Economic criteria are the top priority for houses with corrugated iron roofs, so gypsum ceiling has many outstanding advantages over other types of plastic and cement ceilings. It is the most cost-effective, fireproof material and provides both better insulation and soundproofing. A gypsum ceiling can withstand a small amount of water seepage for a short period of time before evaporating. However, soaking the plaster ceiling in water for an extended period of time will make it less durable. When there is a leak or water seepage, the homeowner should repair and replace the corrugated iron roof as soon as possible because there is no replacement material. Stains on the plaster ceiling also aid in locating the source of the leak, allowing the homeowner to detect it sooner.

Based on the international standard BS 5234, impact resistance of walls/drywall is classified into five bearing levels:  
1) poor bearing
2) moderate load
3) extremely powerful
4) extremely heavy load
5) heavy load  
Most common wall/drywall is strong enough to support the hanging of most household items such as paintings, photos, and thin-screen televisions with thin screens, etc. Other heavy items, such as kitchen cabinets, air conditioners, and bookshelves, must be planned ahead of time so that construction workers have adequate reinforcement details inside.

The wall/drywall structure has many independent voids that give it a hollow and soundproof feel. However, sound travels faster and better through solid matter than through hollow matter, so wall/drywall is actually more soundproof. Because walls/drywall are used inside the house, break-in resistance is not required. However, the wall/drywall system can strengthen the inner steel layer to increase resistance to intrusion.

Termites can eat and nest on gypsum board production paper because it contains no toxic substances. As a result, proper termite treatment is required to maximize the duration of its use in a home.

To address this issue, the homeowner should install a wall cladding system that includes an inner layer of cotton insulation, an outer layer of plaster, and a metal framing system. This wall cladding system, with a maximum width of 75mm, will provide maximum efficiency without taking up too much apartment space. Furthermore, the wall cladding system contributes to the apartment's sound insulation and noise resistance.

Because wall/drywall is very light at only about 20kg/m2 and easy to install, you can install it almost anywhere you want, unlike brick walls, which require floor reinforcement. With simple tools like a ruler, paper cutter, drill, pencil, and nail hammer, you can install the wall/drywall yourself.

Most finishing and decorative materials on sheet surfaces, such as water-based paints, stickers, wood panels, and ceramic tiles are suitable for use on walls/drywall. Instead of cement, it is recommended to use specialized glue with ceramic tiles. Ordinary bamboo shoots to increase the ability to adhere firmly to the plasterboard's paper surface.

Electricity and water lines can be easily installed in drywall without chiseling and with high mobility. Simply:
1. Assemble the metal frame
2. Place the electrical and water systems through the holes in the frame.
3. Place the panels on both sides of the frame and you're finished.  
Dismantling, relocating, and installing more is also simple, with minimal dust and noise.


Gypsum board is made primarily of gypsum powder and paper, and it does not contain asbestos, making it non-toxic to both users and installers.

Even if a fire breaks out, gypsum is non-combustible and does not emit toxic gases like plastic sheets, sponges, and other synthetic materials.

There are two types of gypsum ceiling applications available today:  

1) drop ceilings, also known as floating ceilings, are ceiling types that are assembled from finished products and do not crack when subjected to high vibrations. They are simple to build, with easy maintenance and repair of the electrical and water systems above. Corrugated iron factories, offices, apartment corridors, schools, and factories frequently use this type of ceiling.  

2) concealed ceilings are a type of ceiling with a high aesthetic value that can be used to create a variety of ceilings. These ceilings provide various texture patterns suitable for stylized, formal, traditional, or contemporary design and are popular for decorating larger halls, living rooms, and bedrooms, among other places. Additional surface finishing steps, such as painting or pasting paper, are required for concealed ceilings. As a result, homeowners can select the best option for their needs.

Structures more than a century old in Europe and the United States have confirmed that drywalls and ceilings have the same lifespan as normal bricks or concrete walls, when that drywall is only installed inside the house and is never exposed to water.


Zeit Gypsum covers the following defects when products are used correctly and in the recommended environment:
1) peeling paper
2) sagging panels

Common problems include:

1) mold, yellow spots due to water damages.
2) termites
3) cracked plaster joints.

To avoid water leaks that cause stains, mold, and damage to the ceiling, we recommend careful inspection of the water pipes in all important places, including inside the wall, above the ceiling, and in roof holes. Avoid strong impacts with hard objects, especially on walls. When hanging light objects on the wall, use specialized screws or shoot screws directly into the frame (butterfly screws). When hanging heavy objects, it is best to remove one side of the plasterboard, reinforce the inner frame, reassemble the sheet, and finish the surface. For renovation, we recommend repainting and regluing.
