A Word About Solar Heat Gain Coefficient

Home window replacement can leave property owners feeling flustered because of the terminology that one must understand to make an informed purchase.  One such piece of jargon related to replacing your home’s windows is solar heat gain coefficient (SHGC).  Allow us to break down this term into easy-to-understand language.

What is Solar Heat Gain? In layman’s terms, solar heat gain is the volume of the sun’s energy that converts into heat as it filters through your home’s windows.  A higher solar heat gain rating equates to a more sizable amount of sunlight allowed into a home.  The highest SHGC rating is one and the lowest SHGC rating is zero.

Does Solar Heat Gain Prove Problematic in a Home?  In the winter months, solar heat gain can be advantageous because it can raise the temperature of a room without having to adjust a home’s thermostat.  However, in the summer months, solar heat gain can be problematic because it can elevate a temperature of a room unnecessarily.  The SHGC rating of the replacement windows you select for your home should be reflective of the climate you live in.  In southern states, a lower SHGC rating is preferable because of how warm air temperatures tend to be throughout the year.  Having windows with a higher SHGC can be advantageous in the Midwest because of how cold winter temperatures can be.

Infinity from Marvin® Windows Have an Exemplary Solar Heat Gain Coefficient:  

Window Placement Throughout the Home: A reputable window contractor should be able to easily explain their SHGC rating they suggest for various areas of your home.  For example, a low SHGC rating often makes sense in eastern and western facing rooms within a home because they are exposed to a prolonged period of sunlight in the summer months.  The utilization of a low solar heat gain window can lessen cooling costs without making a heavy dent on heating costs.  In the winter months, when heat is desirable, high solar heat gain windows work well on south-facing walls and will lower heating costs without making a dramatic increase on a home’s cooling costs.

"We are part of an HOA. We had Lindus out to replace the windows in our townhome. They did a great job in the pre-sales, helps us select window design, and delivered the windows as ordered. I was very impressed with the installers. they were very professional, friendly, and showed a great deal of care for both our home and for keeping us safe during this time of COVID. Installation was top notch, the interior and exterior match wonderfully. great craftsmanship.  After having the windows for a number of months now, We really appreciate the quality and the noticeable change in heating and cooling."

"We had four SeasonGuard windows installed to replace 4 original windows in our home.  The quality of the product and the quick, and exceptional installation was great. They matched the original trim beautifully.  Even though we experienced a one week delay due to exceptionally cold weather on the first scheduled date, the follow-up was well done.  From start to finish, a great company to work with. We love our new windows.  Quiet, draft-free and well done."
