It’s not a mystery that can help make your home more energy efficient resulting in significant energy savings each year. However, what some of you might find interesting is the fact that replacement windows are considered one of the best return on investment when it comes to energy retrofits.

According to a recent study windows with a higher R value (inverse of the U value) are a better ROI than increasing insulation throughout the home or installing a solar system. Obviously there are some caveats to this blanket statement but it points out a consideration that many people have forgotten with all the talk about better performing insulation and cheaper solar systems.

Installing Replacement Windows

If you’re interested in in your home it’s important to learn about all the options and what will help you get the best ROI. By far the most important factor in increasing your ROI is purchasing replacement windows with a very low U factor (high R value).

Today that means stepping up to triple pane glass with Low-E coatings and Argon gas filling between panes. The slight difference in cost between double pane and triple pane (15% to 20% typically) is quickly offset by the energy savings. An average double pane window has a U factor of 0.34 (R = 3) while a triple pane window typically has a U factor of 0.25 to 0.20 (R = 5). As you can see the cost of 20% can be quickly offset with a U factor almost 3 times better.
