Insulated Glass consists of two or more glass window panes separated by a space to reduce heat transfer. A window with insulated glass is commonly known as double glazing or a double-paned window.

Insulating glass units (IGUs) are typically manufactured with glass in thicknesses from 3 to 10 mm (1/8" to 3/8"). Thicker glass is used in special applications. Laminated or tempered glass may also be used as part of the construction. Most units are produced with the same thickness of glass on both panes but special applications such as acoustic attenuation or security may require different thicknesses of glass to be incorporated in a unit.

Our industry-leading, IGCC-certified LiSec production line is fully-automated and has the capability to generate a silicone and polysulfide secondary seal. Our silicone seal dramatically increases the strength of the unit, while the polysulfide seal prevents fogginess and other moisture-related issues in between panes.
