I have a sun porch off of the north west side of our rancher. It already has triple pane windows installed by a previous owner and yet the ceiling and floor have no insultion what-so-ever!
I am interested in opinions about insulating the floor space. (I plan to insulate above as well but that seems more logical to me). It was originally a concrete slab and the previous owner who was disabled put 2 x 8's on top and a wood deck over these to gain access to the home. I was interested in adding a heated tile floor for cool fall nights and days. However, I am concerned about condensation in light of the space between the slab and the decking. How should I go about insulating this over a slab?
Any thoughts would be appreciated.
