Description

  The present invention relates to a novel outer heat insulating decorative finishing method and structure.

In recent years, in buildings such as commercial facilities, apartment houses, and detached houses, there has been a lot of efforts to save energy and resources by saving air conditioning costs through high insulation and high airtightness. .
In general, in a building not designed for heat insulation, indoor heat escapes from the roof, floor, window, wall, and the like during heating in the winter, and outdoor heat enters from these parts during cooling in the summer. It is said that about one third of such heat loss is caused by the wall surface. Therefore, in order to realize resource saving of buildings, it is indispensable to increase the heat insulation of the outer wall that separates the room from the outside. In recent years, various wall surface structures in which a heat insulating material is provided on the outer wall surface have been proposed. As an example, a wall surface structure in which a heat insulating material layer made of polystyrene foam, phenol foam, or the like is provided on the outer wall surface of a building and a sheet material or the like is provided on the upper layer is known (for example, Patent Document 1).
However, the sheet materials described in Patent Document 1 and the like are mostly flat and monochromatic, and are currently poor in design.
