Will the increased efficiency of triple pane windows pay off for you? Triple pane windows are unquestionably better at keeping your home warmer or cooler in the appropriate season and can benefit you in other ways as well.
Understanding Triple Pane – Insulated – Windows
In triple pane windows, an extra pane of glass and an additional gas chamber between the panes improves window performance. While double pane windows can lower heat loss by 50%, triple pane models prevent even more heat loss. The less heat you lose, the less you must expend in energy costs.
Some vendors maintain that the more panes of glass at work, the quieter the home is inside. This has been disproven, as home expert Bob Vila notes. If sound proofing is your goal in upgrading your windows, you would get more sound reduction from a laminating treatment.
Energy Efficiency of Triple Pane Windows
You can depend on triple pane windows to provide better performance and potential energy savings, especially as indicated by U factors (heat transfer), and SHGC (ability to control solar heat gain.) In Northern climates, you should be most concerned with U-factor, while in the South, SHGC is the more important variable.
Improving U-factors is where the difference between panes of glass makes a big difference:
- Single pane windows have a U-factor of 1
- Double pane windows have a U-factor of 0.30
- Triple pane windows have a U-factor of 0.12
What Better Efficiency Means in Dollars and Cents
As energy efficiency is the wave of the future, triple pane windows are expected to become the norm for creating a comfortable home. As a homeowner, there are several things you need to weigh when you replace windows.
Triple pane windows are more costly to install; however, when you sell your home, you can expect to recoup up to 78% of your costs. While some companies overprice them and charge 40% more, you should realistically expect to pay at least 10%- 15% more than double pane windows.
With the increased efficiency of tripe pane windows, the Department of Energy says you can expect to see about 7% to 15% decrease in energy costs in very cold areas, and less in warmer climates.
Rebates Can Offset Costs
You may get some help paying for triple pane windows. To offset part of the cost of insulated windows, utility companies in most states offer increasing rebates the more efficient your windows are. Rebates vary by state, but in Utah, both the glass and the electric company offer rebates if your windows meet specific criteria. In general, the lower the U-factor of the window, the higher the credit. With a lower U-factor than double pane windows, triple pane windows usually qualify for a larger rebate.
