Dynamic, fire-resistance-rated thermally insulating and sealing system having a F-Rating of a min. of 120 min for use with curtain wall structures

A dynamic, thermally insulating and sealing system for effectively thermally insulating and sealing of a safing slot within a building construction having a curtain wall construction defined by an interior wall surface, including at least one vertical framing member and at least one horizontal framing member, 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 at least one floor, the dynamic, thermally insulating and sealing system comprising:

• a tubular sealing element comprising a thermally resistant flexible foam material for insulating and sealing, the tubular sealing element positioned in the safing slot, wherein the tubular sealing element comprises:
• a) a bottom side cover having at least two side surfaces, wherein at least a portion of both of the at least two side surfaces overlap with at least a portion of the thermally resistant flexible foam material;
• b) a top side cover;
• whereby the top side cover is connected at two positions, spatially disposed from each other, to the bottom side cover;
• and whereby the bottom side cover and the top side cover surround the thermally resistant flexible foam material;
• c) a first connection area for attaching the tubular sealing element to the interior wall surface of the curtain wall construction, wherein the bottom side cover and the top side cover overlap over at least a portion of the first connection area;
• and
• d) a second connection area for attaching the tubular sealing element to the outer edge of the at least one floor.
