Energy Star Certified Windows

 Energy Star Certified Windows


ENERGY STAR® is the symbol of high-efficiency Canadian products. The mark identifies the top energy performers on the market today based on strict technical specifications for energy performance. ENERGY STAR products save energy without any reduction in performance. You may have seen the symbol on other products in your home or at work, such as refrigerators, washing machines, furnaces, computer monitors, televisions, and lightbulbs. ENERGY STAR qualified products are in the top 15 to 30 percent of their class for energy performance. Saving energy saves you money and reduces your impact on the environment. The ENERGY STAR label is administered by Natural Resources Canada (NRCAN).

Scheel Window & Door is a leading manufacturer of high-efficiency windows. Scheel is a qualified ENERGY STAR participant in the category “windows, doors and skylights manufacturers.” Scheel vinyl windows are ENERGY STAR-certified and manufactured to provide exceptional value, high energy savings, and maximum protection from the extreme temperature swings typically experienced by the residents of Eastern Ontario.

New Energy Star Ratings

Effective Feb 1st, 2015, new and higher standards were introduced to the ENERGY STAR program in Canada. The energy ratings shown below reflect the new rating. Scheel casement, awning, and fixed windows exceed the standard ENERGY STAR High Efficiency Rating by as much as 60%.


We conducted additional tests by an independent laboratory, see the exceptional results in the chart below:

The U-Factor is a measure of the rate of heat loss and is expressed as a number between 0 and 1. The lower the number, the slower the rate of heat loss.

Solar Heat Gain Coefficient (SHGC) measures incident solar radiation and is expressed as a number between 0 and 1. The lower the number, the less solar radiation is transmitted, absorbed, and released inward.

Energy Rating (ER) is a formula that accounts for the U-factor, air leakage, and potential solar gain. The higher the number, the higher potential energy savings.

Zones are climate zones based on the the average annual temperature in a region. They were previously divided into zones A, B, C, D, and are now Zone 1, 2, and 3. Ottawa and the Ottawa Valley are in climate zone 2.

ENERGY STAR Window Features

ENERGY STAR-certified windows prioritize energy efficiency. Scheel high-efficiency windows are manufactured with the following features to maximize performance and energy savings:

  • • Double- or triple-glazing with a sealed insulating glass unit
  • • Low-e glass
  • • Inert gas (argon or krypton) in the sealed unit
  • • Low-conductivity or “warm edge” spacer bars
  • • Insulated frames, sashes, and door cores
  • • Strong air tightness

Together, these features reduce energy use in a typical home by 7%-16%. Upgrading the high-efficiency windows saves the typical homeowner $126-465 a year when replacing single-pane windows, and $27-$111 when replacing double-pane, clear glass windows.

Energy-efficient windows make homes more comfortable in cold weather and hot temperatures alike, save you money as a homeowner, and help the planet by slowing greenhouse gas emissions. ENERGY STAR windows increase comfort, reduce exterior noise levels, reduce condensation, and filter more UV rays than traditional windows.
