What Are Triple Pane Windows?
Triple pane windows—the most advanced windows on the market today—are made with three different panes of glass. As with double pane windows, each of the panes has a spacer around the edges to give them a uniform space between layers. A seal between each pane makes the windows airtight and allows for pockets of gas to fill the space for improved insulation.
The Benefits of Triple Pane Windows
Triple pane windows contain more layers of glass to separate your home from the outside, and they also contain insulating pockets for gas or air. Both of these qualities make triple pane windows better insulators than either single or double pane windows. That means you’ll spend less money heating and cooling your home.
More Sound Proof
Triple pane windows are more effective at keeping out sound than single or double pane windows. This particularly beneficial if you live in a city or some other noisy environment. For some, this advantage can be worth the extra cost of the windows on its own. Check out some of the best soundproof windows.
Because of their advanced insulating properties, triple pane windows are better at regulating your home’s temperature at a comfortable level. This affects your expended energy and monthly energy bills, but also your relationship to your home. For example, if you have a favorite spot next to the window in your favorite chair, single pane windows can limit your time here, but triple pane windows will allow you to stay comfortable and warm in your spot until you’re ready to leave.
Triple Versus Double Pane Windows
If you’re having trouble deciding between double or triple pane windows, you’ll need to consider the potential insulation improvements. Just take a look at double and triple pane windows and you’ll see that the U-factor (rate of heat loss) is better in the triple pane option, making them the better insulator.
Next, you’ll need to consider the difference in cost. Triple pane windows are a bit more expensive, although the amount of increased insulation versus the cost can more than pay for itself over time.
Choosing a Quality Spacer
Though the gas pockets between panes provide excellent insulation, heat moves through the spacers, which limits a window’s potential energy efficiency. If you’re buying triple pane windows, make sure to get a “warm edge spacer”. These are more effective at slowing heat down and, therefore, make your windows more efficient.
Getting an Upgraded Gas
Switching to a gas with a higher insulating factor—like argon or krypton—can make a noticeable difference in your window’s insulation. Argon gas is the most commonly used insulating gas because it’s clear, odorless, and most importantly, non-toxic.
Krypton has those same qualities, but it provides an even higher level of insulation. Triple pane windows provide two pockets for gas, so you can have them both filled with whichever gas you choose.
More Protective Coatings
If you’re shopping for windows, you may hear about low-e coatings, which are designed to reflect heat back into the home when it tries to escape. Since only one coating can be added to each section of glass, triple pane windows offer more potential layers to coat, meaning more insulative protection for your home.
Triple pane windows are modern upgrades to double pane windows. Both options offer marked improvements over single pane windows, and almost every style of window today comes with double or triple pane glass depending on your preferences.
