False ceilings or suspended ceilings reduce the height in rooms and also perform many other functions. Ceiling boards are the materials used to create such ceilings. A hollow space is created between the actual original ceiling of a room and the false ceiling, which can then be helpful in many ways.
These suspended ceilings can improve aesthetic appearances and proportions by managing height. They can be used to run ducting, electrical and other services, and also hide any structural members so that the look of the space below is enhanced. It can also help to act as insulation and can help to reduce the volume of air that needs to be treated in HVAC systems. They also help to improve the acoustics in a room. They are often a design element in interior decor. They can easily accommodate lighting systems to provide the desired lighting effects.
According to AllIn fb page, false ceilings are made up of primary and secondary structural members that can be made of metal or wood. The main ceiling boards or tiles are then supported on this framework in the desired configuration. The framework can also be used to support any ducts, lighting or electrical work. Ceiling boards can be made from Plaster of Paris, gypsum boards, aluminum, mineral wood board, PVC or UPVC, wood, glass, acrylic, or polystyrene.
All the materials listed above for making ceiling boards for fitting into false ceilings have their own characteristics, and actual usage may depend on architectural preferences, desired functions, and budget. Climatic conditions can also play a part in their selection. Framework for false ceilings can be exposed or concealed. When exposed the ceiling boards will have a grid-like appearance, whereas concealed framework allows the ceiling to present a uniform and continuous appearance, no different from the actual ceiling of living spaces. The interiors of these ceilings are difficult to approach if any defects or changes need to be made to the concealed services. In the case of an exposed framework, each ceiling board can be individually removed to access the portion that needs any work done on it.
A ceiling board makes for an overhead interior surface of a room that covers the upper portions of the room and is rarely a structural element but can give you a finished surface. It conceals the underside of a roof structure and helps to give architects the scope to control and govern the looks of a room. Ceiling boards can come in many sizes, with gypsum boards having widths of 4 feet and lengths of up to 12 feet. This size allows entire areas to be covered with a minimum of joints. The framework will have spans that allow these ceiling boards to span across them without sagging and is generally limited to 24 inches.
False ceilings will make any room space to have lesser volume, which is a definite advantage in reducing air conditioning loads. They do however add to risks of fire and must be designed to take this into account, through the use of sprinkler systems and other measures.
