The so-called soundproof windows separate the sound with two windows. The gaps in each window are as tight as possible. This method is suitable for all places where there is noise. In addition, double-glazing can also be used because of its sound-insulating effect. It is learned from the market that there are mainly two types of ventilation and sound insulation windows available on the market. One is a mechanical exhaust soundproof window, and the other is a three-track soundproof window. The former is based on the double-track cross-pull window or push-pull window, through the enhancement of glass thickness or the use of double glass, and increase the mechanical ventilation function, to achieve the effect of ventilation and sound insulation, due to the mechanical part, its price is relatively high; The latter uses a three-track window frame, and the upper and lower sashes are designed as a noise cancellation chamber structure, and special ventilation holes are added above the windows to achieve natural ventilation and sound insulation effects. According to the inspection data, the mechanical ventilation window is generally soundproofed by 20-30 dB, and the three-track sound insulation window can still separate noise by 30 dB under natural ventilation. According to experts, the noise performance of the horizontal pull window depends on the degree of closeness between the two windows and the window frame, and the push window is determined by the closeness of the closed window and the frame. Accordingly, although the double-track horizontal pull-type and push-open type soundproof windows are extremely widely used, there are also some design deficiencies. First, the gap between the two glass fans of the double-track horizontal draw window is too large, the cavity below the window fan is not airtight, and the window sash gap of the sound window used in the three-track design is smaller. Secondly, the sliding wheel is easy to wear, and the service life is not too long. After the wear, the window sash cannot be pushed. If the window is opened, the window occupies space. After the hardware is worn out, the doors and windows are easy to fall out. In terms of price, the three-track soundproofing windows are more reasonable and cost-effective. Therefore, consumers should better understand their own needs when choosing soundproof windows, and choose the right products so that they can not only spend more money but also achieve the desired effect. .

In general, windows are classified into two types: fixed and movable. Due to ventilation considerations, the use of fixed windows is generally not recommended, while movable types are subdivided into horizontal and push-open types.
