The TempZone Twin Conductor Cut & Turn Roll has the intrinsic advantage of maintaining low electromagnetic fields (EMFs). The addition of the twin conductor version of TempZone Cut & Turn Roll allows WarmlyYours to enhance their superior flagship product - the hottest in floor heating (utilizing a full 15-watts/sq. ft.). With a single termination cable you can layout the entire length of the cable without returning the end back to the thermostat. Installation is faster allowing for easy free form design with the ability to remove the cable from the tape adhesive. You should only plan to heat an open area not underneath permanent fixtures such as vanities cabinets tubs showers etc. This roll can be cut and turned to fit any size or shape space. The TempZone roll needs a WarmlyYours approved thermostat to operate. Use one of the following: SmartStat (TH115-AF-GA-08) EasyStat (TH114-AF-GA). Please view those 2 products for more details to complete your floor heating system. If using radiant floor heating on top of a concrete subfloor it is recommended to use WarmlyYours Cerazorb underlayment (CZRG-SH5mm-24x48); this will provide a more efficient system.
