Strategy for Minimizing Floor Height Using Radiant Heat Floor Piping
Hello all, I am planning to lay pex pipe for radiant hydronic heating in my basement lower level. Currently there is a 4 inch slab with a vapor barrier under that. I want to minimize raising the floor since it is a remodel but I realize I will be raising up door thresholds and reframing stairs. I am planning to glue down 1 inch of R-5 rigid foam, then glue 5/8 inch plywood sleepers directly to the foam and setting 3/8 pex A tubes into heat transfer plates between the sleepers. Then an engineered wood floor that is 1/2 inch thick on top of the heat plates and tubes and sleepers. I am wondering if this is a fairly acceptable approach? Since I wish to increase floor height as little as possible, I’m hoping that sleepers placed directly on foam will be rigid enough if i use adhesive all around?
