This may be a dumb question, but is there such a thing as "insulated floor tile"? I can't afford radiant heat on my basement floor, but the cement slab is cold. It's a finished room that I use for TV watching, and I'd like to be able to sit on the floor. When the kids are visiting there are never enough chairs. As it is now, the floor is just too cold, even with pillows. Does anybody make an insulated tile or something along those lines?
