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 first soda lime glass sheet; and

the second pane comprising no more than two glass sheets,

the first glass sheet of the second pane having a thickness of 0.5 to 1.1 mm and comprising;

a first face and a second face; and

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

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

the second pane further comprising;

a solid inorganic electrochromic material having a first face and a second face, wherein the first face of the solid inorganic electrochromic material is disposed on the first face of the first glass sheet of the second pane; and

a protective layer disposed on the second face of the solid inorganic electrochromic material, the protective layer minimizing deleterious effects of exposing the solid inorganic electrochromic material to the environment, wherein the protective layer is not a glass sheet; and

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

2. The architectural window according to claim 1, wherein the solid inorganic electrochromic material comprises an electrode layer, a counter electrode layer, and an ion conducting layer.

3. The architectural window according to claim 1, wherein the first glass sheet of the second pane has a sodium oxide content of 10 percent by weight or less.

4. The architectural window according to claim 1, wherein the first glass sheet of the second pane has an alkali oxide content of 5 percent by weight or less.

5. The architectural window according to claim 1, wherein the first glass sheet of the second pane has an alkali oxide content is from 0.1 to 10 percent by weight.

6. The architectural window according to claim 1, wherein the laminate layer comprises a material selected from the group consisting of polyvinyl butyral, thermoplastic, a thermoplastic ionoplast, polycarbonate, polyurethane, a UV curable polymer, silicone, and combinations thereof.

7. The architectural window of claim 1, wherein the first glass sheet of the second pane has an alkali oxide content of 0.5 percent by weight or less.

8. The architectural window of claim 1, wherein the first glass sheet of the second pane has a sodium oxide content of 5 percent by weight or less.

9. The architectural window of claim 8, wherein the first glass sheet of the second pane has a sodium oxide content of 0.5 percent by weight or less.

10. The architectural window of claim 1, wherein the protective material comprises a mechanically durable layer having a thickness of 0.5 mm or less.

11. The architectural window of claim 10, wherein the protective material comprises a mechanically durable layer having a thickness of 0.1 mm or less.

12. The architectural window of claim 1, wherein the protective material has a coefficient of thermal expansion (CTE) of 50×
