DEW CONDENSATION PREVENTIVE WALL-SURFACE STRUCTURE

PURPOSE:To prevent the dew condensation of a wall surface completely by covering the whole surface of a backing wall surface with a specified heat- insulating material without a break. CONSTITUTION:A woody board 3 in approximately 10mm thickness is laminated on a foamed resin material 2 in approximately 40mm width, approximately 3000-4000mm length and approximately 10mm thickness, thus forming a composite board 4. The composite board 4 is installed to a backing wall surface 1 in the vertical direction or the horizontal direction, and a dew condensation preventive board 5 in proper thickness is laid around the composite board 4 without a clearance. The surfaces of the composite board 4 and dew condensation preventive board 5 are covered with a finished wall surface 6. Accordingly, the all surfaces of the backing wall surface 1 are covered with a material for preventing dew condensation, thus forming a heat-insulated layer having no clearance.
