Abstract
An insulated glass unit is described and includes at least a first glass layer, a second glass layer and a third glass layer disposed therebetween. The third glass layer is separated from the first glass layer and the second glass layer by first and second sealed gap spaces. The third glass layer has a low CTE as compared to the CTE of the first and/or second glass layers. In some instances, the third glass layer has a CTE of less than 70×10−7/° C. over a temperature range of 0-300° C.
Claims20
An insulated glass unit comprising:
- a first glass layer having a first coefficient of thermal expansion (CTE1);
- a second glass layer and having a second coefficient of thermal expansion (CTE2);
- a third glass layer disposed between the first and second glass layers,
- a first sealed gap space defined between the first glass layer and the third glass layer;
- and
- a second sealed gap space defined between the second glass layer and the third glass layer, wherein the first sealed gap space and the second sealed gap space are hermetically sealed from one another;
- wherein the third glass layer has a third coefficient of thermal expansion (CTE3) over a temperature range 0-300° C. of less than 70×10−7/° C.;
- wherein the insulated glass unit has at least one of CTE1>2*CTE3 or CTE2>2*CTE3;
- wherein a thickness of at least one of the first glass layer or the second glass layer is greater than 2 mm;
- and
- wherein one or more of the first glass layer or the second glass layer is optically transparent.
