Abstract:
An insulating window shade has a compressible fill container having a first end and a second end, wherein the first end of the compressible fill container is configured to be moveable between an expanded position and a compressed position. A fill material is disposed substantially uniformly within the compressible fill container, wherein the fill material is capable of being repeatedly compressed and expanded as the compressible fill container is moved between the expanded position and the compressed position. The fill material forms a thermal boundary for trapping gas, reducing convection and contribute to aesthetic properties of the window shade. A divider control and coordination system enables movement of the divider, thereby changing the aesthetic and/or insulating properties of the insulating window panel. In the compressed position, the length of the compressible fill container is approximately 25% or less than the length of the compressible fill container in the expanded position.
