||FinnKit is designed to be used as floor heating in small and cramped areas and it should be installed to thin layer of levelling compound. The cable is round with a diameter of only 3.5 mm. The small diameter enables the use of less casting material during installation. FinnKit may be used together with a wide range of flooring material, but the cable should always be laid upon fireproof material and have to be covered with levelling compound. The sizes of FinnKit cover an area of 0,7–9,4 m².
