Choosing a double-glazed window for installation in a residential apartment of the apartment, it would be desirable that optimal energy saving and noise absorption be ensured. Which glass unit can provide comfortable living conditions? After all, it is almost impossible to visually analyze the possibilities of a plastic window. So, choose the right plastic window.

Opportunities of double-glazed windows for noise protection
The well thought-out and perfect design of plastic windows allows to reduce undesirable stress factors, one of which can be called noise outside the window. Therefore, having installed plastic windows, you can immediately feel that the noise level from the street has significantly decreased.
For reference, modern models of plastic windows can reduce noise to 35-45 dB. Significantly reduce the noise level can be due to the installation of sound-proof or noise-absorbing double-glazed windows. Which glass unit in this case to give preference: single-chamber or double-glazed windows? The answer to the question lies in the technical characteristics of insulating glass.
Characteristics of double-glazed windows on sound insulation
Any double-glazed window occupying a significant area of the window opening has soundproofing properties. For example, the sound insulation of the insulating glass unit 4 (float) is up to 27 dB, and the 4-16-4k (argon) glass packet reaches 36 dB, the sound insulation of the 4M1-15-4M1-15-4M1 glass unit is 37 dB.
The main characteristic of float glass is the directional transmission coefficient. Therefore, the greater the value of this coefficient, the better will be the noise insulation.
It should be noted that double-glazed windows effectively reduce and eliminate low-frequency noise. According to sanitary norms and regulations, noise is acceptable, the level of which does not exceed 45 dB.
Sound insulation, which should provide double-glazed windows, will depend on the presence of several factors, namely:
• thickness of glass
• the quality of the airtightness of the window porch
• the amount of air space between the windows of the package.
The most popular for reducing noise can be called a single-glass unit, which can be installed in almost any room in the apartment. Exceptions are the bedrooms and children's rooms, for which the installation of double-glazed windows is more effective. To make sure the correct choice of the double-glazed window, consult the expert's advice in the video.
glass thickness
An important role in the suppression of noise is played by the thickness of the packet glass. According to the standard, the thickness of the entire insulating glass unit can be in the range from 16 to 46 mm. The thickness of a single glass can be 5-6 mm. Preference is given to the glass with a thickness of 6 mm. Moreover, the thickness of the double-glazed window is not important for noise insulation.
Such parameters are necessary for creating the optimal option for the insulation of the window with double-glazed windows. In certain cases, a single-compartment glass unit made of a higher-quality glass is more efficient than a two-compartment unit of poor quality material.
quality of a tightness of a window porch
The quality of the airtightness of the window porch leads to a reduction in the noise and heat-shielding characteristics of any double-glazed unit.
The infiltration that occurs under the influence of heat and wind pressure can lead to the creation of negative conditions. That's why the manufacturers of plastic windows have thought over the design of the sealing of windows, as well as their interfacing with walls. It is recommended to entrust the inspection of the integrity of the double-glazed window to specialists so that the reasons for the unsatisfactory quality of the airtightness are eliminated even at the stage of installation of the plastic window.
airspace between packages
The quality of heat and noise insulation of the plastic window is affected by the width of the profile, which should be maximum. Recall that the standard profile width is in the range from 58 to 70 mm. Better heat preservation and higher noise insulation characteristics can be achieved by increasing the distance between the panes. When choosing a double-glazed window, it is not unreasonable to pay attention to the quality of the fit density of working (opening) parts and window elements, as well as special profile sealing rubber for sealing.
Ideal option can be called accessories with two modes: "winter" - "summer", as well as a switch that changes the distance between the sash and the frame.
However, the parameter "type of glass", which gives the plastic window specific characteristics, practically does not affect the noise absorption. Special types of glass make it light-transmitting, tinted, reflective, but not noise-reflecting.
Recall that heat-saving or energy-saving plastic windows allow short-wave UV radiation, while not allowing the output outward to long-wave radiation.

Improving noise insulation helps triplex.
Sound insulation of plastic windows - triplex
Triplex is a technological combination of layers of glass and a special layer between layers. The use of triplex glass allows us to provide adequate noise insulation and mechanical safety. Triplex is a three-ply glass, which has an increased destructive load.
A sheet of glass with a deposited plastic film, up to 0.35 mm thick, is placed between two adjacent sheets of glass when manufacturing a triplex. There are three-layer glass of the following types:
• Film
• flood.
The production of a film triplex during factory manufacturing is carried out by gluing together glass layers using a polymer film. The filling type of the triplex is accomplished by joining the sheets using a laminating compound. Regardless of the type of triplex, three-layer glass provides resistance to mechanical scratches and UV exposure, as well as optical transparency.
So, for example, in comparison with the glass type 4m, sound insulation of which is 28 dB, the soundproofing of the triplex with a thickness of 7 mm will be equal to 33 dB.
In addition, to reduce noise from the street, in addition to three-layer glass, you can successfully use an economical option. This is the use of glass with a thickness of 6 mm, but with different distances between the glasses of the package. This decision of the manufacturers of plastic windows was taken to analyze the results and indicators of the restraining force of the PVC window from the noise source from the outside.
The triplex glass triplex with 4 mm thick glass, including the outer glass, will provide more noise absorption than the standard two-chamber package with 6 mm glass. Therefore, soundproofing of plastic windows with the use of a triplex can be considered an optimal option to combat noise.
