I live in Florida and I am removing the original outside siding to replace with cement fiber board on my 1910 house. There isn't any plywood or clapboards under the siding and I can see the drywall/plaster and limited insulation when I remove the siding. Should I install kraft faced or plain insulation from the outside? If I use the kraft/paper faced, how will I staple it since I am working from the rear? Will the paper be a sufficient vapor barrier for the high heat and humidity in Florida? Thank you.
