A PVC slat for a jalousie window is a horizontal panel made from durable, weather-resistant polyvinyl chloride (PVC). These slats tilt open or closed to control airflow, light, and privacy. PVC slats are lightweight, easy to maintain, and resistant to moisture, making them an ideal choice for areas with high humidity or exposure to the elements. They offer a clean, modern look, are highly durable, and help regulate temperature and ventilation in a room.
