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

A building construction having a curtain wall construction defined by an interior wall surface including one or more framing members and at least one floor spatially disposed from the interior wall surface of the curtain wall construction defining a safing slot extending between the interior wall surface of the curtain wall construction and an outer edge of the floor, comprising a dynamic, thermally insulating and sealing system for effectively thermally insulating and sealing of the safing slot, wherein the dynamic, thermally insulating and sealing system comprises:

• i) a first element comprising a non-combustible material for receiving a thermally resistant material for insulating, wherein the first element has a cavity-shaped profile, comprising:
• a) a web section having opposing edges and an inner and an outer surface;
• b) a pair of outwardly extending side sections connected to the web section, wherein each side section has an outer and an inner surface, a proximal end and a distal end, wherein the proximal end of each side section is connected to one of the opposing edges of the web section, and wherein the side sections are substantially parallel and confront each other;
• and
• c) at least one supplemental element for attaching of the first element with respect to a bottom side of the horizontal framing member of the curtain wall construction,
• ii) a second element comprising a thermally resistant material for insulating positioned in the first element, wherein the second element includes:
• a) an outer primary end surface positionable in abutment with respect to the inner surface of the web section of the first element;
• b) an inner primary end surface positionable spatially disposed from the outer edge of the floor for sealing thereadjacent;
• and
• c) a lower primary and an upper primary surface extending between the proximal and distal ends of the pair of the outwardly extending sidewalls of the first element and in abutment with respect to the inner surface of each of the outwardly extending side sections,
• iii) a third element comprising a thermally resistant material for insulating positioned in the safing slot, wherein the third element includes:
• a) an inner primary end surface in abutment with respect to the outer edge of the floor for sealing thereadjacent;
• b) an outer primary end surface positioned in abutment with respect to the inner primary end surface of the second element and spatially disposed from the inner surface of the web section of the first element;
• and
• c) a lower primary and an upper primary surface extending between the distal end of each of the outwardly extending sidewalk of the first element and the outer edge of the floor,
• iv) a fourth element for supporting and attaching the first element with respect to an inner facing side of the vertical framing member of the curtain wall construction, wherein the fourth element has a substantially L-shaped profile and includes elements for attachment, and wherein the fourth element comprises a metal, and
• vi) an outer fire retardant coating positioned across the first element and the adjacent portions of the interior framing member of the curtain wall construction and the floor located thereadjacent.
