehammers, saws, axes, drills and grinders. But this will require strengthening of all window components: the profile system, double-glazed windows and fittings.

Only a window with comprehensive preparation of the entire structure can be considered burglar-resistant. It must be equipped with triplex, glued double-glazed windows, closed reinforcement and anti-burglary fittings. This design also requires special installation.

An integrated approach to window security is reliable, but expensive.

BIG-HORROR FORUMHOUSE Member

Anti-burglary fittings, coupled with triplex, and multiplied by all the windows - the cost is inhumane, the amphibian will begin to spawn out of season.

But such maximum window reinforcement is not always necessary. Each situation must be considered individually. Often it will be enough to install anti-burglary fittings.

Tools and accessories for installation

High-quality installation will provide a set of necessary tools and devices. Before starting work you need to prepare :

1. Stretcher. This is a metal profile for a balcony or a wooden board for a loggia.
2. Drill or screwdriver.
3. Dowels, thick and long screws.
4. Roulette, triangle.
5. Construction level, plumb.
6. Marker, pencil.
7. Polyurethane foam, gun, sealant.

Fastening elements can be different - dowels, anchor bolts or plates.

Types of latches for a balcony door

As a rule, the latch for a pvc balcony door is made of metal and plastic. Although there are plenty of modifications to the locking elements on the door, nevertheless, balcony latches for plastic doors can only be divided into two types: magnetic and mechanical.

Both have a fairly simple locking mechanism and a simple design. This allows you to install the latch on a plastic balcony door without any special tools or professional skills.

If problems arise during the operation of the locking mechanisms, in most cases they can also be corrected independently. As for choosing the best option for a door lock, it depends solely on the individual preferences of the owner.

Installation features

Of course, there is a general algorithm for the process of installing sliding-type structures. However, each type of room requires installation nuances.

Balcony

When glazing you can use useful recommendations:

1. 
   On a large balcony (no more than 6 m), it is better to make a sliding system with a frame. In this case, when you move the doors apart, there will be a completely open opening in the center with an excellent panoramic view.

2. Next to the sliding sash you need to install one hinged sash, not a blind one. This will allow you to conveniently care for the structure. An important nuance is to use a removable handle with a plug so that it does not interfere with the movement of the sash.
3. On the sunny side of the building, solar control or multifunctional glass should be used.
4. When glazing a balcony on the top or ground floor, it is necessary to install anti-burglary fittings and tempered glass.

also need to fulfill the requirements and restrictions :

• glazing should not change the appearance of a multi-story building;
• Replacing frameless glazing installed by the developer with warm glazing can only be done after changes to the project.

All actions must be agreed upon with the developer.

Loggia

For warm glazing of loggias, frames with a wall thickness of 3 mm are used . The base for mounting the profile is made from a 30-40 mm board.

To temporarily fix the frame, according to the instructions, you must use perforated tape. Plastic adjustment pads are needed to adjust the horizontal.

Sliding balcony block

The balcony block is a heavy and large structure. Installation should only be performed with an assistant. If the block has a blind window, then before installation it is necessary to remove the double-glazed window. Remove the door from its hinges.

It is important to position the block correctly so that there are no distortions. Otherwise, the parts will rub together. You should also install a wide window sill so that it extends 2-3 cm under the frame.

How to install a limiter yourself?

The limiter can be mounted even on windows that have been installed for a long time. This is provided for by the design of the part.

Required materials and tools

To properly install window protection, you need the following set of materials and tools:

• comb (window stop) with a pin;
• a pencil or other tool for marking a plastic surface without damaging it;
• electric drill with a drill of suitable diameter;
• a screwdriver or mechanical screwdriver with a cross-head bit;
• metal screws up to 1.3 cm long.

The length of the screws is indicated as a maximum in order to keep the window profile intact.

Installing the fastener yourself

Installing the clamps will require several steps:

1. Release the sash from the handle.
2. Install the lock in place under the handle.
3. Put the handle back on, but now on the installed clamp, and then fasten it with screws.
4. The position of the bar should be marked with a pencil or self-tapping screw.
5. At the marked point, it is necessary to make a recess strictly perpendicular to the plane of the frame for the length of the self-tapping screw.
6. The design of the limiter is fixed with self-tapping screws.

Advice! Since the comb cannot be reinstalled, it will need to be installed correctly the first time.

If installed correctly, such a system will operate for a long period.

Attaching the comb strip to the frame

To prevent the double-glazed window from depressurizing and causing other damage critical to the structure, all actions must be performed very carefully. It is necessary to comply with the requirements for the length of the screws, the location of the strip and the lock, so that this does not interfere with the closing of the window sash.

The location of the latch must correspond to the location of the comb itself (located opposite it). Before final fixation, the functionality of the mechanism and the free movement of all elements of the window system are tested. Actions are performed according to the following algorithm:

1. When the latch is installed at the previous stage, the window is covered, and the required level is marked on it for the location of the bar.
2. A mark is made with a pencil.
3. The window is fixed in a stationary position by holding the guide with your hands.
4. The strip is screwed to the frame with self-tapping screws after checking the functioning of the window and mechanism.

Using an adhesive will not be effective, since regular loads will quickly destroy the adhesion of the plank to the frame.

What accessories will be needed?

This system uses parallel-sliding fittings. Parts can be divided into external and internal. External devices include handles and hinges.

Good options for the system are a handle with a lock and an anti-theft handle . It will reliably protect the balcony from burglary, and children from accidentally falling out. The hinges can be installed hidden. It is also necessary to pay attention to the quality of the seal.

Setup and adjustment

A typical failure of the fittings is the difficulty of moving the balcony frame and the failure of the latch to operate. In the first case, the cause is the incorrect position of the rollers. To make adjustments, you should visually inspect the structure.

There are holes at the ends, inside of which there is a 4 mm hexagon screw.
Roller settings :

1. Frames. To raise the frame, you need to turn the screw counterclockwise with a wrench. Use a level to check that there is no diagonal distortion. The latch should close easily.
2. Doors. You will need a key number 2.5 to adjust the counter part. The part must be screwed to the same level at the top and bottom.

If the latch does not work , then the reason is the location of the strike plate and the lock tongue at different levels. As a result, there is no clutch or the tongue has sunk into the frame. Solution to the problem:

1. No hitch. It is necessary to move the parts to the same level. This is done with a 2.5 mm hex key. The movement of the bar should be freed. On the part located on the left, the key must be turned to the right. On the one on the right, turn left. After releasing the strip, you will need to mount the part until the top of the tongue coincides with the bottom of the part. Then screw the bar.
2. The tongue has sunk. You need to pull the handle down and turn the locking screw in the opposite direction. The 3 mm hexagon should be rotated to the right for the left location, and to the left for the right location. Loosen the screw, take out the tongue, and pull it out to the desired level. Tighten the lock and check that the latch operates.

Before starting work, you should read the instructions for the window.

How to adjust the rollers?

Plastic is heavier than aluminum. Find an assistant to support the structure.

1. Find the location of the adjustment screws. They are located at the bottom at both ends. 4 mm hexagon.
2. Remove the cover and find the hole. Insert the screwdriver and twist to the left.
3. Height adjustment is performed on both sides. To do this, using the selection method, they rotate the screws, moving the roller mechanisms until they achieve normal movement of the sash. An assistant must check the position of the frame by level. Do not allow skew diagonally.
4. Fix the optimal position.

Be sure to maintain systems. Lubricate locks and fittings seasonally with silicone grease. When washing glass, wash all parts. Dust and dirt get clogged and create problems when moving. If it stops opening in winter, it may have frozen over. If it is not critical to use, wait until it thaws. If you urgently need to ventilate, use an industrial hair dryer to defrost and heat.

Window structures with a sliding system are considered durable. The manufacturer issues a warranty for the profile for up to 10 years, and for fittings for up to 5 years. When choosing, pay attention to installation. Functionality and service life depend on correct installation. Windows open several times a day. The load on the parts is high. Saving on the quality of seemingly minor elements will cost you more during repairs and replacements. We hope the tips are useful to you. Not confident in your abilities? Do you have any doubts? Don't take risks, call a contractor.

How and with what can you insulate?

Additional insulation is recommended when cold air penetrates into the room or the system freezes.

In sliding structures, it is possible to insulate not only the frame contour, but also the line where the profile joins the ebbs, slopes and window sill:

Insulation methods may vary depending on the frame material:

1. 
   Wooden structures can be insulated with sealant and sealant. You need to cut a groove around the perimeter of the sash and put a seal in it. Use sealant at the junction of glass and wooden frame.

2. Aluminum windows are insulated with polyamide inserts - thermal break.
3. For PVC profiles, it is recommended to insulate the slopes, adjust the fittings and replace the seal.

Kinds

The limiting elements may differ in the number of grooves. Standard models have 4 slots, but there are also options with 5 slots. In addition, there are several types of combs.

Outdoor

Designed for folding window sashes (for example, vents). It has 3-4 grooves, fixes the sash while ventilating the room.

Built-in

Invisible to the eye analogue of the external comb. In terms of its functioning and number of grooves, this option is identical to the one described above. The difference is the greater aesthetics of the window, since the built-in limiter is invisible.

Cable limiter

Structurally, it consists of 2 elements, one of which is fixed on the frame, and the second on the profile. They are connected to each other by a metal-based cable (sometimes in a plastic braid). There are models where the cable is replaced with a thin chain. The micro-ventilation function is realized thanks to the short (up to 20 cm) length of the cable.

Unlike a standard comb, it does not allow you to fix the sash, but only holds it, preventing further swinging of the window. At the same time, the cable stop is stronger than the comb and can withstand a breaking force of up to 550 kg (depending on the model).

For protection against children and unauthorized entry from the outside, a cable stopper is more suitable than a comb. For ventilation it is better to choose the latter.

When installed on swing sashes, the limiter can be mounted anywhere in the profile and frame; when mounted on tilt-and-turn structures, only in the upper part.

Constant brake

Perhaps such a name will seem unknown to many, although, perhaps, everyone has come across such mechanisms for sashes. A permanent brake is usually installed on the doors of shops and offices. All a person needs to do is pull the door towards him and open it. No need to close. Thanks to the built-in mechanism, the door will slam shut automatically.

A similar system is mounted on a window, preventing the sash from spontaneously closing or swinging open excessively. Such a mechanism should not be pulled by force when trying to cover the window, as it may break.

Handle-lock

This is the most effective limiter that provides protection against children opening the window. It is a metal handle with shut-off valves. There is a lock on its outer part. Opening is done with a key.

What difficulties might you encounter?

This type of glazing has several typical problems that usually appear when the ambient temperature changes sharply. These include :

• quick change of geometry under its own weight;
• sagging of the sash, which leads to drafts;
• handles breaking due to frequent use.

You should not wait for a problem to appear and take preventive measures.

Troubleshooting solutions

To prevent changes in window geometry, adjustments must be made at least once a year . When the problem appears, it can also be eliminated by adjustment.

Sagging of the sash requires moving the panel and tightening the fixing screws. Breakage of the handle can occur due to the expiration date or frequent opening of the window. In this case, it is necessary to replace this part of the fittings.

Locks for windows and doors are a useful little thing that saves money

Ventilation of rooms, especially in which a person spends a long time, significantly improves well-being. Therefore, it is important that proper air exchange is carried out on a regular basis, and as often as possible. Thanks to universal latches for windows and doors, the user does not have to worry that any gust of wind may be accompanied by a noisy, unpleasant sound of slamming doors or windows, or, in the worst case, the roar of broken glass. Universal fasteners are a solution for those who want to forever forget about windows and doors slamming under the influence of a draft, which can be associated with losses.

Dismantling of structures

There may be several reasons for removing the sliding system:

1. For washing glass from the street side. This will allow for quality cleaning.
2. During a major renovation of a balcony or apartment. Removing the sashes will protect the fittings and glass from damage and construction debris.
3. If you need to replace the glass unit. This occurs when a part is damaged or replaced with a new version.
4. When replacing accessories. It is much easier to install new elements if the folds are removed.
5. Complete dismantling of the balcony frame is required. Most often this happens when a product is replaced.
6. When replacing cold glazing with warm glazing.

In any case, the first step will be to remove the sashes.

Tools for work

To work you need to prepare a set of tools :

• scrap;
• hammer;
• saw;
• putty knife;
• saw;
• screwdrivers of different types;
• sandpaper.

In addition to the listed tools, you will need to prepare a protective film for glass.

How to remove correctly - step by step process

Before starting dismantling work, you will need to perform a number of preparatory actions :

• clean the balcony space;
• prepare a place for the removed parts in the next room;
• cover the glass with protective film;
• invite a partner.

Dismantling process:

1. Slightly lift the movable sash with both hands until the lower part comes out of the guides. If the sash does not rise, there are three solutions. If there are notches on the guides, you need to bring the edge of the sash to them and remove them. If there are grooves, then they need to be aligned and the sash lifted. If there are blocking plugs, they need to be removed by picking them up with a screwdriver.
2. Remove the glazing beads, remove the double-glazed windows, and remove the glass from the blind sections.
3. Remove the frame and clear the opening of debris.

Now you can begin further work.

Locks for windows and doors are a useful little thing that attracts big money

A universal fastener for windows and doors can become a business card of a company, allowing its logo to be applied to the surface of the product. This will be an additional marketing ploy in our very competitive market. After removing the protective film from the profile, the window becomes somewhat faceless, because the manufacturer’s branding is removed along with it. If you install a stopper with the logo of a window company next to such a window, then anyone who comes to visit the owner of the house will remember in his memory who is the “author” of the system he likes.

Pros and cons of such glazing

Any design has its own advantages and disadvantages.

of a sliding door are :

• maintaining the volume of the room due to the method of moving the sashes;
• reliability, withstand heavy loads;
• uniform load distribution when open;
• the ability to install a frame from any material;
• possibility of installing radius structures;
• elegance and modern look.

Flaws:

• price;
• labor-intensive care from the outside;
• the need to divide the structure into blocks.

The advantages of the system outweigh the disadvantages.

Consumer Reviews

Users post their reviews on forums. Among them are positive statements :

• practicality, space saving;
• beautiful appearance;
• ideal for warm regions.

Flaws:

• difficulties with purchasing a mosquito net;
• low noise insulation;
• poor heat savings.

It should be noted that user opinions may vary depending on the frame material.

All the colors of the rainbow for the aesthetics of windows and doors

Universal clamps for windows and doors are offered in up to ten different colors, and there is also the possibility of selecting an individual color scheme. Therefore, the user can really choose a stopper that best suits the tastes of the inhabitants of the house. Moreover, the wide range of colors of the clamps also allows you to harmoniously fit them into the interior in accordance with the tone of window frames, walls, furniture or curtains. Today you can choose purple, orange, yellow, white, red, black, blue, pink, mint green stopper colors, as well as a transparent option.

It is worth noting that the universal lock for windows and doors, which in its most common version resembles the shape of a teardrop, can become not only an important tool in the fight against drafts, but also pleases the eye, being an original decoration. Creative thought does not stand still and more and more intricate stoppers are appearing on the market that can delight, surprise and even amuse.

Average prices in the Russian Federation

Below is the cost for different types of structures :

1. Budget option - cold glazing of the loggia with aluminum structures - 3300 rubles per 1 sq. m.
2. Warm premium aluminum - 5100 rubles per 1 sq. m.
3. Cold glazing of a balcony - from 4000 rubles per 1 sq. m.
4. Warm glazing of a balcony - from 4,700 rubles per 1 sq. m.
5. Single glass design - from 1,400 rubles per 1 sq. m.
6. With double-glazed windows - from 1,750 rubles per 1 sq. m.

Features of the latch on the balcony

The latch is equipped with fittings to lock the door when a person is on the balcony. This is suitable for smokers who do not want smoke entering the living area. In addition to this there is dust, street noise, bad weather and cold air. The fittings help get rid of troubles if the door is accidentally slammed by a gust of wind and no one is home.

This door assembly consists of a frame part and a pin. And if the first element depends on the type of frame profile, then the sash part is universal. The balcony latch depends on the type of frame profile, but the trunnion element is a universal one.

The part is attached to the leaf of the sash and, using screws, is securely held by the door in the required position. The operation of the product is ensured by a latching system, which is activated using a handle (spatula, false handle or smoker handle). Small dimensions make the fittings almost invisible, so they do not spoil the interior of the apartment.

Tilt-and-turn mechanism for plastic windows

The tilt-and-turn mechanism for plastic windows is an optimal and reliable solution. Combines the advantages of tilting and rotating systems. Allows you to fully open the sash and set it to ventilation mode.

Modern tilt-and-turn fittings make it possible to adjust the degree of opening and the pressing force of the sash when closing. To open the window, you need to move the handle to the horizontal position. To activate the ventilation or micro-ventilation mode, you need to turn it up vertically or install it at an angle of 10-35 degrees. To perform such operations you only need one handle. Its design is complex. Window units with this locking method are more expensive.

How to choose a set of accessories

When choosing window fittings, you should always look at it from the point of view of your own safety. Will you have peace of mind for your family in a house with such windows? Can you go on vacation with a light heart? Standard hardware kits most often do not have burglary protection. However, trusted manufacturers equip even basic versions with a burglar-resistant mushroom-shaped pin. It is located in the corner of the sash.

To enhance the protective characteristics of the fittings, counter-movement locks are installed on the sides of the sash. In this version, two mushroom-shaped pins simultaneously extend from both sides of the anti-burglar strike plate. It will be much more difficult to bend a sash with such protection from the side than a regular one. Such a window will correspond to the WK 2 burglary resistance class: it can withstand a screwdriver, pliers and wedges.

In class WK2 systems, trunnions are additionally installed on the corner switch and on the scissors. The distance between the main locking points decreases, and such a window is already resistant to crowbars and crowbars.

You can enhance the security of panoramic, balcony and terrace doors with a hook lock.

The principle of operation is similar to door devices: additional fixation comes from a special steel hook, which is firmly attached to the counterpart on the frame.

Alexey Mosko

If you really value your home, then you shouldn’t skimp on a reinforced burglar-proof window kit, especially if you are furnishing a country house. The protection system will add approximately 5 thousand rubles to the cost of the window. But it is a sound investment in the health and safety of your family. It's a matter of priorities. Those who care about comfort of use, design, and safety choose professionally developed solutions.

A tilt-and-turn window with anti-burglary fittings is no less functional than a regular window. It opens softly and smoothly in both horizontal and vertical planes.
