1. A laminated glass structure, comprising:
- a non-glass substrate comprising one or more layers of polymer-impregnated paper, an upper primary surface and a lower primary surface; and
a flexible glass sheet having a thickness of no greater than 0.3 mm laminated to the upper primary surface of the non-glass substrate with an adhesive,wherein the non-glass substrate comprises a lower moisture barrier at a selected depth from the lower primary surface.

Abstract
A laminated glass structure is provided that includes a non-glass substrate, a flexible glass sheet, and an adhesive. The non-glass substrate includes one or more layers of polymer-impregnated paper, an upper primary surface and a lower primary surface. The non-glass substrate also comprises a lower moisture barrier at a selected depth from the lower primary surface. The flexible glass sheet has a thickness of no greater than 0.3 mm and is laminated to the upper primary surface of the non-glass substrate with the adhesive. An optional upper moisture barrier can also be included within the non-glass substrate at a selected depth from the upper primary surface.

14. A laminated glass structure, comprising:
-
a non-glass substrate comprising a high pressure laminate (HPL), an upper primary surface and a lower primary surface; and a flexible glass sheet having a thickness of no greater than 0.3 mm laminated to the upper primary surface of the non-glass substrate with an adhesive, wherein the non-glass substrate comprises a lower moisture barrier at a selected depth from the lower primary surface, the moisture barrier having a thickness from about 20 microns to about 60 microns, wherein a total thickness of the non-glass substrate, the flexible glass sheet and the adhesive is from about 4 mm to about 25 mm, and further wherein the structure exhibits a change in bow of no more than ±
10 mm upon exposure to (a) a drying evolution at 70°
C. for 24 hours;
(b) a high humidity evolution at 23°
C. with a 90% relative humidity for 7 days; and
(c) a high humidity and temperature evolution at 40°
C. with a 95% relative humidity for 96 hours. - View Dependent Claims (9, 15, 16, 17, 18)
