Are you wondering if triple-pane glass windows worth the cost? Selecting which type of window is best for your home can be difficult at times.

Triple-pane windows are typically worth buying if they reduce your cost of living year after year. They can reduce the size of your heating bill by three to four percent if you live in a colder region of the United States, while also offering noise reduction.

Also, triple-pane windows are quieter and more comfortable than double-pane windows.

Below, I will go through the differences between triple and double-pane windows. I will thoroughly explain the best reasons to buy triple-pane windows.

Plus, I will answer some of the major questions regarding triple and double-pane windows.


Comparing Two-Pane Windows Versus Triple-Pane Windows

The attitude “more is better” is important when you want to compare triple-pane windows to regular two-pane types. It does not matter if you are comparing the energy efficiency, the ability to block out noise, or the weight of the two types of windows. The bottom line is that the third layer of glass does indeed mean something.

Two-pane windows involve placing two panes of glass together and inserting a filler of krypton or argon gas in the middle of the panes. Triple-pane types are made using triple glass layers that have two layers of the gases in between each pane.

Argon gas cost less, and it lessens the transfer of temperature. Krypton gas has more density than argon, which means it works even more efficiently to reduce the transfer of temperature.

Plus, krypton gas maximizes energy-efficient qualities. That is what most triple-pane window brands use it in their construction.

Depending on the window brand that you buy, the merchandise will use a spacer system that maintains the glass panes at the right distance from each other. Plus, they will create a tighter seal that keeps the gas from escaping. Installing a decent spacer system gives you a house that is quieter.

The third section of glass causes triple-pane windows to weigh more and be thicker. They are typically one-inch thick, and two-panes windows are sold as triple-quarters of an inch model, seven-eighths of an inch model, or a one-inch thick model. If the window fits properly into a well-made frame made of fiberglass or vinyl, then its weight or thickness does not matter to most people.


Increase Your Energy Efficiency with Triple-Pane Windows

The third pane of glass makes a difference in how the window performs. Windows come with an NFRC sticker noting the following characteristics:

  • R values are the amount of heat resistance
  • U factors are the amount of heat transferred to a component
  • Low E, or low emissivity, is the designates window was treated with a metal coating which both reflects and emits heat energy
  • SHGC (Solar Heat Gain Coefficients) is the window’s ability to regulate solar heat gains and the amount of solar energy that can pass through it
  • VT values (Visible Transmittance.) are the sunlight amount in daylight that floods through the window, despite if it is tinted

The top windows, which are ENERGY STAR-compliant, include a combination of high R-values and VT levels. Plus, they tend to have low U-values, E coatings, and low SHGC.

Two-pane windows can decrease heat loss by half, while triple-pane windows can lower the heat loss by 20 percent to 30 percent. Triple-pane windows add improvements in thermal conductivity, plus the U-Factor is lower for them.

Both two and triple-pane windows have a low emissivity, or otherwise called low-E, and a metal coating reflecting and emitting heat energy.

Triple-pane glass windows have two coatings of the low-E material which will make your house somewhat darker on the inside.

However, your house will offer more comfortable. Reflective and tinted films will produce a similar effect.

Also, when it comes to energy efficiency, windows that do not open, such as insulated and foam injected frames, are better than ones that do open.

Remember, the smaller the temperature differential between the inside and outside of a house, the smaller the heat transfer that will occur.


Decrease Noise with Triple Pane Windows

Yes, it is true that triple pane windows reduce noise when compared to dual pane windows. In fact, we wrote a whole blog post on this subject here.


Final Words

Triple-pane windows are priced higher than two-pane windows unsurprisingly. If you buy them from a window business that is trustworthy, then they should cost about one hundred dollars more for each window.

The difference in price has decreased significantly over the years. However, when you must choose between them, you should factor in the prices, how much your energy savings will be, and how long you will be living in the house.
