We have hydro radiant under hardwood.
We would like to put a couple of area rugs in our open floor plan to section off functional areas.
Should we use non-chemical materials such as wool or cotton to avoid out-gases?
What material should we stay away from?
Are there rug backings we should look for or avoid?
I'm assuming that having a mat under the rug should not be used as it would dramatically increase the Rvalue, reduce breathability and harden or negaively impact the rug/mat/wood floor when heated by the radiant heat.
Can anyone provide some insight?
I wonder whether the rug will act as an insulator and stop heat from getting into the room. I also wonder how much the trapped heat will affect the wood floor and whether the resulting shrinkage of the wood will open gaps at the joints
I would call the radiant heat manufacturer and ask these questions.
