The first floor is fine, walls are 14" thick. Inside to out: Drywall, R12 fiberglass between 2x4 wall studs, 8" concrete block, 1" rigid foam, firing strips with 3/4" rigid foam between them and finally the vinyl siding. Still does feel cold near the outside walls. The floors are concrete (slab on grade, no basement) but even the thick living room carpet feels cold near the walls. It is super quiet on the first floor with the thick walls. Ceilings have R50 fiberglass except where the upstairs dormer is. Unfortunately the dormer is only 2x4 construction with R12 'glass (I assume, haven't torn into it yet)with 3/4" rigid foam on the outside under the vinyl, and the ceiling is also only R12, far as I can tell. It was an add-on at some point in the past (I'm guessing late 1960's) and not built really all that well to be honest.
