Sound is transmitted through the medium, when the window is opened, the volume outside the window can be clearly felt, that is because the sound enters the room through the air obstructively, and after the window is closed, the noise is significantly reduced. Therefore, doors and windows are the lifeline of home silence, outdoor noise, good soundproof doors and windows.

1. Doors and windows of vacuum insulating glass Some doors and windows have only a thin layer, and some have two layers and three layers, and the middle of the glass is vacuum, and the surrounding area is sealed with glass glue to form a vacuum. This insulating glass increases the thickness of sound wave penetration and the principle of vacuum sound insulation, which can greatly reduce the incoming noise.

2. The use of glass thickness In addition to the way of insulating glass, the thickness of the glass itself is also very important, the sound wave propagation will be reduced differently with the different medium, the thickness of the medium is the value that affects the penetration, and the thicker the glass with the same mass, the lower the penetration of the sound wave.

3. Broken bridge aluminum alloy The price of broken bridge aluminum alloy is higher than that of other aluminum alloy products. Sliding door manufacturers add plastic to the aluminum alloy, using the sound insulation performance of plastic and the principle of sound wave penetration and weakening of different substances, and the aluminum alloy with weak sound insulation is also armed and soundproofed.

4. Sealing strips Aluminum alloy doors and windows generally have sealing strips for sealing treatment, which increases the difficulty of sound penetration, and also provides people living in the bustling city with a quiet and comfortable home.
