Is there anything written in the IRC about sub slab insulation? Can only find info on foundation walls. Thanks, PK

    Thanks Malcolm!

    This won't help my cause to get an "old school" architect to follow any Pretty Good house details. He just can't imagine why I go through the trouble of placing insulation under a slab... Ugh. Glad the owners see it my way.
