Question by Kris: Ceramic Tile over basement Concrete floor with radiant heat system under tile – need for backer board ?
We want to tile our concrete floor in the basement and use the radiant heat grids to heat the rooms. We have heard that we need to use a backer board to keep the concrete from cracking from the heat of the heat system. do we need to use backer board?
Answer by josephrob2003
the backer board is more to hold in the heat, or you would lose it to the concrete, its well worth doing it, just think of the money you would save, and it would be far more efficient, and quicker in warming up.
