Hey- was hoping you guys could chime in with some suggstions on how best to handle a draft issue in the basement. I have 2 rows of cinderblocks making up the basement wall. The second layer of blocks does not go all the way up to the sill plate, but rather stops a little short of the ceiling (about 1 foot short). There is a pretty decent draft coming up from the gap created by the holes in the cinderblocks. I'm thinking of spraying in some Great Stuff foam to seal up the draft...not looking to fill the whole chamber, but just the top portion to stop the draft. Interested in your thoughts on the "plan", especially any concerns you have about moisure problems it could cause...
