Abstract

Laminated articles and layered articles, for example, low alkali glass laminated articles and layered articles useful for, for example, electrochromic devices are described.

Claims

1. An architectural window comprising:

at least a double pane window comprising a first pane and a second pane;

the first pane comprising a glass sheet; and

the second pane comprising no more than two glass layers,

the first glass layer comprising;

a first face and a second face;

a coefficient of thermal expansion from 20×

10<sup>−

7</sup>/C to 35×

10<sup>−

7</sup>/°

C.;

an alkali oxide content of 10 percent by weight or less;

and

a thickness of 2.5 mm or less;

the second glass layer comprising a substrate comprising a soda lime glass and having a thickness greater than that of the first glass layer; and

the second pane further comprising;

a solid inorganic electrochromic material disposed on the first face of the first glass layer; and

a laminate layer disposed on the second face of the first glass layer, between the substrate and the first glass layer.

2. The architectural window of claim 1, wherein the alkali oxide content is 5 percent by weight or less.

3. The architectural window of claim 2, wherein the alkali oxide content is 0.5 percent by weight or less.

4. The architectural window of claim 1, wherein the alkali oxide is sodium oxide.
