The above-mentioned construction method has an effective aspect as a construction method for a heat insulating wall because it is possible to freely change the design at the construction site, but it is premised that all the construction work is carried out at the construction site. Therefore, it cannot be denied that the work becomes complicated. Also, it is necessary to carry out on-site grooving for attaching the furring strip. Furthermore, in order to arrange multiple heat insulating panels that are normally joined between main columns in the axial direction of the main columns, the panel joint becomes long in the vertical direction and the outer wall is kept to maintain the airtightness of that part. It is necessary to additionally attach a member such as a ventilation furring strip.

An object of the present invention is to eliminate the inconveniences of the conventional construction method as described above. More specifically, it is possible to freely change the specifications on the site while still working on the site. (EN) It is intended to provide a foamed resin heat insulating wall material in which the amount is minimized and a method of constructing a heat insulating wall using the same. Another object of the present invention is to provide a foamed resin heat insulation wall material capable of maintaining sufficient airtightness without attaching a member such as an outer wall ventilation furring to a joint portion of the foamed resin heat insulation wall material. And to provide a construction method therefor.
