SunTouch radiant mats are UL Listed for use with any type of finished floor if you embed it in at least a quarter inch of masonry. As always, start with a strong subfloor, secure the SunTouch, and cover with a self leveling mortar of your choice. Once this mortar is in place, follow the manufacturer instructions for cure time and then cover with laminate or carpet. Our Favorite Self Leveling manufacturer is ARDEX. Other Manufacturers are Custom Building Products and Mapei.
