Thermal insulating and sealing means for a safing slot in a curtain wall

A building construction having a wall construction defining an interior wall surface, which includes an interior panel extending over the interior surface thereof and at least one floor spatially disposed from the interior wall surface defining a safing slot extending between the interior wall surface of the interior panel and an outer edge of the floor, wherein the interior panel is a metal back pan, comprising a thermal insulating and sealing means for effectively thermally insulating and sealing of the safing slot, wherein the thermal insulating and sealing means comprises:

• i) a primary insulation means of thermally resistant material positioned in the safing slot defined between the outer edge of the floor and the interior panel to thermally insulate and seal the safing slot, wherein the primary insulation means includes:
• a) an inner primary end surface positionable in abutment with respect to the outer edge of the floor for sealing thereadjacent,
• b) an outer primary end surface positionable in abutment with respect to the interior panel, and
• c) an upper primary facing surface extending between the inner primary end surface and the outer primary end surface and facing upwardly therebetween;
• ii) a supplemental insulation means of thermally resistant material attached to the interior panel of a wall at a position immediately above the primary insulation means and in abutment with respect to the upper primary facing surface thereof;
• iii) a supplemental attachment means for attaching of the supplemental insulation means with respect to the interior panel positioned thereadjacent;
• and
• iv) an outer fire retardant coating positioned across the primary insulation means and the adjacent portions of the interior wall surface of the interior panel and the floor located thereadjacent,
• wherein the supplemental attachment means comprises at least one pin or screw means extending through the supplemental insulation means and being attached to the interior wall surface of the interior panel, and at least one nut or washer means secured to the at least one pin or screw means adjacent the supplemental insulation means at a position oppositely disposed from the interior wall surface of the interior panel for facilitating attachment of the supplemental insulation means with respect to the interior wall surface of the interior panel immediately above the primary insulation means and in abutment with respect to the upper primary facing surface thereof, and
• wherein the supplemental insulation means of thermally resistant material is attached to the interior panel at a position immediately above the primary insulation means and in abutment with respect to the upper primary facing surface thereof and wherein the supplemental insulation means comprises a band of supplemental insulation continuous horizontal along and in abutment with respect to the upper primary facing surface of the primary insulation means.

A thermal insulating and sealing system configured to thermally insulate and seal a safing slot within a building construction having a wall construction defining an interior wall surface, which includes an interior panel extending over the interior surface thereof and at least one floor spatially disposed from the interior wall surface defining the safing slot extending between the interior wall surface of the interior panel and an outer edge of the floor, wherein the interior panel is a metal back pan, the system comprising:

• i) a primary insulation of thermally resistant material positioned in the safing slot, wherein the primary insulation includes:
• a) an inner primary end surface positionable in abutment with respect to the outer edge of the floor for sealing thereadjacent,
• b) an outer primary end surface positionable in abutment with respect to the interior panel, and
• c) an upper primary facing surface extending between the inner primary end surface and the outer primary end surface and facing upwardly therebetween;
• ii) a supplemental insulation of thermally resistant material attached to the interior panel of a wall at a position immediately above the primary insulation and in abutment with respect to the upper primary facing surface thereof;
• and
• iii) a supplemental attachment for attaching of the supplemental insulation with respect to the interior panel positioned thereadjacent.
