<p>PURPOSE:To prevent the flow of moxious gas into a room and to promote heat insulation efficiency by forming a large number of hollow hoes inside an interior material formed of cement system panel materials, and forming a large number of channels in single side of the interior material. CONSTITUTION:A plurality of rectangular hole shaped hollow holes 3 are formed in an interior material 2 of cement system panel materials, and a plurality of recessed channel-shaped channels 4 are formed in single side of the interior material 2. Accordingly, air in a room M heated by a heating appliance N, etc., in the room M enters into the hollow hoes 3 of the interior material 2 through ventilation ports 11, passing through the hollow holes 3 to flow down, making a turn at the lower part thereof, passing through the channels 4 to raise, and entering into a loft space R to exhaust through a fan 12 to the outside. When heated air in the room passes through the hollow holes 3, heat of air is stored arount the hollow holes 3. When air in the room passes through the hollow holes 3, humidity in air is abaorbed into the interior material 2. According to the constitution, living amenity in the room is promoted.</p> |
