The Skymaxx rooflight range from Maxxair is suitable for new and replacement installs for 700mm x 500mm apertures.
The Skymaxx LX is available in 23mm to 42mm which is the most popular depth for panel van conversions. 
Forced and non-forced ventilation is made possible as the Skymaxx rooflight comes with clever interchangeable panels that convert it from a vented to a non-vented unit.
