Thin-Film Thermal Conductivity Measurement Using Microelectrothermal Test Structures and Finite-Element-Model-Based Data Analysis
... [9], [20]. In the 3ω method, an alternating current is applied to the heater/sample/sensor structure, and a lock-in amplifier is used to detect the current or voltage output signal at a particular frequency [1], [11], [14]. Another well-known method is based on steady-state joule heating with dc cur ...

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.
