Patent ID: 7856775

Claim:
A building construction having a wall construction defining an interior wall surface, which includes an interior panel defining an interior panel surface and at least one floor defining an outer edge thereon spatially disposed from the interior wall surface to define a safing slot extending between the interior surface of the interior panel and the outer edge of the floor, wherein the improvement comprises a thermal insulating and sealing means for effectively thermally insulating and sealing of the safing slot comprising: A. a primary insulation of thermally resistant material positioned in the safing slot defined between the outer edge of the floor and the interior panel extending over the interior surface of the wall construction to thermally insulate and seal the safing slot defined therebetween, said primary insulation including; (1) an inner primary end surface positioned in abutment with the outer edge of the floor for sealing thereadjacent; (2) an outer primary end surface positioned in abutment with the interior panel extending over the interior surface of the wall construction; (3) a lower primary facing surface extending between said inner primary end surface and said outer primary end surface and facing downwardly therebetween; B. a supplemental insulation of thermally resistant material attached to the interior panel of the wall at a position immediately below said primary insulation and in abutment with said lower primary facing surface thereof, said supplemental insulation being movable along with the interior panel of the wall to maintain insulation in abutment therewith and to facilitate maintaining complete insulation across the safing slot; and C. a supplemental attachment means for attaching of said supplemental insulation to the interior panel positioned thereadjacent to facilitate movement of said supplemental insulation along with the interior panel of the wall and maintain insulation thereadjacent for extending completely across the safing slot.
