Under Floor radiant Heat help

My new house I just purshased has radiant heat installed under the floor between the joist. The hydronic Radiant heat is fixed to these floor joists about 1 inch below the subfloor. It has just batt insulation R-12 ontop of it.
I was woundering If I should install a foil under the batt insulation Between the radiant pipes and insulation or above the insulation before drywalling it. If so what type of foil should I use?
Thanks!

If its a rocksol insulation, it will be fine, if not the foil is a good idea.

You should use foil. It should go from top to bottom...your sub floor, your heating tubes, the reflector then the insulation. This way the heat is reflected up.....you want your floor to be warm not the ceiling below.
