Abstract

The present invention relates to a heating element, which is integrated into the construction material. Integration of the heating element according to the present invention into the construction material limits space needed for the heating system. In addition, the used heating element provides reduced power consumption compared to conventional technologies. A construction element according to the present invention comprises a construction material, a heating element comprising a foil comprising a PTC composition layer or a PTC composition layer, at least one adhesive layer, a substrate and a connector, wherein said heating element is embedded between said construction material and said substrate, and wherein said PTC layer comprises a semi-crystalline material, at least one binder and an electronically conductive material.
