Note continuous layer of insulation. Very clever.

Food for thought for those of us without insulated cellars - ever notice the snow melted around a residential foundation?
An uninsulated basement up north here is kind of like perching a house on a huge concrete heat sink.

Cha ching! All's I need is a "I Love OPEC" flag.

I gotta git busy one of these days and insulate the interior cellar walls, which is kind of a pain to do to code.
