When you are ready to install a soundproof window and feel unsure how to do it, you are advised to do the following:

　　1. Ask the manufacturer for the sound insulation test report of qualified units. Knowing the sound insulation of doors and Windows, according to the economic situation and actual needs, the higher the sound insulation, the higher the price of the soundproof window, but not less than 30dB. If you are serious environmental noise pollution or higher to indoor environment requirement, you need to pay attention to the low frequency of door window sound insulation as well as the lowest noise frequency of the sound insulation, because of the traffic noise energy is concentrated in low frequency, doors and Windows low-frequency acoustic performance is the weakest link, it is bound to cause low frequency sound leakage, ultimately affect the sound insulation effect.

　　2, sound insulation window than ordinary Windows is different from material selection to process, high sound insulation of sound insulation window glass, sealing materials, used in the profile are after repeated experiments and testing to finalize the design, manufacturers should have in the production of sound insulation window technology and engineering performance, when it is necessary to visit each other's engineering sample.

　　3, in order to make your living environment through the replacement of sound insulation window have obvious effect, should ask the manufacturer of your living environment noise testing, although are roads but different grade, urban and suburban ChengJin road traffic noise are very different.
