Materials of insulated glass unit?

Glass panes:

An insulating glass unit consists of at least two panes of glass. Except normal float glass, other types of coated and laminated glasses may be used depending on the application to enhance the performance of the unit.


Frame, or the spacer bar, is the material used to separate the two glass panes in an insulated unit. Usually made of aluminium and filled with desiccant, it holds the unit together, provides thickness and mechanical resistance, and plays a key role in ensuring optimum performance of the unit.


Desiccants are used to remove any moister trapped within the IG unit. The different types of desiccants are silica, molecular sieve and zeolites.


Sealants are very important in the manufacture of insulating glass. They are easy to handle, efficient, safe and environment friendly. They are good adhesives, elastic and durable.

Filling (gas):

Dry air, gas like argon, vacuum are the three different types of fillings filled between the glass sheets .

What is insulating glass?

Insulating Glass, often called insulated glass, double glazing, is a combination of two or more panes of glass spaced apart with a aluminum spacer bar and hermetically sealed with a primary and secondary sealant to form a single unit with one or more air spaces in between glass panes. Insulated glass units improve the thermal performance, thus significantly reducing heating and air-conditioning costs. Insulating glass units also reduce interior condensation in cold climates, and increase comfort near windows, thus maximizing the usable interior space.

IG units can be fabricated to meet energy saving requirements, and sound control requirements. IG units can be designed to reduce heat loss and solar heat gain entering the building, with a minimal reduction of visible light transmittance.

What is the most common types of insulated glass?

The most common types of insulated glass are those with multiple panes. Most insulated glass units are double-paned units, though some are triple-paned.
