Comparative analysis of five ceiling performance
The ceiling is a very important part of the home decoration. In simple terms, the ceiling is a kind of material used to decorate the ceiling. Now there are many kinds of ceiling materials on the market, and the suitable style and actual effect are also very different. The style of the ceiling is quite important. According to industry insiders, the types of ceiling materials on the market are roughly divided into five types: integration, PVC, gypsum board, aluminum gusset and glass. The owner needs to identify and select the suitable place for the ceiling.
Integrated ceiling
It is the most commonly used type in the industry, and it is also the latest type. It has a unique advantage and is popular in the world. For example, it is a collection of lamps, exhaust fans, Yuba and other products in a ceiling, not only beautiful, installation It is also very convenient, and can be effectively separated according to the function of the room, so that the light source has a limited effect. Many people think that the thicker the ceiling, the better. In fact, the choice of ceiling can not be pursued thickly, as long as the national standard of 0.6mm can meet the use of the kitchen bathroom.
PVC ceiling
Many people may be unfamiliar with PVC ceilings because they are quickly eliminated by the market, but they also have irreplaceable advantages, such as low cost, large variety of colors, easy to clean, easy to lay; why are they eliminated? The point is that the practicality is not strong. After installation, the owner himself is not allowed to disassemble it. If there is a problem, it must be handled by a professional. If you catch a leak or circuit repair at home, it will cost more, and it will take a long time to find it. PVC ceiling is easy to age and discolor.
Plasterboard ceiling
From the current point of view, its existence is still more common, in addition to the bathroom and kitchen, any place is applicable, it has advantages that other varieties can not match, such as good sound absorption, fire retardant, can make a variety of shapes, but for a long time It is easy to foam and discolor, and before the formal construction, workers need to measure the wall level first, otherwise the installed ceiling is prone to tilt or high and low drop. In addition, it is recommended that you use stainless steel drywall nails to fix the plasterboard. If the nails are rusty, it will affect the overall aesthetics.
Aluminum gusset ceiling
This type of ceiling is still quite extensive from the current point of view. It has several material types, such as aluminum-magnesium alloy and aluminum-manganese alloy. The latter has high hardness and good corrosion resistance, commonly known as stainless aluminum. The former is increasing hardness. At the same time, some brightness is added, which makes the ceiling texture good and the decoration effect strong. It should be noted that many inferior substrates on the market are made of garbage aluminum, recycled aluminum or earth-aluminum. The products they produce are easily deformed and easily oxidized. They may also contain harmful substances such as chromium, lead and mercury, although the price is low. Hard, but it is best not to buy.
Glass ceiling
These products are generally more common in public places. They are decorated with stained glass to the ceiling. The light source can be placed inside, which can increase the aesthetic effect. It is mostly used for partial ceilings. It is suitable for people who pursue art and color effects, but glass ceilings. The acceptance of the glass should pay attention to the variety, specifications, colors, patterns, fixing methods and other factors of the glass.
