Problems solved by technology

However, the thermal strengthening process may require thicker glass substrates, e.g., at least about 2-3 mm in thickness
As noted above, glass layers at this thickness can undesirably increase the overall thickness and / or weight of the IGU, and the additional tempering step can increase the manufacturing cost of the IGU
Additionally, thermal tempering can warp and / or cause birefringence in the center glass layer, degrading the optical quality of the IGU

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 x 10<-7> / DEG C over a temperature range of 0-300 DEG C.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority under 35 U.S.C. §119 to U.S. Provisional Application No. 62 / 609,069, filed December 21, 2017, the contents of which are incorporated herein by reference in their entirety. technical field [0003] The present disclosure generally relates to insulating glass units comprising at least one low CTE glass layer. More specifically, the present disclosure relates to windows comprising at least one glass layer having a CTE of less than 70x10, useful as multiple pane windows. -7 / °C multi-layer insulated glass unit. Background technique [0004] Insulating glass units (IGUs) are used as components in a variety of applications, including architectural, automotive, display and appliance components. IGUs can be used as multi-pane windows in buildings or automobiles to provide thermal insulation properties from the outside ambient temperature. An IGU typically consists of two or mo...
