Argon-filled windows use a dense, inert gas between the panes to slow heat transfer, making your home more energy-efficient. Unlike plain air, argon reduces convection and cuts down on drafts near the glass, especially in cold weather. It's a subtle upgrade that keeps rooms quieter and more comfortable year-round.
