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.

A split block assembly includes a backplate with an outwardly projecting mounting flange that mounts to a wall structure such that the flange is interposed between a siding panel and the wall structure. The backplate includes first and second plate segments rotatable with respect to each other between an open position, whereat the first plate segment is spaced from the second plate segment, and a closed position, whereat the plate segments abut and thereby cooperatively define a hole that receives therethrough a fixture. A living hinge system is integral with and rotatably joins the two plate segments. The living hinge system includes a first living hinge adjoining the first plate segment and bending on a first axis, a second living hinge adjoining the second plate segment and bending on a second axis oblique to the first axis, and a flap extending between and joining the two living hinges.
