wrote:
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.

Seal the concrete with a penetrating liquid and/or plastic sheet. Lay
down tubafour sleepers (12 or 16 inch centers depending upon weight of
machinery) with insulation between. 5/8 or 3/4 T&G OSB atop that. A
light color primer to enhance the lighting. Underfloor wiring or dust
collection is optional. Should last and support some pretty serious
machinery.
