Description

The present invention relates to a method of constructing a heat insulating material. That is, it relates to a method of constructing a heat insulating material, which is less likely to cause damage such as cracks.

<< Technical background and prior art >>
Insulation is applied to buildings, freight vehicles, cooler boxes, and various other walls to insulate them from the outside air. It is installed to keep the high temperature part warm and the low temperature part cold.
FIG. 2 (1) shows a conventional representative example in which the heat insulating material 1 is applied to the wall plate of a building. In the figure, the heat insulating material 1 is made of foamed plastic 2 having a low thermal conductivity, and is interposed between the surrounding wall frames (pillars and beams) A along the inner and outer wall plates.

Examples of such a heat insulating material 1 include those shown in the following Patent Document 1.
Japanese Unexamined Patent Publication No. 2001-165387

By the way, regarding the conventional heat insulating material 1, the following problems have been pointed out as problems. It has been pointed out that the conventional heat insulating material 1 is prone to breakage such as cracks and often cannot maintain heat insulating properties.
That is, the foamed plastic 2 of the heat insulating material 1 deteriorated due to aged use, an earthquake, or the like, and damage such as cracks, holes, tears, cracks, cracks, and collapses was likely to occur.
In addition, there were many animal damages in which the heat insulating material 1 foamed plastic 2 was torn off by small animals such as weasels, palm civets, and mice, and cracks and other damages were likely to occur from this aspect as well.
Therefore, the conventional heat insulating material 1 has a short period in which the heat insulating property can be maintained, and the replacement frequency is high. In many cases, cracks or other damages in the heat insulating material 1 cannot be confirmed from the outside appearance of the wall plate. In that case, the wall plate is widely broken and the heat insulating material 1 is replaced.
It has also been pointed out that these will increase the cost burden.
