Tom,
I avoided some of the by sprayfoaming and THEN putting up the studs, so I lost around 2" around the basement (but when you are doing 60'x22' thats not much) but I can easily run addition wire if I need to. I actually but a full 20A circuit only for the trains. I also ran three 20A circuits to the garage (woodworker) for my tools. They are still not hooked up - but soon.
The spray foam is great - nice and cool in the summer and warm in the winter - almost a constant temperature. I was also struck by how quiet it was last night. It fills in everything. Whenever I have an insulation need in the future, I intend to use sprayfoam to get a good barrier. I used 3" on my basement, so roughly 20 R factor. Great stuff!

I glued 1" foam boards (R value 6.6) directly to the cinder block walls and then glued sheet rock onto the foam. Didn't spackle seams (no nail holes). That was 35 years ago and not a single problem or drop of water. At todays prices this would cost $7 per foot of wall. ($22 for a 4X8 sheet of foam and $6 for sheetrock)
Many great suggestions. Thanks to each of you!
Cordially,
Dennis
To make sure you have a room that will not fill with toxic fumes if a fire were to break out, it's best to have a continuous wall of sheetrock. Check the building codes for where you live. It's not acceptable, generally, to leave sheetrock seams untaped and unspackled nor to leave the sheetrock unpainted, exposing the combustible paper surface.
Thanks Arthur. Excellent advice that I will pass on.Cordially,
Dennis
