Description

  The present invention relates to a heat insulating exterior material and exterior structure useful as a roofing material and an outer wall material.

Conventionally, in order to obtain heat insulation performance in a roof structure called “folded plate”, a “double folded plate” having a structure in which metal folded plates are laid double and a heat insulating layer is provided inside has been proposed. And it is performed by interposing glass wool and a foamed resin board as a means to provide a heat insulation layer. However, as described above, the laying of the glass wool and the board must be individually laid with the lower exterior material, the heat insulating material, and the upper exterior material, and the workability is poor, and the heat insulating material is lightweight. Therefore, there is a risk of scattering and damage during work. Furthermore, since the exterior material is laid twice, there is a problem that the cost is inevitably increased. On the other hand, as other specifications, there are ones that are integrated by self-adhesive force at the time of foaming, or a molded heat insulating material is integrated with an adhesive or the like (see Patent Document 1).
However, the heat insulating exterior material integrated as described above has the following problems. Because the heat insulating material is integrated with the heat insulating material with the self-adhesive force or adhesive of the heat insulating material, for example, even if you try to recycle the heat insulating heat insulating material that has become unnecessary due to replacement, Unless the insulation is separated, it cannot be recycled as it is and cannot effectively use resources. However, recycling the metal exterior material and the synthetic resin heat insulating material, etc., is not practical because it takes too much time and is uneconomical. .
