If 60000 is not effective, you can try the following method:
1. Stick the window sound insulation film.
When using sound insulation film in buildings, the high-performance intermediate film sandwiched between the film has visible light transmission performance, so it will not block the visible light transmission rate of buildings and keep clear sight. Window sound insulation film is relatively cheap, and the usage is the same as that of mobile phone film.
2. Install windows soundproof seal strip.
Soundproof seal strip, it is only effective for Windows with poor sealing, and the price is also very cheap, but make sure that it is caused by the large gap of Windows without sound insulation, otherwise it is useless to paste it. The sealing strip blocks the gap of the window, which is the same as sound insulation cotton.
3. Add a layer of ordinary plastic steel window.
This method is suitable for outdoor traffic noise is not particularly serious, and if the window sill in the home is relatively wide, a layer of ordinary plastic steel window can be installed inside or outside the original window. Plastic steel window should choose good sealing.
Broken Bridge aluminum materials are sound insulation and heat insulation, so the price is expensive, moreover, because the width of broken bridge aluminum itself is relatively large, glass with large gap in the middle is generally used, which is usually referred to as 5 12 5 or 6 12 6 and other specifications. This kind of sound insulation effect is very good, of course, it depends on whether it is vacuum glass or hollow glass. Vacuum has the best sound insulation effect. Hollow is ordinary and the price is different, so compare your own price and ask the merchant to change it for you.
I spent a lot of money on a window less than 5 square meters, and opened two windows. Other glass is fixed. Can you understand what it looks like? It cost 4500 broken bridge aluminum, double layer doubling tempered glass hollow layer double layer doubling tempered glass, 4 layers of glass, it can not be said to isolate noise, but the noise will definitely not cause trouble, when the bus passed, there was still a little sound. The foreign brands selected for two or lock set yuan were several hundred more expensive. It was cheaper to choose domestic brands. I also went to see colorful brands. I felt that it was just normal, this thing has no technical content, but it is hard to separate it. Broken Bridge aluminum, laminated glass and hollow layer are all put on, and the effect is definitely good.
