Double-Pane Vs. Triple-Pane Windows:  FAQ Guide

Oct 24, 2019 3:27:39 PM / by Greg Martell

With up to 40% of a property's annual energy budget dedicated to heating and cooling costs, anything that you can do to improve a businesses' energy efficiency won't just help it become more sustainable — but it will result in more disposable income as well. 

One of the best ways to improve a property's energy efficiency is by investing in new windows. There are many factors that must be considered when it comes to new windows, but one of the biggest questions is regarding window type. On this note, one of the biggest decisions home architects, developers, or business owners will often have to make is deciding between double or triple-paned windows. 

The main difference between each window type is how many panels of glass they contain. The more panels of glass in a window, the better its durability, noise reduction and energy efficiency properties. In this post, we'll tackle some of the frequently asked questions when it comes to double versus triple-pane windows.

How Much Money Can You Save Switching from Double to Triple-Paned Windows?

It's estimated that property owners that upgrade to triple-paned windows over double-paned windows can save 3% on heating and cooling costs. This is all thanks to the additional panel of glass, as it's able to further reduce drafts, and prevent cool air from escaping in the summer and warm air from escaping in the winter.

A 3 percent increase in efficiency may not seem like a notable improvement, but when you consider how much is spent on heating and cooling costs each year, it adds up. Additionally, the more windows you have in your business, the bigger the long-term return on investment becomes from going with triple-paned windows.

Pro Tip: Insulated glass units made with low-e glass can help you save even more on energy costs. 

It's also worth noting that triple-paned windows have other benefits that might not be obvious from a money perspective. The biggest is noise reduction, thereby making triple-paned windows a better option for businesses located near railroad tracks, busy streets and highways, and other areas that produce lots of noise.

What's the Difference Between a Triple-Paned Window and Triple-Glazed Glass?

The biggest difference between coated and non-coated glass is the ways in which it interacts with the sun. Glazed windows have a tendency to reflect the energy of the sun, thereby preventing heat buildup inside a property. 

Triple paned windows still do a good job of maintaining designated indoor temperatures, but glazed windows can give a home or business some extra protection, especially in areas that receive heavy amounts of sunshine each day. 

Furthermore, glazing can also help reduce condensation, meaning that indoor humidity levels are less likely to fluctuate.

What are the UV Considerations for Triple Versus Double-Paned Windows?

The greater the number of panels of glass in a window, the better job they'll do when it comes to safeguarding a property from the sun. In this respect, triple-paned windows are better than double-paned windows. 

However, laminating the glass can also help reflect additional UV rays, adding another layer of protection.

Which is a Better Selection for Being in a Natural Disaster-Prone Area of the World?

Double-paned and triple-paned windows are both durable, but the more panels of glass in a window, the greater its durability. In this respect, triple-paned windows are more durable and better suited for areas more prone to natural disasters than their double-paned window counterparts. 

The same is true if you're worried about theft or burglary, as triple-paned windows are the better choice due to their enhanced durability. Additionally, similar to UV protection, laminating the glass can assist with fortifying the glass and inhibits something from breaking through, helping it to stay in place.

Should a Business Have Double or Triple-Paned Windows?

That depends on several factors. For instance, a business owner should ask themselves the following questions:

  • How many windows does the facility have?
  • Is the facility located in an area prone to natural disasters?
  • How much do you spend on annual heating and cooling costs?
  • Does the building always seem drafty?
  • Does your business store products that are sensitive to high or low temperatures?
  • Are you looking for enhanced office security?

If the building has a lot of windows and spends a lot on heating and cooling costs each year, then the ROI from upgrading to triple-paned windows (if it doesn't already have them, that is) will be greater. It may be possible, however, to mix and match double and triple-paned windows on the property. 

Since triple-paned windows do a better job of shielding the building from the sun's energy, you might find that triple-paned windows are more suitable for areas of the building that receive heavy sun and double-paned windows are adequate everywhere else.

Additionally, triple-paned windows are more secure and won't break as easily as other types of windows when laminated glass is incorporated in the makeup.
