In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
Part of my home that was a house addition (14'x24') was built on an uninsulated concrete pad. I live in Western NY so the floor gets very cold in the winter (as does the room).
Im adding on to the room 10' out (making it 24'x24') and building a new roof. The only heat source for the room is a gas fireplace and I want to add radiant heat to the entire completed room.
What are my options for installing over the uninsulated pad and for matching the existing pad? Should I match the existing floor with a poured concrete pad or with wood framing floor and joists? I do have the option of raising the finished floor elevation several inches if necessary so I could get some foam boards over the old pad. Im not keen on breaking up the old pad and insulating underneath but its possible I would do it.
Any advice would be appreciated.
