QUESTIONIs there a “best” tile to use over radiant heat. I am interested in using travertine with a tumbled finish. Do you see a problem with this? Thank you.
ANSWERANSWER - As long as the tumbled travertine tile is installed correctly or a correctly installed radiant floor system, it should not be a problem.
Note that using a natural stone will require more maintenance to maintain the stone. You should seal the stone to help protect it from staining and to make it easier to keep clean. Sealers have to be re-applied at least annually unless you like the worn patina look.
Porcelain ceramic tiles are the most resistant to staining and other issues because they are very dense and low absorbing.
Either the natural stone or the ceramic tile will be a good conductor of heat for the radiant floor system.
