What You Need To Know About SHGC

Not only can your windows boost your home’s appeal, but they’re also one of the important light sources of your house. When choosing the perfect window that will best fit your home, you should be able to determine the ideal Solar Heat Gain Coefficient or SHGC measurement. 

What You Need To Know About SHGC

In this article, Kroll Construction discusses what you need to know about SHGC and how this can affect your home. 

What Is the Importance of SHGC?

Your glass window can absorb and redirect heat in three different ways: conduction, convection and radiation. The SHGC is the measurement of the solar radiation transmitted through a window that is absorbed and released into your home. The measurement ranges from 0 to 1, 0 being the least amount of heat allowed through a window, with 1 being the most.

Solar heat gain has its benefits and disadvantages. In the winter, it can provide free heating and warm your home during the day. However, it can also lead to overheating in the summer. For this reason, window and glass manufacturers control the desired solar gain or loss through different levels of tinting or coatings. 

How Can SHGC Measurements Help Me Choose a Window?

If you’re thinking of purchasing replacement windows, be sure to consider your area’s climate, the direction of the sun, and the shading conditions of your home to balance and maximize the potential benefits. If you don’t, your place might overheat, causing your cooling system to work hard to lessen the heat gain.

If you live in a warmer climate, you might want to consider a window with a low SHGC to keep your home cool and reduce energy costs. On the other hand, homeowners in colder climates can choose a window with higher SHGC for a warmer home, benefiting from free solar heat. You can also choose to buy a window with a Low-e coating as it can reduce the amount of solar heat that passes through the glass. Additionally, you can reduce the SHGC by using external or internal shading devices, such as pergolas, Venetian blinds or trees.
