For several decades, plastic windows and doors have become widely used in most modern residential, office and industrial facilities. Plastic structures firmly took the place of the main type of partitions from the environment to create windows / doors in the house and apartment.
Along with its popularity, many say that plastic windows have many features and controversial issues. Well, let's understand all the intricacies of these simple and technological mechanisms. Scatter myths about plastic windows.

Myth 1. The best manufacturer of plastic windows - Germany
In part. It is important not in which country do metal profiles and double-glazed windows, but by what technology and on the basis of what materials. And yet, it all depends on the compliance of the manufactured product with international and European standards. Adapted standards for regions with low temperature conditions allow the end user to get plastic windows with a guarantee of operation up to 10-15 years.
Myth 2. Plastic windows - continuous chemistry, which is harmful to humans.
In this case, look around you and name the number of plastic objects that are around you. All of them are harmful, they must be urgently thrown away! The manufacturing technology of the plastic metal profile for the frame and sash itself is protected by quality certificates. They guarantee safety and harmlessness to humans. Chemical emissions as such are simply absent.
Myth 3. Are they perfectly silent?
Not. As you know, sound is characterized by a parameter such as frequency. Roughly speaking, this is the rate of change in air areas: rarefaction and compression. The speed of movement of such areas - this is the frequency. As a result, the high frequencies (very fast fluctuations of the regions) of the sound can’t just “click” on the glass to transfer compression to the camera and further to the room. Therefore, plastic windows perfectly protect against high frequencies (squeak, birds' voices, meow, etc.) and absorb little low-frequency sounds (jackhammer sound, compressor operation, etc.).
Myth 4. The number of cameras and the thickness of the profile - the more the better!
This is one of the main misconceptions. For a double-glazed window, 2-3 cameras are standard (4 + 5/7 + 4). Believe me, this is enough to keep the heat in the room. The thickness of the glass is 4–5 mm. A profile is a bit more complicated: it all depends on the quality of the material from which they are made and the number of partitions (chambers). The standard for the best PVC profile is 4–6 chambers - this makes it more expedient to distribute air flows in the middle and maintain a constant temperature, which affects thermal conductivity.
Myth 5. The use of vacuum in the design
This is more like a marketing move from sellers than truth. Under the generally accepted vacuum understand the area of significant rarefaction of air or its absence. If we created a vacuum of such a level as physical vacuum, then the glass of the package simply crumbled into small parts. But nevertheless, it must be said that the technology for manufacturing a double-glazed window provides for a small vacuum to create a low-pressure region in the middle of the packet. This allows you to keep the glasses in the bag: "pull" them into the camera.
Myth 6. Why do plastic windows “cry”?
Because everything is to blame for the lack of banal airing. For example, we installed a new balcony frame from a metal profile, and the neighbor still has an old one made of wood and 3 mm glass. In the morning we woke up and see that our windows on the balcony were covered with drops of moisture, and the neighbor was doing well. How so? Everything is simple. Plastic windows provided a significant tightness of the balcony, where air could not get from the outside and there was no circulation of air masses. As a result of equalizing the temperature outside and inside the balcony, the moisture difference condensed on the glass.
In order to avoid such situations, it is recommended to ventilate the room 2 times a day for 5-10 minutes.
