Thermal insulation
The insulation levels of a floor will affect both the performance & running costs of floor heating system.
The thermal insulation reflects the heat upwards into the floor tile instead of allowing heat to penetrate into the
subfloor and keeps the floor warmer for longer time. While installing the floor heating system, user should install
adequate thermal insulation below it. In cases where the floor heating system is being installed over large areas,
insulation boards will greatly reduce warm-up times & running costs.
When floor heating systems are installed on a concrete slab, we strongly recommend adding a layer of insulation
to the slab prior to installing the heating cables. Adding insulation on top of the concrete slab or board, and
beneath any floor heating system will allow a greater percentage of heat generated to transfer to the flooring
surface.
The heating cable system is approved for the following types of installation:
• On a subfloor
Important: The subfloor material in contact with the heating cable must be able to withstand
a temperature of at least 90 °C (194 °F).
