The Importance of SHGC Rating to Your Windows

It’s important to be proactive when trying to make your home more energy-efficient. Your roof, windows and doors all contribute to your home’s energy performance. Have you heard about the solar heat gain coefficient (SHGC) in connection with your energy-efficient windows? 

What Is SHGC?

SHGC is a standard that estimates the solar radiation that passes through glass. Energy-efficient windows typically have SHGC values. The rating is expressed as a number between 0 and 1. A low rating of SHGC means less solar heat is transmitted. This means that the windows insulate your home well and have good shading ability. The ideal SHGC rating for windows is 0.25 or less.

However, your window’s optimal SHGC rating depends on your home’s climate, location and shading outside. It’s best to learn about the effect of your home’s structure on your SHGC. If your SHGC is not optimized, your home is at risk of overheating. This may cause serious damage to your interior and even increase your energy bills.

Energy-Efficient Windows

It’s important to replace your traditional windows and learn more about energy efficiency. Modern windows with SHGC values act as protective barriers against solar heat. They work better for insulation in your home. This helps your home’s energy performance and saves you money in the long run. 

Older windows are costly. They force your heating units to overwork and cause interior issues. When replacing your windows, look for a reliable local window contractor to help you with the process.
