If it is a villa, it must be made by Cyclobalanopsis glauca. If it is a smaller job, it is recommended to use wooden dragon. Of course, if you are afraid of deformation, use gypsum board. Gypsum board is the cheapest material and can be made in many styles. There are light steel keel gypsum board ceiling and wood keel gypsum board ceiling, which are divided into main ceiling and main ceiling. Usually, the ceiling in the living room is the main ceiling.

When installing, the position must be correct and the connection must be firm. Decorative materials used for ceilings, walls and floors should be nonflammable or flame retardant, and wood materials should be flammable, so they should be treated with fire prevention. General lighting, air conditioning and other electrical pipelines should be laid in the ceiling and operated in strict accordance with the specifications to avoid fire hazards.

If colored stained glass and frosted glass are used as ceilings, they are more and more used in home decoration, but if the materials are not suitable, safety accidents will easily occur. In order to use safety, safety glass should be used in the parts that are easy to be hit, such as the ceiling.

Room wardrobe commonly used plate has the following kinds:

1. Blockboard (commonly known as large core board)

This wardrobe is made of plywood with solid wood core, which has poor vertical bending and compressive strength, but high transverse bending and compressive strength. At present, the plates on the market are mostly solid, glued, double-sided frosted and five-layered, which is one of the most commonly used plates in decoration.

2. Core plate

Particleboard is a kind of artificial board, which is made by cutting all kinds of branches and buds, small diameter wood, fast-growing wood and sawdust into pieces of certain specifications, drying them, mixing them with rubber, hardener and waterproof agent, and pressing them at a certain temperature and pressure. Because its cross section resembles a honeycomb, it is called particleboard.

3. Fiberboard (also called MDF)

Fiberboard is made of plant fiber as the main raw material through thermal grinding, sizing, paving, hot pressing and other processes. Fiberboard has different densities. The density below 450kg/m3 is called low density fiberboard, the density between 450-880kg/m3 is called medium density fiberboard (MDF), and the density above 880kg/m3 is called hard fiberboard (HDF). Density board is mainly used to produce finished furniture, and also used to strengthen wood floors, door panels, partitions and so on.

4. Solid wood finger joint board

Finger joint board, also known as integrated board, integrated board and finger joint board, is a kind of board made of small pieces of solid wood after deep processing like "fingers". Because the interface between plates is serrated, similar to the cross joint of two fingers, it is called finger joint plate. Because the logs are cross-glued, the gluing structure itself has a certain adhesive force, and because there is no need to stick panels up and down, the amount of glue used is extremely small.

5. Multi-layer solid wood board

Multi-layer solid wood board is made of criss-crossing multi-layer plywood as the base material and high-quality solid wood veneer or technical wood as the fabric on the surface, through cold pressing, hot pressing, sanding, curing and other processes. Because the multilayer solid wood board has the characteristics of difficult deformation and good indoor temperature and humidity adjustment performance, the surface solid wood veneer material has the texture and feel of natural solid wood and has stronger selectivity. Therefore, it is favored by consumers.
