A window assembly according to various embodiments includes a frame, a sash, an insulating unit (e.g., one or more glass panels), a glass stop, an elongated frame insulating element slidably disposed on an inner surface of the frame, an elongated sash insulating element slidably disposed on an outer surface of the sash, and an elongated inner sash insulating element slidably disposed on an inner surface of the sash. The elongated frame insulating element, the elongated sash insulating element, and the elongated inner sash insulating element each define a plurality of chambers that extend substantially parallel to a longitudinal axis of each element. These chambers reduce the size of the space between the frame and sash and the size of the space between the sash, the insulating unit, and the glass stop, which results in smaller convection currents within these spaces and a more thermally efficient window assembly.

1. A window assembly comprising: a. a glass panel, a sash extending around the glass panel, and a frame extending around the sash;b. wherein the frame comprises an inner frame portion configured to face an interior of a building, an outer frame portion configured to face an exterior of the building, and a frame insulating portion separating and spacing the inner frame portion from the outer frame portion, wherein the inner and outer frame portions comprise a relatively high thermal conductivity and the frame insulating portion comprises a relatively low thermal conductivity;c. wherein the sash comprises an inner sash portion configured to face the interior of the building, an outer sash portion configured to face the exterior of the building, and a sash insulating portion separating and spacing the inner sash portion from the outer sash portion, wherein the inner and outer sash portions comprise a relatively high thermal conductivity and the sash insulating portion comprises a relatively low thermal conductivity;d. a glass stop extending along an inner surface of the sash, the glass stop configured to retain the glass panel in the window assembly, wherein the glass stop is separated from the glass panel by a glass insulating member, wherein the glass stop, the glass insulating member, and the sash at least partially define a cavity, wherein a sash insulating element comprising a plurality of longitudinally extending chambers extends through the cavity, around an entire perimeter of the sash, and extends between and abuts the sash insulating portion and the glass stop;e. wherein an inner surface of the frame faces an outer surface of the sash;f. wherein a frame insulating element having a relatively low thermal conductivity extends along an entire perimeter of the inner surface of the frame and a second sash insulating element having a relatively low thermal conductivity extends along an entire perimeter of the outer surface of the sash;g. wherein the glass panel, glass insulating member, frame insulating portion, sash insulating portion, frame insulating element, sash insulating element and second sash insulating element are part of a conductive and convective thermal barrier continuously separating the inner frame and sash portions from the outer frame and sash portions. 2. The window assembly of claim 1, wherein the frame insulating portion comprises two frame thermal breaks and a frame foam member, wherein the two frame thermal breaks extend between the exterior and interior portions of the frame and define a frame cavity, wherein the frame foam member extends through the frame cavity and abuts the two frame thermal breaks. 3. The window assembly of claim 2, wherein the sash insulating portion comprises two sash thermal breaks and a sash foam member, wherein the two sash thermal breaks extend between the exterior and interior portions of the sash and define a sash cavity, wherein the sash foam member extends through the sash cavity and abuts the two sash thermal breaks. 4. The window assembly of claim 1, wherein the frame and second sash insulating elements each comprises a plurality of longitudinally extending chambers. 5. The window assembly of claim 4, wherein at least one of an inner surface of the frame insulating element and an outer surface of the second sash insulating element comprises a finger extending therefrom. 6. The window assembly of claim 5, wherein the inner surface of the frame insulating element and the outer surface of the second sash insulating element each comprise a plurality of ribs extending therefrom. 7. The window assembly of claim 1, wherein the inner and outer frame and sash portions each define a plurality of extruded walls. 8. The window assembly of claim 7, wherein the extruded walls of the inner frame and sash portions are thicker than the extruded walls of the outer frame and sash portions. 9. A window assembly, comprising: a. a glass panel and a frame extending around the glass panel;b. wherein the frame comprises an inner frame portion configured to face an interior of a building, an outer frame portion configured to face an exterior of the building, and a frame insulating portion separating and spacing the inner frame portion from the outer frame portion, wherein the inner and outer frame portions comprise a relatively high thermal conductivity and the frame insulating portion comprises a relatively low thermal conductivity;c. a glass stop extending along an inner surface of the frame, the glass stop configured to retain the glass panel in the window assembly;d. wherein a glass insulating member separates the glass stop from the glass panel, wherein the glass stop has a relatively high thermal conductivity and the glass insulating member has a relatively low thermal conductivity;e. wherein the glass panel, the frame insulating portion, and the glass insulating member are part of a conductive and convective thermal barrier continuously separating the inner frame portion from the outer frame portion; andf. wherein the glass stop, glass insulating member, and the inner surface of the frame at least partially define a cavity, and wherein a frame insulating member having a plurality of longitudinally extending chambers extends through the cavity around an entire perimeter of the frame and extends between and abuts the frame insulating portion and the glass stop, wherein the frame insulating member is part of the conductive and convective thermal barrier continuously separating the inner frame portion from the outer frame portion. 10. The window assembly of claim 9, wherein the frame insulating portion comprises two frame thermal breaks and a frame foam member, wherein the two frame thermal breaks extend between the exterior and interior portions of the frame and define a frame cavity, wherein the frame foam member extends through the frame cavity and abuts the two frame thermal breaks. 11. The window assembly of claim 9, wherein the inner and outer frame portions each define a plurality of extruded walls. 12. The window assembly of claim 11, wherein the extruded walls of the inner frame portion are thicker than the extruded walls of the outer frame portion. 13. The window assembly of claim 9, wherein an inner surface of the frame insulating member comprises a finger extending therefrom. 14. The window assembly of claim 13, wherein the inner surface of the frame insulating member comprises a plurality of ribs extending therefrom.
