I just had a workshop (14*21 w/ hi ceilings) built that is attached to the back of my garage. Walls and ceiling are insulated with drywall attached. The concrete floor is 8 inches thick. I have heat in the workshop. Now I need to cover the cement slab with something that is easy, quick and inexpensive, but will help prevent the cold from coming thru the floor. The workshop will be used for all kinds of projects, but specifically wood-related projects. I am thinking about putting down a grid of 2x4's, then filling in with styrofoam insulation and then covering with plywood or equivalent (plywood is expensive). how thick should the plywood be and do I need anything on top of it or can I use it as is. thanks for any ideas.
