I have a wood fireplace in the corner of the living room with a wall
from floor to ceiling. The fireplace wall had this 1" or so thick brick
on it.. the wall looked like a backdrop to an 1980's stand-up comic
I took down the wall and noticed that the builders used regular 1/2"
gypsum board and not fireboard/cementboard or anything like that.
I then read that all drywall is extrememly heat and fire resistent.
I would like put some new drywall up in it's place. I will be using
this wall as a backer for putting up some stone vaneer. It is
desireable for me to have the wall being very thin.
Is 3/8" Gypsum a good idea for this purpose? Any other thin
