Why do you need window insulation filler?
Although these 3 windows of Revel come with blinds, the blinds do not have insulating properties. Therefore, for the overall thermal insulation of the camper van, these three places are weak points, so we need to add thermal insulation layers between the windows and the blinds.
How to use?
Put 3 wool insulation pillows into the gap between the corresponding window and the blinds, then pull up the blinds.
Equipping both the cab glass and the rear door glass with insulating shades will give your van the best thermal insulation performance. Check out our related recommended covers.
