What aspects should you pay attention to when buying soundproof Windows?

First, choose which type of window

Window types include flat, push-pull and fixed, from the sound insulation effect is good or bad, fixed window sound insulation effect is better, but this window is only suitable for do not need to open but there is a need for lighting; Compared with the open and push-pull Windows, the sound insulation effect of the casement Windows is better than that of the push-pull Windows, and the appropriate window type can be selected according to your own needs.

Second, look at the glass material

The glass material is divided into ordinary glass, insulating glass, laminated insulating glass, pvb laminated glass and vacuum glass. The sound insulation effect of vacuum glass in these glasses is better, because vacuum glass is separated by two pieces of glass, and the air in the middle is evacuated, and the vacuum layer is formed between the glass. The sound can not be transmitted in vacuum. So no matter what kind of noise can be transmitted through the glass into the house; Insulating glass and pvb laminated glass can only isolate high frequency or small energy noise performance is OK, low frequency or large energy noise, the sound insulation effect is not very good; The sound insulation effect of laminated insulating glass is general, but the safety is high and it is not easy to break.

Three, look at the tightness of the window is good

Tightness refers to the degree of tightness of the window, including the sealing of the glass and the border. The sealing of the frame and frame after closing the window, and the sealing of the window and wall after installation, they jointly affect the sealing performance of the window. The sealing degree of the window is determined by the seal, there are two main types of seals on the market at present, one is wool seal, the other is rubber seal. The wool seal and the rubber seal have their own shortcomings, and the wool seal is easy to remove hair after a long time, which greatly reduces the sealing effect. The rubber seal is easy to harden and age after wind, sun and rain, which also reduces its sealing effect.

4. Purchase in regular home shopping malls, with contract protection

Some owners plan to save money in some shops to buy soundproof Windows, but later if the quality of the window is found to be a problem, the owners can not find business compensation, if the owners in the regular company to buy, even if the shop to buy things can not find, the store will solve the problem for the owners, so it is easier to protect their rights and interests.
