How to Determine a Good SHGC Rating for Your New Windows

Choosing new windows for your home involves more than just aesthetics; understanding their energy performance ratings, particularly the solar heat gain coefficient (SHGC), can play a significant part in your decision. To help you out, Krech Exteriors shares more insight.

Understanding SHGC: More Than Just Numbers

SHGC measures how much solar radiation — or heat — a window lets into your home. A higher SHGC means more heat gain, while a lower SHGC results in less. This rating is crucial for energy efficiency; in colder months, windows with a higher SHGC can supplement your home heating, while in warmer months, a lower SHGC can help keep your home cool.

Choosing the Right SHGC for Your Home

The ideal SHGC for your windows depends largely on your climate and your home’s orientation. In cooler climates like Minnesota, windows with a higher SHGC on south-facing walls can be beneficial for utilizing passive solar heat gain. However, for east- and west-facing windows that get strong morning and afternoon sun, a lower SHGC may be preferable to prevent overheating.

How SHGC Impacts Your Utility Bills

Choosing windows with the right SHGC can make your home more energy-efficient and lower your utility bills. In the winter, windows with a higher SHGC can reduce your heating costs by letting in more solar heat. Conversely, in the summer, windows with a lower SHGC can reduce your cooling costs by blocking more of the sun’s heat.
