1. A window comprising:
- a vacuum insulated glass (VIG) window unit in a window frame;
said VIG window unit comprising first and second glass substrates with a low pressure gap provided therebetween, the low pressure gap being at pressure less than atmospheric pressure;
said window frame comprising a plurality of elongated cavities that do not contact the first or second glass substrates of the VIG window unit and that are not located between the first and second glass substrates of the VIG window unit;
a vacuum insulated structure located in at least one of said elongated cavities of said window frame, said vacuum insulated structure comprising a sealed flexible envelope that encases insulating material, and wherein an interior of said sealed flexible envelope is at a pressure less than atmospheric pressure; and
wherein the sealed flexible envelope does not contact the first or second glass substrates of the VIG window unit, and no part of the sealed flexible envelope is located between the first and second glass substrates of the VIG window unit.

Abstract
A window includes a vacuum insulating glass (VIG) window unit in a window frame. The window frame includes at least one vacuum insulated structure (VIS) for improving the insulating functionality of the frame, so that the frame can adequately insulate the periphery of the VIG unit. Such windows may be used in residential and/or commercial window applications for buildings. The use of a window frame having at least one VIS is advantageous in that allows for improved window frame thermal performance and a narrow frame design if desired for improved aesthetics.
