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 top framing component having an interior wall surface and an opening, positioned substantially in the height of the floor, wherein the top framing component is located on top of the interior wall surface of the spandrel panel, and a second element comprised of a thermally resistant and/or air tight material for insulating, positioned at least partially in the top framing component 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 thereadjacent, outer end surface positionable in abutment with respect the interior wall surface of the top framing component, 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

1 - 22 . (canceled)

23 : A sealing system, comprising:
a compartment comprising at least two sides; a cover over an interior space of the compartment; and a sealing material disposed in the interior space of the compartment, wherein the sealing material is in a compressed state in the interior space of the compartment when the cover is closed and expands to an uncompressed state when the cover is opened.

24 : The sealing system of claim 23 , wherein the sealing material expands a predetermined distance to occupy a space outside of the compartment when in the uncompressed state.

25 : The sealing system of claim 24 , wherein:
the sealing system is configured to be installed in a curtain wall construction; and the space outside the compartment comprises a safing slot adjacent a floor in an installed state in the curtain wall construction.

26 : The sealing system of claim 23 , wherein the cover is coupled to forward edges of the at least two sides.

27 : The sealing system of claim 26 , wherein the sealing material expands through a hole in the cover when the cover is open.

28 : The sealing system of claim 27 , wherein the cover comprises one or more perforations configured to form the hole when the one or more perforations are torn.

29 : The sealing system of claim 28 , wherein the hole is formed while the cover is still coupled to the compartment.

30 : The sealing system of claim 23 , wherein the compartment and cover comprise different materials.

31 : The sealing system of claim 23 , wherein the cover comprises a plastic material or a metal foil.

32 : The sealing system of claim 23 , wherein the sealing material includes a fire-resistant material.

33 : The sealing system of claim 32 , wherein the sealing system comprises a foam.

34 : The sealing system of claim 23 , wherein the compartment comprises a back pan coupled to rear edges of the at least two sides.

35 : The sealing system of claim 23 , wherein the sealing material has substantially a block configuration.

36 : The sealing system of claim 23 , wherein the compartment includes one or more ledges configured to mount the compartment.

37 : A spandrel panel, comprising:
a sealing system as recited in claim 23 .
