In this article, a plastic window device will be considered. It should be noted that the classical structure of modern windows is not dependent on the material of their manufacture.
PVC window construction
What is the structure of the plastic window?
It consists of:
- Frame. It is the main element and is mounted in the window opening of the building. Fittings and sashes are mounted on it.
- Sash. The part is a moving part, as it can open.
- Hardware. It includes constipation mechanisms that fix the valves and control them.
- Double-glazed window. It is leakproof. It includes several glasses that are fastened around the perimeter by means of special dividers.
Structure of profiles
The device of the plastic window has a complex configuration. The quality of the window frame itself depends on its quality . The profile characterizes the installation depth. Its indicator is systematized, and many firms produce windows with a depth of 5.8, 6 or 7 cm. Models are also thicker. Their installation 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 an empty cavity elongated along the profile. Depending on their number, profiles are subdivided into two-, three-, four-chamber, etc. Usually, firms involved in installing plastic windows present a cutaway plastic window device to the client. This allows the buyer to consider the internal structure of the product in detail.
Sometimes a non-hollow chamber is mounted inside the profile. 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. In the domestic market, designs with three cameras are in high demand. This configuration is not difficult.
What are plastic window profiles made of?
Plastic windows are made of different materials. The name PVC (polyvinyl chloride) we meet most often. But manufacturers can use both primary and secondary raw materials, as well as use a heterogeneous composition. When buying, it is better to pay attention to well-known companies producing plastic windows. They use primary material that is environmentally friendly. Such profiles have a high cost. Recycled materials contain harmful impurities. Sometimes heavy toxic metals are added to the composition.
Double-glazed windows
The device of a double-glazed window of a plastic window is leakproof. This construction cannot be disassembled. Assembly is carried out at the factory. A double-glazed window of PVC windows, as a rule, contains two or three glasses glued together around the perimeter. A special insert is inserted between them. Inside the structure contains a substance that absorbs moisture from the injected air or inert gas. Manufacturers fill the glass with air that has undergone thorough cleaning, or argon. Thus, dry and clean gas is present inside the structure.
In case of loss of tightness, moisture will penetrate into the glass unit, which will cause condensation. The gas will have increased thermal conductivity, and the design will cease to fulfill its function. It should be noted that dry air provides a high level of thermal insulation. For example, polystyrene is referred to as heat-insulating materials, because it is equipped with small pores and cavities containing air. The norm for thermal insulation of windows is considered to be a distance of 16 mm between the glasses. With an increase in this indicator, thermal conductivity increases.
Like a profile, a double-glazed window can contain a different number of cameras. If two glasses are included in it, then it has one camera, and if three, then it will be two-chamber. As a rule, two-chamber structures are mounted in residential premises. They have a standard installation depth of 24 mm. Furthermore, the thickness of the glasses is 4 mm, and the distance between the glasses is 16 mm. This configuration can reduce noise by 34 dB.
Hardware for windows made of plastic
Let us begin to consider what makes the device of plastic windows functional. The hardware manages the frame. It should be noted that its mechanism is complex.
How does a plastic window lock device function?
Parts of the configuration are installed along the inner perimeter of the window sash. Entering into interaction, they provide a different position of the window frame. At the same time, their work is distinguished by clarity. The locking device of the plastic windows has a large number of adjustments. For example, the position of the sash can vary not only in height, but also horizontally and diagonally. Sagging can be avoided by applying a micro-lift installed under the sash, as well as using other adjustments.
The mechanism of the mechanism of plastic windows contains two plates of steel. They are located in a groove specially designed for them, running along the entire profile. The inner plate is called a transmission bus. It is she who is set in motion by turning the handle.
The transmission bus contains trunnions. These are the constipation elements that hold the leaf in a predetermined position. As soon as the handle is rotated, the trunnions fall into certain slats on the sash located on the other side. The frame is held tightly closed. When the handle moves up, the trunnions located below are closed. Therefore, the sash is easy to set to the ventilation mode. In the upper part of the window there is another element of accessories, called “scissors”. It gives you the opportunity to slightly open the window.
As a rule, the economical class of a product has a standard set of options. You can install a basic package with a minimum number of features or choose a multifunctional model. It all depends on financial capabilities and taste.
As a rule, additional options provide:
- child protection;
- sash push-up protection;
- airing the room;
- fixation of the valves in different positions;
- the presence of external handles, etc.
It also offers accessories against burglary, which has increased strength and can serve as reliable protection. It is equipped with lockable handles.
Like any mechanism, this device can also fail, and repair of plastic windows in this case is inevitable. It is not advisable to repair it yourself. It is necessary to consult a specialist.
The service life of the hardware 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 designs, it is recommended to pay attention to the slope of the plastic windows. Errors in the selection of this element can lead to the formation of condensation on the glass or their freezing. The most optimal option is the installation of PVC slopes.
Such a device has the following advantages:
- differs in ecological purity and do not demand special leaving;
- color can be chosen to taste;
- the surface of PVC is easy to clean, no stains from detergents remain on it;
- plastic slope has a long service life.
In construction practice, several methods of installation of structures are used. Three are widespread:
- the use of special panels;
- installation of slopes made of plastic ;
- installation of drywall 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 curtains
This method of fixation makes it possible to fix the curtains both above the window opening and in it. The system is usually mounted on windows, but there are multi-purpose mechanisms.
Open mounts for curtains have a variety of:
- Mini system mount. It is suitable for sashes and frames.
- The standard type that is mounted above the window opening.
- Attic view. It is designed for windows of complex configuration.
Despite the fact that there are many types, the principle of operation of the mechanisms is the same. The curtain is wound on a shaft fixed between the holders. The curtains are controlled by a chain or a spring mechanism. In the second case, the holder is mounted on a bracket located below. The curtain is pulled down and fixed at a level that provides the necessary dimming of the living room.
Often, hook rails are used to fix the device. Also use double-sided tape for installation. It has its minus, which consists in the fact that the adhesive layer begins to melt during the heat. Hangers are also used. But they are not suitable for all frames. The unified method is the fastening of curtains using screws and screws. The diameter of the shaft depends on the width of the blade. For curtains in rolls, strong slats are required. Otherwise, the system may become deformed or broken.
Closed curtains
A few 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 between this design is the presence of the box. This part contains side plugs and gives the configuration a neat appearance.
An important role is played by the size of the box. Installation of roller blinds with a mini-system on plastic windows does not prevent the closing and opening of the shutters. When using heavy roller blinds, it is necessary to use a large box and a strong shaft. Such mechanisms are not always placed above the opening, especially if the window is located high. In this case, the installation of the system is carried out on the ceiling. In this case, the guides are discarded. If possible, it is recommended to install them. Devices will prevent deformation of the curtain web, help to avoid displacement, provide the system with the necessary movement.
How to fasten a curtain on a window sash?
When attaching the curtains, attention must be paid to the shaft diameter and the length of the brackets. The longer the part, the greater the amount of winding it will provide. Therefore, when choosing curtains from loose or dense material, long brackets should be used. Roll mechanisms operate silently. The appearance of strong sounds indicates that the design is defective or improperly assembled.
Recently, many new solutions have appeared in the field of roller blinds. Manufacturers offer a design in which the boxes are mounted so that they move with the curtain. This makes it possible to control the mechanism in two directions. There are also temporary configurations on special bars. Their fastening is carried out by means of adhesive tape. They make it possible to move the system if necessary.
This design is used for decor of country houses. Only specialists can figure out the variety of types of systems. Before starting complex work, it is recommended to discuss all issues with a professional.
