A PVC awning window is a type of window made from polyvinyl chloride (PVC) that features a top-hinged design, allowing it to open outward from the bottom. This design is ideal for providing ventilation while protecting against rain, as the overhanging structure helps keep water out even when the window is open. PVC is known for its durability, low maintenance requirements, and energy efficiency, making PVC awning windows a popular choice in modern construction. They are often used in residential and commercial buildings, offering a sleek appearance and enhancing natural light.
