I am planning on building a small house 35 x30 that will sit on a slab on grade. I'm planning on installing some kind of wood floor so my question is. Would it make any sense to install rigid insulation between 2x3 every 12 inches and cut down on the amount of insulation under the slab? Also, how do feel about using this 1 1/2 inch space to run pex and electrical wires if needed. I only discovered this site yesterday looking for information on slab on grade, a lot of really good information here. Thanks
