The system has zero EMF and offers a lifetime warranty. Thermosoft’s 1/8-inch, contractor-grade heating mats are designed to minimize floor height and lay flat for quick installation. Mats can be cut and turned to fit any space. The 1/2-inch mat grid allows penetration of thin-set or self-leveling cement for one-step installation. Only one end of the mat needs to be connected to power. An inner foil liner eliminates electrostatic interference with appliances and telephones.Circle 316 on the Reader Inquiry Card.
