This video shows an install of EASYHEAT - WarmTiles radiant floor warming cable system using Edge Strip Kits and self-leveling underlayment (SLU).

By using the Edge Strip kits, the SLU is contained inside the desired area. A strip used at the door opening protects the SLU from escaping into the adjacent areas.
This installation method produces a flat tile surface with the heating wire completely protected from damage during the tile installation stage.
