The outside door to our basement is basically just a bunch of 1x8"pine
planks nailed together (like an old shed or barn door).
As you might imagine, the door let's a fair bit of cold air conduct
through (I have already caulked the gaps). I would like to insulate
the door, at least in the winter, until I redo the basement and put up
a real door and frame.
I was thinking of maybe just tacking up some styrofoam like panels to
either the inside or the outside of the door.
Any suggestions on recommended products and approaches?
