I just read through the several suggested methods to prep the surface above WarmBoards to receive ceramic tile. It wasn’t clear from the different options if any have a lesser or greater impact on the upward transfer of heat into the room. Can you advise?
Many tile installers prefer their tried and true methods, which is why we offer 7 options to make things as easy as possible. That said, the Backer board method is the one we recommend. It’s among the easier methods for installation and will give you the best heat transfer as well.
