Select soundproof doors and windows, according to the following steps:
First, pick soundproof doors and windows and watch the door.
The soundproof effect of the main doorboard is not soundproofed, and the soundproof effect of the doorboard mainly depends on the filling of the door core.
The moulded and soundproof door core is filled with a paper structure with a honeycomb structure, because the arrangement in a honeycomb form allows a certain material to achieve the largest area and the highest strength, thereby increasing the strength of the door panel. The closed air layer formed by it can play a role in sound insulation. The door made by this method can achieve a sound insulation effect of 29 dB. The inferior door panel is only a few partitions made of cardboard in the hollow core, and the sound insulation effect will be poor.
Second, learn to watch the quality inspection report.
Consumers can request to see the quality inspection report of the relevant national department, including sound insulation effect test report, to understand the performance of the product.
The popular method that can be judged by oneself is: Look through the eyes, the heavy door usually has good sound insulation effect; Listen with the ear, walk to the side of the door, gently knock, feel how the sound effect of the door is, general sound effect is good The sound insulation effect is poor.
Third, the choice of door and window frames. Window frame selection. At present, developers generally use aluminum alloys. However, aluminum alloys are single-cavity, and the walls are relatively easy to penetrate with thin sound. In contrast, the multi-cavities of steel profiles and the walls are thicker than aluminum alloys. The sound is less likely to penetrate through the profile.
Fourth, ingenious selection of noise bars can not be seen. The choice of soundproof strips. Most of the developers choose aluminum alloy window frames with rubber sound insulation strips or wool insulation strips, but the wool insulation strips are prone to hair removal for a long time, and rubber has been used for a long time to get hard and aging through the wind, sun, and rain. Therefore, the soundproofing strip must be both anti-aging and toughness. There is currently an imported soundproof strip on the market. Outside is wrapped in leather material. The sound-absorbing cotton is used inside. In this way, toughness is not maintained and aging is not easy. It is a good guarantee of the sealing of the leaky point of the window frame.
