How to check whether the wooden door is soundproof?
The following three testing methods are recommended testing methods for ordinary consumers, which are short, flat and fast testing methods summarized according to 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. Therefore, high-density sound insulation is relatively good, and molded doors are relatively light. This is the source of poor sound insulation of molded doors. 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 door surface laminate
The thicker the surface layer, the better the sound insulation effect. Generally, the surface layer of wooden doors should be 8mm thick. The thickness of the surface layer and the flatness will be better, but the cost will increase. But: the iron sheet of the iron plate fireproof 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 deformed wooden door is not soundproof, it will leak air.
There is also a slightly more professional, the quality of the expansion glue between the door cover and the wall, if this is not good, it will also seriously affect the sound insulation.
Note: In fact, the sound insulation of the door and window industry has a national level like fire doors, and is not defined by a single item. The concept of "sound insulation" and "sound absorption". The principle of sound insulation depends on the quality or the density of the material (when the overall weight of the iron plate per unit area is less than that of the wooden door, its sound insulation is not as good as the wooden door), and the sound absorption depends on the fine surface area and uneven surface of the material Space (rock wool, mineral wool, and foam are all sound-absorbing materials, not sound-insulating materials)
