What is the Energy Star rating system?

Energy Star is a government organization which monitors the energy efficiency of products and provides ratings for products, so that the consumer gets what they pay for. In general, an Energy Star energy rating is provided for windows based of the following factors:

  • Solar Heat Gain Co-efficient
  • U-factors
  • R-values
  • Visible Transmittance
  • Air leakage
  • Condensation resistance
  • Overall product quality

To gain a better understanding of rating values and energy efficiency, see our guide on replacement window ratings.

What is the window u-factor?

The u-factor is an energy efficiency measurement which measures how well the window insulates the space through reduction of heat transfer or heat loss.

What is the window r-value?

The r-value relates to the window’s ability to retain heat through insulation.
