Description
Universal Van Bunk Window – VWD VW3310R Half Slider (OD 34” x 11”)
The 10” x 33” half-slider bunk window has become a standard size across the van conversion industry. Many manufacturers produce variations of this format because it fits well between structural ribs and works in a wide range of layouts.
The difference is not the size. The difference is execution.
The VWD VW3310R is built as a reference-grade version of this window — consistent fitment, stable latch operation, and long-term seal reliability backed by a company dedicated exclusively to van windows.
Universal Fitment
- Works with most camper van layouts
- Commonly installed in bunk and bed areas
- Fits between structural ribs in many vans
- Suitable for custom and DIY builds
This size became popular because it provides airflow without sacrificing wall strength or cabinet space.
Balanced Ventilation For Sleeping Areas
Bunk windows serve a different role than large side windows. Their purpose is localized airflow where occupants rest.
- Allows night ventilation without opening doors
- Improves comfort near pillows and bedding
- Works with roof fans for steady airflow
- Reduces humidity buildup while sleeping
Small controlled airflow near sleeping areas prevents condensation more effectively than large windows positioned far away.
Half Slider Control
- Adjustable opening size
- Integrated insect screen
- Secure latch position
- Ventilation in any weather condition
A half slider allows airflow regulation instead of full exposure to outside air.
Privacy Glass
- Automotive solar tint
- Maintains interior privacy
- Reduces glare
- Factory-style exterior appearance
Clamp Ring Installation
- No exterior body shaping required
- Interior mounting ring compresses seal
- Suitable for DIY installation
- Serviceable and removable
Clamp ring windows are often chosen for custom layouts because installation does not rely on permanent bonding.
Why This Version Matters
Because this size is widely used, many variations exist. Reliability comes from manufacturing consistency — frame tolerances, seal compression, and latch durability.
Van Windows Direct focuses exclusively on van windows. The VW3310R reflects standardized fitment developed across thousands of installations rather than adapted automotive glass.
The goal is predictable results: a window that installs correctly, seals correctly, and operates consistently over time.

FAQ
Why is this size so common?
It fits structural spacing in many vans while providing meaningful airflow without major body modification. Also used in most fiberglass extensions, bump-outs, flares and capsules.
Is a bunk window enough ventilation?
When paired with a roof fan or larger intake window, it provides effective localized airflow while sleeping.
Can this be installed by a DIY builder?
Yes. The clamp ring mounting system is designed for accessible installation.
Does small airflow really help condensation?
Yes. Continuous air exchange near occupants removes moisture before it condenses on interior panels.
