Window screen frames are typically made of aluminum or vinyl. Aluminum frames are lightweight, durable, and resistant to rust. Vinyl frames are also durable and lightweight, and they are available in a variety of colors.

Fixed window screen frames are permanently attached to the window frame. Retractable window screen frames can be rolled up or down to open or close the screen.

Window screen frames help to keep insects, pests, and debris out of your home. They also provide ventilation and can help to improve air quality. Some window screen frames are designed to block out sunlight and heat, while others are made to allow natural light and air to flow through.

When choosing a window screen frame, you should consider the size of your window, the type of material you want the frame to be made of, and the features you want the frame to have. You should also consider the style of your home and the climate you live in.
