Green cable surface of 2 W consists of two twisted/sites and paired heating elements covered in copolymer. It uses ultra-resistant and high-performance components to provide perfect comfort, peace of mind, a healthy environment and real energy savings. It can be used in all rooms, regardless of their shape and size. Designed for dry and wet spaces, it is easy to install thanks to the UNIVERSAL SNAP-IN GAGES™ and to the fact that it is not necessary to return the cable to the thermostat. 2 W optimizes radiant heat and ensures that it spreads evenly over all installation surfaces and under all floor coverings due to its 2 inch or 3 inch spacing (5 cm or 7.6 cm).
