Environ IIJ is a new micro-thin radiant heating system designed for installation under carpeting and laminate wooden floors. It is intended for combating cold rooms caused by zone heating problems. The multiple sizes of the heating mat, all measuring 1/16 inch in height, are composed of looped heating coils sandwiched between four layers of foil. The leads from each mat are connected to a 120-V electrical circuit and a seven-day programmable thermostat.
