At present, after the decoration of the new house, the effect of soundproof windows is not very good, and there is always noise sneaking in; the main reason for this situation is that the owner did not choose soundproof windows, resulting in poor sound insulation of the windows. How to choose good soundproof windows?
1. Which type of windows to choose
Window types include casement, push-pull and fixed. In terms of sound insulation effect, fixed windows have the best sound insulation effect, but this kind of window is only suitable for places that do not need to be opened but have lighting requirements; Compared with sliding windows, the sound insulation effect of casement windows is better than that of sliding windows. You can choose the appropriate window type according to your needs.
2. Look at the glass material
Glass materials are divided into ordinary glass, insulating glass, double-layer insulating glass, pvb laminated glass and vacuum glass. Among these types of glass, vacuum glass has the best sound insulation effect, because vacuum glass separates two pieces of glass and evacuates the middle. The air, the vacuum layer is formed between the glass, and the principle that sound cannot propagate in a vacuum is used to insulate the sound, so no matter what kind of noise it is, it cannot pass through the glass into the house; insulating glass and pvb laminated glass can only isolate high frequency or energy Smaller noise performance is okay, but for low-frequency or high-energy noise, the sound insulation effect is not very good; the sound insulation effect of double-layer insulating glass is average, but it is very safe and not easy to break.
3. Check whether the sealing of the window is good
Airtightness refers to the sealing degree of the window, including the sealing of the glass and the frame. The seal between the frame and the frame after the window is closed, and the seal between the window and the wall after installation, together affect the sealing performance of the window. And it is the sealing strip that determines the sealing degree of the window. At present, there are two main types of sealing strips on the market, one is wool sealing strip, and the other is rubber sealing strip. The wool sealing strip and the rubber sealing strip have their own disadvantages. The wool sealing strip is easy to lose hair after a long time, which greatly reduces the sealing effect. The rubber sealing strip is easy to harden and age after being exposed to wind, sun and rain, which also reduces its sealing effect.
4. Buy in regular home shopping malls, with contract guarantee
Some owners try to save money and buy soundproof windows in some small shops, but if they find that there is a problem with the quality of the windows afterwards, most of the owners will not be able to find compensation from the merchant. It will also solve problems for the owners, making it easier to protect their own rights and interests.
