Sound insulation refers to sound waves in the air when the general use of a variety of energy-absorbing materials consume the energy of sound waves so that sound energy in the transmission route is blocked and can not pass directly measures, this measure is called sound insulation. When staying in a commercial house, the sounds upstairs are often annoying to us. To deal with the soundproofing of ceilings is the practice of most of the current owners. What about the ceiling insulation ? What are the ceiling insulation materials? Everyone should not be very clear. The following will tell everyone. How to deal with the ceiling sound insulation and what materials.
How to deal with ceiling noise:
First, upstairs processing methods:
Please upstairs occupants to lay a 6mm high-density soundproof blanket (can be completely resolved, but whether the residents are willing, this is also the art of communication)
Second, the downstairs ceiling treatment method:
1. The first floor: the laying of fireproof soundproof felt for the high proportion of 1mm weight 3.5 kg Sound insulation for the STC25dBA, 2mm weight 7 kg soundproof for the STC31dBA.
2. Second floor: nails frame 5cm above the floor
3. The third layer: fire-resistant sound-absorbing cotton 25mm must be back adhesive, through the adhesive layer to reduce the conduction sound, directly laying the remaining layer of residual air in the center as a reflection to increase the sound insulation capacity of about 8 ~ 10dBA.
4. The fourth floor: gypsum board 15mm
5. Fifth floor: nailed calcium silicate board 6mm.
The above decoration can improve 2/3 noise and the living comfort of the family.
What are the ceiling insulation materials:
Soundproof mats, thick curtains, sound-absorbing cotton, wallpaper, plastic window frames, sound-insulating glass, imported sealing strips, etc.
The soundproof felt is made of odorless EPDM rubber and dozens of organic minerals in a certain proportion. The product is black, environmentally friendly and has no odor. It is a good soundproof material for low frequency and high frequency sound, which can effectively inhibit various Vibration transmission, the thickness of the material is 1mm, 2mm, 3mm range, measured by the State Building Materials Agency, weighted noise reduction Rw were 23dB, 27dB, 30dB, the flexibility of the material is also very good, you can easily bend, arbitrary ribbon cutting, Construction is very convenient and fireproof soundproof material.
Soundproof felt has the following advantages:
1. Lightweight and thin material;
2. Soft, high tensile strength;
3. Environmental protection, does not cause pollution to the environment;
4. Inhibit the propagation of low-frequency sound waves; excellent flame retardant performance;
5. Convenient construction.
Sound insulation in other areas:
For wall insulation. There is a definite criterion that the more real the wall, the more void the interior, and the thicker the wall, the better the sound insulation of the wall. This is beyond doubt. Therefore, do not damage the wall structure during the renovation to prevent gaps. In addition, you can add some wall sound insulation materials, such as some polyester fiber, soundproofing effect is also good, but must be based on the recommendations of the master decoration, so as not to add too thick or too thin and so on.
Top with floor soundproofing. Most of the noise on the floor will not be transmitted, most of them are trampled on the floor by the sound, so you can use carpets or silencing floors; important is the sound from the ceiling, where the sound is mostly upstairs, roof decoration Mostly ceiling or solid wall structure, you can also add a layer of sound insulation material, according to the proposal of the master decoration or silence through the physical structure.
Window silencer. Windows is a major source of noise. In fact, it is very important to consider when decorating. On the one hand, it is possible to use steel or glass steel window frames with better sealing properties. This type of window frame sounds good if the windows are facing too much noise. Double glass is also an option. In fact, you can think of all kinds of needs before you renovate and take precautions when buying materials.
The silence of the door and the silence of the pipes in the house. The silence of the doors and the silence of the pipes are to prevent outside noise from reaching the house, but the doors should keep the noise out, but the pipes must pass through the house. Therefore, the door must have a good sound-absorbing effect and a good texture. In dealing with pipeline noise, sound insulation material is generally used to wrap pipelines. There are many such materials in the market, but attention should be paid to pollution and real effects.
Editor's summary: The above is the industry person who exposed the sound board has a coup to start with the door and window to start the relevant introduction, hoping to help meet the needs of the friends!
