PVC windows with double glazing are single glazed windows with double glazing. This is the smallest possible size of a glass unit, but there is air inside the window, or the so-called insulating layer, which is able to keep the heat inside the room and it will go less on the street than with the installed classical wooden systems.
Why such an interesting name? All because of the fact that in the whole system one compartment is filled with air.

What are the advantages of this design?
Double insulation. The main advantage of such window systems is increased thermal insulation qualities. Double glazing as much as possible conserve heat, do not allow any air leaks to the street. In cold climatic zones, such windows are in great demand, because they help to save on room heating and save heat. In hot weather, such systems let in much less warm air from the outside, so the house will be easier to keep cool. Bright daylight will illuminate the room, but the heat from the street will not affect you. This design feature allows you to reduce the cost of paying bills for electricity. I see the double glazed windows in Melbourne, Victoria, when I traveling at the Australia. I always proud this country. Most people and citizens, which are living here use this system for their houses.
Reliability and safety of plastic windows with double glazing. Compared with standard double glazing, double glazing is a safer and more reliable option. Single glazing can break down much easier and faster, but in order to get inside a double glazed room, it is necessary to make considerable efforts. Despite the fact that opening and closing double-glazed windows is easy and convenient, it is extremely difficult to break them, which often de-motivates robbers.
Condensation. In the cold season, condensation can often form on the windows. Water droplets form on the warm side, and as the temperature drops, they freeze quickly, turning into frost. This not only damages the appearance of the windows, but also does not allow natural light to penetrate inside the room. In this case, the house becomes more gloomy and darker. Thus, you will also have to increase your heating costs, because the heat will linger slightly inside. Double glazing helps to save heat several times better and has an increased thermal barrier, which reduces condensation several times.
Noise isolation. Double glazing does not allow extraneous noise from the street to enter the room. This is extremely convenient if your windows overlook a carriageway with heavy traffic or if your home is close to child care facilities, where it is constantly noisy.
