Finding the right windows and doors that are a good fit for your home can help make it more energy-efficient. This blog explains what SHGC ratings are so you can make a good purchase decision for your home should you need window replacements.

What Is SHGC?
Solar heat gain coefficient (SHGC) is the measure of how much solar energy a window lets through. It’s measured on a scale from 0 to 1. The lower the number, the less solar heat your windows will let in; therefore, having an SHGC rating closer to 0 can help reduce your cooling costs during the summer. Ultimately, it helps you make sure you get energy-efficient windows that reduce your costs down the line.
What Are Ideal SHGC Ratings?
Ideal SHGC ratings depend on the climate and location of your home. For areas with warmer climates, you’ll want to look for window products that offer low-emissivity glass. This type of glass will help keep in the heat during cold winters while blocking out unwanted ultraviolet light at other times throughout the year, ensuring optimal energy efficiency all year round. Generally, an optimal SHGC rating would be 0.25 or less.
The types of windows you choose also affect their SHGC rating, regardless of how low or high it measures. Windows made from fiberglass and vinyl are known for having higher energy-efficient properties. Meanwhile, double-hung units offer an excellent balance between cost and quality performance. If you like your home a bit warmer, get New Jersey windows with an SHGC rating of 0.35-0.60 to allow more natural solar heat inside your home.
Benefits of Ideal SHGC Ratings
Choosing replacement windows with ideal SHGC ratings comes with a host of benefits that go beyond energy savings. You can enjoy increased comfort from reduced drafts and air infiltration when your windows and doors are sealed correctly. In addition, well-optimized glass helps prevent condensation build-up during colder months, lowering the likelihood of mold growth and reducing maintenance costs.
With an understanding of ideal SHGC ratings, you can be sure you’re choosing energy-efficient products that come with all the benefits mentioned above.
