Draft guard for window assembly having seals and integral fins

1. A draft guard for a window assembly, said draft guard comprising:

a piece of weatherstopping material;

a bend in said piece of weatherstopping material with said bend defining a horizontal component and a vertical component angularly offset from said horizontal component;

a formed foam seal being a continuous member extending around a portion of said horizontal component and extending outwardly from said horizontal component, said foam seal having an opening with said horizontal component extending through said opening of said foam seal such that said foam seals extends around the portion of said horizontal component to offset said foam seal in a different plane from said vertical component; and

at least one fin extending outwardly from and integral with at least one side of said vertical component.

2. A draft guard as set forth in claim 1 wherein said at least one fin comprises a plurality of fins extending laterally across and spaced longitudinally along said vertical component.

3. A draft guard as set forth in claim 2 wherein said vertical component includes an aperture defined therein for receiving a pivot bar.

4. A draft guard as set forth in claim 3 wherein said one of said fins is spaced on one side of said aperture and at least another one of said fins is spaced on another side of said aperture.

5. A draft guard as set forth in claim 2 wherein said fins extend outwardly from the same side of said vertical component.

6. A draft guard as set forth in claim 2 wherein said vertical component includes a post extending outwardly from a side opposite the side having said fins.

7. A draft guard as set forth in claim 1 wherein said foam seal comprises a compressible foam material.

8. A draft guard as set forth in claim 7 wherein said compressible foam material is an open cell foam.

9. A draft guard as set forth in claim 7 wherein said compressible foam material is a closed cell foam.

10. A draft guard as set forth in claim 7 wherein said compressible foam material is an articulated foam.

11. A draft guard as set forth in claim 1 wherein said fins are made of a thermoplastic elastomer (TPE).

12. A draft guard as set forth in claim 1 wherein said vertical component is about 90 degrees offset from a portion of said horizontal component.

13. A draft guard as set forth in claim 1 wherein said each of said vertical component and said horizontal component has a rectangular shape.

14. A draft guard as set forth in claim 1 wherein said horizontal component has opposed flanges extending outwardly, said foam seal being disposed between said flanges.

15. A draft guard as set forth in claim 1 wherein said foam seal is configured as a foam block.

16. A draft guard as set forth in claim 15 wherein said horizontal component has opposed flanges extending outwardly, said flanges being larger than said opening of said foam seal.

17. A draft guard as set forth in claim 15 wherein said horizontal component has opposed flanges extending outwardly, said flanges being smaller than said foam block.

18. A draft guard as set forth in claim 15 wherein said horizontal component has opposed flanges extending outwardly, one of said flanges being larger than another of said flanges.

19. A window assembly comprising:

a window frame;

first and second sashes contained in said window frame;

a balancer for containing said first and second sashes in said window frame, said balancer having a frame side component, a sash side component, and a spring connecting said frame side component and said sash side component; and

a draft guard coupled to said sash side component of said balancer and having:

a piece of weatherstopping material;

a bend in said piece of weatherstopping material with said bend defining a horizontal component and a vertical component angularly offset from said horizontal component, wherein said vertical component has an aperture extending therethrough;

a foam seal being a continuous member extending around a portion of said horizontal component and extending outwardly from said horizontal component, said foam seal having an opening with said horizontal component extending through said opening of said foam seal such that said foam seals extends around the portion of said horizontal component to offset said foam seal in a different plane from said vertical component; and

at least one fin extending outwardly from at least one side of said vertical component; and

a pivot bar inserted into said aperture and coupled to said balancer.

20. A window assembly as set forth in claim 19 wherein said draft guard is coupled to said sash component with an adhesive.

21. A window assembly as set forth in claim 19 wherein said draft guard is mechanically coupled to said sash component.

22. A window assembly as set forth in claim 19 wherein said vertical component of said draft guard includes a post extending outwardly and mechanically coupled to said balancer of said sash component.
