In terms of the climatic environment of the south, the sound insulation effect of the window is the main demand of the average family. Then I rely on many years of industry experience to help you choose the soundproof windows you need reasonably.
There is only one road and it is 100 meters awayIn this case, the current market of ordinary broken bridge windows: the workmanship is not too bad, the fan does not leak, it is completely enough, I feel that the ventilation of the window is not enough, it is not as convenient as moving the window, then it is no problem to choose a better quality sliding window. By the way, there are no single-glass windows anymore The starting point is double-glass tempered, 2The road is very close and there are large trucks passing byThen it is best to choose a glass with a window and laminated hollow glass After closing the same as above, test whether there is air leakage, ordinary broken bridge materials are OK. It is not recommended to move the window No matter how good the moving window is, it is basically not the top thing, but the ordinary broken bridge window workmanship and internal auxiliary material configuration problems can not be heard at all, and the sensitive sound should refer to Article 3.
The elevated highway is close and there is a railwayThe workmanship configuration of this ordinary window is not enough, it is necessary to choose a better brand of windows and also to make laminated hollow glass, here I want to focus on why the difference between ordinary brands and good brand windows in this regard: first of all, the workmanship includes splicing, the sealing design of the opening fan, whether the notch of the profile of the glass has a water-retaining adhesive strip, the number of locking points of the hardware and whether the design is scientific, etc. There is also the main material: the same aluminum alloy frame has almost no impact on sound insulation Mainly glass Big brand glass is the real national standard And ordinary brands are glass is generally made of local materials Almost all of them are non-standard thickness, which I have compared The same size of glass Big brands are much heavier than those produced locally, and the thickness of the glass is also an important factor affecting sound insulation. To sum up, there is a gap of 3-5 decibels in sound insulation performance between ordinary brands and big brands with the same configuration, but the difference in labor and equipment conditions for this last bit of effect is very large. For the user, it is the difference between complete sound insulation and vague sound.
Extreme sound insulationIf there is really an extreme requirement for sound insulation, such as on the edge of the airport, or the ultimate sensitivity to sound, then there are only 2 types of windows on the market at present: 1 aluminum-wood (80% of the faceted wood is called aluminum-wood) 2. The frame I just said has little impact on sound insulation, but it is not without The essence of sound is vibration, windows as a medium, the better the shock absorption effect of the main material, the more effective it is naturally for sound insulation, wood and plastic are the best shock absorption effects in the category of windows, as for glass, it is best to have 4 layers, for example: 5 + 114PVB+5+8A+5+8A+5 Laminated with two hollows. There are more layers on the market, but I don't think it's necessary, because any more of them would be more than the sound insulation of the walls.
The above is the selection suggestion for soundproof windows, and the following pictures of some glass are easy for you to distinguish.
