Q: 75 series of light steel keel wall double-sided double-layer 12 thick plaster board filled with sound insulation noise can reach the number of decibels: Theoretically, the main factors influencing the sound insulation of the gypsum board wall are as follows: 1) the law of quality: there is a common law for the insulation of the partition, that is, the heavier the material (the greater the surface density) the better the sound insulation. For a single layer of dense uniform wall, surface density for each doubled, the sound insulation in the theoretical increase of 6dB, this law is the law of quality. For the double layer of gypsum board wall, the law of quality plays an important role, that is, to increase the number of layers or thickness of the board can be improved sound insulation. As the keel double wall system sound vibration form is very complex, so the embodiment of the law of quality than the simple single-wall complex. 2) Resonant frequency: any partition wall there is an inherent resonance frequency, when the sound wave frequency and wall resonance frequency, the wall as a whole resonate, the frequency of the sound insulation will be greatly reduced.

Q: What is the decoration of the wall? Lightweight bricks Or light steel keel frame?: Decorate the wood keel can be, and then use the integrated wall covered up on it. The other keels are too much trouble and time.

Q: Light steel keel wall waterproof: Used to resist external UV radiation, natural aging and chemical corrosion, effectively extend the coating use

Q: Home improvement in the partition: Lightweight brick wall; a brick made of foam cement material, can replace part of the brick wall, reduce the building load, but the high water absorption. Its structure, sound insulation with the red brick wall is almost the same for the indoor simple wall;

Q: Light steel keel with what screws fixed gypsum board: 2.5cm self-tapping screw! Do not matter where you can use nails. In foreign countries, taking into account the factors of the earthquake, heaven and earth keel and vertical keel can not be nailed.

Q: Can the gypsum board be painted on the wall: If the light can be linked to the screw with a self-tapping screw, hanging 2-3 kg should be no problem

Q: Has installed a wooden floor, you can do in the above light steel keel wall?: Do of course But I suggest do not do it! You do not want to move the floor, you put the floor cut off the partition of the piece. Directly to the disadvantages: 1: wooden floor flexible, partition instability. 2: you are not bad when the wall and the floor shut. 3: sound insulation is certainly worse

Q: Wood keel can be used to ceiling, can be used to do the wall? Light steel keel can be used in what place?: Many temporary buildings will use wood keel to do with the wall, light steel keel more for long-term construction

Q: Light steel keel partition wall how to get, and how to purchase materials and tools, I now empty-handed, the best comprehensive ~!: I think if you are not engaged in the decoration industry, then still find a carpenter to help you do something better, because the production of light steel keel wall, after all, also need some technical and experience Moreover, you just to do so a little Wall, it is necessary to buy so many tools, this should be unacceptable. In particular, the partition is also required to have a vertical degree, you have never come into contact with this kind of thing, then I think you are doing bad.

Q: Light steel keel wall cheap or cheap red brick: Now the sand is soaring, if the area is large, short-term is certainly selected light steel keel, if it is their own long-term use, it is still a brick, expensive on your point!
