Gypsum board normally is used to do partition. It is slightly stronger then the normal plaster board for ceiling. The cost per sq ft will be very high if you use gypsum board for ceiling.

Sifu and contractors...8.5mm and 9mm board.....thickness difference is only 0.5mm. Does it matter if we use the 8.5mm instead of 9mm board?

30mm and 34mm aluminum support rod....can 30mm support 9mm plaster ceiling board?

I have contractor that quote me 30mm aluminum/8.5mm ceiling board at 30% cheaper than 30mm/9mm board. So just curious why the price different of so much. In dilemma whether to go for 30mm/8.5 or 30mm/9mm.

Wow...only RM0.02 per square ft for the board but quote from contractors increase by 30% if use 30mm support/9mm board as compare to 30mm/8.5mm board.

Since it is only 0.5mm thickness difference, does it matter if we use the 8.5mm board instead of the 9mm board? Anyone encounter any problems with this?
