Heating cables
Indoor heating cables are used for a variety of applications, including indoor comfort floor heating and total heating, both for small houses as well as large commercial buildings. Heating cables are mostly used in connection with new build or larger renovation projects. Heating cables used in floor constructions are serial resistive cables, preferably twin conductor for easier installation. A range of single conductor cables are also available.
Check our application manuals via the links below to get the best recommendations for design and installation of floor heating systems.

if (isSmallPicture) { ; } else if (isBigColumns) { } else { }Heating Mats
The heating mats are used for installation in a thin layer of tile adhesive, self-leveling mixture, or similar. The standard minimum thickness of the floor layer is 5-8 mm while the thickness of electric heating mat is 3–4.5 mm. This minimizes the floor level increase. Electric heating mats consist of a thin cable securely fixed on self-adhesive glass-fiber mesh, usually of 50 cm width. Thin heating mats are manufactured as ready-made heating sections with a specific area (i.e. 0.5, 1, 1.5 … 12 m²) including a power supply cable (cold lead) and hermetically sealed connections.
