Double Pane vs. Triple Pane Windows: Which is Better?


So, you’re due for a window replacement. It’s a normal part of almost every homeowner’s home improvement journey. But if you are just beginning your window replacement research, you might be confused as to which type of window is right for you.

Namely, should you choose double-pane windows or triple-pane windows?

For many of us, we’ve never even heard of these distinctions. However, they can make a huge difference to our home as a whole.

If you are struggling to understand the difference between double pane vs. triple pane windows, we’re here to help! Follow along with our handy guide to help you choose the perfect windows for your home.

What Is a Double-Pane Window? 🪟

Double-pane windows are characterized by having two panes of glass, usually separated by a layer of insulating gas. For years, double-pane windows have been the windows most frequently installed in homes. Compared to single-pane windows, they offer:

  • Superior noise reduction
  • Increased insulation
  • Increased energy efficiency

What Is a Triple Pane Window? 🤷🏽

A triple-pane window – as the name suggests – has an additional pane to help protect your home. This extra pane is also cushioned by a layer of gas to create extra protection for your home.

Which One Is More Expensive? 💰

When it comes to choosing whether double-pane or triple-pane windows are right for your home, your first concern is likely cost. After all, everyone wants to feel like they are getting a good deal!

Double Pane Windows Cost

Double-pane windows inevitably cost more than their single-paned counterparts. That being said, the price varies greatly depending on the style of window you choose. The average cost of a new double-pane window is around $130-$1000.

Believe it or not, most homes only have 8-10 windows. That means replacing all the windows in your home with double-pane windows will cost roughly $7,000-$10,000

Triple Pane Windows Cost

If you are looking to add triple-pane windows to your home, it is inevitably going to cost you more than a double-pane window would. Triple-pane windows cost $300-$1500 per window, depending on the size and style. When budgeting for your window replacement, don’t forget to factor in labor costs, as well!

Which One Has Better Energy Efficiency? ⚡️

Both types of windows are known for their energy efficiency. But which one is really better in an energy efficiency showdown? Here’s what you need to know.

Double Pane Windows

Double pane windows initially gained popularity in the market because they offered such great energy efficiency for the home. In fact, Energy Star themselves have found that a homeowner could experience up to a 30% increase in energy savings when switching to upgraded windows.

The layer of argon gas between the two sheets of glass is highly effective when it comes to insulating and lowering energy costs.

Triple-Pane Windows

If double-pane windows are effective at protecting your home from cold air seeping inside, triple-pane options are even more so.

Studies have shown that a triple-pane window can be up to 20% more energy efficient than its double-pane counterparts. Despite the fact that they are more expensive up front, many homeowners in colder climates find that triple-pane windows end up being worth the extra cost. Because they are so effective at preventing heat loss, you will eventually discover that your energy bill goes down, leaving extra money in your pocket.

Which One Has Better Noise Reduction?

Too much noise pollution can make your home feel anything but peaceful. If you’re looking for a window that will reduce noise pollution, here are some things to consider.

Double-Pane Windows

Double-pane windows offer a much better sound barrier than single-pane windows do. This is measured through a system called Sound Transmission Class (also referred to as an STC rating). This rating system measures how much sound is blocked by your windows or walls. Generally speaking, windows with one pane only have an STC rating of around 18-20. Multi-pane windows, however, rate much higher, with most double-pane windows achieving a 28-32.

Triple-Pane Windows

Installing triple-pane windows can be an excellent choice if you live in a high-traffic, noisy area. Most triple-pane windows come with an STC rating of at least 29. Some brands claim to reduce up to 52% more noise than a standard single-pane window.

Which One Is Best for Me? 👍

Are triple-pane windows worth the cost? Or would most professionals suggest double-pane windows to their customers?

The truth is a large part of it comes down to personal preference. If your main concerns are the price of your new windows, double pane windows may very well be the right choice for you. After all, they still offer you a good amount of energy savings and noise reduction.

That said, you cannot beat the superior benefits and costs of triple panes.

  • You’ll earn back your initial investment in energy savings.
  • Protect the privacy and peace of your home with sound reduction.
  • Triple-pane windows will help regulate your home’s temperature if you live in a climate with extreme weather.
