There’s more to purchasing new windows than simply choosing an attractive aesthetic. Although appearances matter, the R-value and U-value of the unit are key to your comfort. By focusing on these figures, you can make an appropriate decision that best meets your needs.

What Is the R-Value?

The R-value of a window refers to its resistance to the flow of thermal energy. Many elements of residential structures have an R-value, from the walls to the insulation. The greater this figure, the more insulating capacity the window has—and the more energy you will save as a result. But be aware that when you’re shopping for the right piece for your home, the R-value is assigned to the glass pane and not the actual assembly. That matters because it’s easy to confuse this figure with the U-value.

What Is a U-Value?

The U-value, conversely, is a measurement of the window assembly as a whole, and how much heat energy is transferred into the home through it. This includes its frame, the hardware, glass, and glaze. The figure is the opposite of the R-value. If you have a unit with a high R-value, the window’s U-value will be lower—which means it’s highly efficient at resisting heat flow to help you maintain a comfortable home and save on your monthly energy costs.

How Should You Choose?

In addition to focusing on the window’s efficiency as a whole, you also need to make sure that it’s made with low emissivity, or low-E, glass. This is a clear coat designed to reflect heat without impacting the quality of light. When a unit has a minimal low-E value, its R-value is greater, and its U-value is lower. This equates to a window that is extremely efficient at keeping heat inside your home when it’s cold outside and making sure it stays out in the summertime.
