Written by: FTC Oury Group
Many years ago, windows were made with a single pane of glass. These windows, now called single pane windows, were the best technology available for homeowners to allow natural light into their homes. Single-pane windows had many downsides. They were energy inefficient, drafty, and easily allowed sound into the house.
Over time, industry professionals discovered that adding additional panes of glass could improve a home's energy efficiency and the window's performance. Today, homes are available with double and triple panes of glass to provide better value, improved functionality, and improved energy efficiency.
If you're seeking window replacement for your home, you'll have a decision to make. Double pane windows, or triple pane?
Making an informed decision can be a challenge. Both window types have benefits. Understanding the differences between double-pane and triple-pane windows can help you decide which one is right for you.
At FTC Oury Group, we perform window installation for homeowners. We're here to help you make smart decisions throughout your window installation. Here's what you need to know.
What are Double Pane Windows?
Double pane windows are windows that have two panes of glass, with a pocket of air or gas in between. Modern double-pane windows are typically made with ultra-energy-efficient glass. Sometimes, these panes of glass have a Low-E coating to reflect heat and help keep your home at a stable, comfortable temperature. Double-pane windows are the most common type of window found in modern homes.
What are Triple Pane Windows?
Triple-pane windows have three panes of glass. Between the outer panes and the inside pane, there are two pockets of air or gas to provide insulation. Triple-pane windows are the most energy-efficient windows in modern homes.
Compared to double-pane windows, triple-pane windows weigh more. The extra layer of glass adds to the heft of the window. For some homeowners, the extra weight is worth the improved energy efficiency, while for other homeowners, double-pane windows are better.
Double Pane vs Triple Pane Windows: Main Differences
So, which type of window is best? There are many factors to consider before making your decision.
Cost
Double-pane windows are made from less material. With one fewer pane of glass, they're easier to make and cost less than triple-pane windows. For a homeowner on a budget, double-pane windows are a more affordable option.
Many homeowners choose double-pane windows over triple-pane because the additional cost of buying triple-pane windows can impact the ROI. If you're hoping to sell your home, the additional value from installing triple-pane windows may not be very high.
The added cost of triple-pane windows should also be taken into consideration when calculating how long you'll take to make back your money. Double-pane windows are more energy efficient, as are triple-pane windows. Both can save you money on your home's energy bills.
Triple-pane windows can help reduce your energy costs by more than double-pane windows, but triple-pane windows cost between 50% and 200% more. If one of your goals is to save money on utility bills, it's important to calculate how long you'll take to pay back your windows and start saving money. Having this information can help you decide which type of windows to install.
Energy Efficiency
Triple-pane windows are about 20% more efficient than double-pane windows. For some homeowners, this improved energy efficiency is plenty of reason to install triple pane windows. For other homeowners, the excellent energy efficiency is enough, and not worth the additional cost.
Noise Reduction
Double-pane windows and triple-pane windows both do a very good job of blocking sound. Triple-pane windows block more sound than double-pane windows, but unless you live in a very noisy place, you will not notice much difference between the two window types. If noise reduction is your goal, some types of glass are better at blocking sound than others. Talk to your window dealer and installer before choosing windows for your home.
Style
Double-pane windows are the most popular window types available. Triple-pane windows are less popular and often available in fewer styles. For a full range of options, consider double-pane windows.
Condensation and Seal Failure
Triple pane windows are less likely to produce condensation, although both window types are condensation-resistant.
At the same time, triple-pane windows are more vulnerable to a problem called seal failure. The space between panes of glass on double and triple-pane windows should stay tightly sealed to prevent the window from becoming foggy. As windows age, they become more likely to experience seal failure. Triple-pane windows are more vulnerable to seal failure simply because there are more seals to break.
Location
The location of your windows within your home can affect their exposure to the elements and impact the likelihood of condensation or seal failure. Windows on the north side or in shaded areas, which receive less direct sunlight, may experience more condensation. For these locations, triple-pane windows can be a better choice due to their superior insulation and resistance to condensation.
On the other hand, for windows located in areas with more direct sunlight or less exposure to moisture—such as living rooms or bedrooms—double-pane windows may provide sufficient performance while being more cost-effective. It's important to consider where your windows will be installed when deciding between double and triple-pane options to ensure optimal energy efficiency and long-term durability.
Which One's Better for You?
The decision to buy double or triple-pane windows can be very personal. For some homeowners, the additional energy savings and noise reduction is worth the extra cost. For other homeowners, the money savings and availability of more styles make double-pane windows a far better value.
