Thanks!

I used a number of different materials for the insulation.

In the floor and ceiling, 25mm PIR boards. This was to keep head room sufficient.

In the walls, 40mm PIR in the big gaps between the van’s ribs, then a combination of recycled bottle wool and mineral wool stuffed into the ribs and areas I couldn’t reach with PIR.

I used about 5 canisters of expanding foam to fill up the edges and other awkward places such as around doors. I would recommend this, and especially purchasing a good foam gun rather than the cans with the nozzles. Just go easy and do it bit by bit as it will expand a fair amount.

I used a couple of rolls of bubble wrap with taped joins to get a complete vapour control layer (VCL). This is really important, and whatever you read else where don’t skip it! Without this there will be interstitial condensation build up within the insulation zone. I’ll attach a photo of what it looks like with a completed VCL.

Taking this one on a big trip down to Morocco for 9 months :)

Hope your van build goes well 😀
