For homes heated by electricity, the utility estimated that customers can save up to 10% on their heating bill with Energy Star qualified windows and patio doors, adding that these energy efficient models are 20% to 40% more efficient than conventional ones.
Look for the Energy Star symbol on the product itself or in the manufacturer’s documentation to make sure that a window or patio door meets Energy Star requirements.
Consumers should verify that the product in question is qualified for the climate zone where they live, cautioned Hydro-Quebec.
It is also recommended that the windows and patio doors be installed by professionals since the quality of the installation has a direct impact on the product’s performance, said Hydro-Quebec. “An experienced installer will be able to minimize heat loss and air infiltration around the frames,” it said.
