Concrete backer board for tile
I would like to install ceramic tile over radiant floor tubing.
Can I do this with acceptable results? 1. Install PEX on top of existing subfloor and use furring strips of appropriate thickness between loops. 2. Install 1/2" concrete backer board on top of furring strips. Heat transfer plates and thermal mass not an issue at this point. I am more concerned about structural integrity, i.e., will back board be strong enough to support tile without flexing or cracks in either tile or mortar. -- ================================================= Franz Fripplfrappl |

No. The backerboard must be fully supported, and preferably adhered to the subfloor. R |

You have it way backwards.
You need to do some reasearch. 1.) Thisnset 2.Backerboard 3.Screws 4.Thinset 5.) Heating Pad(on top of wet thinset, let it dry then lay tile like normal) 6.)Thinset 7.)Tile You'll use easy mat or 1/4 inch hardbacker not 1/2 inch www.Totalflooring.org Post question on www.totalflooring.org and get professional answers if you like. |

Doesn't seem to be too professional of an answer when you ignore what the OP wrote. He is installing PEX, not electric radiant, so I'm not sure why you're trying to redesign his system for him. A goodly number of electric mat radiant manufacturer's prefer the mat to be attached to the backerboard prior to the thinset being applied. Wedi board is far superior to using backer board as it insulates the subfloor and more heating dollars end up in the conditioned space instead of in the structure - one manufacturer specifically recommends Wedi under their mat.
