What Are the Benefits of Double Glazed Windows?
Double-glazed windows have a number of advantages over single-paned windows. For a single pane of glass to be an effective insulator, it would need to be very thick, making it look too bulky. A better option is to have double-glazed windows--two panes of glass separated by a spacer bar, which provides a gap of air or nontoxic gas (such as argon or xenon) between them. This gives a layer of insulation that results in a variety of benefits.

Controls Temperatures
-
The air or gas between the two panels of a double-glazed window is a poor conductor of heat, and thus acts as an insulator. During colder seasons, the inner pane of the window warms up, but the heat remains in the air gap, preventing the heat from being conducted to the outer panel and escaping. During warmer seasons, the outer pane warms up, but the air gap creates a barrier that stops the heat from warming up the inner pane and entering the house. The controlled temperatures allowed by double-glazing make it more comfortable to stay inside the house.
Reduces Energy Consumption
-
Because of the insulation offered by double-glazed windows, air conditioning units and residential heating systems do not have to work as hard, as the indoor temperature is better regulated. This reduces energy consumption. Energy-saving windows usually have an energy saving label that indicates the energy-saving rating of the window. The higher the window's energy rating, the more energy it can save.

Improves Security of Home
-
Double-glazed windows increase the security of a home. It is harder for intruders to break two layers of glass as opposed to a single glass panel. Most double-glazed windows also have secure locks or handles with built-in locking devices for additional security. Safety glass or security glass options are also available, with the panels made of laminated, toughened or annealed glass. For homeowners who have these security double-glazed windows, it is important to have an escape route in case of emergencies, as the glass will not easily break on impact.
Reduces Noise From Outside
-
The double panes of glass and the insulation between them provide a more effective barrier to sounds coming from outside the house than a single pane of glass, giving residents a living environment that is more peaceful and quiet.
