Selecting the required film or film for a room is a simple three step process.

Check Floor Surface

Components of an LH-K system

LH-K heating films are specifically designed for installation under laminate and engineered wood floors.  They should not be used with other floor surfaces.

If there is any doubt about the suitability of any given floor surface for use with underfloor heating, confirmation should be sought from the flooring supplier.

Select the correct LH-K kit

The objective is generally to cover as high a percentage of the free floor area as possible.  The free floor area is defined as the floor area not occupied by permanent fixtures such as kitchen cabinets and wardrobes.

Select insulation/underlay and vapour barrier

VB Vapour Barrier

VB Vapour Barrier

LH films must be installed onto a layer of I-Board-6 insulation/underlay and below a layer of VB vapour barrier.  Heating film, insulation/underlay and vapour barrier must be held in place with LHT high adhesion tape.  Both I-Board-6 and VB must cover the entire floor area not just the heated area.

I-Board-6 is lightweight and easily cut to shape.

Controls

Underfloor heating cables must be thermostatically controlled.  BN Thermic offers a wide range of thermostats from a simple manual device to the latest smart technology.
