< The Underfloor Matting system is easy to install and includes a cable attached to a tough fiberglass mesh. An installer simply rolls out the mesh before laying flooring and connects it to a thermostat. Designed for tile flooring, the system also is available for hardwood, laminate, carpet, and vinyl. It costs as little as .13 cents a day to operate. Warmup Inc. 888-927-6333. www.warmup.com.
