STN under floor heating may be installed directly under any type of coating:
In this case, the floor elevation will be increased merely by the height of the heating element (2-4 mm).
Heating systems are easy to install. When installing the system, you do not need to coat it with a cap. These extremely thin and flexible systems may be installed on existing flat surface.
When installing STN under floor heating in premises with high level of moisture, please always place a metal grid on the heating system for the purposes of electrical safety.
