Endorsed by the government, ENERGY STAR is a symbol indicating energy efficiency. In the past two decades they have helped millions of businesses and families save electricity usage, money on energy costs, and reduce greenhouse gas emissions
The energy star rating of windows and doors is measured using the Canadian Standards Association (CSA) A440.2 standard.
Energy performance is based on the following values:
U-Factor: Measures the rate of heat transfer through a building component such as a window or door.
Solar Heat Gain Coefficient: Measures how much of the suns heat can pass through the product.
Energy Rating (ER): A value that shows the balance between U factor ratings, solar heat gain coefficient and air leakage.
R-Value: Measures a materials resistance to air flow.
Visible Transmittance: Measures how much visible light passes through a window or glass door.
Centre of Glass Reading: The energy efficiency of the glass of the product.
