The Difference Between Window SHGC and U-Value

Understanding the features of windows is essential before deciding what to purchase for your home. In this post, we discuss window SHGC and U-value and how they can affect your choices for your window installation project.

Definition of SHGC

SHGC stands for solar heat gain coefficient and measures the amount of solar radiation that passes through glass or window frames and enters the home. A lower SHGC value is recommended to block out heat in homes located in warmer climates, while a higher value is better for properties in colder climates.

Definition of U-value

U-Value is a measurement of the rate of heat transfer through windows, frames and walls. A lower U-value is generally better and more energy-efficient because it means less heat can escape your home through the windows.

Comparison of SHGC and U-value

SHGC and U-Value have different benefits depending on the climate. SHGC gives you an idea about the amount of heat entering your home, while U-Value measures the rate at which heat escapes through windows. That said, it’s important to consider your local climate and environment so that you can make an informed decision when purchasing replacement windows for your Maryland Heights, MO, home.
