        "text": "The lifespan of energy-efficient windows typically ranges from 15 to 30 years, depending on the material, installation quality, and maintenance. Vinyl windows generally last 20-40 years, while fiberglass can exceed 30 years. Wood windows can last even longer with proper care. The longevity of the insulated glass unit (IGU) and its seal is crucial; a failed seal can lead to condensation between panes and reduced efficiency. Regular cleaning and checking seals can help extend their effective life.",
