Basement insulation

Tom,
I read your articles with great interest as being more efficient is always
the best way to go.
Your comments about basement insulation are interesting as I am considering
installing foam insulation in my home and am not sure about the best way to
go about (type, R-value, adhesive, distance below grade, etc.)
Any help on this one?
Thanks
Rob

Hi Rob,
You can use fiberglass, if there is a studded wall and a vapor barrier
against the concrete wall. Spray foam is the gold standard.
Whatever you do, R-19 or greater is the goal. The critical area to insulate
is the part of the wall that sees the outside air. The parts below ground
are slightly less critical.
