Patent ID: 7805901

Claim:
A building construction comprising: a construction material including: a plate form structural face material; and a plate form vacuum insulation material laminated to said plate form structural face material so as to form an integral plate form construction material having a rear surface of said plate form vacuum insulation material facing a front surface of said plate form structural face material, said plate form vacuum insulation material including: a plurality of plate form core material sections; two flexible exterior covering materials covering said plate form core material sections, each of said exterior covering materials comprising a laminated film including a heat adhesion layer, a gas barrier layer, and a protection layer laminated in order from a side closest to said plate form core material sections, said exterior covering materials being configured to individually enclose said plate form core material sections within independent vacuum-enclosed spaces such that said plate form core material sections are aligned two-dimensionally without overlapping, each of said plate form core material sections being individually vacuum enclosed within a respective one of said independent vacuum-enclosed spaces, said exterior covering materials being heat-bonded to each other at heat adhesion areas, said heat adhesion areas being all areas of said exterior covering materials not sandwiching said plate form core material sections; a wooden base attached to said construction material by a plurality of fasteners driven through said vacuum insulation material, said wooden base and said construction material being arranged such that a front surface of said vacuum insulation material faces said wooden base; and an external wall finishing material fixed to said wooden base.
