First, the ordinary doors and windows sound effects
1, Steel doors and windows
At present, there are various styles of steel doors and windows, in addition to the traditional inside and outside the flat open, push and pull and folding type, there are open on the hanging windows and doors, sliding doors and windows hanging, sliding doors and windows. In terms of color, the market common steel doors and windows mostly white, because white or gray PVC profiles weather resistance and light stability, but also appeared in color profiles, decorative design more freedom to play space, more personalized. Although the price is higher, but the market potential is still huge.
Plastic doors and windows of the sealing performance is good, to ensure the sound insulation effect. But also bring weaknesses in air circulation. Manufacturers for this situation, the development of the windows in the use of the ventilation, not affect the sound insulation, but also to ensure the exchange of indoor and outdoor air. The ventilator can be installed between the window and the window line, not the place. Prices range from $ 200 to $ 90, depending on quality and specifications. If you want to switch the timing window, you can choose the market to launch a new automatic timer switch. Its price is about 2000 yuan. In the United States and other large building materials center can be found.
At present the market price of steel doors and windows mixed. Plastic steel windows as long as three or two hundred square meters per square meter, imported products up to more than 200 US dollars. Plastic steel door price difference is also great, ranging from a few hundred dollars to three thousand dollars.
2, Aluminum window
New aluminum doors and windows Most people think that aluminum doors and windows of the sound insulation is not good, but in fact the new aluminum doors and windows in the sound insulation performance has made a greater improvement. The sound insulation of the window is mainly about 80% of the area of the glass insulation effect, followed by the sealing performance of doors and windows. Some aluminum doors and windows on the market according to the sound wave resonance transmission principle and lotus cooperation, using a different combination of glass structure, enhanced sound insulation. In the air-tight structure of the doors and windows, high-quality plastic, plastic sealing parts of the use, but also to a large extent to solve the aluminum doors and windows sealing performance problems.
Aluminum doors and windows of the strong coloring ability, through a special process, you can make imitation wood and imitation granite and other effects, so that the appearance of doors and windows more beautiful colors, suitable for people with different decorative requirements.
Second, the noise doors and windows to buy
1, Window frame
Developers generally use aluminum alloy, but the aluminum alloy is a relatively thin wall of a single cavity, the sound easily penetrate, and plastic profiles of the multi-cavity, wall thicker than the aluminum alloy, the sound is not easy to penetrate.
2, Cound insulation
Most of the developers use aluminum alloy window frame with rubber sound insulation strips or wool insulation, but the fabric insulation for a long time easy to hair removal, and rubber with a long time after the sun and rain the capacity of hardening aging, so the noise It is necessary to prevent aging and maintain toughness. At present there is an imported sound insulation on the market, the cortex material is wrapped outside, which is the choice of sound-absorbing cotton, so that is to maintain toughness is not easy to aging, a good guarantee of the window frame leakage point of the seal.
3, The most important sound insulation glass
Now in the market are mainly insulating glass, laminated glass, there is a vacuum glass. The first two prices from more than one hundred to seven thousand eight hundred thousand have. One or two hundred glasses I will not say, are street stalls sound effects no guarantee. Professional do sound insulation doors and windows of the company, mostly laminated glass and insulating glass. This kind of glass effect can also be but against the cart or faster when the low-frequency noise produced by the effect is not ideal.
Vacuum glass can not use the principle of vacuum transmission can be installed after the noise reduction of 30-40 dB. Such as more than 20 floors and no trains nearby, large trailers, etc. can be considered to choose hollow glass or laminated glass; low floor and near the road or near the viaduct and near the low-frequency noise source, then it is necessary to consider the use of vacuum glass , So as to completely solve the noise problem.
4, After the installation of the border around the seal
Do the sound of the window when the window frame around the number will leave some small gap, so after installation must use glass glue around the window stick well. Surrounded by the seal seems simple, but still find a professional master to do to be very perfect.
Of course, when the choice of sound insulation doors and windows must pay attention to small skills, such as furniture is best to use some wooden, wooden furniture generally have a certain sound absorption function; shop in the interior shop some carpets, especially thick carpet sound effects Very strong; can be padded under the foot of the rubber pad, so that you can reduce the resonance caused by the past vehicles, which is a good way to sound insulation; the cabinet on the noise facing the wall, so that the noise generated by the wall into the room It is necessary to go through the cabinet.
Of course, for the newly renovated family can consider the floor overhead. This can effectively isolate the ground from the wall resonance. At the same time hanging on the wall what some decoration, so that the sound can be reflected in this different direction, the echo will be less.
