Comparison of plastic windows profiles

Plastic windows firmly take a leading position. They are distinguished by a high level of heat and sound insulation, in addition, they provide the opportunity to choose accessories, a method for opening a window and the color of the profile. You can also choose a double -glazed window with the required number of cameras. But few people think that it is the window profile that provides the strength and durability of the entire structure. In the article, we compare the profiles of plastic windows different in characteristics and manufacturers.

General information about the profile of plastic windows

On average, the thickness of the profile of plastic windows varies from 58 mm, and to 86 mm, but some companies produce products up to 127 mm wide.

Its inner part is hollow, but separated by jumpers creating several air chambers. Special technical calculation determines their size and location. The wider the profile, the greater the number of cameras in it, increasing thermal protection properties. Another characteristic of the profile system of the filling width, which determines what type of double -glazed windows can be installed in the profile. They are one- or two-chamber species, the width of the glass in the standard double-glazed window is 4 mm (M1 brand).

 

Each cavity has its own purpose:

• for outflow of water;
• furniture mounts;
• is responsible for strength, etc.

 

The color of the profile can be varied, the color is applied in several ways:

• the coemusive method - multilayer films create a barrier that allows the product to withstand dynamic loads without damage;

• lamination - with imitation of texture, for example, under marble or wood;
• monophonic staining.

 

PVC profile characteristics for plastic windows

 

Material

• This product is made from a variety of plastic of white polyvinyl chloride.
• The material is highly resistant to chemical effects by alkalis, solvents, acids and mineral oils.
• It is harmless to man and the environment.

• Due to its distinctive properties, polyvinyl chloride allows you to make frames for double -glazed windows not only a rectangular or square shape, but also in the form of arches, triangles, circles and so on. Thus, giving absolutely any simple or complex configuration to the window, allowing you to embody even the most non -standard idea of \u200b\u200bdesigners and architects into reality.

 

Design

The inside of the plastic case of the profile is separated by longitudinal partitions, in turn, they form cavities (air chambers). The minimum number of cameras in profile 3, maximum 8. The number of cameras determines the degree of thermal insulation and sound absorption of the window, the more air cavities, the higher these indicators. It should be noted right away that 3 and 5 chamber profiles are popular.

 

Reinforcement

To give rigidity, the profile is additionally reinforced. The metal frame provides the necessary strength of the structure and reliability during the operation of the window. Galled steel is used to reinforce the profile, so it is not deformed for temperature differences or other environmental influences.

• The Mr. Front type of reinforcement. Metal insert is installed along two walls;
• P-shaped type of reinforcement, where the metal enhances three walls;
• The closed type of reinforcement. Metal insert is located along four walls.

For window structures that have double-glazed windows up to 1900 mm in height, a P-shaped reinforced profile is suitable. However, for plastic windows of large dimensions, for example, for a loggia or balcony, a profile with closed reinforcement is needed.

 

Profile class

 

The thickness of the walls of the profile determines its belonging to a particular class:

• Class A of the thickness of the profile walls should be at least 3 mm;
• Class B profile, where the wall thickness is from 2.5 mm;
• Class with irregular wall thickness.

As a result, the width of the profile of plastic windows directly depends on its class. The higher it is, the accordingly the profile is wider.

What to pay attention to when choosing a plastic profile with a double -glazed window

 

In order to determine what the thickness of the profile is necessary, you should have basic knowledge about the double -glazed window, because up to 70% of thermal losses occurs through it.

This transparent element consists of 2 or more glasses, which are hermetically connected to the frame. Between them, a camera (air gap) is formed, filled with discharged air or inert gas, such as Argon or Crypton. This kind of content is used in the production of energy -saving double -glazed windows.

A single -chamber double -glazed window is a design of 2 glasses of 4 mm and an air gap of 16 mm, in an abbreviated form is indicated - 4-16-4. Thus, its mounting width is 24 mm. The design is 36 mm from a two-chamber double-glazed window, which consists of 3 glasses of 4 mm and 2 layers of 10 mm-4-10-4-10-4.

Therefore, the corresponding profile is selected for the necessary double -glazed window. For example, the optimal solution for a regular apartment or house will be a 5-chamber profile with a 70 mm mounting width and 30 mm two-chamber double-glazed window, where a heat-reflective coating should be applied to one glass.

If the windows overlook the north side and the road loaded with cars runs nearby, then in this case the following option is suitable: a 5-chamber profile with a depth of 86 mm, complemented by a 32 mm double-glazed window with a protective soundproof film.

When the balcony (loggia) is combined with an adjacent room or it is planned to make a small cabinet (rest room) from it, then the profile should be 5-chamber with a 86 mm installation depth, and the double-glazed window, two-chamber with a width of at least 40 mm.

For simple insulation of the balcony, 60 mm 3-chamber profile and 30 mm single-chamber double-glazed window is suitable.

But it is not enough just to choose the optimal PVC profile and double-glazed window. It is equally important to entrust the installation of the finished window to professionals. Otherwise, no matter how expensive the design is, poor -quality installation cancel all its high characteristics.
