Finding the right windows for your home is vital. As you look into the many options available, one of the metrics you should consider is a window’s solar heat gain coefficient (SHGC) rating. Installing windows with the right rating will help maintain comfortable indoor temperatures while providing natural light in your home. Hiring a window installation company knowledgeable about SHGC ratings will help ensure you get what you need for your home.
SHGC is the amount of solar radiation that passes through a window and how much it gets absorbed by it. It is typically expressed as a number between 0 and 1, with higher values representing more heat entering your home. The lower the rate, the greater potential for energy efficiency compared to windows with higher ratings.
SHGC ratings are calculated from multiple tests with different energy performance standards designed specifically for each climate zone. With these standards in place, manufacturers can compute an expected rating for their products in various climates before manufacturing them.
Experts use a tool known as an integrating sphere spectrophotometer. It performs precise measurements on multiple samples taken at different temperatures over an extended period. This is to accurately determine a replacement window unit’s SHGC percentages.
Remember, it helps to work with a local residential window services professional when figuring out the ideal SHGC ratings for your home. This ensures you get what’s best based on your needs and preferences. Two things must be considered when checking out different window ratings.
