I am installing attic stairs in my finished garage. I noticed the ceiling
is sheetrocked with 5/8" sheetrock usually associated with fire barrier. I
am tempted to attach a piece of sheetrock to the ceiling side of the
trapdoor panel of the stairs, but I think it may cause the door to become
too heavy and interfere with the operation of the door. The sheetrock would
be 22"x 53 1/2". Does anyone have some information they would like to share?
