Understanding the U-Value of a Window Assembly

 In Windows

The use of energy-saving windows can help homeowners reach their energy-efficiency goals. While there are various aspects that contribute to a home’s energy efficiency, the windows are one of the most significant. To help you boost energy-efficiency levels through your windows, it helps to understand the U-Value of a window assembly.

Window Assembly

What Exactly is the U-Value?

Windows are rated by both U-Factors and R-Values. Manufacturers use the former to rate the insulative value of windows, while the latter is indicative of the energy efficiency of the insulation installed in other areas of your home. These include the roof, walls and floors.

How Do You Determine the U-Factor?

The U-Factor refers to the overall energy efficiency of the entire window assembly, from the glazing, to the window frame, down to the spacer. The most energy-efficient windows available on the market are those that have a higher U-factor for the entire assembly than that of the center of the glass. Make sure to look into it when choosing energy-saving windows.

U-Factor in Different Climates

As with other components of your home, you’ll need to consider your local climate before choosing which products to buy. Windows with .30 or less are ideal for cold climates while .60 is the ideal number for hot climates. A .35 rating is ideal for northern and central regions that have need for both heating and cooling, however.

Understanding the U-value of a window assembly is essential for quantifying the energy efficiency of your options. Make sure to factor it in when shopping for replacement windows and ask your trusted contractor about these ratings to get the best results.
