I'm planning to insulate and sheetrock my garage. Surrounding the door going into the house is some type of fiberboard that's about 15/16" thick. As you can see in the photos, the distance from the edge of the stud to the face of the 1/2" drywall is 1 7/16". If I'm going to add sheetrock to the attached wall, how should I handle that 15/16" space to line up the drywall?
I was thinking I could rip some strips from 2x4 construction lumber to shim the studs out a bit, but I'm not sure if that's the best option. Would it make more sense to buy matching fiberboard and screw the drywall through that?
