Our family room is built on a slab foundation (unlike the rest of the house). The room is consistantly cold in the winter and keeps moisture year round. Walls and ceiling are well insulated however the only barrier between the slab and us is plywood, a carpet pad and wall to wall carpet.
We would like to replace flooring with wood however are unsure how to properly insulate the floor to keep room warm and decrease moisture. Please help with suggestions.

Sorry to tell you, but you do not have many choices. Since
you concrete slab did not have heat pipes in it, you can only work on the top of it. The simplist solution would be to build a false floor with insulation on top of your concrete slab. This would not be too bad a project. Probably a couple of days with 2 guys who know what they are doing. Hopefully, you would have room to raise your floor up between 1 1/2" and 2". If you would like more detail how to do it, just e-mail me direct. Good Luck
