PROBLEM TO BE SOLVED: To provide a heat insulating sash for improving a design (an outward appearance) of an indoor side angle part 10 of a resin frame. SOLUTION: This heat insulating sash frame of a composite structure forms the outdoor side of a metallic frame, and forms the indoor side of a resin frame. The angle part 10 formed in the resin frame is formed of a positioning piece 11 abutting on an outdoor side end surface of an architrave 22 arranged on an inner peripheral surface of an opening part A of a building frame, and an installing piece 12 screw-fastened to an inner surface of the architrave 22. An indoor side engaging part 25 is formed in an indoor side face surface part of the installing piece of the angle part. An outdoor side engaging part 26 is formed near the outdoor side of a depth surface on the sash opening side of the installing piece 12. Resin cover materials 23a, 23b, and 23c for hiding a head of an installing machine screw to the building frame are engaged with and installed in both engaging parts. COPYRIGHT: (C)2005,JPO&NCIPI
