Question about floor treatment.
2" thick radiant slab on R20 +/- insulation.
Am thinking that under the box bed, and possibly under kitchen cabinets, it would be a simple matter to place a sheet of XPS or equal on top of the floor, hidden under the furnishing so that the BTU's are encouraged to radiate into more useful places.
Also to correct what may have been a mistake on my part, I placed pex within a few inches of the two doors to counter cold air entry, am thinking that in cold weather (20 below), it might be a good idea to place a rug at the entry ways, to help keep the slab warmer. Entry ways both have excellent (ICF) edge insulation Trying to avoid anti freeze in the system.
Am also thinking of a rug in front of the often used fireplace, again to encourage BTU's to work more efficiently.
Finish floor will be ceramic tile, with few rugs etc. Work to recommence in about a month.
Thanks for your thoughts.
