Infrared heating foil
Panel or flat IR-heaters will commonly be installed behind the wall and will thus spread their rays equally. But they also need a longer preheating period and have, altogether, long wave rays. Moreover, these flat IR heating systems work exclusively with IR-C rays that do not go into the skin so deeply. A common type of this flat IR heater is the infrared mat.
Infrared mats (also referred to as IR-heating foils) are available in many variations, e.g. one of these consists of a polyester foil with aluminium heating element and thermostat.
They can be installed as wall, ceiling or floor heating behind the wall or clearly visible in the cabin. The heat will be spread within large areas and emitted via the wood of the cabin.
