What Is Insulated Glass?

Insulated glass consists of two or more panes of glass separated by a spacer. The spacer creates a sealed cavity between the panes, which is typically filled with air or insulating gas such as argon.

A specialized sealant is applied around the spacer to create an airtight and watertight seal. This sealed space helps reduce heat transfer between the inside and outside of your home, improving energy efficiency and indoor comfort.

The complete assembly of glass panes, spacer, and sealed cavity is called an Insulated Glass Unit (IGU).

At Glasso Fairfax, we specialize in replacing broken, damaged, or fogged insulated glass units without replacing the entire window frame or sash—saving you time and money.

A cool, metal oxide coating is applied to clear or tinted glass, so that the appearance and performance are the same regardless of glass thickness. Low-e glass brings out the best that technology has to offer for improving your views and comfort! Low-E glass typically costs about 15% more than ordinary glass, but it reduces energy use by as much as 30-50%, by using most of the heat gain in winter but keep the harmful UV rays out during the summer, and when used in insulated glass units – can have even better benefits. For hot climates, low-E coating should be applied to the outside pane of glass. If the windows are designed to provide heat energy in the winter and keep heat inside the house typical of cold climates, the Low-E coating will maximize benefit by being on the inside pane of glass. Low-e glass is recommended by many energy efficiency experts as a result of high performance combined with aesthetics. Most newer windows come with Low E Glass. At Glasso Fairfax, we make sure the replacement glass matches your existing whether it’s Low E or standard clear glass.

Tempered Glass

For uses that require added strength, Tempered Glass is installed. Tempered Glass is created by a heat treatment that is unique as well as a quenching process both done to increase the strength up to 4 to 5 times that of annealed glass. When subjected to stresses outside its capacity, Tempered Glass merely disintegrates into numerous small pieces, significantly decreasing the danger of serious injury. Tempered glass is for use where glass is most susceptible to human contact such as doors, windows located close near floor, on landings of the stairway and enclosures for shower or tub. Your safety and the safety of your family, guests, and visitors is the responsibility we take very seriously.
