Insulating glass is a glazed unit composed of two or more glass panes separated by spacers filled with dehydrated air or gas. The sheets are connected by a spacer, using sealants to reduce water vapor penetration. The whole unit is hermetically assembled by a secondary edge seal which gives structural robustness to the insulating glass. The spacer contains a desiccant which absorbs humidity from within the air space.

Insulating glass units use the thermal and acoustic insulating properties of a gas (or vacuum) contained in the space formed by the unit. They can provide good insulation without sacrificing transparency.

The most important function of insulating glass is to reduce thermal losses, which offers many advantages: lower energy consumption, perfect transparency by reducing the incidence of condensation on the warm air side and the possibility of using larger glazed areas without increasing energy consumption.

Apart from better thermal performance, the use of insulating glass units significantly increases noise isolation.

Characteristics:

Applications:
 Windows and Doors 
 Commercial Storefronts and Glazing 
 Refrigeration Units 
 Skylights

Insulating glass units can be assembled using different types of glass: regular float glass, laminated glass, low-e glass, heat-treated glass and etc. The choice of the glass applied determines the overall performance of the whole unit and may offer additional useful features.
