The name of insulating glass

Insulating glass becomes more and more popular in modern tall building, especially for it characteristics of energy saving (known as reduce heating transmission), sound proof, and colorful color. It is the national regulation to install insulating glass in some countries; of course, more and more countries will regulate to use insulating glass for sure. In order to reduce the building energy consumption and environment pollution, insulating glass plays an important role.

However, do you know what is insulating glass?  How many names does it have?

Let’s see what from Wikipedia: “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 gas filled space to reduce heat transfer across a part of the building envelope”.

In a word, two glass, one air gap between them.  An insulating glass unit commonly consists of two (sometimes three) panes of glass separated by a spacer material and sealed together at the edge. The insulating airspace is filled with air or a noble gas, such as argon or krypton inside.

The equipment machines manufacturers usually name it as “insulating glass unit(IGU)”, while it is called “double glass” by most of the house owner.
