What Are 4 Track Windows?
4 track windows are vertical sliding window panels made of durable vinyl that can open up to 75% of the window space. Unlike traditional glass windows, these panels are lightweight, flexible, and built to handle the ups and downs of seasonal weather. You can raise or lower them easily to control airflow, visibility, and protection.
They’re often used in screened-in porches or sunrooms to convert the space into a more usable, enclosed area—without the cost or complexity of full thermal glass.
