A laminated transparency includes a first ply having a No. 1 surface and a No. 2 surface. A second ply is spaced from the first ply and has a No. 3 surface and a No. 4 surface, with the No. 2 surface facing the No. 3 surface. A polymeric interlayer is positioned between the first and second plies. At least one failure strip is incorporated into the interlayer to provide a predetermined failure orientation for the transparency.

The invention provides a method of processing glass that involves forming a flexible gel layer on a flexible glass sheet to create a glass-gel sheet; rolling-up the glass-gel sheet into the form of a roll; placing the roll in a dryer; and drying the flexible gel layer so as to form a flexible aerogel layer. Some embodiments provide a glazing unit that includes a glass-aerogel sheet located between first and second panes of the glazing unit, where the glass-aerogel sheet includes a flexible glass sheet and a flexible aerogel layer on the flexible glass sheet. In such embodiments, the first and second panes each have thicknesses that are greater than a thickness of the flexible glass sheet. Other embodiments provide a glass assembly having a flexible aerogel layer on a flexible glass sheet, with the flexible glass sheet being laminated to a glass pane.

Methods of modifying a property of a prefabricated film are provided. The prefabricated film is exposed to a solvent to modify a property of the prefabricated film to provide a modified film. In some embodiments the solvent comprises a plasticizer. In some embodiments, the property comprises ionic conductivity. In some embodiments, the solvent is part of a solution comprising a reactive compound. In some embodiments, the reactive compound comprises an alkali metal salt.

A method for producing laminated glass for automobile windows includes heating and bend forming two glass plates; and bonding together the two bend-formed glass plates via an interlayer film, wherein, the method further includes scratching that is performed on a concave surface of at least one of the two glass plates, after the bend-forming.

The present invention relates to drying processes for composite films comprising a polyvinyl acetal on a carrier as well as to composite films and polyvinyl acetal films obtained in such processes.

A laminated glass for vehicle use is prepared from raw materials including a first glass plate, a second glass plate, and an interlayer material. The first glass plate and the second glass plate have different compositions. The difference between temperature Tp1 and temperature Tp2 is smaller than or equal to 50 C. The temperature Tp1 is defined as a sum of a transition point temperature Tg1 of the first glass plate and a first temperature compensation value Tb1. The temperature Tp2 is defined as a sum of a transition point temperature Tg2 of the second glass plate and a second temperature compensation value Tb2. The temperature Tp is defined according to the following general formula: Tp=Tg+Tb.
