Under what circumstances to use double gypsum board ceiling

Answer:

In general, only high-star hotel and high-end hardcover residential will use double ceiling (keel need to use at least the national standard light steel keel), the advantage is high flatness, easy to crack.
Rarely present it! Is generally a layer of. Is it possible to have a layer of gypsum board in order to reduce the height? The But there is not much difference.
When the room building structure is dry is not very good when using double gypsum board ceiling, is to consider the enhanced ceiling of the crack resistance and moisture resistance. In addition, in the use of light steel keel outside the wooden keel ceiling, in order to avoid the wood keel caused by the moisture cracking, but also the use of double gypsum board ceiling. In theory, double gypsum board is considered to enhance the crack resistance and moisture resistance. Double gypsum board construction, to be full of polyethylene emulsion, double gypsum board really play a role. In the ceiling of the overall structure of the distortion, deformation will improve the intensity of anti-cracking. Add a layer of gypsum board and a single layer of gypsum board is the same effect of the final decoration, the other is the top surface cracking is affected by the surface of latex paint and other processes. As for the moisture resistance, single and double layers have a large gap, there are moisture into the ceiling inside the gypsum board will absorb most of the water vapor, and then slowly volatile, does not affect the effect of surface coatings.
Insulation, noise, no money to make a place. Probably these three categories
