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.

Claims (37)

1. An interlocking curtain wall insulation system, comprising:

at least first and second vertically disposed and parallel mullions;

at least one upper horizontally disposed transom and at least one lower horizontally disposed transom;

said at least one upper and lower transoms being substantially parallel and being substantially perpendicular to said mullions;

first and second opposed backer bar brackets positioned on said at least first and second vertically disposed and parallel mullions, respectively;

a backer bar extending between and supported by said first and second opposed backer bar brackets;

at least one upper insulation hanger depending from said at least one upper transom and at least one lower insulation hanger depending from said at least one lower transom; and,

a safing insulation extending between a floor slab and said backer bar.

2. The interlocking curtain wall insulation system of claim 1 further comprising a safing clip engaging said floor slab and said safing insulation.

3. The interlocking curtain wall insulation system of claim 1 , said safing insulation engaging said lower insulation hanger.

4. The interlocking curtain wall insulation system of claim 1 further comprising an upper curtain wall insulation depending from said at least one upper insulation hanger and engaging said safing insulation disposed against said backer bar.

5. The interlocking curtain wall insulation system of claim 4 , said upper curtain wall insulation being in compression between said upper transom and said safing insulation.

6. The interlocking curtain wall insulation system of claim 1 further comprising a lower curtain wall insulation depending from said at least one lower insulation hanger to said at least one lower transom.

7. The interlocking curtain wall insulation system of claim 1 , said at least one upper insulation hanger comprising at least one leg for engaging said at least one upper transom.

8. The interlocking curtain wall insulation system of claim 1 , said at least one lower insulation hanger comprising at least one leg for engaging said backer bar.

9. The interlocking curtain wall insulation system of claim 1 , said backer bar being substantially T-shaped.

10. An interlocking curtain wall insulation system, comprising:

a frame for a curtain wall insulation comprising:

at least one frame defined by parallel and intersecting transoms and mullions;

first and second opposed backer bar brackets mounted to said mullions;

a backer bar extending between said backer bar brackets;

at least a first insulation hanger depending from one of said transoms;

at least a second insulation hanger fastened to said backer bar; and,

a safing insulation disposed between a floor slab and said backer bar.

11. The interlocking curtain wall insulation system of claim 10 said safing insulation engaging said at least second insulation hanger and said floor slab.

12. The interlocking curtain wall insulation system of claim 10 further comprising a first curtain wall insulation depending from said at least first insulation hanger and compressively engaging said safing insulation.

13. The interlocking curtain wall insulation system of claim 10 , further comprising a second curtain wall insulation depending from said at least one second insulation hanger.

14. An interlocking curtain wall system, comprising:

a frame connected to a building structure comprising:

at least first and second parallel transoms;

at least first and second parallel mullions;

said at least first and second parallel transoms operably engaging said at least first and second parallel mullions;

a backer bar supported by backer bar brackets, said backer bar brackets positioned on said at least first and second parallel mullions;

an insulation comprising:

a safing insulation extending between a floor slab and said backer bar and compressively fit therein;

an upper curtain wall insulation depending from an upper insulation hanger and compressing said safing insulation; and,

a lower curtain wall insulation positioned beneath said upper curtain wall insulation opposite said backer bar.
