あつた。 However, with this construction method, it is difficult to provide heat insulating material around window frames or door frames, for example, due to the construction process. This is because window frames and other items are installed after concrete frame work, and a space (gap) is required between the frame and the frame for installation, and the area around the window frame or door is The reason for this is that it was difficult to fill this part with plate-shaped heat insulating material because of the complicated nature of the structure, and it was often the case that this part was not filled with anything.
If areas without insulation such as around window frames or door frames (hereinafter referred to as insulation defects) are left as they are, a large amount of heat will escape from these insulation defects, causing The problem was that the heat insulation performance of the

用いられているため断熱性能に劣るという問題点
があつた。 For this reason, attempts have been made to provide some kind of heat insulating material to the above-mentioned heat insulating defective portion. For example, one such attempt is to fill the insulation defect with mortar, but since mortar itself has a high thermal conductivity, it is difficult to provide good insulation performance. In addition, a method of filling insulation defects with an insulation material made by mixing bead-shaped foamed plastics such as expanded polystyrene with mortar is also being considered, but this method still has the problem of poor insulation performance due to the large amount of mortar used. It was hot.

点もあつた。 For this reason, a method has been proposed in which foamable urethane is poured into the insulation defect and foam is generated in the defect. However, with this method, it is not easy to control the foaming of urethane, and it may flow out from the insulation defect and adhere to the surrounding area.
There were major problems in that it took time and effort to remove this deposit, and it also took time and effort to scrape off the foamed portion that protruded from the insulation defect.
Another problem was that foamable urethane was expensive.
