Drywall installation
 

I inclosed my porch to make a 3 season room. I removed the siding from what used to be the extior wall. That left the sheathing exposed. I am putting wall board up to finish the room. Can I attach the wall board directly to the sheathing, or do I have to put furring strips on?
Thank you,
Eric

I don't see any reason you couldn't attach directly to the former exterior sheathing.

As stated, it can be installed directly to the sheating.

Infact, we will be doing the same thing on an addition that we built last week. Just make sure that the sheathing, itself, is properly secured to the framing.
