Need help with insulating a block house with crawl space
I am remodeling an old family house that was built in the 50’s, that is structurally in great shape, and is in middle Georgia (climate zone 3). The house has block exterior walls that extend down 18 inches into the ground to the footer. The crawl space is slightly below grade, but seems to stay fairly dry because the house is sitting on a small hill. I am doing a complete remodel, but not sure how to insulate without causing myself problems down the road. The exterior walls from the inside out consist of several layers of paint , plaster, block, and couple more layers of paint on the exterior. It was stripped with 1x4s and then vinyl siding, but I am removing this because it is old and brittle. I will be replacing the windows and want to insulate it well for my area. The crawl space has two access holes one on the side and the other on the back of the house and no other vents. There is no plastic under the house and no insulation. I don’t know of any other houses in my area that are block with a crawl space, and the contractors I have talked to haven’t seen many houses like this, so I am getting varying opinions on how to insulate. My wife likes the look of the plaster walls but we can cover them up. The crawl space is only about 12 inches high, so i can get up under there to do some work but it is fairly tight. I have looked at exterior insulation, but not sure about the details with a crawl space. Do I condition the crawl Space? Would it just be easier to get the details right by insulating the interior? I’m not looking for the cheapest way, but don’t want to spend money that isn’t going to help that much either. If I go with external insulation, what are some suggestions about siding and where the siding would contact the ground. Stucco on foam?
Thanks in advance for the help.
