A gentle electric radiant heat system designed specifically for dry installation under floating wood and laminate floors. A low profile, line voltage system, it features gradual warmth from low wattage resistance heating of ultra-thin, flexible radiant heat film. Installed easily over a subfloor or over an acoustic/insulating underlayment as part of the overall floor assembly, it uses just 12-Watt per square foot to gently raise the temperature of the floor, conforming to the warranty requirements of many floating floors. The system, which sports an impressive 99% efficiency, includes temperature limiting properties so the film does not overheat. Its available in four convenient rollout mat sizes that will accommodate most any layout. Each mat has wires pre-attached for ease of installation.
