As people's quality of life improves, more and more individuals are turning their attention to sound insulation. This raises the question: what is the national standard for the sound insulation of doors and windows? Let's take a closer look.
I. What is the national standard for the sound insulation of doors and windows?
The sound insulation level is between 22 decibels and 25 decibels. In terms of materials, solid wooden doors have better sound insulation than paint-free doors. The main reason solid wooden doors can achieve such sound insulation is primarily due to the material filling inside the door leaf and the gaps between the door leaf and the door frame. In the normal production of solid wooden doors, wooden blocks are used for filling inside the door leaf, which provides sound insulation better than that of hollow doors. Additionally, advanced precision machines are used to produce solid wooden doors, resulting in smaller gaps that reduce noise and increase sound insulation levels. If the solid wooden door has a solid core, its sound insulation performance can reach over 32 decibels.
II. How are the sound insulation levels of doors and windows classified?
Generally, the sound insulation of doors and windows is divided into five levels. The lowest level has minimal sound insulation performance, with a sound insulation level of 5 decibels. The typical configuration at this stage is an old steel window with single-layer glass. The second level has slight effects, with a sound insulation level of 5 to 10 decibels, typically represented by plastic-steel windows with single-layer glass. The third level has a sound insulation level of 15 to 25 decibels, represented by aluminum alloy windows with double-glazed glass. The fourth level ranges from 25 to 35 decibels, with classic configurations such as broken bridge aluminum windows with double-glazed glass. The fifth level reaches around 35 to 45 decibels, typically using non-metallic composite materials with DEV glass.
III. How to choose sound-insulating solid wooden doors?
1.The materials used in the sound-insulating solid wooden doors play a crucial role. Generally, solid wooden composite doors meet consumer demands, and they use high-density panels on the surface to enhance sound insulation.
2. The internal structure of the door with solid core filling can also significantly reduce sound insulation performance. Therefore, when choosing sound-insulating solid wooden doors, it's important to know what type of material is used for the filling inside the door leaf.
In summary, after reading the above introduction, I believe you have a better understanding of the national standard for the sound insulation of doors and windows. For more related information, please continue to follow our website, as we will present more exciting content in the future.
