VWD Overlander Half-Slider Van Bunk Window ( 36-3/4" x 13-1/8" )

VWD Overlander Series Half-Slider Van Bunk Window (OVR3511) is designed to make your van life more comfortable, more breathable, and more enjoyable. This slightly larger-than-standard bunk window gives you more glass, more airflow, and a noticeably more open feel inside your camper van. It is a perfect upgrade for builders who want better views and stronger ventilation without giving up privacy or wall space.

Compared to traditional bunk windows, the OVR3511 offers a wider and taller opening, which means more fresh air while you sleep and a brighter interior during the day. Whether you are camping off-grid, parked at a trailhead, or relaxing at a campsite, this window helps keep your van cooler, fresher, and more livable.

The half-slider design lets you fine-tune airflow instead of opening everything at once. The larger 16" x 9-3/8" vent opening improves cross-ventilation, reduces condensation, and helps move heat out of the bunk or sleeping area. An integrated bug screen keeps insects out so you can leave the window open comfortably.

Solar privacy glass with a 17% UV rating blocks harsh sunlight and heat while maintaining a clean, dark exterior appearance. You get more natural light inside without feeling exposed, making your van feel more open while still protecting your privacy.

Installation is simple and secure using a clamp ring system. No welding required. A 3M foam seal is included to help create a tight, weather-resistant seal on metal van bodies. Built-in drainage channels at the top and bottom of the frame help manage water during rain or washing. Does not fit fiberglass extensions.
