You should worry about the quality of the devices that open and close the doors and ensure tightness in advance. We have collected information about popular manufacturers and compiled a rating of the best of the best. They also told us what types of fittings are available and what to look for when choosing them.

How window fittings work

The standard set consists of 3 nodes:

• loop group;
• locking structure;
• mechanism for turning the sash.

It is also distinguished by the method of opening:

• Swivel - equipped with a vertical suspension, opens the window.
• Folding - changes the position of the sash up or down.
• Tilt and turn - the position of the sash is adjusted by turning the handle: in one mode it opens in the usual way, in another it tilts.
• Middle-hung with horizontal suspension - allows you to open the sash 180°. This model is needed for openings of non-standard configuration (oval, round).
• The transom is a more complex mechanism than the previous ones. There are 3 opening methods: using a central locking lock and an internal opening limiter, a lever system, and installing an electric drive for remote control.

Note: turning fittings are good for balcony doors, tilting fittings are good for attic window openings, and tilting and turning fittings are good for rooms.

Components

The equipment of PVC windows consists of many parts combined into complex mechanisms. Let's look at its main types.

Turn limiter

Needed to fix the sash in the extreme open position.

Latch

Prevents the window from swinging open in the wind or strong draft. Latches can be mortise, overhead, mechanical, magnetic corner, or roller.

They are placed on visible parts of the fittings for decoration.

Element for lifting a sagging sash

Reduces the load when open and removes pressure from window hinges when closed.

Folding scissors

They help install the tilt-and-turn sashes in the position specified by the position of the window handle. The mechanism increases comfort, but you cannot turn the handles when the sash is open: this is a serious test for the mechanism.

Children's castle

Prevents preschoolers from accessing the window opening. It is placed inside the window handle or attached to the sash or frame.

Turn blocker

Prevents the window from opening more than necessary. The functions are similar to those performed by a child lock.

Multi-point lock

Usually consists of several constipations. Both the crossbar type and the latch type are used.

Traditional latches, pins, and hooks also belong to locking hardware.

Pen

The standard set includes a screw with fastening, an overlay and the handle itself. The materials are plastic, metal, wood. In addition to stationary ones, manufacturers produce removable handles. Some are equipped with a lock. There are anti-burglary handles that have a built-in mechanism that blocks the window if you try to get inside from the street.

They conserve heat and provide the sash with reliable contact with the window profile. They resist deformation well, are elastic, and come in different colors and cross-sections. Made from modified plastic, rubber, rubber.

Brush seals, which combine a polypropylene-coated woven base with silicone-treated bristles, are popular in sliding windows.

Loops

They have several variations:

• Overheads can be detachable or one-piece, as well as rotary or tilt-and-turn.
• There are anti-burglary ones with special plates that cannot be disassembled when the sash is closed.
• There are screw-in hinges on threaded pins.
• Inconspicuous loop designs are appreciated by lovers of stylish interiors. Elements of such hinges are not visible from the front side of the window. Invisible hinges seriously improve thermal protection.

Trunnions and strips

They are small constipations and serve as part of the locking mechanism. Their task is to engage the parts when turning the handle, ensuring normal contact between the sash and the window frame.

Angle switch

Participates in locking the window sash from the corners, moving it to the tilt-and-turn position. The material is particularly strong steel. Anti-vandal corner switches reliably protect against burglary.

Constipation

Their task is to open, close, and fold back the doors. There are basic, intermediate and additional.

Rollers

Needed for smooth movement of sliding window sashes, they consist of wheels with fastenings. They are made of nylon, metal, plastic, but rubber ones are more convenient and do not make noise.

Stops

Installed on the window sill or handle so as not to damage the sash when opening. There are metal with rubber lining, plastic, equipped with a magnet, permanent and temporary.

Ventilation valves

These are ventilators that remove stale air. The inlet valve prevents the formation of condensation.

Note: the cost of reliable equipment reaches 15% of the price of a window unit.

How not to make a mistake in choosing

Fittings of mediocre quality will not last long, because PVC windows are used intensively and are opened and closed many times every day. What you need to do to avoid regretting your purchase later:

• Decide for yourself which method of opening the doors in a particular case will be optimal.
• Measure the parameters of the window and choose a set of fittings that corresponds to the obtained dimensions.
• Buy products with the brand of a company with a good reputation.
• Choose components made from quality materials. Do not be seduced by cheap plastic parts: their service life is short. It's better to stick with metal kits.
• Make sure that there are no burrs on the parts; the metal parts must be perfectly smooth and even.
• Make sure that the parts have at least 2 holes for fastening.

Note: a large variety of decorative overlays with a limited choice of fittings itself should alert you: there is a high probability that the product has flaws that need to be disguised.

The best fittings for plastic windows: manufacturer ratings

Sophisticated buyers choose products from manufacturers with a good reputation. Although their product is more expensive, in the future it will cost much less than expensive repairs. The well-known phrase about the miser who pays twice is still relevant today.

Note: you can find the brand name by slightly opening the window sash: usually the markings are applied to the steel parts of the equipment.

Roto

The German brand Roto produces a wide range of reliable fittings. There is the possibility of not only complete, but also partial configuration: someone needs an alarm or anti-burglary devices, while others are interested in child safety units.

HELPFUL INFORMATION: What is a stand profile and why is it needed: dimensions, insulation and installation

Advantages of Roto products:

• 10-year warranty service;
• reinforced anti-corrosion coating;
• The reversal unit deserves attention, helping to wash windows without any problems.

Disadvantage: some models are designed only for windows weighing no more than 80 kg.

Reviews

Denis K.: “Indeed, the quality is real - German. Disadvantages - this is not about Roto. I have comparison experience. 5 years ago we were seduced by the low price, a year later everything had to be changed, the purchase turned out to be from China. After its replacement, the Roto equipment has been in service at the dacha for 4 years, and the same was installed in the apartment.”

Sweet22: “All windows have Rotov products installed. Of course, it is more expensive, but it works great: not harsh and not too soft. It’s been working in the kitchen for three years without any notice, in the bedroom for five years.”

Maco

The fittings of this Austrian manufacturer are in constant demand for the following reasons:

• elegant look;
• 6 levels of burglary protection;
• variability of window frame positions when moving;
• protection of windows from accidental damage due to careless handling;
• 10 years warranty;
• smooth operation of all mechanisms;
• mandatory presence of a microlift;
• The wax included in the outer coating reliably protects against corrosion processes.

Vadim Vladimirovich: "Miser pays twice. To prevent this from happening, I recommend the Maco brand.”

The brand is known for high-quality products that are used for windows in luxury housing. The respectable company Veka, one of the recognized manufacturers of PVC windows, equips them with fittings from this particular company. Each of its elements is produced in Germany.

Main advantages:

• the ability to change the height of the sash position and rotate it in any direction;
• 7, not 5, as usual, pressure points make the window completely sealed;
• the maximum load reaches 1.5 tons - this is an eloquent confirmation of the highest defensive ability against the actions of intruders;
• compatible with windows of non-standard configuration.

• high price;
• the need for service every six months.

Do you have to choose window fittings? Then this material is just for you! In it, our experts share information that will open up many interesting devices for you and tell you about the features of each type. This article will help you understand the fittings and select those elements that will minimize heat loss from the room and ensure its safety.

What is window fittings called?

Window fittings are a device that combines various mechanisms designed for the full functioning of the window. Handles and hinges, locks and seals are those elements whose importance is difficult to overestimate, although we do not give them due importance. But even a small malfunction in the window mechanism on a frosty winter day, for example, can lead to not very pleasant consequences. Therefore, all components of PVC windows must be of ideal quality, assembly and stable strength.

Plastic window fittings diagram

Window fittings are:

1. Loops. Or the so-called loop group, which consists of lower and upper loops.
2. Mechanical locking window elements.
3. Rotating components.

When choosing accessories, the most important thing is to pay attention to its quality, because its service life will depend on this.

Classification of fittings according to the method of opening the window

Three groups of mid-hanging fittings should be distinguished:

• having a locking central lock and an internal tilt limiter;
• opening 90° due to the lever system;
• controlled remotely by means of a remote drive;
• tilt and turn. Allows you to use a knob to select the location of the window;
• components for PVC sliding windows.

PVC windows have the largest variety of fittings. And, in order not to make a bad choice, later in the article we will look at its specifics and tell you how to determine a quality product.

Main types of accessories

Fittings include not only mechanisms, handles and hinges. The range is quite wide:

They are divided into several types based on materials of manufacture:

1. Brush. Their special feature is silicone “lint”, which creates good sound insulation and excellent temperature retention.
2. Rubber. Elastic and durable, they have different cross-sectional shapes and are made in a variety of different colors.
3. Silicone. They have excellent temperature resistance.
4. Thermoplastic elastomers.
5. Ethylenepropinelic. Like silicone, they are well resistant to temperature fluctuations and ultraviolet radiation.
6. Chloroprene.
7. PVC seals.

1. Window hinges.

Can be:

1. Standard invoices.

1. Screw-in loops. Installed with threaded pins or mounted into a profile. Hinges of this hidden type have a long service life and are capable of opening the window sash by 100°.

1. Window locks:

1. Stops. Protection, which is presented in the form of linings on a temporary or permanent basis, is located on handles, on the floor or any other surface, and protects windows from damage. One of the most useful secondary things actually.

1. Mosquito net. The design is designed identically to window frames and is installed using hooks or adhesive tape. Also, nets can be sliding or roll type.

What are sliding windows?

All sliding windows, or rather, their assembly mechanisms are divided into several types.

The most common of them remain three types:

1. Parallel sliding. Everything we need for convenience and aesthetics. Fittings of this type have proven themselves well in Russia. Easy to operate, can be installed on structures of different sizes, excellent design style. All this makes parallel-sliding fittings very popular.
2. Folding parallel-sliding. Allows you to open both doors at once using just one handle.
3. Lift-and-slide. It is considered the most reliable, capable of supporting the weight of the sash up to 400 kg.

The best manufacturers

Pay attention to the progressive leaders in the global market for the production of window fittings:

Selection of accessories

In order not to make a mistake when choosing accessories for your home, you should contact only trusted manufacturers. After all, basically, the overall reliability and durability of window structures depends only on the quality of the fittings you choose.

That's why, When choosing accessories, you need to focus on such product qualities as:

1. Ease of use, minimal maintenance requirements.
2. Long term.
3. Adaptation of the manufacturer to customer requirements.

It should be remembered that the price of good fittings is only 15% of the total cost of the structure, but you should not save on it. It is better to buy it once and for a long time than to fix minor problems caused by the same insignificant external factors a hundred times.

Conclusion

Choosing really high-quality fittings is not so easy, because the quality depends on many factors. But when buying from a reliable manufacturer, you can count on the cost: the more expensive it is, the better quality it will be.

PVC plastic windows are an expensive product, so the consumer wants them to last a long time and not have any problems during their operation. This can be achieved by choosing the right window components, on which its performance and reliability directly depend. Let's figure out how to choose fittings for PVC windows.

Types

Window fittings are a collective name that includes a whole class of mechanisms that provide opening/closing of the window, the degree of pressure of the sash to the profile, its position in space, etc. Low-quality components quickly fail, so saving on them is not advisable. Cheap counterfeit products from well-known brands are one of the most common window problems.

The fittings are assembled according to a modular principle. The kit includes the required elements:

• Loop groups.
• Constipation.
• Sash rotation elements.

If necessary, the kit can be expanded by installing additional parts that provide protection against burglary or against children, ease of opening/closing, etc. It is better to choose steel products that are characterized by maximum strength and reliability.

There are several types of fittings based on the method of opening the doors:

• Rotary mechanisms with vertical suspension. They are most widespread as the simplest and most affordable option.
• Rotating mid-hanging fittings. It differs from the previous type in the presence of a horizontal suspension, which allows the sash to rotate 180 degrees without the risk of sagging. The advantages of these mechanisms include good protective functions and the ability to be installed on windows of any configuration, including round and elliptical.
• Tilt-and-turn. Another popular type on the Russian market. Depending on the position of the handle, the sash swings open or tilts back for ventilation.
• Sliding mechanisms. Not often used on windows. Sliding systems have found their application in balcony glazing.

A separate group includes locking mechanisms for transoms. It is easiest to select components by type. It all depends on the desired method of opening the doors.

Additional items

The main elements are responsible for opening/closing the doors and their correct position. The installation of additional elements allows you to expand the functionality and facilitate operation. Despite the fact that it is not necessary to install them, it is more advisable to opt for expanding the standard set, especially if it is important to provide additional protection against burglary or the safety of small children. Additional components include:

• Turn limiters. Their purpose is to fix the open sash in the extreme position. By installing a brake along with a limiter, you can ensure the stability of the structure when opening up to 150 degrees.
• Turn blocker prevents the window from opening spontaneously and limits the angle of rotation. It is recommended to install in apartments where there are small children, as well as in houses located in areas with frequent strong winds.
• Plastic covers- one of the elements on which you can safely save. Their purpose is to cover the visible parts of the mechanisms, giving the window an individual design. In sets offered by reliable manufacturers, the number of caps corresponds to the number of mechanisms included in the set. If the choice of decorative elements is too wide, you should think about the quality of the fittings.
• Children's castle. This part is not included in the standard set. It is worth buying it if there are small children in the house. By accidentally opening a window, a child may fall out of it. The lock securely fixes the door; it is impossible to open it without a key. Manufacturers offer different lock options. The simplest one is included in the design of the handle. More complex functional mechanisms are mounted on the sash.
• Microlift. The part does not affect the functionality of the window, but it reduces the load on other mechanisms, thereby extending their service life.

Recently, automatic fittings, the operation of which is controlled by an electric drive, have become popular. Automatic mechanisms can be programmed to ventilate. In case of unauthorized opening, a signal will be given.

Manufacturers

The domestic market offers products from different manufacturers. The ranking of the best companies includes:

• Maco. The Austrian brand "Mako" is very popular. The product range includes rotary, tilt-and-turn, and anti-burglary fittings. All mechanisms are hidden mounted. Maco is the best choice in terms of price-quality ratio.
• Winkhaus. One of the oldest manufacturers of accessories for plastic windows. Offers reliable mechanisms, characterized by simplicity and ease of adjustment using special lifting rollers.
• Roto. The products of the German company are known under this brand. It is distinguished by durability, reliability, and quality. The manufacturer provides a 10-year warranty on all mechanisms. Roto fittings can be distinguished from fakes by their flat locking tongue.
• Siegenia-Aubi. Another German brand whose range includes kits for aluminum, plastic, and wooden frames. A distinctive feature of the components is the ease of adjusting the sash in all positions.
• G-U. The company produces all types of fittings, many additional mechanisms, anti-burglary lines. The products are reliable, durable, and easy to adjust.

The rating of manufacturers can be expanded, but the products of these companies are in greatest demand in Russia due to their quality and reliability. Choosing fittings for PVC plastic windows from any of these manufacturers will ensure the durability and ease of operation of the window. When choosing components, you cannot save money. The best fittings for plastic windows are high-quality and reliable mechanisms that can withstand numerous opening/closing cycles.

Modern window fittings for plastic windows are complex mechanisms that combine many items.

It ensures that the window opens/closes and is pressed tightly against the frame. Naturally, all components for PVC plastic windows must be of high quality, because we open and close the window several times every day.

What is window fittings

All components are created according to a modular principle. A standard set is provided here, consisting of the following elements:

Loop group (top and bottom);

Mechanical locking elements;

Accessories for turning a window through a corner.

The functioning of fittings for plastic windows and doors is to transmit traction to the pressing and locking elements through the handle. Therefore, it is very important to choose high-quality material for components.

Important: Metal components for installing PVC windows must be made of high quality steel. They are characterized by durability and practicality.

How are fittings classified by opening method?

The main classification of window fittings for plastic windows involves its division according to the method of opening the window:

Rotating, with vertical suspension - the most common type;

Mid-suspended, horizontal suspension

— thanks to it, the window sash can rotate 180° and fix any position for as long as desired without the threat of sagging. Allows you to adjust the sash and additionally protects against burglary. It can also be used in non-standard shaped structures, including elliptical ones. The fanlight system is considered a complex mechanism and is also classified into 3 groups according to the opening method: with a locking central lock and an internal tilt limiter; with a lever system that ensures the window sash opens 90°; with electric drive and remote control;

Tilt-and-turn. With its help, the location of the window changes depending on the handle. These components are also used for ventilation systems;

Accessories for PVC sliding windows.

But the most important thing is that there are a huge number of types of window fittings for PVC windows, which one way or another you will have to understand if you want to install a truly high-quality window.

Main types of accessories

So, what types of fittings for plastic windows exist, photos and descriptions:

1.Turn limiter. Needed to fix the window in the open extreme position. Can be installed with an additional brake.

2. Latch - will not allow the sash to swing open if there is too much draft or wind. They can be mortise or overhead, mechanical and magnetic (they are more reliable in fixation), angular or spring-loaded roller. Read in a separate article about latches on the balcony door, which are similar to window structures.

3.Decorative overlays are placed on visible fittings and create a unique designer look for the window. If the manufacturer offers a lot of overlays, and the range of accessories is not large, it means that the products are of low quality and have flaws that need to be hidden.

4.Element for lifting a sagging sash. Allows you to reduce the overall load from the heavy sash, regardless of the open position, and relieves pressure from the hinges when the closed position.

5.Folding scissors are necessary for comfortable use of the structure. Helps install tilt-and-turn windows in the open position corresponding to the window handle. If your window has scissors installed, then you cannot change the position of the handle when the sash is open/ajar, otherwise all the fittings may fail.

6.Children's castle. Restricts children's access to the window opening. It is built into the window handle or attached to the sash and frame and will not allow the window to open or will only open it for ventilation.

7.Turn blocker. It will not allow the window to open wider than the specified position; its functions are similar to those of a child lock, of which it is a type.

8.A multi-point lock can consist of one or more locks. They can be made with crossbars or without crossbars (with a latch). Locking hardware also includes traditional latches, hooks and pins.

9.Window handle. The standard one consists of a screw with fastening, a decorative lining and the handle itself. They can be made of plastic, aluminum, brass or wood (from cheap to expensive). Available in a wide range of colors. There are also anti-burglary handles - they have a special mechanism built into them that blocks the opening of the window due to external influence. The handles can be removable (installed only if you need to open them), with a lock (on a key), with a burglar-proof button. They also differ in shape - there are curved and flat.

10. Seals. They ensure a tight fit of the sash to the profile and retain heat. There are different types of window seals, which are classified by material. The most popular types of designs for sliding windows are brushed. This is a woven base with a polypropylene layer on the profile, and a brush, that is, special “hairs” coated with silicone. Rubber seals are also in demand - elastic, flexible, in a wide range of colors, not prone to deformation, with sections of different shapes. Seals can be silicone, thermoplastic elastomer, ethylene propylene (withstands temperature changes well, ultraviolet radiation), chloroprene (with a wide operating temperature range) and PVC.

11.Window hinges. The standard option is overhead structures, which can be one-piece or detachable, rotary or tilt-and-turn, anti-burglary with special plates that cannot be disassembled when the sash is closed. There are screw-in hinges that are mounted on threaded pins, or hidden hinges that are mounted so that they are not visible during installation. Hidden hinges are durable and allow the door to open 100°.

12.Window pins and strips are small locks, one of the parts of the locking mechanism. They ensure adhesion of parts when turning elements and a tight fit and pressure of the frame and sash.

13. Corner switch - necessary to ensure movement of the locking mechanism through the corner. Based on shaped steel plates.

14.Window locks. Necessary for opening, closing and tilting. Can be additional, intermediate and basic. The middle ones are located on the hinge side and are needed so that the frame fits the profile. The most common example of an additional lock is a multi-point lock. The main locks can be tilt-and-turn (from a fixed and movable part), rotary, without a comb, or hinged (for windows without an impost, a vertical crossbar between the sashes).

15. Rollers. Required for sliding windows. They represent a “road” that ensures smooth movement of the sashes, and consist of wheels with fastenings. Wheels can be nylon, metal, plastic or rubber. Rubber wheels are the most convenient to use. In addition, they are practically silent.

16. Stops. In their classic design, they are pads on the floor or handle, which help avoid damage. They can be metal with rubber or plastic, temporary or permanent, with or without a magnet.

17.Ventilation valves. Special ventilators that allow you to remove stagnant air from the apartment. The supply valve for plastic windows does not allow condensation to form.

18.Fittings for mosquito nets of plastic windows. The traditional option is a frame design. It can either be rigidly attached or installed in the opening using special hooks. If the mesh is bulky and heavy, loops are provided to secure it. There are also adhesive mosquito nets with adhesive tape as fastening, which will serve throughout the season, sliding ones, retractable according to the principle of sliding doors of a wardrobe, roller ones, which are wound, if necessary, on a special shaft.

19.Window sills. This element of the window design determines over 30% of the external attractiveness of the window. In addition, its functions include additional thermal insulation. They can be made from wood (expensive, stylish and high-status, requiring regular special care), from stone (the stone can be natural or artificial, with different textures, but in any case it will look luxurious), from PVC (plastic) - these options are available in different designs and colors, with different dimensions (length 4.05-6 meters, width - 110-600 mm, thickness - 18-22 mm). Window sills made of MDF and chipboard are also possible - they are based on slabs of wood chips, and on the outside there is a laminated coating (these materials do not require additional care, like wood, but are less durable compared to plastic). As for aluminum window sills, they are considered budget-friendly and are practically not installed inside buildings.

20.Window slopes are needed to create a complete look for the window opening. This category of fittings includes platbands - overlay strips with which the profile is formed, and window slopes - strips that are placed between the window profile and the wall. For platbands, the same materials are used as for the window sill (except for stone), and for slopes - plasterboard, plastic, aluminum or wood.

21. Flashing - a special device installed outside and protecting the integrity of the window waterproofing. Mounted directly under the window outside the opening. Castings made of copper and steel are considered the most practical, those made of aluminum are less durable, and those made of plastic and ceramic are the most fragile.

Types of fittings for sliding windows

Speaking about sliding fittings, about what kind of window fittings there are for plastic windows of this type, we note that auxiliary mechanisms for sliding windows include:

1.Parallel sliding. Can be installed on different types of window structures. The advantages of such fittings include tight pressure on all sides of the sash, the ability to control with just one handle, the ability to install on large structures, beautiful design, and automatic window stop. The most popular and durable system is the “slide-door” type, which allows you to open sliding windows according to the principle of a wardrobe: you need to click the lock and then pull the window sash to the left (right).

2.Folding parallel-sliding. It can tilt two doors at once, using one handle to turn it.

3. Lift-and-slide. The most reliable because it can withstand a sash weighing 400 kg.

Among the best companies producing window fittings, I would like to mention the Austrian company MASO. The main part of our products is hidden rotary and tilt-and-turn fittings. The range of fittings for MASO windows also includes anti-burglary components with 5 degrees of protection.

A modern approach to interior design involves the use of invisible fittings and non-standard opening schemes, for example parallel-sliding

Most plastic manufacturers equip their products with fittings from well-known European companies - Gretsch-Unitas (G.U.), FUHR, Hautau, MACO, Roto, Schüco, Ziegenia, Winkhaus, etc. The popularity of products from Chinese companies, for example GQ and G-Lock, is gradually growing.

Lines of window fittings differ primarily in functionality.

Tilt and turn windows

Today, the most popular are tilt-and-turn windows, the sashes of which can not only be swung open, but also tilted for ventilation at an angle of 10–20° to the vertical. At the same time, the flow of street air is directed upward, towards the ceiling, and the draft is felt much less. Tilt-and-turn fittings are 1.5–2 times more expensive than rotary (hinged) fittings, but it’s hardly worth saving, because in addition to comfortable ventilation, the first type of mechanism provides a tighter clamping of the sash to the frame (thanks to additional locking trunnions).

Premium equipment

The maximum range of fittings options for PVC windows includes:

1. Tilt and turn mechanism with protection against slamming of the sash.
2. Invisible adjustable lever hinges.
3. Multi-position slot ventilator.
4. Adjustable and burglar-resistant locking elements.
5. Devices for reducing friction during the operation of locks (special design of trunnions and/or strike plates).

When ordering, ask your consultant whether the tilt-and-turn window is equipped with protection against slamming due to drafts and a so-called error blocker - a hook that prevents the sash from falling out if the handle is turned incorrectly. If it is necessary to manufacture a large-sized structure, the issue of the load-carrying capacity of the hinges and the scissor tilting mechanism should be discussed.

Angular gears experience increased load and often come into contact with water, so it is desirable that they be made of a stainless alloy

As an option, tilt-and-turn windows can be equipped with slot ventilators (also known as micro-ventilators). Such devices allow you to tilt the sash 3–20 mm and lock it in this position by turning the handle down until it stops. They are single-position and multi-position. The former are inexpensive and can be mounted on any sashes, but the latter allow you to regulate the air flow, but increase the cost of the structure by 1.5–2 thousand rubles. and are not suitable for frame windows.

It is better to entrust adjustment and replacement of hinges to a specialist from the service center

Open position latches have also been developed for hinged (pivot) windows - advanced analogues of the familiar comb.

Sliding systems are used mainly in the manufacture of “French” windows, glazed balcony and terrace doors. The load capacity of such mechanisms reaches 400 kg

Mushroom-shaped locking pins and specially shaped strikers reliably lock the window and resist pressing of the sash well. However, to ensure the strength of the fastening of these elements, it is necessary to use profiles with reinforced reinforcement.

Plastic and wooden windows are equipped with almost the same fittings (only the hinges are slightly different). Devices for aluminum windows stand apart: they have a different drive for locking elements and a specific fastening in the fitting groove

A handle with a cylinder lock will prevent the door from being opened using a hook or wire loop. But first of all, this option is needed to prevent children from opening the window in your absence (some locks allow opening in slot ventilation mode). The cost of anti-burglary fittings is only 30–40% higher than that of conventional fittings, and its installation has little effect on the price of the window.

The main components of the fittings, for example, striker bars (1, 3), are made of galvanized steel and corrosion-resistant alloys, auxiliary parts, for example, open position comb clamps (2), are made of solid PVC or polyamide

Only an anti-vandal glass unit with triplex glued into the sash, an increase in the number of locking points, protection of the fittings from drilling and strengthening of the corner joints of the frame can radically increase the resistance of the structure to opening. Such an “anti-burglary package” will increase the cost of windows by 2.5–3 times, that is, it will cost more than shutters and bars.

Opening outwards. Today, many domestic manufacturers can offer top-hung and turning windows that open towards the street (with fittings from the Hautau Primat-A, MACO Espags, Roto Outward Opening lines, etc.). Such designs get along well with flower pots on the windowsill, do not tear curtains or break blinds. However, they also have serious disadvantages. So, you have to use hidden hinges and special expensive profiles (T-fold).

Windows with non-standard opening

Windows with non-standard opening arouse keen interest among visitors to construction exhibitions and manufacturers' salons. Such designs are in demand mainly in cottage construction. We will list and characterize the main systems, and in one of the following issues we will talk about them in detail.

Folding systems (“accordions”), for example those equipped with mechanisms from the Siegenia FS-Portal line, make it possible to close a wide opening, and in the open position they take up almost no space. The cost of such windows starts from 20 thousand rubles per 1 m². It is important to note that they are designed for use in temperate and warm climates.

In addition to traditional white handles, manufacturers offer products with wear-resistant polymer coatings such as gold, chrome, copper, etc.
