Described is a construction for effectively thermally insulating and sealing of a safing slot between a floor of a building and an exterior wall construction wherein the exterior wall construction comprises a curtain wall configuration utilizing an interior panel module design. The Thermal insulating and sealing means includes a supplemental insulation means positioned above the primary insulation means and attached to the interior panel of a curtain wall construction to maintain thermally insulating and sealing of the safing slot during exposure to fire and heat which can cause the interior panel to deform from heat distorting to an extent beyond the capability of standard safing insulation for expanding in order to maintain a proper seal extending across the safing slot.
