Canada is divided into four climate zones based on annual average temperature.
Zone A is the mildest, and Zone D is the coldest.


Using windows and doors that insulate well and don’t let heat or cold through helps with saving energy. Their energy efficiency helps maintain steady temperatures indoors and keeps energy costs down. Investing in quality energy efficient windows and doors will benefit you in the long run by saving you money on your energy bill while keeping the house’s humidity and temperature in check. In addition to a more comfortable home, energy efficiency helps the environment by reducing harmful emissions.

At GreenSaving, our windows have a maximized energy efficiency because of the types of glass used, weather-stripping, fusion welding,  as well as the low-emission glass coatings. We also use the Super Spacer insulating glass unit. It has the lowest U-Value in the industry while providing optimal thermal performance.

Certification from Energy Star can only be approved after vigorous testing from an independent laboratory. All our products meet Energy Star standards.
