The device of a plastic window: features, the scheme and mechanisms

In this article, we will consider the construction of a plastic window. It should be noted that the classical structure of modern windows does not depend on the material of their manufacture.

Construction of PVC windows

What is the device of the plastic window?

It includes:

• Frame. It is the main element and is mounted in the window of the building. It fastens the fittings and flaps.
• Shutter. The part is a movable part, since it can be opened.
• Fittings. It includes the mechanisms of constipation, which fix the flaps and control them.
• Double-glazed windows. It is notable for its tightness. It includes several glasses, which are fastened around the perimeter by means of special dividers.

Structure of profiles

The device of a plastic window has a complex configuration. Its quality depends on the quality of the window frame itself. The profile characterizes the mounting depth. Its indicator is systematized, and many firms produce windows with a depth of 5.8, 6 or 7 cm. There are models and thicker. Their mounting depth reaches 13 cm. They are designed for wide and large double-glazed windows.

Also profiles differ in the number of internal cameras. A chamber is called an empty cavity, elongated along the profile. Depending on the number of profiles are divided into two, three, four, etc. Typically, companies involved in installing windows of plastic, represent the customer a plastic window device in a section. This allows the buyer to examine the internal structure of the product in detail.

Sometimes inside the profile is not built a hollow chamber. It contains reinforcing material. The more cameras in the profile, the higher the quality of the product. This is explained by the fact that multi-chamber windows have a high level of thermal insulation. The domestic market is in high demand using designs with three cameras. This configuration is not complicated.

What are the profiles of plastic windows made of?

Plastic windows are made of different materials. The name of PVC (polyvinylchloride) we meet most often. But producers can use both primary and secondary raw materials, as well as use a heterogeneous composition. When buying is better to pay attention to well-known companies for the production of plastic windows. They use a primary material that is environmentally friendly. Such profiles have a high cost. Secondary raw materials contain harmful to health impurities. Sometimes heavy toxic metals are added to the composition.

Double-glazed windows

The device of a double-glazed window of a plastic window differs tightness. This construction can not be disassembled. Assembly is carried out at the factory. The PVC windows, as a rule, contain two or three glasses glued together along the perimeter. A special insert is inserted between them. Inside the structure contains a substance that absorbs moisture from the air pumped inside or inert gas. Manufacturers fill the double-glazed window with air that has undergone thorough cleaning, or argon. Thus, dry and clean gas is present inside the structure.

In the event of loss of airtightness, the moisture will penetrate into the unit, causing condensation. The gas will have increased thermal conductivity, and the design will cease to fulfill its function. It should be noted that the dryness of the air provides a high level of thermal insulation. For example, plastic foam is referred to thermal insulation materials, because it is provided with small pores and cavities containing air. The norm for the thermal insulation of windows is a distance of 16 mm between the panes. With increasing this index, the thermal conductivity increases.

Like the profile, a double-glazed window can contain a different number of cameras. If it includes two glasses, then it has one camera, and if three, it will be a two-camera. As a rule, two-chamber structures are mounted in living rooms. They have a standard mounting depth of 24 mm. At the same time, the thickness of the glasses is 4 mm, and the distance between the panes is 16 mm. This configuration can reduce noise by 34 dB.

Accessories for plastic windows

Let's start by examining what makes the functional arrangement of plastic windows. The accessories manage the frame. It should be noted that its mechanism is complicated.

How does the plastic window lock device work?

Parts of the configuration are installed on the inner perimeter of the window sash. When interacting, they provide a different position of the window frame. At the same time, their work is distinguished by clarity. Locking device of plastic windows has a lot of adjustments. For example, the position of the leaf can vary not only in height, but also horizontally and diagonally. The sagging can be avoided by using a micro-elevator installed under the sash, and also with the help of other adjustments.

The device mechanism of plastic windows contains two plates of steel. They are located in a groove specially designed for them, which runs along the entire profile. The inner plate is called the transmission bus. It is set in motion when turning the handle.

The transmission bar contains trunnions. These are the elements of the constipation that hold the leaf in the given position. As soon as the handle turns, the trunnions fall into certain slats on the sash located on the other side. The frame is tightly held in the closed position. When the handle moves upwards, the trunnions located below are closed. Therefore, the leaf can be easily set to the ventilation mode. In the upper part of the window there is another furniture element, called "scissors". It allows you to open the window a little.

As a rule, the economy class of the product has a standard set of options. You can install a basic package with a minimum of options or you can select a multifunctional model. Everything depends on financial possibilities and taste.

As a rule, additional options provide:

• Protection of children;
• Push-up prevention;
• Airing the room;
• Fixing the leaflets in different positions;
• The presence of external handles, etc.

Also offered anti-burglary hardware, which has increased durability and can serve as a reliable protection. It is equipped with lockable handles.

Like any mechanism, this device can fail, and the repair of plastic windows in this case is inevitable. It is not advisable to fix it yourself. It is necessary to consult a specialist.

The service life of the accessories can be increased if the windows are serviced in a timely manner: lubricate them and clean the mechanisms.

Installation of window slopes

When installing new structures it is recommended to pay attention to the device of slopes of plastic windows. Errors in selecting this element can lead to the formation of condensation on the panes or their freezing. The most optimal option is the installation of slopes from PVC.

Such a device has the following advantages:

• It is environmentally friendly and does not require special care;
• Color can be chosen to taste;
• The surface of PVC is easy to clean, there are no stains from detergents;
• Plastic slope has a long service life.

In building practice, several methods of mounting structures are used. Widely distributed three:

• Application of special panels;
• Installation of slopes from plastic ;
• Installation of gypsum board products.

Roller blinds on plastic windows

Curtains in rolls have high functionality. They give the apartment a unique style and contribute to the creation of comfort. That is why such products are in great demand.

Features of the open method of fastening the curtains

This method of fixing makes it possible to fasten the curtains both above the window opening and in it. The system, as a rule, is mounted on windows, but there are also multi-purpose mechanisms.

Open fasteners for curtains have the following versions:

• Mounting of the mini-system. It is suitable for wings and frames.
• A standard type that is mounted above the opening of the window.
• Mansard view. It is designed for windows of complex configuration.

Despite the fact that there are many types, the working principle of the mechanisms is the same. The curtain is wound on a shaft fixed between the holders. The curtains are controlled by means of a chain or mechanism on a spring. In the second case, the holder is mounted on the bar located below. The blind is pulled down and fixed at a level that provides the necessary dimming of the living room.

Often, fixing the device using guides with a hook. Also use double-sided adhesive tape for installation. It has its disadvantage, which is that the adhesive layer begins to melt during the heat. Hangers are also used. But they are not suitable for all frames. The unified way is the fastening of curtains by means of screws and screws. The diameter of the shaft depends on the width of the blade. For dimensional curtains in rolls require strong strips. Otherwise, the system may be deformed or broken.

Closure of closed type curtains

Several years ago it was believed that the closed type of fastening is applicable only to plastic windows. In fact, such a device for curtains on plastic windows is also used in structures made of wood and aluminum. The system has different sizes, but this does not affect the attractiveness and functionality. The main difference of this design is the presence of the box. This part contains side plugs and gives the configuration a neat look.

An important role is played by the size of the box. The installation of roller blinds with a mini-system on plastic windows does not prevent the closing and opening of the doors. When using heavy roller blinds, a large box and a strong shaft are required. Such mechanisms are not always placed above the opening, especially if the window is high. In this case, the system is mounted on the ceiling. In this case, the guides are discarded. If possible, they are recommended to be installed. Devices will prevent the deformation of the curtain fabric, help to avoid displacement, provide the system with the necessary movement.

How to fix the curtains on the sash of the window?

When attaching the curtains, you must pay attention to the diameter of the shaft and the length of the brackets. The longer the part, the greater the amount of winding it will provide. Therefore, when choosing curtains of loose or dense material, you should use long brackets. Rolling mechanisms work noiselessly. The appearance of strong sounds indicates that the design is defective or incorrectly assembled.

Lately, in the field of roller blinds, many new solutions have appeared. Manufacturers offer a design in which the boxes are attached with the account that they move with the curtain. This makes it possible to control the mechanism in two directions. There are also temporary configurations on special slats. Their fastening is carried out by means of an adhesive tape. They make it possible to move the system if necessary.

This design is used for decorating country houses. In a variety of types of systems will help to understand only experts. Before starting a difficult job, it is recommended to discuss all the issues with a professional.
