Just finished my new shop, it’s 40’x48’x16’. I’m currently working on the floor and plan to have in slab radiant heat. I put down a 6 mil plastic vapor barrier followed by 2” extruded polystyrene insulation. I am going to pour 6” thick concrete with steel in it. From what I’ve read it is inefficient to to attach the piping directly to the top of the insulation in a 6” slab bc it’s too far from the surface. What do you guys think? The other option is to suspend rebar and attach the piping to the rebar putting it closer to the surface but deep enough that it won’t be cut when cutting joints. If I attach to the insulation it will be easier to pour because I could use wire mesh and just pull it up as we poured. I’m afraid to attach the piping to wire mesh bc of it floating too high. Looking at doing 3/4” line on 12-14” centers with 300’ max per loop.
