Double Pane Windows


Double Pane Windows Installation and Replacement

Double pain windows, also known as an Insulated Glass Unit or IGU, is a window with two panes of glass separated by a vacuum or gas (like argon). These windows are twice as efficient as a single pane window. Double pane windows are designed to reduce both energy loss and outside noise, such as street traffic. IGUs keep warm air indoors during heavy winters, cool air in during humid summer and reduce noise from entering your home year round.

The Science Behind Modern Units

Double pane windows or IGUs keep your home insulated during the harsh summer and winter months. Single pane windows do not have air pockets; heat passes through glass more readily than air. The air pockets in an IGU reduce the windows conductivity resulting in a better-insulated home. The twin panes are held in place with a spacer made of moisture-absorbent material called desiccant and the entire unit is sealed to prevent the inner air chamber from escaping. To further improve the insulating properties of the window, A&E Glass offers IGUs with argon or krypton gas in the air space and Low-E glass.

Should You Choose Double Pane Windows?

The benefits of installing double pane windows include:
  • A reduction in your home’s energy bill; some units save homeowners up to 50 percent in energy expenses.
  • Reduce carbon footprint.
  • Reduce noise pollution.
    • This quality is especially valuable to our clients who live in busy, urban areas.
  • Double pane windows prevent 25 percent of the sun’s heat from entering your home, reducing glare and UV damage to carpeting, drapes and furniture
These benefits are seen to varying degrees based on the number of windows replaced and other energy saving measures employed.
