Feature: 3” pre-spaced wiring is designed to reduce installation time and ensure even heat distribution. The Mesh can be cut and flipped or rotated to provide maximum coverage; wires can also be removed from the mesh to help get into those hard-to-reach areas. The Self-Adhesive mesh on one side and double sided tape on the other, ensures the mat adheres to sub-floor and lies flat even when flipped or rotated. Radiant heat does not dry out the air, circulate dust or aggravate allergies. Out of sight, no unattractive plug-in heaters, radiators or vents; no storage hassles and no fan noise. No hot, exposed or moving parts and no maintenance. .
