Double glazing is a term for the assembly of windows where the window is made of two or three panes of glass which have been hermetically sealed together. Double glazing in windows produces many desirable effects.
Advantages of double glazing
Double glazing maximizes the insulation properties of the windows. Environmentally and economically, double glazed windows, or as there are sometimes called, insulated glass windows, keep in the heat and save energy in heating a home.
Because of the high cost of energy, triple pane, or triple glazed windows have become more popular. Double glazing refers to the window construction itself, but these types of windows with double glazing usually come are complete units – sash, frame, or in a curtain wall.
As people replace windows in their home, old six by six single pane windows are usually replaced these days with insulated windows with double glazing or triple glazing. Sometimes tinted glass is used in double glazed windows in order to regulate the degree of light allowed inside.
