Abstract

A window sill includes a metal form having inner and outer surfaces and a shape defining an inner space. The window sill also includes a fill piece positioned in the inner space so that an upper surface of the fill piece is adjacent to and forms a seal with the inner surface of the metal form. The window sill further includes a window assembly for holding a pane of glass. The window sill is positioned on and forms a seal with the outer surface of the metal form.

Claims

1. A window sill, comprising:

a metal form having inner and outer surfaces and a shape defining an inner space; and

a fill piece positioned in the inner space, an upper surface of the fill piece being adjacent to the inner surface of the metal form.

2. The sill of claim 1, further including a window assembly for holding a pane of glass, the window assembly being positioned on the outer surface of the metal form.

3. The sill of claim 1, wherein the metal form has opposed downwardly extending sidewalls for overlapping opposite sides of a masonry wall.

4. The sill of claim 1, wherein the metal form is of a flexible sheet metal held rigid by the fill piece.

5. The sill of claim 1, wherein the fill piece has a shape complementary to the shape of the metal form.

6. The sill of claim 1, wherein the inner space of the metal form is defined by a first wall, integrally formed first and second sidewalls extending downwardly therefrom the first wall, a second wall extending from the first sidewall, and a third sidewall extending downwardly therefrom the second wall.

7. The sill of claim 6, wherein the first and second walls are oriented at a non-zero angle relative to each other.

8. The sill of claim 1, wherein the fill piece includes one of foam material and rigid material.

9. The sill of claim 8, wherein the rigid material includes one of concrete fill, mortar, and grout.

10. A window sill incorporated in a masonry construction, comprising:

a masonry wall with an upper surface;

a window sill carried by and sealed to the upper surface of the masonry wall, the window sill including

a metal form having inner and outer surfaces and a shape defining an inner space, the inner space of the metal form being defined by a first wall, integrally formed first and second sidewalls extending downwardly therefrom the first wall, a second wall extending from the second sidewall, and a third sidewall extending downwardly therefrom the second wall; and

a fill piece positioned in the inner space and sealed to the inner surface of the metal form.

11. The sill of claim 10, further including a window assembly positioned on and sealed to the outer surface of the metal form, the window assembly defining a trench for receiving a pane of glass.

12. The sill of claim 10, wherein the metal form is flexible and conforms to the shape of the fill piece.

13. The sill of claim 10, furthering including masonry binding material in the masonry wall, the masonry binding material being adjacent to and forming a seal with a lower surface of the fill piece.

14. The sill of claim 10, wherein the first and third downwardly extending sidewalls are adjacent to and sealed with opposite sides of the masonry wall.

15. The sill of claim 10, wherein an upper surface of the fill piece has a first surface portion, a second surface portion extending downwardly from the first surface portion, and a third surface portion extending from the second surface portion.

16. The sill of claim 10, wherein the shape of an upper surface of the fill piece is chosen to conform to the inner surface of the metal form.

17. A method of installing a window sill, comprising:

providing a masonry wall with an upper surface;

providing a window sill on the upper surface of the masonry wall, the window sill being sealed to the upper surface of the masonry wall, the window sill including

a fill piece positioned on the upper surface of the masonry wall,

a metal form having inner and outer surfaces and a shape defining an inner space, the fill piece being received by the inner space, an upper surface of the fill piece being adjacent to and sealed with the inner surface of the metal form; and

providing a window assembly for holding a pane of glass, the window assembly being positioned on and sealed with the outer surface of the metal form.

18. The method of claim 17, wherein the inner space of the metal form is defined by a first wall, integrally formed first and second sidewalls extending downwardly therefrom the first wall, a second wall extending from the second sidewall, and a third sidewall extending downwardly therefrom the second wall.

19. The method of claim 18, wherein the step of providing the window sill includes positioning the first and third sidewalls on opposite sides of the masonry wall.

20. The method of claim 17, wherein the step of providing the window sill includes positioning the fill piece in the inner space of the metal form before the window sill is positioned on the upper surface of the masonry wall.

21. The method of claim 17, further including bending the shape of the metal form to conform to a shape of the fill piece.

22. The method of claim 18, wherein the first and second walls are oriented at a non-zero angle relative to each other.
