Abstract

Described is a construction and parts of the construction for effectively thermally and acoustically insulating and sealing of a safing slot between a floor of a building and an exterior wall construction wherein the exterior wall construction comprises a curtain wall configuration utilizing an interior panel module design. In particular, the thermal insulating and sealing system comprises a first element comprising a cavity having an interior wall surface and an opening, positioned substantially in the height of the floor, wherein the cavity is located in the spandrel area of the interior wall surface, and a second element comprised of a thermally resistant and/or air tight material for insulating, positioned at least partially in the cavity of the first element, wherein the second element includes an inner end surface positionable in abutment with respect to the outer edge of the floor for sealing there adjacent, outer end surface positionable in abutment with respect the interior wall surface of the cavity, a lower facing surface extending between the inner end surface and the outer end surface and facing downwardly therebetween, and an upper facing surface extending between the inner end surface and the outer end surface and facing upwardly therebetween.

First claim

The invention claimed is:

1. A building construction having a curtain wall construction defined by an interior wall surface comprising framing members and at least one floor spatially disposed from the interior wall surface of the curtain wall construction defining the safing slot extending between the interior wall surface of the curtain wall construction and an outer edge of the floor, comprising a thermally insulating and sealing system for effectively thermally insulating and sealing of the safing slot, wherein the thermal insulating and sealing system comprises: i) a first element comprising a cavity, which is a compartment having a base and at least two sides, configured to be positioned substantially at a height of the floor, within the spandrel area of the interior wall surface, the cavity comprising an opening that opposes the base and has an orientation facing an interior of a building and aligned with the safing slot in an installed state of the building construction in or on the building, wherein the cavity has a width less than a width of the spandrel area between the framing members of the curtain wall construction in the installed state, a central axis of the spandrel area between the framing members passing through the cavity and an alignment axis passing through the base of the cavity and the framing members in the installed state, and
ii) a second element comprising a first thermally resistant and/or air tight insulating material positioned at least partially in the cavity of the first element in the installed state, wherein the second element comprises
a) an inner end surface configured to be in abutment with the outer edge of the floor for sealing thereadjacent,
b) an outer end surface configured to be in abutment with the interior wall surface of the cavity,
c) a lower facing surface extending between the inner end surface and the outer end surface and facing downwardly therebetween, and
d) an upper facing surface extending between the inner end surface and the outer end surface and facing upwardly there between, and

iii) a connecting third element comprising a second thermally resistant and/or air tight insulating material positioned in front of the vertical framing member and in abutment with respect to the second element in the installed state, wherein the first thermally resistant and/or air tight insulating material projects beyond the first element in the direction of the at least one floor and passes through the opening and extends a distance from the spandrel panel sufficient to occupy the safing slot and contacting the floor in the installed state, wherein the cavity is made from rigid material, and wherein the thermally resistant and/or air tight insulating material comprises a thermally resistant and/or air tight flexible mineral wool material, rubber-like material or a foam.
