A glass roof shingle includes a shingle cover layer made of a glass. A shingle base layer is disposed underneath the shingle cover layer. The shingle base layer and shingle cover layer define a cavity. A seal area formed between the shingle base layer and shingle cover layer and around the cavity controls ingress of moisture into the cavity. A photovoltaic module may be disposed within the cavity.

A glass element having a thickness from 25 ?m to 125 ?m, a first primary surface, a second primary surface, and a compressive stress region extending from the first primary surface to a first depth, the region defined by a compressive stress ?I of at least about 100 MPa at the first primary surface. Further, the glass element has a stress profile such that it does not fail when it is subject to 200,000 cycles of bending to a target bend radius of from 1 mm to 20 mm, by the parallel plate method. Still further, the glass element has a puncture resistance of greater than about 1.5 kgf when the first primary surface of the glass element is loaded with a tungsten carbide ball having a diameter of 1.5 mm.

Disclosed herein are methods for making asymmetric laminate structures and methods for reducing bow in asymmetric laminate structures, the methods comprising differentially heating the laminate structures during lamination or differentially cooling the laminate structures after lamination. Also disclosed herein are methods for reducing bow in asymmetric laminate structures, the methods comprising subjecting at least one substrate in the laminate structure to asymmetric tempering or annealing prior to lamination. Further disclosed herein are laminate structures made according to such methods.

A strengthened cover glass or glass-ceramic sheet or article as well as processes and systems for making the strengthened glass or glass-ceramic sheet or article is provided for use in consumer electronic devices. The process comprises cooling the cover glass sheet by non-contact thermal conduction for sufficiently long to fix a surface compression and central tension of the sheet. The process results in thermally strengthened cover glass sheets for use in or on consumer electronic products.

A strengthened architectural glass or glass-ceramic sheet or article as well as processes and systems for making the strengthened architectural glass or glass-ceramic sheet or article is provided. The process comprises cooling the architectural glass sheet by non-contact thermal conduction for sufficiently long to fix a surface compression and central tension of the sheet. The process results in thermally strengthened architectural glass sheets that may be incorporated into one or more panes in single or multi-pane windows.
