Next, the difference of the heat insulation performance of the opening part building material of this invention by the attachment position of the flame | frame 2 is demonstrated based on Fig.4 (a)-(d) and Fig.5 (a)-(c).
4 (a) to 4 (d) and FIGS. 5 (a) to 5 (c) having different mounting positions of the frame 2, heat flow calculation is performed, and each is generated between the opening building material and the frame 3. The values of heat loss Ψ and total heat flow were calculated. FIGS. 4A to 4D are opening building materials that do not have the heat insulating space 10, and FIGS. 5A to 5C have the heat insulating space 10 on the outdoor side of the housing attachment piece 21. Opening building material. 4 (a) to 4 (d) and FIGS. 5 (a) to 5 (c), the width of the cover portion 22 of the frame 2 differs depending on the length between the housing attachment piece 21 and the outer wall 7. In addition, the structure of 1st embodiment shown in FIG.1 and FIG.2 is a structure substantially the same as FIG. 5 (a).
The mounting position of each frame 2 will be described in detail. FIG. 4A shows the frame 2 in a so-called semi-external position as in the conventional opening construction material shown in FIG. The piece 21 is fixed to the outdoor-side finding surface of the housing 3. 4 (b) and 5 (a), the frame attachment piece 21 of the frame 2 is fixed at a position that is about a quarter of the width in the expected direction of the frame 3 from the outdoor end of the frame 3. . 4 (c) and 5 (b), the frame attachment piece 21 of the frame 2 is fixed at a position that is approximately one half of the width of the frame 3 in the expected direction. 4 (d) and 5 (c), the frame attachment piece 21 of the frame 2 is fixed at a position that is about three-quarters of the width in the expected direction of the frame 3 from the outdoor end of the frame 3. .
Next, the result of the heat flow calculation will be described. First, by comparing FIGS. 5 (a) to 5 (c) and FIGS. 4 (b) to 4 (d), when the difference in heat insulation performance due to the presence or absence of the heat insulation space 10 is compared, the heat insulation space is the same at the same mounting position. 5 (a) to (c) having 10 has a smaller value of the heat loss Ψ than that of FIGS. 4 (b) to (d) having no heat insulation space 10. Furthermore, when the difference in the heat insulation performance depending on the mounting position of the frame 2 is compared, the value of the heat loss Ψ at the semi-external position in FIG. 4A is the largest and the value of the heat loss Ψ is small in FIG. ) (C) and FIGS. 5 (a) and 5 (b). Therefore, the structure of FIG. 5A and FIG. 5B in which the heat insulating space 10 is provided and the frame 2 is attached between the outdoor side end of the housing 3 and the approximate center in the expectation direction is excellent in heat insulating performance. 5 (a) and 5 (b), no significant difference was found in the values of heat loss Ψ and total heat flow, but considering the amount of solar radiation to be inserted into the room through the glass panel 5, the frame 2 is located further outside. The attachment position of FIG. 5A to which the is attached is more desirable than the attachment position of FIG.

According to the opening part building material of 1st embodiment comprised in this way, since the frame 2 has the housing attachment piece 21 and is attached to the indoor side rather than the waterproofing material 12 located in the indoor side of the outer wall 7, it is heat loss. Can be suppressed. And the heat insulation performance can be improved more by the heat insulation space 10 formed between the frame attaching piece 21 and the waterproof material 12 on the outer peripheral side of the frame 2.
As for the attachment position of the frame 2, it is desirable that the housing attachment piece 21 is on the indoor side of the waterproof material 12 located on the indoor side of the outer wall 7 and on the outdoor side from the approximate center of the housing 3 in the expected direction. This mounting position is optimal because heat loss can be reduced and the amount of solar radiation can be secured.
Furthermore, since the receiving materials 30 and 40 are attached to the outdoor side of the frame 2 and the receiving materials 30 and 40 are provided with the waterproofing material attaching portions 30c and 40c, the outer periphery of the waterproofing material attaching portions 30c and 40c is outer peripheral. The waterproof property around the opening can be improved by attaching the waterproofing material 12 over the outdoor-side opening member 6b on the side and the outdoor-side insulation surface of the outdoor-side heat insulating material 11a.
