Just bought a seasonal cabin up north in Maine.  We will only be using it for 3 seasons, but there are a couple of things I am going to do first chance I get.  It was built about 8 years ago.  Walls are insulated and the interior looks like a normal home except for the first 8" that are showing the cinder block that was placed on top of the slab.  Plus the floors are rugs and cement slab.  I will be putting down a floating laminate floor but want to cover the concrete block first.   Trying to incorporate some sort of 1" board foam insulation.  Any ideas?
