Insulated double glazing glass for building glass window tempered glass sheet

Insulated glass is a new heat and noise insulation building material which has other many features- energy saving, safety, antifogging, etc.  Insulated Glass is hermetically sealed combination of two or more pieces of glass separated by a dry air-space. The space itself can be filled with dehydrated air, or with a special gas. Insulating glass is mainly used in building curtain wall, window, ceiling, and so on. Low-e Insulated glass is also called Insulated Glazing (IG), more commonly known as double glazing or double-pane, and increasingly triple glazing/pane are double or triple glass window panes separated by an air or other gas filled space to reduce heat transfer across a part of the building envelope.
