PROBLEM TO BE SOLVED: To mount a curtain wall having a window portion that can control heat beside a window in a short time and prevent an indoor space from getting reduced. SOLUTION: An outdoor side glass 11 and an indoor sliding door 12 are mounted in a sill 8 forming the window portion B of a curtain wall unit, and a blind 14 is mounted in a space portion 13 between them. The clearance between the top 5a of a lower rail 5 and the lower ends of the first sliding door 50 and the second sliding door 51 is made an air intake 22, and an exhaust opening 23 is formed in an intermediate horizontal material 5, thereby making the window portion B control heat besides a window and mounting a curtain wall in a short time only by mounting a curtain wall unit 1 to the body of a building. As the indoor sliding door 12 does not project into the interior, the indoor space is not decreased.
