The sound insulation indicator is a very professional number. It is not too big for the merchants to say, so it is very practical to learn a way to check the sound insulation of the wooden door. The following small series will tell you how to detect whether the sound insulation door is soundproof.
The following three detection methods are recommended detection methods for ordinary consumers, and are short and fast detection methods based on the characteristics of wooden doors on the market.
1. Look at the weight. The formula of sound insulation is directly related to the density of the material, so the sound insulation with high density is relatively good, and the molded door is relatively light, which is the source of poor sound insulation of the molded door. But note: the soundproof cotton in the middle of the flat hollow door will be more soundproof than the solid wood door.
2. Look at the thickness of the wooden facade laminate. The thicker the surface layer, the better the sound insulation effect. The general laminate of the wooden door should be 8mm thick. The thickness of the surface layer is also good, but the cost is increased. However: the iron surface of the iron plate fire door is 3mm thick, and the sound insulation effect is also good.
3. Look at the flatness of the wooden door. The flatter the wooden door, the better the combination with the door cover, regardless of the structure. As long as the deformation of the wooden door is not soundproof, the air leakage also leaks.
4, there is a slightly more professional, the quality of the expansion rubber between the door cover and the wall, this is not good, it will seriously affect the sound insulation.
