Abstract

A novel impact and blast resistant window is presented. A surface of a glazing pane has a durable transparent polymer film coated or adhered thereto. The surface of the window pane having the film is sealed to the sash by double sided tape. The resulting window produces an unexpected ability for the durable transparent polymer film to retain pieces of broken glass driven toward the interior of the building by a missile striking an exterior of the window, without the durable transparent polymer film pulling loose from the window sash.

Claims

1. An impact and blast resistant window, comprising:

a window sash having an opening therein for receiving a window pane;

a window pane positioned in the opening of the window sash;

a durable polymer film coated or adhered to a surface of the window pane;

wherein the window pane and the durable polymer film are secured to the window sash by adhering one side of a double sided tape to said window sash and adhering an opposite side of said double sided tape to said durable polymer film; and

wherein the double sided tape comprises closed-cell foam positioned between the one side of the double sided tape and the opposite side of the double sided tape.

2. An impact and blast resistant window as described in claim 1, wherein the opposite side of said double sided tape is adhered to a perimeter of said durable polymer film.

3. An impact and blast resistant window as described in claim 1, wherein the opposite side of said double sided tape is adhered to an entire perimeter portion of said durable polymer film.

4. An impact and blast resistant window as described in claim 1, wherein the double sided tape is positioned between said durable polymer film and said window sash.

5. An impact and blast resistant window as described in claim 1, wherein the double sided tape is positioned between said polymer film and said window sash, and said double sided tape does not extend beyond a perimeter of said opening in said sash that is covered by said window pane.

6. An impact and blast resistant window as described in claim 1, further comprising a second window pane positioned in the opening of the window sash, wherein the second window pane is spaced apart from said window pane.

7. An impact and blast resistant window as described in claim 1, wherein the window pane comprises glass.

8. An impact and blast resistant window as described in claim 1, wherein the window sash comprises a material that is selected from one or more of the group consisting of wood, metal, vinyl and plastic.

9. An impact and blast resistant window as described in claim 1, wherein the polymer film has a thickness between 7 mils and 25 mils.

10. An impact and blast resistant window as described in claim 1, wherein the one side of the double sided tape adheres to a sealing surface of a mounting space in the opening of the window sash;

and

the polymer film-covered surface of the window faces and adheres to the opposite side of the double sided tape.

11. An impact and blast resistant window as described in claim 6, wherein the window pane and the second window pane are spaced apart by a distance of from about 6 mm to about 20 mm.

12. An impact and blast resistant window as described in claim 1, wherein the durable polymer film comprises a laminated film.

13. An impact and blast resistant window as described in claim 1, wherein the window is a double glazed window.

14. An impact and blast resistant window as described in claim 1, wherein the window is a triple glazed window.

15. An impact and blast resistant window as described in claim 1, wherein said window comprises a plurality of window pane surfaces, and two surfaces of said plurality of window pane surfaces comprise a durable polymer film coated or adhered thereon.

20. An impact and blast resistant window as described in claim 1, wherein the double sided tape comprises an acrylic closed cell foam layer.

22. An impact and blast resistant window as described in claim 1, wherein the double sided tape is 3M VHB 4991 or equivalent.

24. An impact and blast resistant window as described in claim 1, further comprising a second window pane positioned in the opening of the window sash, wherein the second window pane is spaced apart from said window pane, and a surface of the second window pane comprises a durable polymer film coated or adhered thereon.

27. An impact and blast resistant window as described in claim 1, wherein the durable polymer film comprises metal oxide.

16. An impact and blast resistant window, comprising:

a window sash having an opening therein for receiving a window pane;

a window pane positioned in the opening of the window sash;

a durable polymer film adhered or coated on a surface of the window pane;

wherein the window pane and the durable polymer film are adhered to the window sash by adhering one side of a double sided tape to said window sash and an opposite side of said double sided tape to said durable polymer film;

wherein the double sided tape comprises closed-cell foam positioned between the one side of the double sided tape and the opposite side of the double sided tape; and

wherein the impact and blast resistant window meets ASTM E1886-02 and ASTM E1996-03 standards.

17. An impact and blast resistant window as described in claim 16, wherein the durable polymer film is adhered to the window sash by the opposite side of said double sided tape at an entire perimeter portion of said durable polymer film.

18. An impact and blast resistant window as described in claim 16, wherein the durable polymer film is adhered to the window sash at a perimeter of said durable polymer film by the opposite side of said double sided tape, and wherein the double sided tape is positioned between said durable polymer film and said window sash.

19. An impact and blast resistant window as described in claim 16, wherein the durable polymer film is adhered to the window sash at a perimeter of said durable polymer film by the opposite side of said double sided tape, and wherein the double sided tape is positioned between said polymer film and said window sash, and said double sided tape does not extend beyond a perimeter of said opening in said sash that is covered by said window pane.

21. An impact and blast resistant window as described in claim 16, wherein the double sided tape comprises an acrylic closed cell foam layer.

23. An impact and blast resistant window as described in claim 16, wherein the double sided tape is 3M VHB 4991 or equivalent.

25. An impact and blast resistant window as described in claim 16, further comprising a second window pane positioned in the opening of the window sash, wherein the second window pane is spaced apart from said window pane.

26. An impact and blast resistant window as described in claim 16, further comprising a second window pane positioned in the opening of the window sash, wherein the second window pane is spaced apart from said window pane, and a surface of the second window pane comprises a durable polymer film coated or adhered thereon.

28. An impact and blast resistant window as described in claim 16, wherein the durable polymer film comprises metal oxide.
