Have you considered cork? Not a good conductor, for radiant heating, but
very good for the warm springy feel under bare feet.

Cork, mmh? That's worth considering....

How would cork compare to ceramic tile, in terms of durability?
Maintainance? Would our pet (a husky) damage it? Would a cork floor
require an underlayment ? If so, what type? Since cork is a natural
insulator, should we forget about radiant heating and revert back to
forced air (which is what we currently have)?

TIA
