PURPOSE: A construction method for the floor of a room is provided to emit much amount of far-infrared rays, which is good to human body, and to reduce fuel cost. CONSTITUTION: A construction method of a floor contains the steps of: spreading a waterproof vinyl sheet(11) on a cement floor layer(10), piling waste sheets(12) such as newspapers, leaflets, and corrugated cardboard, forming an interception layer by putting 2mm of veneer board(13), installing a heating pipe(14) on the veneer board, filing packing material(15) composed of feldspar particles on the heating pipe, mixing 75wt% of shattered feldspar small particles and 25wt% of cement on the packing material, and injecting water for kneading mortar(16) to be spread for 1.5-3cm of thickness. Therefore, a plaster layer is formed. Herein, the feldspar particles included in the mortar are heated by the heating pipe for emitting a large amount of far-infrared rays to neutralize the harmful ingredient of cement included in the mortar.
