3. The ceiling is made of real wood and artificial wood.
Real wood was a very popular ceiling material in the past. with natural beauty But at present, the price of wood is much higher compared to other materials, making the cost and maintenance of this type of ceiling expensive as well. We will not go into depth in the properties of real wood. Because many of you already know that real wood is beautiful. Can do both closed ceiling and slatted ceiling, but the price is increasing every day. There is also a limit in terms of protection against moisture. and rarely fire resistant
At present, people have turned to use artificial wood like Wood Plastic Composite is becoming more and more popular in making slatted ceilings. Which substitutes for real wood that will have interesting properties? Let’s see.
Wood Plastic Composite
Artificial wood plastic composite or WPC is a material that is a mixture of wood and plastic with both hollow cross-sections. and solid cross-section The features of that product are outstanding. And where it leans, it depends on the proportions of the wood. and plastic that is mixed together
In general, there are 2 main steps in the production of wood plastic composites:
– Mixing wood and plastic pellets together
– Plastic composite wood floor molding By using various methods such as extrusion, extrusion, injection molding (Injection) and the use of a plane or a heat press to form (Hot Press).
In addition, the production process can also be classified into different types of ingredients as follows.
– Synthetic wood containing Polyethylene (PE based) mixed with wood powder.
– synthetic wood containing Polypropylene (PP based ) mixed with wood powder
– Synthetic wood with Poly vinyl chrolide (PVC based) mixed with wood powder.
For the sizes of WPC slats for ceiling (hollow type) that are popular in the market, there are widths ranging from 2-12 cm And the length is from 1-3 meters, with the market price from 200-1,xxx / line, which depends mainly on the size, pattern and grade of WPC wood.
Outstanding features
- No moth and insect infestation.
- It is durable. and is lighter than fiber cement of the same thickness
- Resistant to moisture. (depending on the mixture between wood and plastic, which one is more proportional than the other)
- There is a color inside the body, reducing the process of painting.
- Easy to install, can be trimmed like real wood.
- Can be recycled.
- Non-flammable and non-flammable.
- It is tougher than fiber cement type artificial wood. which can do some types of load-bearing structures
inferior feature
- When used for many years And in direct sunlight, the color will fade and may wilt.
- Not quite like real wood in both color and texture.
- Many plastic composites cannot be painted over. Therefore, when large and deep scratches occur, it is difficult to repair.
4. Frosted made of vinyl material.
Vinyl ceiling board is another type of ceiling material that is becoming more popular in the market. It is produced from UPVC or Unplasticised Poly Vinyl Chloride, which is a type of acrylic. Vinyl ceiling is often installed in large areas such as gas stations, office buildings. ,mall and public buildings รับสร้างบ้าน including general housing
The price in the market ranges from 350-1,xxx baht, the price depends on the size. and the pattern of the vinyl sheet There are many patterns to choose from, such as wood grain or various color tones.
The sizes that are commonly used in the market are available in sizes: width 14-25 centimeters, thickness 1-8 millimeters, and standard lengths of 4, 5, 6 meters (can order up to 12 meters in length).

5. The ceiling is made of aluminum material.
aluminum ceiling will look like a sieve plate or a long line like a batten which is produced from the smelting of bauxite to obtain pure alumina and bring alumina to melt until it is pure aluminum ingot and then processed with a mold of size and different cross-sectional shapes to obtain aluminum profiles for each ceiling application.
In addition, the aluminum material It also has properties that do not cause rust, rain resistance (high grade aluminum will effectively prevent water), sun or heat resistant. It has a strong and durable structure, so it maintains its shape without warping. It can also be used in a variety of ceiling decoration applications. has a modern aesthetic
Aluminum ceilings are often seen in large buildings such as bus stations, office buildings. Shopping malls or other public buildings to hide the system and install lighting or other equipment according to the use of that building but with the expensive and suitable for installation in large areas, therefore not commonly used in homes
As for the size and price of aluminum ceiling in the market, there is quite a wide variety. The price rate depends on the size. grade of aluminum and the main usage Each brand will have a different price for each model.
Outstanding features
- It is a durable, non-twisting material with a long service life of tens of years.
