The windows of plastic in the house free from many problems. With them warm and cozy. Wash them easily. They serve long - years to 40 years old. And if you take the cost, then wooden with double-glazed windows, more than two times. The profile is the main part in the window, so you need to choose it carefully.

Design

The main part of the plastic window - PVC profile. The basis of this material:

• kitchen salt;
• oil;
• gas.

In addition there are additives that increase the quality of plastic, in the form:

• stabilizers;
• modifiers;
• fillers.

Profile for PVC plastic window is obtained by punching a soft initial mixture through special shaping mold with desired geometry.

Very important is the comparison plastic window profiles, like structure as a whole, a coefficient expressing the relationship between the temperatures inside and outside the window on a plane and heat flux, which it passes. Inversely proportional to the ratio: ratio growing - heat losses are reduced. Measurement unit: m2 ° C / W.

key feature

Products from different companies are distinguished by the mounting width of the profile of plastic windows, which is the main profile parameter. Most Popular Suggestions:

• standard or classic - 5.8 cm;
• added - 0.7 cm;
• increased - 0.9 cm.

What thickness profile?

Designs are different not only width, but also the thickness of the profile of plastic windows. So for example: if you take GOST 30673-99 standard, then it puts forward the following requirements:

1. Class A:

• on the outer wall - 3.0 mm;
• internal - 2.5 mm.

2. Class in:

• 2.5 mm, 2.0 mm, respectively.

3. Class C:

• and the outer, and the internal wall thickness is not normalized.

And in accordance with RAL standard (Germany), the outer wall should be a thickness of 3.0 mm, and the internal 2.5 mm. Admission is 0.2 mm in the other side. The same requirements and the European Industrial Standard for Class A.

PVC profile stiffness for plastic window

The window must withstand loads:

• static;
• Dynamic.

Since polyvinyl chloride, which is used for the manufacture of a profile by itself plastic, then a reinforcing profile of a thickness is provided with a thickness of a thickness of no less than 1.5 mm in the central chamber. For this profile, an anti-corrosion coating is provided. Extremely in the chambers there are ribs. The appointment of the reinforcing profile also is that imposses are recorded with it.

What profile plastic windows is better?

Selecting an acceptable profile option for plastic windows, you should explore that manufacturers offer. Consider several types of popularity:

Profile kve

Germany and Russia manufacturers. Produced in three modifications:

• Expert - price and quality correspond to each other;
• Select - something average;
• The standard - fully complies with European requirements.

This type of profile for the plastic window has its advantages:

• he is durable;
• for him just to care for;
• sound and thermal insulation characteristics are high;
• safe for people;
• withstands a wide range of temperatures;
• combined with different systems.

As a minus, it can be noted that it can harmonize not with each interior, since the color is not snow white. And here is the characteristics in the digits for the KBE standard and KBE expert to determine which one of them is the best profile for plastic windows:

KBE Etalon Kve Expert

• mounting width - 5.8 cm; 70;
• glass thickness - 3.4 cm; 42;
• cameras - 3; 5;
• light opening - 6.4 mm; 0.78.

DekenNight profile (Dekeninck)

Released in Belgium, Concern Deceuninck. Systems:

• Favorite. More modern, the number of cameras is greater. The cost is appropriate;
• Butek - lower reliability. In terms of cost, it can be said that this is an economy class.

Pros:

• high heat conductivity;
• durable;
• safe;
• well protects against noise;
• satisfactory appearance;
• relatively small price.

Minuses:

Butek is not a universal system. Not suitable for everyone.

Rehau profile (Rehau)

Rehau produces German company. Releases profiles in seven modifications.

Positive sides:

• durable, large service life;
• resistant to very low temperatures;
• functional;
• environmental;
• heat and sound insulation are excellent;
• easy to care.;
• excellent combination with other systems.

The sash size is slightly smaller, since the reinforcement chamber has relatively small sizes.

Profile of a century (VEKA)

Manufacturer country - Germany. Basic profile systems:

• Softline;
• EUROLINE.

Different with dimensions of light spaces. VEKA EUROLINE It has more: by 0.6 cm at a non-opening window and 1 cm at the opening.

• Distinctive feature: The profile may have a width of 9.0 cm;
• Characteristics of strength, heat and noise insulating, temperature - high;
• Lose popularity due to a sufficiently large percentage of lead oxide, which is why they cannot be called completely environmentally friendly.

What are the profiles of plastic windows, you now know, but choosing to get acquainted with other information.

What to watch what to ask

The best profile for plastic windows, will not be the key quality of the window, if not considering the following:

• predominant temperature mode;
• where the window will be installed: in the office, houses, in the industrial premises.

Immediately find out which material is based on a plastic structure profile. If this is not galvanized steel - do not buy. Otherwise, after a while you will have to fight the serving, in the holes that moisture is given, rust. And besides this, such criteria are important:

• how many aircases in the window;
• width of the glass
• insulation contours - how many of them;
• quality sound and thermal insulation.

Glass profile classes

Depending on the thickness of the outer wall, they are officially divided into 2 classes:

• A - high quality, the wall is thick;
• B is characterized by lower characteristics.

Vradiatful cameras

The number of aircases in different structures of plastic windows differs. Choosing an acceptable option for the house, you need to know:

• the number of cameras in the double-glazing does not have to correspond to their number in the profile;
• the more cameras in the profile, the more strength, heat and noise insulation. The cost, by the way, is also directly proportional to this indicator;
• the most suitable option: double-glazed windows consisting of 2 chambers inserted into a three-chamber profile.

Glass windows

The chamber in the glass - there is something that is located between the glasses. Double glazing are:

• consisting of 2 glasses - single-chamber;
• from 3, 4 and so on - two, three, four chamber;
• selected depending on the prevailing temperature modes in the area where you live;
• on the insulating features of the glass equipment also affect the thickness of the glass.

Glasses can be:

• energy saving;
• sunscreen;
• laminated;
• shockproof.

Interesting: To find out if you did not slip it instead of a two-chamber single-chamber glass, use the burning match: close it to the glass and count the images. So many images, how many cameras.

Comfort in the house and fittings

The window in the house will not be good without high-quality fittings, which means it will not provide sufficient comfort in the house. The list of accessories includes such mechanisms:

• devices for fraamug;
• locks;
• loops;
• swivel knobs;
• the mechanism of rotary-folding;
• tsazfy and more.

The accessories of the window must match the shared style of the room, so it is produced in different colors. And most importantly: do not save on accessories, otherwise even the most high-quality profile for plastic windows will not justify your hopes.
