Radiant heat insulation between conditioned floors
Hi, I read your article questioning the need for radiant heat on a second floor. My question/concern relates to this but is particular to my situation.
I have installed radiant floor heat (not yet charged or insulated) in the first and second floor (separate zones) of my old farmhouse. I have all new low e windows and will be using spraying poly on the walls. The house will be tight! My contractor thought I may never use my second upstairs zone particularly, since I’ve also plumbed in a wood stove on the first floor. The bottom floor is 800 sf and the second is only 400 s.f.
My concern is that it may get too hot upstairs if the woodstove is on and how do I sound proof between floors? The “TV” room will be directly below the bedroom. How much or should I even insulate between floors. I thought of using rock wool for sound deadening yet limited R value to allow easy heat transfer between floors. Your suggestions/opinions will be of great help. Thanks
