Encapsulated insulated glass unit

An insulated glass unit comprising:

• a first glass pane having a first edge;
• a second glass pane having a second edge, wherein the first glass pane and the second glass pane are in a parallel spaced arrangement;
• a rigid plastic spacer between the first glass pane and the second glass pane;
• and
• a plastic frame that is formed by injection molding to encapsulate the first edge and the second edge so that the plastic frame forms an air-tight seal with the first glass pane and the second glass pane,
• wherein the spacer is covered by the plastic frame and has a T-shape with an inner body portion and an exterior flange portion, so that the inner body portion is between the first glass pane and the second glass pane, and the exterior flange portion contacts the first edge and the second edge of the first glass pane and the second glass pane,
• wherein the plastic frame covers the second spacer at a first surface of the plastic frame, wherein the plastic frame has an outer surface that is opposite the first surface, wherein the plastic frame has a lip projecting from the outer surface, and wherein the lip is comolded with the plastic frame.

An insulated glass unit comprising:

• a first glass pane having a first edge;
• a second glass pane having a second edge,
• a third glass pane between the first glass pane and the second glass pane, and having a third edge, wherein the first glass pane, the second glass pane, and the third glass pane are in a parallel spaced arrangement;
• a first spacer between the first glass pane and the third glass pane so that the first spacer, the first glass pane, and the third glass pane define a first interior space;
• a second spacer between the second glass pane and the third glass pane so that the second spacer, the second glass pane, and the third glass pane define a second interior space;
• a rigid plastic third spacer;
• and
• a plastic frame that is formed by injection molding to encapsulate the first edge and the second edge so that the plastic frame forms an air-tight seal with the first glass pane and the second glass pane,
• wherein the third spacer is covered by the plastic frame and has a T-shape with an inner body portion and an exterior flange portion, so that the inner body portion is between the first glass pane and the second glass pane and contacts the third edge, and the exterior flange portion contacts the first edge and the second edge of the first glass pane and the second glass pane respectively,
• wherein the plastic frame covers the second spacer at a first surface of the plastic frame, and the plastic frame has an outer surface that is opposite the first surface, and the plastic frame has a lip projecting from the outer surface, wherein the lip is comolded with the plastic frame.
