Argon Fill Windows for Maryland’s Climate: Benefits and Tradeoffs

Why Argon-Filled Glass Is Common In Maryland Homes

Argon fill is easy to miss on a spec sheet, but it can make a real difference once a house starts feeling less comfortable near the glass. It helps slow heat transfer through the insulated glass unit.

That sealed cavity is where the argon sits, and it works because argon is denser than ordinary air. That matters here because a mediocre window tends to show its flaws fast once the weather turns humid, cold, or windy.

How To Decide If Argon Is Worth It For Your House
