In short
Window installation is structural work: panel ribs, sealing, and possible homologación must be respected. We do it in the workshop with templates and road-proven products.
Before you start
- Choose windows certified for vehicle use.
- Set position based on bed and interior circulation.
- Assume a reform project may be required.
- Do not buy before confirming panel thickness and curvature.
Choosing the window
We prioritise brands with camper track record and support in Spain. Fixed vs opening depends on ventilation and security. We measure outer and inner opening with planned insulation. An oversized side panel window can flex sheet over time. Alexis recommends sizes per model—Jumper, Transporter, Sprinter are not interchangeable. We are not a window shop without installation.
Cutting and preparation
We mark from template, protect paint, and cut with tooling that avoids burrs cutting the gasket. Perimeter reinforcement follows manufacturer data. Exposed steel is primed before sealing. This is not garage DIY—a millimetre error shows in rain. Technical review stays pending until internal sign-off per project.
Sealing and interior integration
External butyl, compatible Sikaflex, stainless fixings in the correct sequence. Inside we leave reveal for panelling and blinds. We check frame drainage so water does not enter insulation. Bed-side windows get blackout and sometimes integrated mesh. We hose-test before closing trim. Leaks top forum complaints; in the workshop we prevent them with process.
Homologación
A new side opening may be a reform depending on papers. We guide when to file before long-term road use. Our homologación section explains the concept without invented prices. Paperwork and ITV tie to your specific van. We install with inspection in mind, not just Instagram photos.
Common mistakes
- Cutting the hole before planning insulation and panel thickness.
- Using generic silicone instead of the manufacturer system.
- Low window without frame drainage.

FAQ
How many windows do you recommend?
Depends on layout and airflow. Few well sealed beats many poorly fitted.
Can I supply windows?
If vehicle-rated and dimensions validated, sometimes yes with workshop fitting.
