This set of mechanisms allows us to easily open and securely close the window
Fittings for plastic windows are not only handles and hinges, as it might seem at first glance. Even the simplest window hides a complex mechanism inside that is responsible for pressing the sash to the frame, opening in different modes, ventilation and performing a number of other functions. So we’ll figure out what kind of mechanism this is, what elements it consists of, and how to maintain it for maximum efficiency.
Studying the “window muscles”
Lesson 1. Basic elements
Almost any fittings for PVC windows that are responsible for setting the sash in motion (it’s not for nothing that they are figuratively called “window muscles”) are created according to a single scheme. All components can be divided into two groups - basic and additional.
The main part of the fittings provides:
- pressing the sash to the frame at several points;
- blocking the opening of the sash from the outside;
- opening the sash in a rotating position;
- opening the sash in a folding position.
Sometimes a folding element is not included in the design. This reduces the cost and simplifies the fittings complex, but reduces the functionality of the window - you can no longer install it for ventilation.
List of main fittings:
| Illustration | Element |
 | Sash strapping with locks. The system is a complex of mechanisms that is driven by turning a handle. Plate levers around the perimeter drive the mash pins (cylinders), which, when closing, engage strikers mounted on the frame. Fitting systems with increased burglary protection are equipped with trunnions of complex shape (not cylinders, but hooks or mushrooms), as well as more reliable strikers. |
 | Central drive and window handle. An element that controls the locking part of the fittings. A square socket is made in the drive into which the handle pin is inserted. The handle can be either single-sided or double-sided. When it turns, the locking pins and other elements (blockers, ventilators, etc.) are set in motion. |
 | Loops. Placed on the side of the sash, they ensure its movement relative to the frame. The hinges usually bear the main load, so they are secured in the profile and reinforcing body using reliable fasteners. The hinges contain elements for adjusting the fittings. They are screws, the rotation of which makes it possible to move the sash a few millimeters to eliminate misalignment. A hidden loop can also be used. It is located in the gap between the frame and the sash and has a complex design. Hidden hinges are not visible when the window is closed, so they are chosen mainly for design reasons. |
 | Transfers. Elements that transmit force from the central lock to other parts of the fittings. Main:

Lesson 2. Additional elements
The mechanism for PVC windows can include not only basic, but also additional fittings. Typically, the presence of such elements allows you to open the sash in different modes for ventilation, or increases the comfort of using the system as a whole.
The most common types of additional elements are:
| Illustration | Element | |||||||||||||||||
 | Step ventilation. A part with a toothed part that is built into the fittings. Each tooth on the element corresponds to a specific position of the sash, therefore, by turning the handle, we can choose the intensity of ventilation ourselves. |
|||||||||||||||||
 | Micro-ventilation. A similar element, but with less functionality: installing such a part adds only one additional provision for ventilation. When the handle is turned 45°, the sash opens a few millimeters around the perimeter, letting in a small amount of air. This mode is convenient to use in winter time so as not to overcool the room. |
|||||||||||||||||
 | Erroneous opening blocker. A useful detail primarily for a balcony door. When active, it prevents the window from being opened in both the tilt and tilt positions at the same time. In the absence of a blocker, there is a risk of the sash falling out of the frame and hanging on one hinge. |
|||||||||||||||||
 | Microlift. Placed at the bottom of the sash or opposite the handle. When closing, it lifts the structure, making it easier to lock the fittings. In addition, if there is a microlift, the sash does not sag under its own weight, which means it requires adjustment less often. |

Fittings for plastic windows are a set of elements with which the window is opened and closed. That is why when choosing a window you should pay attention special attention on the quality of the fittings used. The more reliable the design, the longer it can last without repairs or replacement.
What is included in window fittings?
The design of window fittings provides for the presence of such elements as:
- window handle that controls the entire operation of the fittings from one point;
- corner element, with the help of which other structural elements are connected;
- a locking bar that presses the window against the sash using adjacent rollers;
- scissors, an element necessary for tilting the window sash;
- window hinges, allowing you to attach the window to the frame and smoothly open and close it;
- additional scissors necessary to strengthen and increase the performance of element 4;
- additional corner strip to enhance the work of the structure;
- a strike plate located on the window frame and allowing the rollers to operate to provide the best connection between the sash and the window frame;
- a pin or roller that ensures the window sash is pressed as tightly as possible to the frame;
- an additional set of locking elements that allows the window to be tightly pressed to the frame.
Additionally, the fittings may include the following elements:
- anti-burglary protection of windows from penetration from the street;
- Child locks provide child protection.
Types of window fittings
Plastic fittings for windows vary according to the type of opening. It could be:
- rotary, that is, the window opens in the standard way;
- folding, opening the window up or down;
- tilt and turn, that is, opening the window in two positions. Typically to the side and down;
Pivot fittings are optimal for balcony doors, tilt fittings for roof windows, and tilt and turn fittings for windows in rooms.
Major manufacturers of high-quality window fittings
Window fittings are produced by a large number of companies, but only a few of them can be highlighted:
- Roto company (Germany). The only company that provides a 10-year warranty on manufactured elements. The fittings are characterized by increased quality, reliability and wide range products interacting with each other;
- Maco company (Austria). It mainly produces hidden fittings, that is, hidden inside the window, and also specializes in the production of anti-burglary security elements with at least 6 degrees of reliability;
- Siegenia (Germany) produces universal fittings suitable for both PVC windows and wooden products. Upon customer's request, fittings for non-standard size windows can be manufactured;
- the Winkhaus company (Germany) produces fittings based on its own patented design, which differs from competitors in the special design of the rollers, which allows the necessary adjustments to be made easily and smoothly.
When choosing a manufacturer, you should base your choice on the quality of the products and the company’s product range.
You must select window fittings according to the following rules:
- first of all, you need to decide how the window should open;
- measure the window dimensions and select sets that clearly match the main parameters;
- it is more advisable to buy accessories from the widely used companies listed above;
- It is not recommended to purchase plastic products (they have a very short service life). It is better to buy metal components and cover them with overhead caps in visible places;
- There should be no “burrs” on high-quality fittings, that is, the metal should be even and smooth;
- A high-quality element of fittings must have at least two holes for subsequent fastening.
Installation and adjustment of window fittings
After selecting fittings for metal-plastic windows, it is necessary to carry out its installation and final adjustment.
DIY fittings installation
Installation or replacement of plastic window fittings occurs according to the following scheme:
- if fittings are replaced, then at the first stage the old structure is dismantled;
- a new set of accessories is laid out on the table in in the necessary order(a diagram of the mutual fastening of fittings is shown in the figure at the beginning of the article);
- fastening the fittings begins with the main and additional corner strips;
- then locking strips are installed along the perimeter of the window sash;
- Now you can proceed to attaching the main and additional scissors;
- The hinge components are mounted on the window sash and frame. The hinges are connected and the window is suspended;
- strikers are installed on the window frame;
- a handle and the necessary additional fittings are mounted.
The window fittings kit includes not only the main elements, but also the necessary fastenings and an installation diagram.
Adjusting window fittings
After installation, the final adjustment of the PVC window fittings is made. This process will require the following tools:
- screwdriver of the required size;
- hex wrench;
- pliers.
You can adjust the position of the window sash in three directions:
- up – down;
- forward - backward;
- right - left.
The fittings are adjusted according to the standard scheme:
- decorative caps are removed from the necessary elements of fittings;
- the adjusting screws are tightened or loosened until the problem is completely eliminated.
If the window sash is not installed correctly in the upper or lower part, then adjustment is made using the screws of the upper and lower hinges, with the bolt being tightened at the top and loosened at the bottom. It is necessary to adjust the horizontal of the sash gradually, making several turns of both screws and checking the correct position.
If the window sash does not fit tightly to the frame on the side, then the position must be adjusted using the screws located at the bottom of the hinges.
To adjust the fit of the window to the frame, it is necessary to loosen or tighten the fit of the trunnions.
A strong clamp ensures a tight fit of the window and is mainly used in the cold season. Weak pressure is relevant for hot periods.
Before purchasing window fittings, special attention should be paid to the quality of the products and the required dimensions. You can install the structure yourself, using the recommendations of specialists and the instructions included with the kit. Any fittings require periodic maintenance, including cleaning and lubrication.

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 diagramWindow fittings are:
- Loops. Or the so-called loop group, which consists of lower and upper loops.
- Mechanical locking window elements.
- 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:
- Brush. Their special feature is silicone “lint”, which creates good sound insulation and excellent temperature retention.
- Rubber. Elastic and durable, have different shapes sections and are made in a multiple range of different colors.
- Silicone. They have excellent temperature resistance.
- Thermoplastic elastomers.
- Ethylenepropinelic. Like silicone, they are well resistant to temperature fluctuations and ultraviolet radiation.
- Chloroprene.
- PVC seals.
- Window hinges.
May be:
- Standard invoices.
- Screw-in loops. Installed with threaded pins or mounted into a profile. Loops of this hidden type have long term services and are capable of opening the window sash by 100°.
- Window locks:
- Stops. Protection, which is presented in the form of temporary or on an ongoing basis located on handles, on the floor or any other surface, and protects windows from damage. One of the most useful secondary things actually.
- Mosquito nets. 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 are three types:
- 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.
- Folding parallel-sliding. Allows you to open both doors at once using just one handle.
- 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:
- Ease of use, minimal maintenance requirements.
- Long term.
- 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 truly 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.
When choosing and purchasing PVC windows, the modern consumer first of all pays attention to functional features and performance qualities - this is the level of heat and sound insulation, appearance. But the buyer is least interested in the quality of fittings for plastic windows, and, as practice suggests, this is in vain.
Professionals involved in plastic window systems are confident that 50% of how a window will work depends entirely on the fittings. It is the fittings that determine whether the window structure will be sealed, reliable and burglar-proof. It is known that components account for about 15% of the price of the entire window, which means you need to know what the best fittings for plastic windows are, how to choose a reliable manufacturer and how not to buy what the manager is trying so hard to sell.
What is meant by fittings for PVC window systems?
Window fittings are a set of components that support the frame and make it possible to open or close the window. Also, with the help of fittings, a tighter fit of the frame to the profile is ensured.
In general, fittings include various handles, sealing elements, locks, latches and much more. People who are far from everything related to window solutions also include ventilation parts, mosquito nets, and sometimes window sills as accessories. Naturally, these parts are not accessories. However, when purchasing windows, you also need to pay attention to them.
Types of fittings for plastic windows
Depending on how the window sashes open, there are several types of fittings. Thus, we can distinguish rotary systems, as well as tilt-and-turn systems - such solutions are most often used in conjunction with windows and balcony doors, which can be opened using the usual swing method or by tilting. There are also parallel-sliding fittings - they are used only on sliding window-door structures.
Some are sure that there are separate window fittings for windows made of wood, plastic or aluminum. In fact, this is not true and dividing the components in this way is not entirely correct.
PVC window handles
There are many options for these parts. They vary in colors and materials. However, first of all, these components are divided among themselves according to functionality.
A standard window handle is the most common and affordable part. Such components do not contain any additional features. With this handle you can open window frame only by swing or tilt-and-turn method.
These simplest components for plastic windows consist of a screw, which is attached to a plastic frame through a decorative overlay, under which the fastening elements - self-tapping screws - are hidden, as well as a handle.
These parts can be made from various materials and flowers. The most affordable are plastic handles. Then there are aluminum ones. The most expensive products that are offered with luxury windows are made of brass, copper or wood.
There are also special anti-burglary handles. In appearance, they are no different from ordinary ones, but structurally they are made in such a way that they do not allow attackers to open the window from the street side. Using a special mechanism, any hacking attempts are blocked.
Removable handles are purchased in cases where there are small children in the family. There are many known cases of children falling out of windows. These components for plastic windows will help avoid these tragic situations. These solutions are also relevant if the window will not be opened very often. This part has a simple design. First, a special socket is fixed, and a handle is already inserted into it. The socket is permanently located on the frame, but the handle should only be used when you need to open the window.
Window handles with a lock are also a relevant solution for families with children. In order to open the frame completely, you first need to remove the handle lock - for this there is a lock on the body. To tilt the sash, you do not need a key - here the handle simply turns and then you need to pull it a little, as in any window.
Handles with burglar-proof buttons are also anti-burglary fittings for plastic windows. To open a window equipped with such a system, you must first press the button. These solutions seem convenient because there is no key to lose. But on the other hand, this is unsafe - a child can easily press a button that is interesting to him.
The curved handle is perfect for those windows that will only open outward. It differs from the ordinary one only in a higher level of comfort. When opening the window, the edge of the handle will not touch
There is also a balcony hook - this part is installed on the door block from the balcony side, and an ordinary handle is installed inside.
Window seals
These parts are also fittings and they perform a very important role in the design. important functions. It depends on them whether the window will close hermetically and whether the room will be warm. These products differ in materials.
Foam rubber seals are used only with wooden windows. The foam itself is very fragile and also perfectly absorbs moisture. That is why, in our climate, such a seal will last less than a year. These materials are produced in varying thicknesses - from 2-3 mm to several centimeters.
Polyethylene seals, like foam seals, are used primarily with wooden windows. They are made in the form of self-adhesive products or without an adhesive layer. These seals are slightly better than foam rubber ones - they do not absorb moisture and also retain their shape much better. Such products will last much longer.
Brush sealing products are a special base that is mounted on a profile, as well as from a brush. Most often, most manufacturers use fabric materials as a base. To make the fabric tough and durable, it is covered with a polypropylene layer. The brush is lint. In order to increase moisture resistance, they are coated with silicone. Such parts vary in color - black, white, gray and other colors are widely available.
PVC seals are made of plastic. The quality of this product is very low. IN summer period Over time the material becomes soft. In winter, on the contrary, it becomes very fragile. These products do not differ in service life.
The most popular This will be confirmed by managers; just visit any hardware store for plastic windows and doors. Among the advantages of rubber-based products are high strength and heat resistance. In addition, rubber seals are very elastic and flexible - due to this, any deformation is completely eliminated.
There are several types of rubber seals. Products made from silicone are the best in their class. They are made from environmentally friendly pure material, are not afraid of moisture or exposure to aggressive environments. Available in white or grey. Thermoplastic elastomer products are significantly inferior to silicone ones. Products made from ethylene propylene have a long service life.
Window hinges
These fittings vary according to the type of installation. All types of hinges are applicable for all types of window structures.
So, an overhead or standard hinge is suitable for both wooden, metal and PVC windows. The product consists of two metal cards. There are detachable and one-piece hinges, rotating or rotating with the possibility of tilting the design for a plastic window. Often, after installation, the loop is covered with a decorative trim.
Screwed directly to the frame with special threaded pins. In this case, one loop can have up to 6 pins. The more there are, the more reliable the design will be. Previously, such screw-in hinges were used exclusively with wooden window structures. Today they are also made for PVC window products.
Used for structures of any type. But hinges for wooden and plastic windows are radically different. Among the advantages of these products is not only their hidden installation. These solutions have long term operation and allow you to open the frame to a larger angle. In addition, these hinges make it difficult for an attacker to gain access to the room through a window. And one more advantage - no draft penetrates into these loops.
The anti-burglary loop is 100% secure. The set includes special anti-burglary plates that prevent entry if the window is closed.
Locks are most often supplied complete with a handle. There are single-point and multi-point locks. According to the closing method, a multi-point lock can be bolted or without a bolt.
This is a slight constipation that looks like a fungus. This is one part of the locking mechanism. Under the action of the locking mechanism, the trunnions can rotate and catch other parts. They contribute to a tighter closure of the sash.
Plank
Those who have never dealt professionally with plastic windows do not know what kind of fittings there are for plastic windows other than standard well-known elements. But there are many more different parts in the kit.
The bar allows the sash to fit more tightly to the profile. Often the bar can also provide additional security against burglary. Most manufacturers often use only two strips per window, however, the more of these parts, the better.
For those who do not know what the best fittings for plastic windows are, there are counters that are responsible for burglary protection, as well as tilt-and-turn ones. In addition to its main tasks, the strip is also the fulcrum for the swing-out sash.
Corner switches
These elements drive the locking mechanism of the window system through the corner. Structurally, it is a set of plates made of elastic steel grades that all work together. These parts can also be burglar-resistant.
Scissors
These elements are used for tilt-and-turn structures. They are designed to fix the sash in the open position. In addition, scissors make the locking mechanism easier to operate.
Constipation
These components of window fittings are designed to open, close, and tilt the window sash. The mechanism is activated by rotating the handle, which moves a special lever. Already from this lever the entire locking system is activated. There are basic constipation, as well as additional and secondary.
Middle locks can be found at the bottom of the window profile and at the side on the side where the hinges are located. Its main function is to press the frame against the profile. The part can be connected to tilt-and-turn locks, scissors and other mechanisms.
Additional locks are called locks, and the main locks come in various designs. Thus, a distinction is made between tilt-and-turn constipations, rotary or pin-type.
The best manufacturers of window fittings
People inexperienced in choosing plastic windows often ask the same question on various forums and in social networks- what is the best fittings for plastic windows? Consulting managers praise what they sell, but very often buyers are faced with frankly low-quality components. Let's try to figure out which products are considered the best and which manufacturers can be trusted.
If you need high-quality fittings for plastic windows, reviews can tell you about the quality. For example, judging by the analysis of opinions, it is not recommended to buy a window with domestic or Turkish or Chinese fittings.
Roto - products with true German quality
Products from this manufacturer meet all necessary standards and also have high level reliability and durability. In addition, Roto is the only company on the market that guarantees the quality of window components for 10 years. The product differs from existing analogues in the flat tongue of the locking mechanism.
This fittings have some advantages - during the closing process, almost no effort is required, and the force itself on the parts of the locking mechanism is distributed over the entire surface.
All parts are made of high-quality materials and have a simply enormous service life without the need for adjustments.
Maco
Mako fittings for plastic windows are produced in Austria. The products of this brand also have the highest level of quality and are considered the best on the market. The company is known for producing hidden mechanisms for tilt-and-turn and turning window structures. In addition, the company's products significantly improve the appearance of the window structure. The company's catalogs contain elements that can be used for external opening.
The range includes anti-burglary fittings "Mako" for plastic windows. It reliably protects against break-ins and penetrations with additional trunnions that improve locking. Available with six security elements.

All accessories are easy to use and install.
Resume
The rating of accessories for plastic windows shows that German brands are in first place. When managers try to sell a window with domestic fittings and promise high quality, you should not believe them - literally in six months such a window will need to be adjusted. Don't trust consultants. Now it’s clear what the best fittings for plastic windows are and no one will deceive the average buyer anymore.
Window fittings for plastic windows are complex mechanisms, which 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 (upper and lower);
- mechanical locking elements;
- components for turning the window through the 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:
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:
- Turn limiter. Needed to fix the window in the open extreme position. Can be installed with an additional brake.
- 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, which are similar to window structures.
- 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.
- 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.
- Folding scissors 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.
- . 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.
- 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.
- Multi-point lock may consist of one or more constipation. They can be made with crossbars or without crossbars (with a latch). Locking hardware also includes traditional latches, hooks and pins.
- 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 when 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.
- Seals. They ensure a tight fit of the sash to the profile and retain heat. There are different ones, which are classified according to materials. 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. Also in demand rubber seals- elastic, flexible, in a wide range of colors, not prone to deformation, with sections of different shapes. Seals can be silicone, thermoplastic elastomers, ethylene propylene(stands up well to temperature changes, ultraviolet radiation), chloroprene(with a wide operating temperature range) and from PVC.
- Window hinges. Standard option - invoices structures that 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 installed on threaded pins, or hidden, mounted so that they are not visible during installation. Hidden The hinges are durable and allow the door to open 100°.
- Window trunnions and trims— small constipations, 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.
- Angle switch- necessary to ensure movement of the locking mechanism through the corner. Based on shaped steel plates.
- 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 for the frame to fit against 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).
- 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 silent.
- 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.
- Ventilation valves. Special ventilators that allow you to remove stagnant air from the apartment. does not allow condensation to form.
- Accessories for mosquito nets 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 ones with adhesive tape as a fastening, which will serve throughout the season, sliding ones, which move away according to the principle of sliding wardrobe doors, and roller ones, which are wound, if necessary, on a special shaft.
- 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 less durable than plastic). As for aluminum window sills, they are considered budget-friendly and are practically not installed inside buildings.
- Window slopes are needed to create the finished look of the window opening. This category of fittings includes platbands- overhead strips, with which the profile is formed, and - strips, which 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.
- Low tide- 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:

What to look for when choosing
If you still have doubts about what fittings to choose for PVC plastic windows, how to choose so as not to make a mistake, then you should give preference products from trusted manufacturers made from high quality materials. Do not forget that reliable operation and durability of the entire window structure depend 50% on the quality of the fittings.
After all, if you look at a plastic window structure quickly, you will immediately remember either the profile or the double-glazed window, but almost no attention is immediately paid to the fittings. But it is precisely these elements, invisible at first glance, that determine the reliable operation and overall quality of the entire structure, since it is the fittings that bear the main dynamic and mechanical loads. Therefore, the most important thing in such elements is the accuracy of the design, exact adherence to all geometric dimensions and transitions (which is impossible to ensure in the conditions of handicraft production).
When choosing high-quality fittings for a metal-plastic window, you need to be guided by the following criteria:
- ability to withstand high and prolonged loads;
- comfort of use, ease of operation, lack of specific care requirements;
- durability and reliability. These indicators are ensured by the mechanical strength of the structure and resistance to corrosion;
- availability additional functions in accordance with customer requirements (these are anti-burglary elements, child locks, and so on).
Do not forget that the cost of high-quality fittings is up to 15% of the total cost of the structure, but saving on its purchase is highly undesirable. It is better to immediately equip the window with fittings from trusted manufacturers (most often these are German companies) than to eliminate emergency situations caused by a malfunction of components, or carry out unscheduled adjustments with the involvement of specialists. In addition, low-quality fittings wear out very quickly, and consequently, window sashes lose the reliability of their fixation and cannot maintain the initially specified heat and sound insulation values.
