Im building a new addition in bergen county, nj -- 18'X18' with a full but unfinished block basement. exterior will have a bituminous coating, skim coat, gravel and perf pipe at the footing, and I'm planning on applying one of the cultured stone or brick products on the exposed portion of the wall (about 1.5' above ground). inside will be gravel bed, 6 ml poly vapor barrier, and 4" slab on the bottom. this will be an unfinished basement used for storage. how best to insulate? would prefer to do inside I think? basement ceiling should be as well? even if (or perhaps because?) i use radiant heat? thanks as always.
