ENERGY STAR®-approvedwindows reduce energy costs, keep your home comfortable, reduce outside noise, and can also reduce condensation in cold weather. According to Natural Resources Canada, ENERGY STAR® qualified products will reduce your energy costs by up to 12 per cent.
Using energy efficient products also helps the environment. According to Natural Resources Canada, if you replaced all the original windows and doors in an average older home with ENERGY STAR® qualified products, your household energy consumption would drop by about 7 per cent, saving three quarters of a tonne of greenhouse gas (GHG) emissions annually. If you installed ENERGY STAR® qualified windows, doors and skylights in an average new home instead of conventional products, your energy consumption would drop by about 12 per cent.
