False ceilings are used to cover huge distances or head rooms in a house. They can also be used to house appliances like extractors or air conditioners within that space. Other uses are housing lighting and alarm systems in a room. Different materials can be used to make this ceilings. mostly gypsum, timber or aluminum can be used as they are easy to mould into different shapes and sizes. Materials used should be light weight and also have good aesthetics.
A timber false ceiling can made by using tongue and groove or railings hanged from the concrete ceiling. When the beams in a concrete slab over hang down wards into a room, they can be covered using this method. The false ceiling will give a flat surface below the concrete soffits. The difference is that the original ceiling is still in place. This system is used for sound acoustics in restaurants within a building where loud music is to be played on stage.
The procedure starts by measuring the required headroom which should be a minimum of nine feet. This is measured from the finished floor level. Timber pieces of four by three inches are nailed along the wall surface in the lounge. The four inch side is put upright to give the point of anchoring the pieces that will span across the room. At the center of the room, metal hangers are fixed or screwed into the concrete soffits at a spacing of two feet.
Wrought timber of two by three inches is then fixed to the brandering and hangers. This is done across the shorter span of the lounge. The spacing is between them is six inches. The hangers are screwed into the timber. This timber can be hard or soft wood. It can also be shaped to give good aesthetics. After the frame work is complete, painting or varnishing is done. A trap door is done to allow for fittings like lights and air conditioners to be fixed.
