insulating above a concrete slab for wood flooring
I have a grade level slab which I’m planning to put ¾” hardwood flooring over.
I’d like to put some insulation down before I install the flooring.
I only have 1½” total clearance before the top of the threshold.
I was thinking to put 1/8″ layer of vapor barrier/felt padding. then a layer of 1/2″ rigid foam, or the other way around.
The wood floor will likely have to be glued down as there is nothing to nail it to.
