Abstract: The present invention provides methods and apparatuses for securing safing insulation in the gap formed between a spandrel and a slab. Additionally, the present invention eliminates the need for stiffening tees and/or stiffening brackets. In one exemplary embodiment, the present invention utilizes a first portion of safing secured to spandrel insulation positioned in an exterior wall structure and a second portion of safing insulation positioned adjacent to the first portion of safing insulation and between the spandrel insulation and the slab. By fixedly securing the first portion of safing insulation to the spandrel insulation, any deformation of the spandrel insulation caused by the forces exerted by the compressed second portion of safing insulation on spandrel insulation results in the first portion of safing insulation moving with the spandrel insulation.

Abstract: An interlocking curtain wall insulation system for a building having a backer bar spaced from a floor slab defining a perimeter void between the floor slab and an outer wall, a safing insulation disposed above the backer bar and compression fit within the perimeter void between the floor slab and the backer bar, a first curtain wall insulation extending from an upper surface of the safing insulation adjacent the backer bar, a second curtain wall insulation depending from the backer bar.

Abstract: The interlocking curtain wall insulation system comprises a frame connected to a building structure having at least first and second parallel transoms, at least first and second parallel mullions, the at least first and second parallel transoms operably engaging the at least first and second parallel mullions. The device further comprises an insulation including a safing insulation extending between a floor slab and the backer bar and compressively fit therein, an upper curtain wall insulation depending from an upper insulation hanger and compressing the safing insulation, and a lower curtain wall insulation depending from a lower insulation hanger.
