Abstract

Described is a construction and parts of the construction for effectively thermally and acoustically insulating and sealing of a safing slot (1) between a floor (6) of a building and an exterior wall construction wherein the exterior wall construction comprises a curtain wall configuration (2) utilizing an interior panel module design. In particular, the thermal insulating and sealing system comprises a first element (7) comprising a top framing component (8) having an interior wall surface (13) and an opening, positioned substantially in the height of the floor (6), wherein the top framing component (8) is located on top of the interior wall surface (3) of the spandrel panel (7), and a second element (9) comprised of a thermally resistant and/or air tight material for insulating, positioned at least partially in the top framing component (8) of the first element (7), wherein the second element (9) includes an inner end surface (10) positionable in abutment with respect to the outer edge (11) of the floor (6) for sealing thereadjacent, outer end surface (12) positionable in abutment with respect the interior wall surface (13) of the top framing component (8), a lower facing surface (14) extending between the inner end surface (10) and the outer end surface (12) and facing downwardly therebetween, and an upper facing surface (15) extending between the inner end surface (10) and the outer end surface (12) and facing upwardly therebetween.
