The way to insulate your van is to create a well-insulated room, thereby covering all the metal, with a vapour barrier between the main room and metal whilst doing your best to ensure that your van is well ventilated.

The combination of insulation, a vapour barrier, and ventilation keeps the moist air inside the van warm until it escapes to the outside.

The insulation fundamentally keeps the van warm whilst the vapour barrier prevents the water vapour getting to the cold metal and condensing.

Glass wool is perfect for bunging in all the large cavities that you get in vans, plus it’s cheap, so this is a good product to start with.
olid insulation boards are becoming more and more popular and there is no question they are great insulators, providing you have the space for them.

The insulation can be secured in place using high temperature spray adhesive – it is recommended that a small airspace is maintained between insulation and the finished panels of the vehicle. This provides the space required to reflect heat back into the vehicle.
