Anonymous users2024-01-24When the building structure of the room is not very dry, the use of double-layer gypsum board ceiling is to consider enhancing the crack resistance and moisture resistance of the ceiling. In addition, when using wooden keel ceilings other than light steel keels, in order to avoid cracking caused by the moisture of wooden keels, double-layer gypsum board ceilings are also used.
Theoretically, double-layer gypsum board is considered to enhance the crack resistance and moisture resistance of the ceiling. For double-layer gypsum board construction, it is necessary to be coated with polyethylene emulsion to make the double-layer gypsum board really work. When the overall structure of the ceiling is twisted and deformed, it will improve the strength to prevent cracking.
The final decoration effect of adding a layer of gypsum board is the same as that of a single layer of gypsum board, and another factor of whether the top surface is cracked is affected by processes such as surface latex paint. As for moisture resistance, there is a big gap between single layer and double layer, and moisture enters the gypsum board inside the ceiling to absorb most of the water vapor, and then slowly volatilize, without affecting the effect of the surface coating.
Actually, it's all the same. It's just called differently. The South likes to call it an aluminum gusset. The north likes to call it an integrated ceiling. Aluminum gusset and integrated ceiling are collectively referred to. Others are just names that are divided according to different processing techniques.

The integrated ceiling is mostly used in the place of moisture and wind and sun, with many styles, bright colors and beautiful appearance, the aluminum material of the integrated ceiling can be maintained for a long time without aging, and there are many people who use it as a hall ceiling, but the ordinary ceiling is mostly gypsum board, which is not durable for moisture and wind and sun, and is easy to age.

There is a fundamental difference between the two.
Solid wood is made from wood materials, which belong to nature, not synthetic. Pine is a solid wood, the type of wood is different, its density is relatively small, a little soft, if the older pine is a good material, it is also very common in modern furniture. >>>More
