HEAT-INSULATING PROFILE AND MANUFACTURE THEREOF

PROBLEM TO BE SOLVED: To manufacture profiles having heat-insulating structure easily by arranging one side of a heat-insulating member while being crossed over one frame member and the other frame member and fixing both frame members. SOLUTION: The upper end section 9b of the indoor-side member 31 of the profiles is exposed to the indoor side, and heat in an indoor section is transmitted to the profiles. The lower end section 9a of the underfloor-side member 33 of the profiles is exposed into an underfloor space, and heat in the underfloor space is transmitted on the side lower than an airtight material 39 holding a section between a cover body 11 and a frame material 8 in an airtight manner. Since the profiles are separated into the indoor-side member 31 and the indoor- side member 33 through a groove 29, however, the heat conduction of both indoor-side members is interrupted by the groove 29. Consequently, heat transfer in the indoor section and the underfloor space is prevented. As a result, indoor heating and cooling effects are improved. A heat-insulating function is also obtained simultaneously by interposing the airtight material 39 in the groove 29, and heat transfer due to radiant heat, the convection of air, etc., is also hindered. Accordingly, manufacture is facilitated, and the strength of the heat- insulating profiles can be increased.
