First of all, for a single-layer ceiling, the hardness is higher and smoother. The effect of gypsum board double ceiling is naturally much better than that of single ceiling, but compared with the low height of living room, single ceiling design is enough.
If the story is high, it is recommended to do gypsum board double ceiling design. Two-layer plasterboard can also have the modeling effect of plaster line, but visually speaking, wider and straighter line sense can not only play a decorative role, but also stretch the height of the whole space.
The rendering of gypsum board double ceiling is really beautiful compared with the living room without gypsum board ceiling. In the design of gypsum board double ceiling, attention should be paid to the installation position of lamps, which can produce a lighting effect of mutual reflection of point light, line light and surface light, adding a lot of color to the room.

Matters needing attention in the construction of double-layer gypsum board ceiling
1. Gypsum products are afraid of water and should not be stored in the open air. Waterproof and moisture-proof measures should be taken. When transporting and installing decorative gypsum board, handle it with care (it is advisable to transport it in containers) and pay attention to cleaning. If the gypsum board is polluted, it needs to be painted with white or other required colors or paints once after installation.
2. Before installation, the model, size, founder, thickness and surface finish shall be comprehensively inspected. Do not meet the requirements should be timely maintenance and replacement. In order to prevent the structural displacement of gypsum board, a certain gap should be left between the boards during installation.
3. The problem of decorative gypsum board ceiling is large deformation. The main reason is that the humidity in the space does not disperse and the ventilation problem has not been solved. Therefore, decorative gypsum board should be placed in a ventilated and dry room to prevent deformation due to moisture.
4. When installing double-layer gypsum board, the joints between the surface board and the base board should be staggered, and no joints are allowed on the same keel. Docking of gypsum board shall be handled according to product requirements.
Gypsum board and keel should be fixed from the middle of a board to the four sides of the board, and multi-point simultaneous operation is not allowed. The embedding depth of the nail should be that the surface of the screw head is slightly embedded in the pole face to avoid damaging the paper surface. Pinholes shall be derusted and leveled with gypsum putty.
