In home decoration, most people want to live with the elderly, children or babysitters. In addition, the area of the house is not too large, and the sound insulation effect is particularly critical. However, the sound insulation index is a very professional number. It is not very useful to rely on the businessman. Therefore, it is very practical to learn a little way to check the sound insulation of wooden doors.
The following three detection methods are the recommended detection methods for ordinary consumers, and are short, smooth and fast detection 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, so the sound insulation of the high density is relatively good, and the molded door is relatively light, which is the root cause of the poor sound insulation of the molded door. But note: adding sound insulation cotton in the middle of the flat hollow door will be more sound insulation than the solid wood door.
2. Look at the thickness of the wooden door panel
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 are also better, but the cost will increase. However: the surface layer 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 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 seriously affect the sound insulation.
Note: In fact, the sound insulation of the door and window industry has the same national level as the fire door, rather than a single content definition. 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 door is less than that of the wooden door per unit area, 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 sound absorbing materials not sound insulating materials)
