You have the Schwintek In-Wall slide system. There is a perimeter bulb seal that is on the inside of the exterior slide surround than seals the slide when closed. It works well when properly installed. When open, the slide is sealed by a thin wiper seals. These seal are found on the exterior of the coach's vertical walls and on the top and bottom inside edges of the slide. They do not seal well even if in good condition and have cutouts for the slide tracks and fittings. Dust and water will seep-in during windy conditions. In cold conditions the coach is much easier to heat with the slides closed. I never leave the slides open in thunderstorms as I have already lost one slide topper due to high winds.
