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, comprising:

• 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, thereby defining a safing slot, extending between the interior wall surface of the curtain wall construction and an outer edge of the floor,
• wherein the curtain wall construction comprises 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 metal piece comprised of a non-combustible material for receiving a thermally resistant material for insulating, wherein the first metal piece has a cavity-shaped profile, the first metal piece 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 attachment for attaching of the first metal piece with respect to a bottom side of the horizontal framing member of the curtain wall construction,
• (ii) a first thermally resistant material for insulating, positioned in the first metal piece, wherein the first thermally resistant material includes:
• (a) an outer primary end surface positioned in abutment with respect to the inner surface of the web section of the first metal piece;
• (b) an inner primary end surface positioned spatially disposed from the outer edge of the floor for sealing thereadjacent;
• and
• (c) a lower primary surface and an upper primary surface extending between the proximal and distal ends of the pair of the outwardly extending sidewalls of the first metal piece and in abutment with respect to the inner surface of each of the outwardly extending side sections,
• (iii) a second thermally resistant material for insulating, positioned in the safing slot, wherein the second thermally resistant material includes:
• (a) an inner primary end surface positioned 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 first thermally resistant material and spatially disposed from the inner surface of the web section of the first metal piece;
• and
• (c) a lower primary surface and an upper primary surface extending between the distal end of each of the outwardly extending sidewalls of the first metal piece and the outer edge of the floor,
• (iv) a side connection for supporting and attaching the first metal piece with respect to an inner facing side of the vertical framing member of the curtain wall construction, wherein the side connection has a substantially L-shaped profile and includes at least one screw for attachment,
• wherein the first metal piece and the side connection form a 5-sided box pan;
• and
• v) an outer fire retardant coating, positioned across the first metal piece, and to the adjacent portions of the interior framing member of the curtain wall construction and the floor located thereadjacent.
