Warmup® Underfloor Matting Systems are designed to be tough enough for professional use, yet easy to install for do-it-yourself enthusiasts. The radiant heating cable is attached to a tough fiberglass mesh.Simply roll out the mat before laying your flooring. If necessary make any cuts to the mesh (not the wire) and fold the matting over to fit the desired heating area. Then have a qualified electrician connect it to one of our programmable thermostats. - See more at: http://www.warmup.com/us/electric-floor-heating-mats.phtml
