How to reduce the indoor noise, we have to start from the source, which is why the double-layer glass in our home is not soundproof well. The following are mainly studies on plastic steel windows and aluminium windows.
Double-layer glass window "cut corners"
The so-called double-layer glass-plastic-steel windows in commercial housing are commonly used to cut corners. As long as all the hinges with switches are not available, because all the seals are simple, regardless of the joints between windows and walls, the junction of plastic-steel windows, sliding window the combination of window edge and window frame, and the combination of casement window and window frame. The accessories (rubber strip and dust brush) of these parts are relatively low-grade, which will be explained to you in detail.
The standard of Windows is basically Common. Obviously, the sound insulation effect in the lower right corner is better than other ones above, although you may not feel it.
As for why this happens, then everyone will follow the thinking of the editor to study why this happens.
Window construction instance
considering that the main system of plastic-steel windows is similar to that of aluminium windows, the aluminum alloy used is used as an example. As shown in the figure, the part marked with the red line is the part that blocks the gap between the two window pages (* 1).
The red circle is the structure between the upper and lower windows and the window frame, and it can be seen that there is a gap (* 2).
Wronged glass manufacturer
The misunderstanding of the public: you may think that double-layer glass is not good, and it is not soundproof and vibration-proof at all, but in fact, there is basically no trick to that piece of Casement glass, glass is usually customized directly from the glass factory (if the window factory produces glass, it will not consider cutting corners). The full size is completely 5 10 5 vacuum double-layer glass, which only needs to be installed at the factory, the window glass is sealed with black sealant, which is really not bad, and the cat is not at this point at all.
Do you know where the money is saved? It is not saved on the frame material and glass of plastic steel window, but on hardware, parts and sealant.
The cat on rubber gasket
There are windows around you. You can have a good look. Think about whether the small brush-type one can be insulated from wind or not. Is the gray tape better. Just like when I get a pressure cooker, the pressure of rubber gasket is different from that of rubber gasket. Besides, if the seal of the refrigerator is broken, the refrigerator will not be cooled. The nature is similar. And this is the most common place where money is stuck in construction.
Problems in construction
For the construction progress, builders directly use expansion bolts to fix the window on the wall, omitting the Foundation and other parts, and there will be some problems in the spraying of expansion glue, such as the inferior ones bought by expansion glue, too little colloidal material is sprayed out, too much compressed gas causes the filling percentage to be too low, for example, the expansion glue is not full, and the most common is that the window is small, after the window is installed, the gap between the window and the window hole is too large, and it is not easy to seal with expansion glue.
Another situation is that there is no reserved sealant position on the cast-in-place window. It is directly made and the window is tightly stitched. There is no place to expand the glue, so the sealing is poor, so it leaks, there is no sound insulation.
Five gold and plastic steel profiles with deep water
In addition, hardware is also important. For example, a set of national standard hardware (including rotating clip male and female connector, expansion screw, foot, iron foot, air hook, screw, etc.) may be five times that of non-national standard, moreover, when installing, I cut down on work and materials again. If a window needs 10 expansion screws, six of them cannot fall off.
Then there is a plastic steel profile with a big head. For example, if it is required to be 3mm thick, I will have a 2.4 one. If the steel wire is steel lining, I will give you a 0.6 one. This is also the price, so I want to make money here, it's so simple.
How to improve the sound insulation effect of Windows?
So much has been said before, now we can prescribe the right medicine, if you feel that there is no sound insulation at home, you can change the adhesive strip of thick thread red line in the second picture and use acetone glue to re-glue the junction between the window and the window, in this way, you will find that the noise situation will be greatly improved.
In addition, using a good curtain can also reduce noise, such as velvet.
