My wife and I are planning on renovating the kitchen of our house which was added on as a summer kitchen to the main house at some point long ago. As it stands now, 3 of the kitchen walls are exterior double brick, and as best as I can tell the interior finish is a plaster board applied directly to the brick. (There's likely some kind of furring or lathe in there, but I don't know.) In any case, I've had a lot of conflicting advice given to me on how I should go about refinishing the interior space and I was hoping I could get some advice here. Right now, this is the plan I've come up with based on an amalgamation of the bits of advice I've been given: Tear down existing plaster board (and lathe if it's there). Fasten 2x2 furring strips directly to the brick with Tapcon screws. Insulate between the furring with foam sheet insulation. Hang Drywall on furring. Does this sound right? Additionally, there are a lot of questions that I still have about this process that I've been given wildly different opinions on. Specifically: Do I screw into mortar joints or into the bricks themselves when attaching the furring? Do I need a vapour barrier between the drywall and the furring? Will this method provide enough airflow around the brick to keep it healthy? All advice is much appreciated. I've never attempted anything on this scale before, and I want to make sure I do this right. Thanks in advance!
