Should I add windows to my van?

Think about - Size & Fit - Ensure the windows fit the specific contours of your van. Ventilation - Think about how much airflow you need. Fixed window offers none or Slider which generally has a half panel size opening. Privacy & Security - Tint may be a benefit, while a fixed window is more secure than a slider. Cleaning - once a month, clean van windows with a mild window cleaner (out of direct sunlight), and buff to a shine with a soft cloth. Maintenance - check the seal and the surface regularly for any issues and address as soon as possible, to keep your windows in great condition.
