    You need to peel off inside walls to get to insulation... take out all of the insulation and install atleast 4 inches thick of styrene like the above guy showed you. That stuff shown is 1 inch... you need 4 inches of it.

    A building supply house willl have it , or can tell you where to get it cheaper.

    After you cover insulation back up , seal all cracks with silicone.
