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.

The round profile, low height (only 3.5 mm) and robust construction ensure a fast, simple, and safe installation, perfect for renovating existing floors. The cold lead has solid conductors ensuring fast installation. A clearly visible connection avoids accidentally installing the heated cable in the wall.
