Abstract
An electrochromic integrated glazing unit (IGU) comprises an electrochromic lite, a glass lite, a spacer, and a sealant. The electrochromic lite can have a first piece of carrier glass, a second piece of carrier glass, and an electrochromic device disposed between them, where the first and second pieces of carrier glass can be offset such that the first piece of carrier glass extends farther than both the second piece of carrier glass and the electrochromic device along a first edge of the electrochromic lite. A sealant can be disposed between the first piece of carrier glass and the glass lite along a first edge of the electrochromic IGU and further disposed between the second piece of carrier glass and the glass lite. An electrochromic laminated glass unit (LGU) with a similar electrochromic lite can contain one or more shear blocks disposed at a first edge of the electrochromic LGU.
