The garage is 1464 square ft, with 11' side walls. Basement is 2374 square ft with 9' walls. 1 wall of the basement is a walk out, 45' long. 3 windows-36"x54" and a patio door-72"x82". Wall is 2x6 with R-21 insulation, no other windows/doors in basement. Not really going to worry about keeping garage real warm, mostly to keep truck/car thawed in the winter-perhaps around 50 deg. With 3 garage doors(9'x8') it would be tough to keep real warm. Garage door company claims an R-13, just don't buy that when there is only 1 1/2" of insulation sandwiched in there. Floors are 5" concrete with 2" foam taped in place, vapor barrier under that and at least 6" of 3/8" clean chips I smoothed under that. Also have 2" foam glued to the foundation on the inside down 4' for a thermal break. I forgot to measure the Logstar last night when I got home. Maybe I can find it on my paperwork(doubtful). Just got my 1 1/4" copper pipe in this morning so maybe I can start the inside piping.
