Van insulation for your van conversion is one of the most debated subjects. There are so many different ideas about how to insulate a van for a comfortable life in the van. Vapour barrier – rigid or batt – Such as natural Havelock Wool, or spray foam or thinsulate Insulation. Some folks use more traditional brands like rock wool and pink fiberglass. Each will have positives and negatives to consider. All vans will have moisture. It’s imperative that you design a system to deal with the moisture in your van. Some insulations are better suited to be exposed to moisture. First is to determine where your dew point is. That is the place the moisture will be. Special care around penetrations is needed. If you're installing Maxair Fan or a Fantastic fan you need to be careful. If you plan to have a air conditioner on the roof such as a Dometic 640315 CXX or a Coleman Mach 15 you'll need to take special care. Also determining when to insulate is a factor. I would recommend you wait until the design and construction of your DIY cabinets is complete, or just before if you're installing with a back. For the best conversion and vanlife you should insulate just before you cover.
