FLOOR HEATING SYSTEM MAKING USE OF COMPOSITE PANEL

PROBLEM TO BE SOLVED: To provide a floor heating system excellent in workability for the improvement of the floor heating system in a house laying a composite panel as a floor construction. SOLUTION: In a method forming the floor construction by laying the composite panel having a predetermined shaped plate material (a) and providing a plurality of rib members (b) and a thermal insulating material (c) at the back thereof on a sleeper of a building, the composite panel consists of a standard composite panel P having each rib member (b) making the height from the upper surface of the sleeper 6 to the surface of the plate material (a) as the standard height and an auxiliary composite panel having the rib member (b) making the plate material (a) lower by a predetermined uneven step and being supported on the sleeper 6 in a state to be supported by the sleeper 6, the method forming the floor construction is so constituted that a floor heating partition laying the auxiliary composite panel P1 on the sleeper 6 of the building and a non-floor heating partition laying the standard composite panel P are formed, the surface of a floor heating member 10 formed by laminating the floor heating member 10 having the thickness by an uneven step on the auxiliary composite panel P1 and the surface of the standard composite panel P are made flush with each other and that floor boards 18, etc. are laid on these composite panels to complete the floor construction.
