There’s more to choosing wood and vinyl windows than just considering the type of material and overall aesthetics. It also involves determining the energy efficiency, as indicated in the products’ energy performance ratings. One of these ratings is the solar heat gain coefficient (SHGC), and we’re here to discuss its importance when selecting replacement windows.
SHGC is an energy performance metric that measures how well a window resists unwanted heat gain from the sun. It is expressed as a value between 0 and 1 — the lower the SHGC, the less solar heat a window transmits, helping to keep your home cooler during hotter days. An SHGC rating closer to 1 indicates more solar heat transmission, offering natural warmth during colder months.
So, what is a good SHGC rating for replacement windows? The answer depends on several factors, including your local climate and the orientation of your windows. For example, if you live in a cooler region with less exposure to sunlight, you’d want windows with a higher SHGC rating to optimize solar heat gain. Meanwhile, homes in warmer climates would benefit from windows with a lower SHGC rating for maximum heat blockage.
The SHGC isn’t the only rating you need to know when choosing replacement windows. The U-value, for instance, measures the windows’ insulating capabilities, particularly their ability to keep heat from escaping your home. Visible transmittance refers to the amount of visible light windows can admit indoors. Like the SHGC, these ratings must be taken into account when it comes to your home’s daylighting needs and comfort levels.
