摘要

PROBLEM TO BE SOLVED: To inexpensively and efficiently remove a material causing the generation of a harmful gas such as formaldehyde from a floor material by using a floor heating equipment. ;SOLUTION: A gas capturing material 8 and a heat insulating material 10 are successively provided on the indoor 2 side of the floor material 6 provided in the upper side of the floor heating equipment 4 so as to cover the floor material 6. After that, the floor material 6 is heated to be kept at a high temp. by the floor heating equipment 4 to accelerate the generation of the harmful gas from the floor material 6. The harmful gas such as formaldehyde generated by heating is captured by the gas capturing material 8 without making to flow out in the indoor 2 to remove the harmful gas generation causing material contained in the floor material 6.;COPYRIGHT: (C)1999,JPO
