A Crash Course on Solar Heat Gain Coefficient

What Is Solar Heat Gain Coefficiency?

In layman’s terms, solar heat gain coefficient (SHGC) refers to the measurement of how well a product (windows and doors in particular) is able to block heat from the sun. SHGC is expressed as a value between 0 and 1, with the lower number indicating a better performance against unwanted heat gain. When the temperature starts to rise come the warmer months, doors and windows with low SHGC are extremely useful in keeping passive heating at bay.

On the other hand, doors and windows with higher SHGC levels are a better choice for homes that are in areas with a colder climate. Your preferred home exterior and roofing company can help determine which type of products are suitable for your home.

SHGC Requirements

Homes in regions that experience colder climate, such as Michigan, can benefit more from doors and windows with higher SHGC levels, as these products retain heat better. The type of glazing plays a role in how well a window can manage solar levels. Apart from having a higher SHGC, the window glazing recommendation for homes in cold climates should also have a low U-value which is the rate of heat transfer through a structure divided by the temperature difference in the building.
