Long-lasting exterior insulation
  The term “externally insulated RC” is used only in Japan.

Insulating materials are of course applied to the exterior surfaces of walls in other countries, as well, but overseas there is no standard term similar to the Japanese “externally insulated RC” to refer to this specific type of concrete insulating method. The main features of externally insulated RC are:
1. superior material quality that can withstand the severe temperature changes and freezing/thawing that occur in Japan’s climate; and
2. superior resistance to carbonation due to acid rain.
