Commonly known as double glazed unit (DGU) or insulating glass unit (IGU), this glass configuration comprises of two panes of glass that are separated by a spacer and filled with air or argon gas that seeks to increase insulation efficiency, cut down solar and radiant heat. These qualities can be further enhanced by adding frit and other materials.

DDG host a series of insulated glass ranging from reflective, solar control, pyrolytic up to triple low e soft coatings to reduce incoming solar heat. They are available in different tints to suit require building aesthetics.
