A window includes an insulated glass unit and a frame supporting the insulated glass unit. The insulated glass unit includes a first glass pane and a second glass pane spaced from the first glass pane. A central plane extends through a pocket defined between the first glass pane and the second glass pane. The frame includes a first material visible on a first side of the window. The window also includes cladding connected to the frame. The cladding includes a second material visible on a second side of the window. The frame defines a cavity that extends between the first side and the second side and inhibits moisture from the first side contacting the second material. The window includes a thermal cavity defined by the frame and aligned with the pocket.

1. A window comprising: an insulated glass unit including: a first glass pane; anda second glass pane spaced from the first glass pane, the first glass pane and the second glass pane defining a pocket therebetween, wherein a central plane extends through the pocket and is spaced equal distances from the first glass pane and the second glass pane;a frame supporting the insulated glass unit, the frame including a first material, wherein the first material is visible on a first side of the window;cladding connected to the frame, the cladding including a second material, wherein the second material is visible on a second side of the window, wherein the frame defines a cavity that extends between the first side and the second side and is configured to inhibit moisture from the first side contacting the second material;a thermal cavity defined by a middle portion of the frame intermediate the first side and the second side and circumscribing the insulated glass unit, the middle portion of the frame supporting the insulated glass unit, wherein the thermal cavity is aligned with the pocket such that the central plane extends through a middle portion of the thermal cavity, the thermal cavity and the pocket defining a continuous thermal break extending through the window; andan insulating material within the thermal cavity. 2. The window of claim 1, wherein a distance between a central plane of the thermal cavity and the central plane of the pocket is in a range of up to about 0.5 inches. 3. The window of claim 2, wherein the thermal cavity has a width in a range of about 1 inches to about 2 inches. 4. The window of claim 1, wherein the first material includes aluminum and the second material includes at least one of metal, wood, vinyl, and fiberglass. 5. The window of claim 1, wherein the frame includes a header, a sill, jambs, and corner keys, wherein each corner key extends into a first opening in one of the header and the sill and into a second opening in one of the jambs to form a corner of the frame. 6. The window of claim 1, wherein one of the frame and the cladding includes a keyway and the other of the frame and the cladding includes a key extending into the keyway, wherein the keyway is sized to allow the frame and the cladding to move relative to each other. 7. The window of claim 1, wherein the insulated glass unit is connected to the frame such that the position of the insulated glass unit is fixed relative to the frame. 8. The window of claim 1 further including a sash frame circumscribing the insulated glass unit and positioned in the frame. 9. The window of claim 8, wherein the sash frame and the insulated glass unit are at least one of pivotable and slidable when positioned in the frame. 10. The window of claim 8, wherein the sash frame defines a second thermal cavity intermediate the first side and the second side, wherein the second thermal cavity is aligned with the pocket such that the central plane extends through the second thermal cavity. 11. The window of claim 1, in combination with a wall in which the window is mounted. 12. The window of claim 1, wherein the thermal cavity has a width greater than a width of the pocket and the first glass pane and the second glass pane are located within the extents of the thermal cavity. 13. The window of claim 1, wherein the central plane extends through a center of the thermal cavity and forms a common central plane of the window with substantially equal portions of the frame extending on each side of the common central plane. 14. A window comprising: an insulated glass unit including: a first glass pane; anda second glass pane spaced from the first glass pane, the first glass pane and the second glass pane defining a pocket therebetween, wherein a central plane extends through the pocket and is spaced equal distances from the first glass pane and the second glass pane;a frame supporting the insulated glass unit, the frame including a first material, wherein the first material is visible on a first side of the window;cladding connected to the frame, the cladding including a second material, wherein the second material is visible on a second side of the window, wherein the frame defines a cavity that extends between the first side and the second side and is configured to inhibit moisture from the first side contacting the second material;a first thermal cavity defined by the frame intermediate the first side and the second side and circumscribing the insulated glass unit, wherein the first thermal cavity is aligned with the pocket such that the central plane extends through the first thermal cavity; andan insulating material within the first thermal cavity;a sash frame circumscribing the insulated glass unit and positioned in the frame; anda second thermal cavity defined by the sash frame intermediate the first side and the second side, wherein the second thermal cavity is aligned with the pocket such that the central plane extends through the second thermal cavity, and wherein the first thermal cavity, the second thermal cavity, and the pocket define a continuous thermal break extending through the window. 15. The window of claim 14, wherein the central plane extends through a middle portion of the first thermal cavity. 16. The window of claim 14, wherein the central plane extends through a middle portion of the second thermal cavity.
