High-quality windows have a long lifespan, and they perform well in various conditions. Plus, their energy efficiency features help maintain comfortable indoor temperatures all year round. To know whether a window meets your energy efficiency requirements, look for its solar heat gain coefficient (SHGC) and U-value.
In this post, Timberland Exteriors discusses the difference between SHGC and U-value.
SHGC is the amount of solar radiation that passes through the window glass. A high SHGC rating indicates that the glass absorbs more heat, while a lower SHGC rating means less heat can penetrate the window.
U-value refers to the insulating capacity of the window glass. A higher U-value means outside heat can affect indoor temperatures more, while a lower U-value means heat from outside isn’t felt much indoors.
The recommended SHGC and U-value for your windows depend on your location. High SHGC generally works best in colder regions as it reduces the demand for heating. Meanwhile, low SHGC is ideal for homes in warmer climates as it reduces the need for cooling.
Regarding U-value, a low number is generally recommended for any climate. Good insulation benefits homes in warm and cold regions.
A window will remain energy-efficient if it’s properly maintained. That said, make sure to inspect and clean your windows regularly. Do this twice a year and use the appropriate cleaning solutions. Furthermore, lubricate the mechanical parts to keep them operable and check for any gaps and cracks on the frame.
