The quick answer is there’s no real consensus among remodeling professionals on the issue. According to Brandon Erdmann, president and founder of HomeSealed Exteriors, LLC, “One company says triple pane is the only thing they sell, and the next company says it’s not worth it and suggest double pane windows are the way to go.” So what is the truth? From single, double to triple pane, does it really matter? And are triple pane windows really worth the additional cost?
The bottom line is this – triple pane windows are worth the additional cost if you plan on living in your house for anywhere from ten to twenty more years. That’s how long the cost of the third pane will take to give you energy savings that equal their cost. Or if you just hate anything remotely close to a cold draft in the winter, go for the triple pane window as extra insurance against the cold air seeping inside.
The thing is, triple pane windows with their three panes of glass, do a better job than double pane windows on preserving energy within your home. But, the third pane doesn’t really make that dramatic of a difference. With that said, we highly recommend double pane windows over single pane windows if you live in a colder climate. The Canadian government agrees and actually requires homeowners to use double pane windows, at a minimum, because they are so much more efficient than single pane windows.
“A window is not just a piece of glass anymore. It’s a piece of technology,” Joan Maisonneuve a policy manager with the Canadian Home Builders’ Association-Alberta told the Calgary Herald.
According to Glen Janiszewski, Director of Marketing Ply Gem Canada, windows installed today are completely different than windows installed 20, 30 or 40 years ago. The windows manufactured today by Simonton, owned by Ply Gem, are far more energy efficient. “The majority of heat loss is going to go through the glass,” Janiszewski told the Calgary Herald, which is why windows went from single pane sliding glass in the old days to double pane and now triple pane units.
Also, Low E coatings applied to Simonton windows significantly boost energy efficiency and we also use argon gas between layers of gas to further cut down on heat loss.
