Double Pane Windows for Your York Region Home


What Is a Double Pane Window?

A double pane window, 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). Twice as efficient as a single pane window, IGUs are designed to reduce both energy loss and outside noise, such as street traffic. IGUs keep warm air indoors during heavy winters and cool air during humid summers, keeping your home quieter all year long.

How Are Double Pane Windows Created?

Single pane windows do not have air pockets; heat passes through glass more readily than air.

The air pockets in an IGU reduce the window's conductivity resulting in a better-insulated home. The twin panes are held in place with a spacer made of moisture-absorbent material called a desiccant. The entire unit is sealed to prevent the inner air chamber from escaping. Glass Doctor offers IGUs with argon or krypton gas in the air space and Low-E glass to further improve the window's insulating properties. Learn more about glass types on our "All About Glass" page.

Why Choose Double Pane Windows?

Homeowners who opt to build new construction homes with double pane windows or replace single pane windows in existing structures experience many benefits immediately after installation, including:

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.
  • IGUs 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.

When Should I Replace My Double Pane Windows?

Over the last two decades, IGUs have become the standard window option for new construction. However, many homes in America were built in the 1980s, according to the American Housing Survey. Homes built before or during the 1980s are more likely to have single pane windows or IGUs that have aged past their usefulness. If your windows aren't energy efficient, your HVAC system makes up the difference at your expense. Warning signs your double pane windows have outlived their usefulness include:

  • A milky appearance to the glass
  • Condensation forming between the panes
  • Distorted or broken panes

Windows account for 25 percent of residential heat loss. If your windows are in disrepair, it's critical to seek a solution. Should you upgrade your windows? Try one of these DIY efficiency tests to see if your home windows are as efficient as they could be.
