Triple-glazed windows are a relatively recent innovation in window manufacturing. A triple-glazed window comprises three layers of glass set within a frame. In comparison, a single-glazed window has a single pane of glass, and a double-glazed window has two panes. Moreover, layers of argon or krypton gas separate the panes of triple-glazed windows to increase energy efficiency.


Triple-glazed windows are up to 50 per cent more efficient than double-glazed windows. The extra layer of glass creates an additional insulating barrier that double-glazed windows don’t have. The other layer helps keep indoor temperatures stable, keeping your home warmer in winter and cooler in summer. 


Another energy-efficient element of triple-glazed windows is low-emissivity (low-E) glass, which has a thin coating that reflects heat and the sun’s harmful UV rays. You can upgrade to double low-e giving two layers.


The layers of argon or krypton gas also contribute to superior energy efficiency. These gases are heavier and denser than air and minimize heat transfer through the panes. 


U-value measures heat loss in windows; the lower the U-value, the less heat loss the product permits. On average, a single-glazed window has a U-value of 5.6, while a triple-glazed window has a U-value of 0.8. The average U-value for our triple-glazed windows is 0.24.

The principal drawback to triple-glazed windows is that they cost more than double-glazed and single-glazed models. However, higher upfront costs can be offset by long-term energy savings.

Triple-glazed windows are also heavier than double-glazed and single-glazed windows and may be an unsuitable option if the existing structure provides inadequate support.


In addition to being energy efficient, triple-glazed windows offer the following:

Better security. The thickness of a triple-glazed window makes it difficult for vandals and intruders to break.

Improved soundproofing. Due to the extra glass panes and gas layers, a triple-glazed window is the most soundproof option.

Less condensation. Condensation in windows occurs when moist, warm indoor air contacts cold window glass.

Thanks to their low U-values, triple-glazed windows offer the most significant protection against condensation.

It’s a widely known fact that updating your home’s windows is a profitable investment. Not only does it up the curb appeal of your home, ultimately allowing you to sell it at a higher price if you decide to move, but new windows can also lead to decreased energy consumption and lower electricity bills. While the decision to upgrade your windows may seem like a no-brainer, there are still a few things you need to consider, one of them being whether you want the replacement glass to be double or triple paned. If you aren’t familiar with the differences between the two, don’t worry; here’s what you need to know


Low-emissivity coatings

Low-emissivity coatings are widely regarded as beneficial, as they do wonders for temperature regulation. They trap in heat during the winter, and reflect UV rays on sunny summer days, thereby preventing your home from overheating when it’s hot out.


Low-E coating is applied to both double and triple pane windows during manufacturing. However, having three panes is advantageous, because that extra layer of coating will amplify the window’s insulating ability. One coating is applied to one piece of glass even with triple glaze. This does not apply.


Argon gas

Inert gases, such as argon or krypton, are often inserted in the spaces between window panes. The gas has an insulating effect similar to a low-E coating, thereby preventing heat transfer between the outside and the inside.

Because triple pane windows result in two gaps between panes instead of just one, as is the case with double pane windows, they’ll perform more efficiently.


Sound proofing

If you’re frequently disrupted by noise from outdoors, choosing triple pane over double pane windows is definitely the right move for you. The added layer of glass will have a significantly greater effect when it comes to reducing unwanted noise.



As is to be expected, triple pane windows are more expensive than their double pane counterparts. However, since they’re more efficient insulators, they’re the better investment of the two. In the long run, triple pane windows will make up for their greater expense with elevated savings on your electricity bills.
