Window frame system for vacuum insulated glass unit
View Patent ↗A window assembly may include a vacuum insulated glass unit and a frame assembly. The vacuum insulated glass unit may include first and second glass substrates defining a space therebetween that is at a pressure lower than atmospheric pressure. One of the first and second glass substrates may include a vacuum port extending outward therefrom. The vacuum port may define a passage in communication with the space. The frame assembly supports the glass unit and may include a base member and a glazing member. The base member and the glazing member cooperate to define a slot in which an edge portion of the glass unit is received. The glazing member may include a cavity receiving the vacuum port. The glazing member and the base member may define a plurality of pockets that hinder thermal conductivity through the frame assembly.

3. The window assembly of claim 1 , wherein the base member includes embedded reinforcement members.
4. The window assembly of claim 1 , wherein the base member includes a recess adjacent the slot that receives a portion of the glass unit when the glass unit is in a distorted condition.
5. The window assembly of claim 4 , wherein the recess includes an insulative barrier received therein to absorb energy associated with distortion of the glass unit.
6. The window assembly of claim 1 , wherein the glazing member structurally supports the glass unit.
7. The window assembly of claim 1 , wherein the cavity that receives the vacuum port is filled with an insulative material.
8. The window assembly of claim 1 , wherein at least one of the pockets is filled with air.
9. The window assembly of claim 1 , wherein at least one of the pockets is filled with foam.
10. The window assembly of claim 1 , wherein at least one of the base member and the glazing member comprises vinyl having embedded additives that reduce thermal conductivity thereof.
11. The window assembly of claim 1 , wherein the edge portion of the glass unit is inserted into the slot to a bite depth of greater than or equal to 1.25 inches.
12. The window assembly of claim 1 , wherein the glazing member bears at least a portion of a load of the glass unit.
13. The window assembly of claim 12 , wherein the glazing member and the base member cooperate to bear the load of the glass unit.
14. A window assembly comprising:
a vacuum insulated glass unit including first and second glass substrates defining a space therebetween that is at a pressure lower than atmospheric pressure, one of the first and second glass substrates including a vacuum port, the vacuum port defining a passage extending through one of the first and second glass substrates in communication with the space; and
a frame assembly supporting the glass unit and including a base member and a glazing member, the base member and the glazing member cooperating to define a slot in which an edge portion of the glass unit is received, one of the base member or the glazing member including a recess adjacent the slot that receives a portion of the glass unit when the glass unit is in a distorted condition, wherein one of the base member or the glazing member includes a cavity receiving the vacuum port.
