Performance Rating
Solar Heat Gain (SHGC)

the higher the SHGC, the number, the greater the solar gain

Let the sun shine in, or not. The Solar Heat Gain Coefficient (SHGC) measurement can help you achieve a desired increase or decrease in the amount of solar radiation (heat) passing through a window into your home.

Performance Rating
Energy Star (ER)

Although windows and doors don’t consume energy themselves, they can be a significant source of energy loss. If you're purchasing windows with energy efficiency in mind, the ER helps you make standardized product comparisons.

Performance Rating
Air Leakage (AL)

Air leakage (AL) is becoming an increasingly important factor when selecting energy-efficient windows and doors, especially for homeowners in cold climates like Ottawa. With rising energy costs and a focus on energy efficiency, understanding AL can help you choose products that reduce drafts and maintain indoor comfort. But what exactly is air leakage, and why should you care?
