What size and gauge should metal studs be for a residential sheet rock ceiling in a kitchen that is 10' x 12'? What is the proper thickness of sheet rock? =TB
Residential dry wall ceiling are typically one layer of 5/8" fire resistant sheetrock for one hour fire protection and two layers if a two hour protection is required (for an apartment up stairs).
The joists are usually 33 kpsi, 2"x6" in none load bearing cases.
