Windows and doors are the #2 cause of air leaks in the home, after the floors, walls and ceilings, according to Money magazine. If you find that weatherstripping your doors and windows isn't doing the air-sealing trick, it might be time to replace them for more energy-efficient models. Look for ENERGY STAR® windows and doors for the highest energy efficiency. ENERGY STAR® windows and doors save you up to $450 a year, depending on the climate. And there are many benefits—less maintenance, noise-cancellation and better insulation, to name just a few. Also, over time, your investment in energy-efficient windows will pay for itself.
