whipped - my goal is for me to learn enuff to lay the PEX tubing in - test it (pressure test??) and

- I appreciate that a competent professional can do good work, BUT in THIS town I have found thru bitter, bitter experience that it is nearly impossible to ensure you have found one. Many many others have had the same experience - no idea why this town is so bad for getting decent contractors.

Jim - sorry if I was short - have had a LOT of gf drama recently... anyway, the degree of insulation is a question for me.

One scenario has Al plates with longitudinal areas to hold the PEX tubes, next layer down is batt insualtion, & I think the Radiantec stuff includes a foil radiant reflective layer; last layer will be sheetrock.

Other scenario has "clips" 2 inches below floor to hold the PEX tubes, next layer down is pink Foam Board insulation, then batt insualtion; again the last layer will be sheetrock.

At least that is how one contractor explained it to me. He had some odd ways of explaining things, so who knows...
