PROBLEM TO BE SOLVED: To provide a building member for forming an air circuit, by which the efficiency of energy conservation is improved as an air-cycle residence, production cost is reduced and the execution of works is facilitated. SOLUTION: In a heat-insulating material formed of a plate-shaped material having heat-insulating properties, mounting edges 4 to column members are formed at both end sections while the rear side is bulged so as to be abutted against the rear of an external facing material or an interior finish material at a central section, and a recessed section 5 for forming the circuit continued to at least one vertical direction is formed on the front side. Recessed sections 6 for the execution of works, from which the rears of the mounting edges 4 are exposed, are continued and formed in the vertical direction respectively among the mounting edges 4 and the recessed section 5 for forming the circuit. |
