Various embodiments of the disclosure are directed towards fenestration assemblies having a first pane; a second pane, the second pane spaced from the first pane; and a third pane configured in spaced relation between the first pane and the second pane, where the third pane is a laminate. In one aspect, the total thickness of the third pane laminate is not greater than 3 mm. In one aspect, the laminate comprises a first glass layer not greater than 1 mm thick and a second glass layer not greater than 1 mm thick, and an interlayer between first and second layers.

The invention concerns a laminated glazing with an optically transparent area (22) comprising (i) at least one inner (13) and one outer (14) glass sheets, each having an internal and an external faces, and being high level of near infrared radiation transmission glass sheets, (ii) at least one thermoplastic interlayer (20) to laminate the at least the inner and the outer glass sheets, comprising at least a first zone (11) and a second zone (12), the second zone (12) being delimited by the optically transparent area (22), and (iii) at least ne optical sensor device (2) provided on the inner face of the inner pane integrated in the optically transparent area (22). According to the present invention, the thermoplastic interlayer comprises a second zone (12) delimited by the optically transparent area where the laminated glazing has a value of infrared transmission TIR1 higher than the value of infrared transmission TIR2 of the first zone (11) for the working wavelengths of the optical device.

Disclosed herein are methods for making asymmetric laminate structures and methods for reducing bow in asymmetric laminate structures, the methods comprising subjecting the laminate structures to at least one thermal cycle comprising cooling the laminate structures to a first temperature near or below room temperature and heating the laminate structures to a second temperature near or below the lamination temperature. Also disclosed herein are laminate structures made according to such methods.

The present invention employs a polyimide film, which has a coefficient of thermal expansion (CTE) that is a negative number at a temperature equal to or greater than 350° C., as a debonding layer for separating a flexible substrate and a carrier substrate, and thus can easily separate a flexible substrate from a carrier substrate by using a detaching phenomenon caused by a difference in residual stress between the flexible substrate and the debonding layer after a high-temperature process for producing an element on the flexible substrate. Therefore, the present invention can separate the flexible substrate without causing chemical or physical damage to the element formed on the flexible substrate, thereby minimizing problems that may occur during a stripping process.

The invention relates to a method for theiiiially stable joining of a glass element to a support element, wherein the glass element has a first coefficient of expansion and the support element has a second coefficient of expansion differing from the first coefficient of expansion. The method thus comprises a step of attaching an intermediate glass material to the support element, wherein the intermediate glass material has a third coefficient of expansion which substantially corresponds to the second coefficient of expansion. In addition, the method comprises a step of local heating of the intermediate glass material in order to join the glass element to the support element via the intermediate glass material.

A multilayer glass stack for a vehicle windshield with improved durability is described. The multilayer glass stack includes an external-facing glass layer, an internal-facing glass layer, and an adhesive interlayer positioned between the external-facing and internal-facing glass layers. The external-facing glass layer may include borosilicate and/or does not include soda lime glass. Methods of manufacturing the multilayer glass stack are also described.

Embodiments of a laminate including a first curved glass substrate comprising a first viscosity (poises) at a temperature of 630° C.; a second curved glass substrate comprising a second viscosity that is greater than the first viscosity at a temperature of 630° C.; and an interlayer disposed between the first curved glass substrate and the second curved glass substrate, are disclosed. In one or more embodiments, the first curved glass substrate exhibits a first sag depth that is within 10% of a second sag depth of the second curved glass substrate. In one or more embodiments, the first glass substrate and the second glass substrate exhibit a shape deviation therebetween of about ±5 mm or less as measured by an optical three-dimensional scanner or exhibit minimal optical distortion. Embodiments of vehicles including such laminates and methods for making such laminates are also disclosed.

Disclosed herein are embodiments of a borosilicate glass composition having a unique fracture behavior. The borosilicate glass composition may be incorporated into a glass laminate including a first glass ply and a second glass ply. The second glass ply may comprise the borosilicate glass composition.
