Read the ENERGY STAR label
The label, which is on the product itself or on the sales literature, indicates which of Canada's four climate zones the product is qualified for. The higher the number of
zones, the better its energy performance and the greater your energy savings.

Choose windows or patio doors rated for your climate zone.
