Triple Pane Windows vs. Double Pane – Buying Guide
Adding new energy efficient windows to your house will not only increase your home’s curb appeal and resale value, but the right windows will also improve the air quality and temperature control inside your home. When it’s time to replace your old or damaged windows with newer, more energy efficient models, there are many options to consider including how many glass panes to get. The most common are double or triple pane windows. If you are wondering which type is better suited for your home, we can help take the guess work out of your decision.
What are Double and Triple Pane Windows?
The word pane means the sheet of glass in the window. Double pane windows have two sheets of glass while 3 pane windows have three sheets. Each pane of glass is separated from each other with securely sealed spacers and high quality sealers to ensure moisture and unwanted air flows cannot seep through.
Because triple pane windows have an additional layer of glass, they are considerably heavier than double pane windows. Because of their design and structure, some older houses might not support the weight of the 3 pane windows. Always seek advise and recommendations from a professional window installer first when replacing your old single pane windows with triple or double pane glass.
Triple pane windows will reduce noise only slightly better than double pane glass because they have an extra layer of glass and insulation. When tested, the difference between triple and double pane glass windows and noise reduction was only 0.5 decimals. For most homeowners, noise levels should not be a big factor when choosing triple or double pane windows.
However, if you live in a high noise area, triple pane windows only will likely not be enough to reduce the noise volumes in your area. For really noisy places, like near an airport, high traffic area, or construction zones, you will need specialized soundproof glass windows to decrease the noise levels. If you need windows that reduce loud noise volumes, talk to us at CanPro Windows and Doors about noise reduction glass and frame options to maximize your replacement window’s sound reducing qualities.
Triple Paned Insulation
To fill in the spaces between the panes, gas is used because it is a better insulator. Argon or Krypton gases are most commonly used between the window panes because they are odourless, colourless, and non-toxic. While Argon is cheaper and more readily available, Krypton has better insulating qualities.
Each glass pane is also coated with a low-emissivity or Low-E coating to improve its energy efficiency. All triple and double pane windows in Canada are made with this Low-E coating.
R Value, also called R Factor, measures the amount of heat resistance in the glass or how much external heat can seep into your home. When comparing double pane vs triple pane windows, two window panes have an R Value of 3 to 3.8 whereas the triple pane windows R Value is 7 to 8.
U Values or thermal insulation measure heat loss trough the frames of your window. Triple pane windows have better thermal insulation than double pane glass so less escapes from your home.
How are Triple Pane Windows Better Than Double Pane?
Triple pane windows are naturally more energy efficient than two pane windows and are better designed to maintain your home’s air quality and interior temperature. Over time, 3 pane windows can reduce your energy bills by an average of 2-3% annually.

If you are replacing an old window, with a newer, more energy efficient window the same size, you will not require permits or additional construction labour and materials to install your new windows.
However, if you are planning to add bigger or smaller triple pane windows to your existing space, you will need a permit because you will be making changes to the structure of your home. Up or downsizing your windows will also increase the cost of your triple pane window installation.
