Insulate bottom 6' of external wall?

clayfarmerFebruary 24, 2008

My interior basement walls are 8' 6" high, so after I installed 1" XPS, the bottom 6" is still exposed. My question: Is it necessary that I "fill in" this bottom 6"? I'm thinking since it's 8' below ground, maybe its not necessary?

Don't know, but it's easy enough to do. (I use a serrated bread knife to cut that stuff.)

I score it with a sharp knife along a straight edge then snap it.
