Answer: The best integrated ceiling material now is magnesium-aluminum alloy. Waterproof coatings, PVC sheets and aluminum-plastic panels are commonly used materials in kitchen and bathroom ceilings. Waterproof coating has the characteristics of easy construction, low cost and various colors. However, local peeling and fading may occur after long-term use. PVC boards are widely used in today's homes. They are easy and fast to construct and come in rich colors. Their main features are good waterproof performance, easy cleaning, and no need to replace them after long-term use. However, the traces of industrialized mechanical production are more obvious and lack of personalization. With the development of the integrated ceiling industry, materials that have become increasingly popular in recent years are aluminum-plastic plates and other materials. They are stamped with lightweight aluminum plates at one time, and the outer layer is sprayed with plastic using a special process. The colors are bright and rich, do not fade after long-term use, and have waterproof properties. Excellent, simple construction and no deformation. But the relative cost is also higher. However, material selection is only the first step. What is more important during the construction process is the ventilation and moisture removal settings so that the humid air in the room can be discharged in a timely manner.
