Publication Summary
An improved insulated glazing unit is provided which can attain about R5 to about R10 thermal performance at the center of the glass while having dimensions about the same as those of a conventional double glazed insulated glazing unit. An outer glazing and inner glazing are sealed to a spacer to form a gas impermeable space. One or more rigid, non-structural glazings are attached to the inside of the spacer to divide the space between the inner and outer glazings to provide insulating gaps between glazings of from about 0.20 inches to about 0.40 inches. One or more glazing surfaces facing each thermal gap are coated with a low emissivity coating. Finally, the thermal gaps are filled with a low conductance gas such as krypton gas.| Country | United States |

Thermal insulated glazing unit
Abstract
An improved insulated glazing unit is provided which can attain about R5 to about R10 thermal performance at the center of the glass while having dimensions about the same as those of a conventional double glazed insulated glazing unit. An outer glazing and inner glazing are sealed to a spacer to form a gas impermeable space. One or more rigid, non-structural glazings are attached to the inside of the spacer to divide the space between the inner and outer glazings to provide insulating gaps between glazings of from about 0.20 inches to about 0.40 inches. One or more glazing surfaces facing each thermal gap are coated with a low emissivity coating. Finally, the thermal gaps are filled with a low conductance gas such as krypton gas.

Claims
What is claimed is:
1. An insulated glazing unit for constructing thermal windows comprising:
an outer glazing having an exterior surface and a center-facing surface,
an inner glazing having an interior surface and a center-facing surface, said
inner glazing being held parallel to and spaced away from said outer glazing
such that the center-facing surface of said outer glazing and the center-facing
surface of said inner glazing face each other,
a means for sealing said inner glazing and said outer glazing together to form
a gas impermeable space between said i...
