The system does not require covering with any self-levelling compound or tile adhesive and your flooring can be laid directly on top of the heating mats themselves. The heating cable is fully earthed for safety, the aluminium layer above it is purely for heat dissipation. This allows the underlaminate system to be safely used in virtually any type of room including bathrooms and, unlike carbon films and similar systems, you do not have the extra cost of installing earthing grids above your heating system to ensure it is safely earthed.The system is entirely manufactured in the UK ensuring a consistently high quality product and a minimum of travel miles between manufacture and installation. The Underlaminate System should be controlled by Heat Mat's innovative BEAB approved thermostats, one for each room, to ensure it is controlled in the most energy efficient way. Please note you must always control the system with a floor sensor.As with any underfloor heating system beneath wooden floors, care should be taken not to place any heating beneath areas where there will be a thermal block on top of the floor covering. Furniture without air gaps beneath them or large beanbags prevent the heat escaping from the floor and can cause the system to overheat in extreme circumstances. * Different Floor Construction Options * How to install your Heating Mats * Technical Specification - all you need to know!Follow this Link to View and Buy the Underlaminate System Online
