Insulating under in-floor radiant heat
I have in-floor heat. The tubes are in metal attached to the undersides of the subfloor.
I put 3-inch fiberglas insulation between the joists and then stapled plastic to cover it. I was told the the fiberglass is absorbing the heat instead of reflecting it back up. Should I get the foil bubble type so it reflects the heat back up?
I want it to be as efficient as it can. The house is about 3000 sq. ft. It's a log home.
