You should consider the above very seriously as the ceilings will need to be redone if you wish to be able to change a non accessible ceiling into a demountable one.
Westinghouse Lighting Corporation has a line of fans that captures all of these needs and they claim can be installed in 15 minutes on average. The weak link in all of these improvements is the ceiling box itself. This is the component that the fan is attached to and must bear the static and dynamic loads of the fans operation. It also houses the electrical wiring for the fan. This utilitarian component has been under going improvement for the past 10 years or more to make its' installation quicker, cheaper and easier than the traditional metal box of yesterday.
The electrical contractor of today is using products that increase his productivity and maximize the potential profit of his labor. They have a large choice of nail-on products that already have the fasteners attached to the ceiling box and all they have to do is hold it in place and nail or screw it into a joist or truss for it to be secured. Many of these boxes are thermoplastics which are inexpensive and easy to manufacture. They also have the added advantage of not needing to be electrically grounded so this saves the additional labor that metal boxes require.
