A glazed unit of curved form includes a first glass sheet with a thickness of less than 1.6 mm, a second glass sheet having a thickness of less than 1.6 mm, an intermediate film with a thickness of less than the thickness of the thinnest glass sheet of the glazed unit and arranged between the first glass sheet and the second glass sheet, the glazed unit further including a seal encapsulating all the sides of the glazed unit.

Thin-film devices, for example electrochromic devices for windows, and methods of manufacturing are described. Particular focus is given to methods of patterning optical devices. Various edge deletion and isolation scribes are performed, for example, to ensure the optical device has appropriate isolation from any edge defects. Methods described herein apply to any thin-film device having one or more material layers sandwiched between two thin film electrical conductor layers. The described methods create novel optical device configurations.

A method of manufacturing a window includes: preparing a glass substrate laminate which includes preparing a base substrate, alternately disposing glass substrates and adhesive layers on the base substrate, and disposing a cover substrate on the glass substrates and the adhesive layers alternately disposed; and cutting the glass substrate laminate, where the adhesive layers include a potassium nitrate (KNO.sub.3) particle and an adhesive resin. This method makes it possible to effectively manufacture an ultra-thin glass substrate used for a window.

Methods of manufacturing electrochromic windows are described. Insulated glass units (IGU's) are protected, e.g. during handling and shipping, by a protective bumper. The bumper can be custom made using IGU dimension data received from the IGU fabrication tool. The bumper may be made of environmentally friendly materials. Laser isolation configurations and related methods of patterning and/or configuring an electrochromic device on a substrate are described. Edge deletion is used to ensure a good seal between spacer and glass in an IGU and thus better protection of an electrochromic device sealed in the IGU. Configurations for protecting the electrochromic device edge in the primary seal and maximizing viewable area in an electrochromic pane of an IGU are also described.

Lightweight ballistic glasses are provided that provide effective protection from ballistic attack while also being lightweight enough for use in armored vehicles and aircraft. In addition to other embodiments, a multilayered lightweight ballistic glass is provided that meets the CEN 1063 Level BR7 standard while having a weight of no greater than about 155 kilograms per square meter (kg/m.sup.2), and a total thickness of less than about 75 mm.

A fire resistant glazing is provided that seeks to avoid the issue of air gaps forming between a glazing and a frame into which the glazing is placed, a method of manufacturing the fire resistant glazing and the use of same. The fire-resistant glazing includes an intumescent edge mass located at least partially between the first sheet of glazing material and the second sheet of glazing material and which is suitable for, and may be installed within, a glazing frame.
