Dual Glazing

Double glazing is the glazing process in which a window is made with two panes of glass with a space between them. In many cases, air is trapped between the panes and forms a layer of insulation. Before the unit is sealed, a drying agent is added to ensure that no moisture is present inside the finished glass unit. Double glazing substantially stops heat loss, and the cost of the windows will often pay for itself very quickly in the money institutions save from heating bills.
