Nowadays, many homeowners who live in homes after being renovated in their homes feel that their homes are not as quiet as they thought they are. It seems that noise is always transmitted from the glass to the interior. The main reason for this is that they did not buy soundproof windows and caused the windows. Soundproofing is not good, so how to buy a good soundproof window? First, which type of window to choose Brand Shop: Jiaji Doors & Windows The window types include flat open, push pull and fixed type. The soundproof effect of the fixed window is best in terms of soundproof effect, but this type of window is only suitable for places that do not need to be opened but have lighting requirements; Comparing with push-pull windows, the sound-proofing effect of the casement windows is better to push and pull the windows. You can choose the right window type according to your needs. Second, look at the glass material Glass material is divided into ordinary glass, hollow glass, laminated glass, pvb laminated glass and vacuum glass, vacuum glass in these types of glass is the best sound insulation effect, because the vacuum glass is to separate two pieces of glass and evacuated the middle In the air, a vacuum layer is formed between the glass and the sound cannot be transmitted in a vacuum, so no matter what kind of noise is transmitted through the glass, hollow glass and pvb laminated glass can only isolate high frequency or energy. Smaller noise performance can also be achieved. For low frequency or high energy noise, the sound insulation effect is not very good; the insulating glass of the double layer is generally soundproof, but it has high safety and is not easily broken. Third, look at the sealing of the window is good Sealability refers to the degree of sealing of the window, including the sealing of the glass and the frame. After the closure of the window, the seal of the frame and the frame, and the sealing of the window and the wall after installation, together affect the sealing performance of the window. The determination of the degree of sealing of the window is the sealing strip. At present, there are two main types of sealing strips in the market, namely, the wool sealing strip and the rubber sealing strip. Both the wool seal and the rubber seal have their own disadvantages. The wool seal is easy to remove hair in a long time, which greatly reduces the sealing effect. The rubber seals tend to age hard after being exposed to the sun, rain, and rain, and also reduce their sealing effect. Fourth, purchase in the formal home shopping mall, and ask the merchant for invoice Some owners plan to save money in some small shops to buy soundproof windows, but afterwards, if they find that the quality of the windows is a problem, most of the owners are unable to find merchant compensation. If the owners buy in a regular home store, even if the store owner can not find the goods, The store will also solve problems for the owners so that it is easier to maintain their own rights and interests.
