Investigations of optical and surface properties of Ag single thin film
... Metallic thin films, such as silver, gold etc. exhibit high optical reflection over a wide optical radiation spectra that make them suitable for the use as optical mirrors. For this purpose the thin film should be continuous what can be achieved when a coating is at least 50 nm thick. Another requir ...

Insulated glazing
Insulated glazing (IG), more commonly known as double glazing (or double-pane, and increasingly triple glazing/pane) is double or triple glass window panes separated by a vacuum or other gas filled space to reduce heat transfer across a part of the building envelope.Insulated glass units are manufactured with glass in range of thickness from 3 mm to 10 mm (1/8"" to 3/8"") or more in special applications. Laminated or tempered glass may also be used as part of the construction. Most units are manufactured with the same thickness of glass used on both panes but special applications such as acoustic attenuation or security may require wide ranges of thicknesses to be incorporated in the same unit.
