Do you require double thickness of plasterboard for ceilings?

Answer 1

No two are only used when there is a fire risk

Answer 2

Plasterboarding A Ceiling

Answer 3

Double thickness plasterboard with staggered joints is only required where you are trying to prevent the spread on fire, for example if you have a garage below a living area, then you would double sheet to stop fire spreading to the room above. You would also need to double sheet the ceiling if you live in a flat to stop the spread of fire to your nieghbour. On a normal ceiling between say a lounge and a bedroom you do not require double sheeting. however always double check with your local authority.

Answer 4

Ceiling plasterboard is always thicker than that used on walls to prevent sagging. When you go to by the board tell the person what you're using it on and they will provide you with the correct thickness

Answer 5

Assuming you mean drywall aka sheetrock aka gypsum.
No, however..

If your ceiling joists are more than 16" OC (on center), you will need 5/8" vs 1/2", or the span between the joists will eventually sag. If they are 16" OC, you can use 1/2", but I would still go with 5/8".

If you are drywalling an attached garage, then the wall between the garage and the home must have 5/8" drywall on the garage side. The attic space must be separated by a suitable fire barrier.

Answer 6

Where you are living or working has codes. There are requirements for ceilings and for walls. I have not heard of double thickness, because that would not be a code. One would ask double thickness of what? 1/2 inch, 3/4 inch, 7/8ths, etc. Find out the codes, probably the Internet could help you under construction.

Answer 7

There are a variety of plaster boards available - specialist boards like Fire Check are for this job in MULTI Occupancy Buildings and do away with the need to "double board". The standard thickness of a 1/2 hour fire ratining is 12.5mm British Gypsum (or Lafarge) board.

They both have extensive web sites that are well worth checking out- its better than putting up the wrong thing and having to take it down later....

Answer 8

Double thickness is not required for most housing. What is usually required is 5/8" drywall (fire code) on the ceiling of any space with living space above it. If you are looking for soundproofing you can purchase soundproofing board.

Answer 9

Assuming you live in the UK, I have never heard of this. Use the standard plasterboard which is readily available.

Bear in mind that for any rooms that may be damp, ie bathroom, you would need to use a waterproof plasterboard

Answer 10

a normal ceiling only needs a half inch plasterboard ..this will give you a half hour fire check.. but in a garage with rooms above you need double boards with staggered joints ..and then skimmed ..this will give you the one hour fire check..

Answer 11

Double thick. gypsum board walls are sometimes required by code for offices, apartments, and home garages. I've not heard of double thick ceilings.
