Glazings comprising first and second channel-section glazing elements are described. The first and second channel-section glazing elements are arranged to define a cavity in which is located an inner glazing element comprising a glass glazing element, in particular a soda-lime-silica glass sheet, channel-section glazing element or sheet of rolled glass having at least one fire polished edge. The inner glazing element divides the cavity into at least two spaces to improve the thermal and/or noise performance of the glazing. By using low emissivity coatings on one or more major surfaces of one or more of the glazing elements, the thermal performance may be further improved. Mechanical performance may be modified by the particular type of inner glazing element used. It is possible to retrofit existing glazings to improve the thermal and/or noise performance thereof.

A process for manufacturing a light armored curved laminated glazing intended to be fitted in an opening of a transport vehicle suitable for the mass-production fitting of a curved laminated glazing containing two glass sheets, wherein use is made of at least three constituent curved glass sheets of such mass-produced curved laminated glazing containing two glass sheets, including both sheets from one and the same such mass-produced curved laminated glazing containing two glass sheets, which have been previously bent together.

An armor system configured to be coupled to a frame surrounding a window in a vehicle or other structure, such as a building. The armor system may be configured to provide any desired ballistics protection rating. The armor system includes a ballistics-grade armor panel and at least one insert embedded in the ballistics-grade armor panel. The insert extends around at least a portion of a periphery of the ballistics-grade armor panel. The one or more inserts may be configured to reduce the parasitic weight of the armor system.

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. The second glass ply may have a coefficient of thermal expansion of less than or equal to 5.1 ppm°/C. A combined thickness of the first glass ply and the second glass ply may be greater than or equal to 3.7 mm and less than or equal to 6.0 mm, and a ratio of the second thickness to the combined thickness is greater than or equal to 0.825. The second glass ply does not fail when the first major surface is impacted by a Vickers diamond impactor at an impact energy of 0.25 Joules.

Some embodiments of present disclosure are directed to a micro-perforated glass or glass-ceramics laminate, comprising a first substrate laminated to a second substrate by a first polymer interlayer, wherein the first and the second substrates are independently selected from glass or glass-ceramics, and a plurality of micro-perforations, each of the plurality of micro-perforations extending through the first substrate, the first polymer interlayer, and the second substrate. Some embodiments are directed to methods of forming such micro-perforated glass or glass-ceramics laminates.

The present disclosure relates to bullet-resistant laminated glass having at least three sheets of glass. One of the sheets of glass faces the impact side as a cover sheet, and one sheet of glass is formed as a closure sheet facing away from the impact side. Between the cover sheet and the closure sheet, one or more intermediate sheets are disposed, these sheets of glass being connected to each other by composite layers. The composite layers are formed by flexible and dimensionally unstable films and/or cast compounds. The composite layers do not consist of polycarbonate, polyurethane or polymethylmethacrylate. In order to prevent splinter output on the rear side, this glass composite has a closure sheet on the rear side consisting of thermally or chemically prestressed glass.

A head-up display device that is to be mounted in a moving vehicle and enables an occupant in the moving vehicle to view a virtual image based on a reflected image of S-polarized light in a projection section, the head-up display device including: an image projector configured to apply projection light including S-polarized light; and the projection section on which the projection light is to be projected. The projection section includes laminated glass including a first glass plate defining a surface of the laminated glass on which the projection light is to be incident, a second glass plate defining a surface of the laminated glass from which the projection light is to be emitted, and a half-wave plate disposed between the first glass plate and the second glass plate. The first glass plate and the second glass plate each are formed from a glass composition containing silicon oxide, iron oxide, and an alkali metal oxide. At least one of the first glass plate or the second glass plate has a thickness of 0.3 mm to 3 mm, a total iron oxide content in terms of Fe.sub.2O.sub.3 in the glass composition of 0.2% by mass to 2.0% by mass, and a FeO content of 0.1% by mass to 0.5% by mass. The half-wave plate has visible light transmittivity and is configured to transmit light with an a* value of −2.5 to 4.5 and a b* value of −1.0 to 7.0 in a CIE color system. The reflected image is formed on a surface of the first glass plate which is to face an inside of the vehicle. The second glass plate is configured to emit from a surface thereof which is to face an outside of the vehicle the projection light converted to P-polarized light.

Electrochromic device laminates and their method of manufacture are disclosed.

It is now possible to economically produce, in series production, automotive glazing that has complex small radii feature lines (30). Such feature lines (30) are desirable as they can improve the stiffness of the glazing as well as contribute to the overall aesthetic and differentiation of the vehicle, allowing body lines to blend into and continue in the glazing. However, traditional automotive laminating methods do not lend themselves well to this type of product. Typically, the offset between the mating surfaces of the laminate must be very uniform. Such uniformity is difficult to achieve when producing small radii features. Rather than bending multiple layers with small radii feature lines that can be nested and subsequently laminated using standard plastic automotive interlayers, the invention makes use of a two part method for laminating, a dry lamination process and a wet lamination process, which requires only that the feature lines (30) be present in the outer glass layer (201).

A hurricane-resistant laminated pane comprises a first sheet of thermally strengthened glass having a thickness in the range of from 2 to 24 mm, a second sheet of chemically tempered glass having a thickness in the range of from 0.3 to 1 mm and a surface compression of at least 100 MPa, and a polymer interlayer adhered between the first sheet and the second sheet. A process for making such a pane and a window comprising such a pane are also disclosed.
