So, let’s look at the biggest differences between double-pane and triple-pane replacement windows so you can decide which is better for your home.
3 Key Differences Between Double-Pane and Triple-Pane Windows
The number of panes on your replacement windows directly affects the energy efficiency, cost, and durability of the windows.
Because the glass of a window makes up about 95% of the entire window, it is crucial to choose the right glass option for you.
Now, the difference of one pane on your windows may not seem like it would largely affect the window overall. But, the three key differences in double and triple-pane windows are:
1. Energy-Efficiency
The window glass is the biggest factor that affects the energy efficiency of your windows. What affects the energy efficiency of your glass is the glass type, added coatings, and the number of panes.
Think of it like this. When it’s extremely cold outside, we layer up. The more layers we wear, the more protected we are from the outside elements and the warmer we are.
The same goes for your windows. The more panes on your windows, the more your home is protected from harmful UV and infrared rays, and the better the internal temperature of your home is regulated.
- Double-pane windows make your windows two times more energy efficient than single-pane windows.
- Triple-pane windows make your windows three times more energy efficient than single-pane windows and 1.5 times more efficient than double-pane windows.
While a large part of the energy efficiency of your windows is the glass type, the number of panes will also increase the overall efficiency of them as well.
So, if you want the most energy-efficient windows to provide maximum protection for your home, triple-pane windows will be the best choice. However, double-pane windows are still an energy-efficient option and are the standard choice for most replacement windows.
2. Durability
After considering the difference in energy efficiency between double and triple-pane windows, the next largest factor to consider is durability.
The durability of your windows refers to how well it stands up against weathering and everyday use, as well as how long they last. But, when specifically looking at the durability of window panes, we’re talking about the overall strength of the window glass.
Let’s look back at the example of layering up. If you wear three heavy jackets and someone punches you right in the stomach, you will have more protection than if you only wore one or two jackets, right?
Of course, no one wants to be punched in the stomach, even if you are protected by multiple layers. Unfortunately, that doesn’t mean it can’t happen.
Now compare the scenario to your new replacement windows and how many panes your windows have.
The more panes your windows have, the stronger they are, and the better they protect your windows and home against external forces. A triple-pane window will be harder to break than a double-pane window, meaning multi-pane window glass can improve your home security.
The durability of window glass depends on how the glass is made, what type of glass it is, such as tempered or laminated, and the number of panes.
So, if you want windows that are stronger than average and will be harder to damage and break, you will want to upgrade your windows with more panes for added security.
3. Cost
The final factor to consider between double and triple-pane windows is the cost. How much your new windows will cost is always top of mind for most homeowners, and rightfully so. A window replacement project is a large investment.
Any addition or customization you add to your new windows will increase the cost just as it does with any product. The more custom and unique you design your windows, the more cost increases.
So, naturally, triple-pane windows are more expensive than double-pane windows. The cost difference between the two types of windows is about $150 for one 3 ft. x 5 ft. window.
While the cost addition for one window is not astronomical, you must consider how it all adds up to the total cost of your project.
To help you determine whether double or triple-pane windows are right for you from a cost perspective, you must outline your perfect budget for you.
Considering how you want your windows to perform, how long you want them to last, and how you want them to look will allow you to have realistic expectations for your window replacement project and create the right budget for you.
Double-Pane Vs. Triple-Pane Windows: Which Is Best For You?
Now that you know the three key differences between double and triple-pane windows, you understand how energy efficiency, durability, and cost differ depending on the type of window you want.
While the difference in one pane on replacement windows may not seem grand, the difference in details is crucial to consider to choose the best window type for you.
Double-pane windows are less expensive than triple-pane windows. While they are energy-efficient and durable (depending on the glass type), triple-pane windows are 1.5 times more durable and energy efficient because of the added pane.
- If you want an energy-efficient window but don’t want to break your budget with unnecessary customizations, double-pane windows may be the better choice for you.
- If you want a window with better energy-efficient properties and increased strength, triple-pane windows will be more what you are looking for.
Finding the right replacement window for you all depends on your goals. Consider how you want your windows to perform in terms of durability and energy efficiency, what you want them to look like, and how much you want to pay.
As you consider how many panes are right for your windows, you also want to consider what glass type or glass coatings may be right for you and what you’re looking for.
This article will outline five common types of glass coatings for replacement windows, like Low-E, tinted, and security coatings, so you can understand your options and whether a glass coating is right for you.
