PVC windows are made from polyvinyl chloride, a durable and weather-resistant plastic. They are popular for their energy efficiency, as they help keep homes warm in winter and cool in summer. PVC windows are also low maintenance, requiring only occasional cleaning to maintain their appearance. These windows come in various styles and colors, allowing homeowners to choose designs that match their preferences. Additionally, PVC windows are resistant to rot, rust, and fading, making them a long-lasting option for residential and commercial buildings. Their affordability and performance make them a common choice in modern construction.
