Normally 2.4mtrx1.2mtr size plywood being used for this type of ceiling.In this plywood panels also two types are commonly used. one is commercial type , which is paintable grade. Another type is decorative , which needs clear varnish. Depends on interior design , we shall choose the type of plywood panel.To cover up the joints in between plywood, wooden mouldings , coverstrip is used. When you apply contrast colours to coverstrip to plywood panel, it will be added beauty. To cover the corners you can use wood moulding cornice. This will look like decoration.
Choosing of the plywood for ceiling also important.First thing is the grade which we must decide. AB grade will do better for ceiling. 'A' facing outside whereas 'B' grade inside. It is advisable paint bothside inorder to avoid moisture absorption and deteroriation of plywood.
Second thing make sure the plywood is with of glue line poison. This will help us to avoid insect attack on plywood. Manufacturers always mention that they add glue line poison to plywood.Even you can ask for the spec which they use while manufacturing.

soft board are named based on the density of the material. If the density is between 300-5ookg/m3 , the board is called as soft board. Handling of soft board should be with care. Otherwise it breaks. Because of its low density , it is acting as insulation material also. In one way it has acoustical properties , which reduces the noise level.
Avoid using wood screws while dealing with soft board.

So, you must consult the wood technologist before opting for treated wood for ceiling. As such the price may vary , but it is good to treat the timber before using.

Hard board also act as sound reduction panel.
Wood Moulding ceiling
This type of wood moulding come with tongue and groove, which can be joined together and nailed at required places. It is advisable to go for square joints , so that we shall avoid the gap. Some people prefer v type joints to get some fantasy. Here we do not require any type of coverstrip and cornice. This type of wood moulding ceiling are stronger than other type or ceiling except planned wood moulding. Nowadays most people prefer this type of ceiling for decorative purpose and easy working. Even natural finish is possible for this type of ceiling.

Decorative moulding which covering the corners and joints look like decoration. Any types of decorations to the ceilings can be made for functions.
