Should I Choose Double Pane Windows or Triple Pane Windows?

When deciding between the different glass options for your replacement windows it’s important to consider the pros and cons for triple-pane windows and double-pane windows.  The decision between glass types should be based on your preference of sound transmission, performance, and how much you’re willing to spend.  This post will focus on the pros and cons for each factor.

Double Pane Windows vs. Triple Pane Windows

Sound Transmission

When it comes to the ability to block out extra noise, triple pane windows can perform better than double pane windows, however it’s a very small improvement.  There are certainly more important factors to consider when deciding between triple or double pane windows.  If your main reason to purchase new windows is to block out extra noise, I would suggest looking into other options such as laminated glass.

Performance

There is certainly a difference when it comes to comparing which window will perform the best.  The three main factors of measuring the performance of windows are to compare the R-value (ability to resist heat flow), and the SHGC (Solar Heat Gain Coefficient).  Triple pane windows will almost always have a lower SHGC rating than double pane windows, a lower SHGC rating mean the window will do a better job at keeping out heat producing rays.

When evaluating R-values it’s important to know that higher R-values will help to keep your home cool during summer months and warmer in the winter months.  When triple pane windows take the place of double pane windows it could help to decrease heating bills.

Cost

On average triple-pane windows will cost around to 10-15% more than double-pane windows, however you’ll have the most energy efficient windows for your home.  With window efficiency constantly improving there are great opportunities to lower your heating bill with triple pane windows.  With Maryland winter  weather becoming consistently colder each year, triple pane windows could be beneficial to homeowners in the long run.

 


The decision of which window type is best for your home is ultimately a decision based on which factors mean the most to you.  If your primary focus is to have the most energy efficient home, then triple pane windows are your best option.  If you’re looking for a lower performing window that costs less, then you would be looking for double pane windows.
