Abstract

A novel impact and blast resistant window is presented. A surface of a window pane that is adjacent to an interior of a building has a durable transparent polymer film coated or adhered thereto. The surface of a window pane that is adjacent to an interior of a building 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 durable polymer film coated or adhered to a surface of the window pane, with the durable polymer film positioned on a surface of window pane that is directly adjacent to an interior of a building in which the window sash is mounted; and

wherein the durable polymer film is secured 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.

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

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

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, and said second window pane is adjacent to an exterior of the building in which said window sash in mounted.

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 one surface of the double sided tape adheres to a sealing surface of a mounting space in the opening of the window sash;

and

the film-covered surface of the window faces and adheres to an opposite surface 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 a durable polymer film is coated or adhered to two surfaces of said window pane surfaces.

16. An impact and blast resistant window, comprising:

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

a durable polymer film adhered or coated on a surface of the window pane, with the durable polymer film positioned adjacent to an interior of a building in which the window sash is mounted;

wherein the durable polymer film is adhered to the window sash by an adhesive;

wherein the window will meet 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 and to 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 and to at least a portion of a perimeter of said durable polymer film by the adhesive, and wherein the adhesive 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 and to at least a portion of a perimeter of said durable polymer film by the adhesive, and wherein the adhesive is positioned between said polymer film and said window sash, and said adhesive does not extend beyond a perimeter of said opening in said sash that is covered by said window pane.
