MAKE AN ENERGY EFFICIENT CHOICE FOR YOUR DOORS AND WINDOWS PURCHASE

While researching replacement windows and doors, you've probably heard of terms such as ENERGY STAR® and climate zones.

Since January 1, 2020, Natural Resources Canada (NRCan) has increased the requirements of the ENERGY STAR® program, with a new version of the criteria, version 5.0 commonly known as; ENERGYSTAR 2020. The major change: the elimination of the different climatic zones in Canada and the adoption of a single zone, the coldest zone.

This means that a window purchased in the Vancouver or Montreal area must have the same energy performance as a window purchased for the Winnipeg or Yukon area to be classified as Energy Star, even if the temperatures are not the same. By raising the standards for us who live in southern Canada, our doors and windows will be warmer, thus saving energy and money in the long term.

To be ENERGY STAR® certified, residential window and door models must meet or exceed an RE factor of 34.

To make the best energy-efficient choice, rely on the RE index. The higher it is, the better the door or window performs. The energy efficiency index makes it possible to compare all types of fenestration products, regardless of their materials and characteristics. For the U factor, the smaller it is, the better the window is insulated.

Make sure that the energy characteristics appear on your submission: transparency and access to this information are important for an informed choice.

All of our products are ENERGY STAR® certified. Find out more, ask for ENERGY STAR 2020 certification.
