Soundproof windows principle, do you know what it is?

Lighting windows can not be completely sealed, the best way to change the window. Sliding windows do not meet the requirements, changed to leg insulation aluminum doors and windows, open the window, glass with 612A6, insulating glass, is the principle of hot water bottle, hollow is a vacuum, slow heat transfer, if possible, you can allow inert gas (argon, etc.) in the hollow area, once and forever rest. Residential exterior window noise has a great impact on the interior, basically by strengthening the exterior window airtightness and replacement of double insulating glass to solve the problem, more peace of mind, less budget.

The air pressure outside crushes the glass, so it's important to recharge the inert gas inside. The thicker the insulating, the better the sound and heat insulation, but the higher the price. Generally speaking, in order to improve the sound insulation performance of windows and doors, should be installed using a double-layer structure, the spacing between the double-layer windows is preferably 20cm-30cm. this can achieve the same sound insulation effect as concrete. When strengthening the soundproof effect of windows, window installation can save the existing window and add another window to achieve noise isolation effect, it is recommended to install ordinary plastic windows or soundproof windows, the effect is very obvious. Window frame material selection. Currently commonly used is aluminum alloy. But aluminum alloy are a single cavity, the wall is relatively thin sound is easy to pass. In contrast, plastic steel has multiple cavities and thicker walls than aluminum alloy. Sound is less likely to penetrate from the steel.

Soundproofing film is a multilayer structure that uses a polyvinyl butadiene vinyl aldehyde (PVB) layer to sandwich the soundproofing resin in the middle, evenly dispersing microparticles of heat-insulating effect. If the window sound insulation effect is not good, in the window glass on this soundproof film can be very good shielding noise, this film does not affect the line of sight and transmission ratio effect, the price is also very low, easy to use, stickers and cell phone stickers nowadays, it is very convenient and quick, but also play the effect of the glass explosion-proof. At present the window frame is generally choose aluminum alloy, but aluminum alloy are single *** with relatively thin, sound very good penetration. But plastic steel is porous, thicker than aluminum alloy, sound insulation effect is also good.

Soundproof glass has hollow glass, vacuum glass, laminated glass, the most commonly used is false glass and vacuum glass. If the floor of the house is above 20 layers, and there is no large vehicles nearby, you can use celluloid glass and insulating glass, sound insulation effect is not bad. Vacuum glass utilizes the principle that a vacuum cannot transmit sound, and for different frequencies of noise, the noise can be reduced by 30 to 40 decibels after installation. If the bottom of the house in the viaduct or nearby low-frequency noise sources, you can consider using composite triple acoustic glass or vacuum glass to completely solve the noise problem.
