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 tubular sealing element for insulating and sealing, the tubular sealing element comprising:

• a thermally resistant flexible foam material;
• a bottom side cover:
• a top side cover, connected at two positions, spatially disposed from each other, to the bottom side cover, wherein the bottom side cover and the top side cover together surround the thermally resistant flexible foam material;
• a first connection area configured for attaching the tubular sealing element to an interior wall surface of a curtain wall construction;
• a second connection area configured for attaching the tubular sealing element to an outer edge of a floor;
• at least one adhesive layer configured for fixing the tubular sealing element to the curtain wall construction;
• and
• wherein the bottom side cover and the top side cover are configured to allow compression of the thermally resistant flexible foam material between the interior wall surface and the outer edge of the floor during installation.
