As winter approaches you’re probably noticing more of a draft coming from your old windows. If they haven’t been replaced in many years, chances are you’re using only single or double pane windows.
So what’s the deal with triple pane windows? These are the most advanced windows on the market with three panes of glass, instead of two or just one. Each of the panes has a spacer included to keep the distance between each pane uniform. The windows are also sealed airtight with pockets of gas filling the space for insulation.
As technology in replacement windows advances, triple pane has become more of the norm than a luxury product.

Benefits of triple glazing
There are a few core benefits of triple pane windows.
Greater noise reduction. Triple pane windows are the best on the market and decreasing outside street noise from humans, traffic, nature, and more. If you live in a city, this could be a major lifestyle boost.
Better insulation. Triple pane windows may pay for themselves in the end thanks to advanced insulting properties. Your energy system will need to work less to keep the inside temperature regulated. No more drafts, and no more high energy bills. Sounds good to us!
Cost savings. In cold regions, such as New England, triple pane windows can save 2 to 3 percent of your heating bill, compared with double-glazed windows. That will add up to cover the extra cost for the windows in about 20 years.
Reduce condensation. Triple glazing will reduce condensation, which will allow you to maintain a higher indoor relative humidity in cold weather. If you don’t want to pay for triple pane windows throughout the house, get them for the north- and east-facing rooms, where you’ll get the biggest payoff.
Added value. Triple glazed windows add value to your home and you can recoup some of the cost when selling your home.
Double pane vs. Triple pane windows
OK, so now you know that triple pane windows are a bit more expensive than the other options available, especially the common double pane windows. So what’s the difference and how do you decide?
First, how long will you be in your home? It’s important to consider the cost outlay now vs. the savings over time. Staying for 20 plus years? Triple pane. Moving out soon? Double pane.
There are many falsehoods you’ll hear about triple pane, too. For instance they aren’t too heavy to fit in a traditional window frame. No worries there. Triple pane windows will operate with the same ease as double pane windows. They also will not have seal failure more often than double pane. All new windows will come with a warranty that will cover you in the event of any type of failure.
In fact, triple pane windows have a better U-factor than double pane and 20-30% better on energy efficiency — that’s a substantial margin. Triple pane will also have better visible transmission figures. While these statistics will vary according to where you live and the exact windows your home has, you can find out more about your windows’ energy efficient performance by checking out their Energy Star rating.
They will also have better SHGC ratings as they tend to have two surfaces coated with a low-e coating. These coatings will leave you with a lower visible transmission rating meaning it will typically be darker in a home with triple pane windows.
Are these increases in efficiency worth the trade off of increased cost and decreased light? Only you can decide that, but with the cost difference likely being lower than you might expect more folks are picking triple pane options.
Lastly, the cost difference between double pane and triple pane windows is not too bad. Triple pane windows cost an average of $100 more per window than double pane.
