I'm only trying to keep fish fillets cold for up to 36 hours. I don't need to keep any other foods cold. There really ain't many good options for refrigeration while living out of a van unless one has enough solar to power a fridge.
I spent four months in New Zealand in 2009 and camped in my tent virtually the whole time. That was the first time I heard the term "chilly bin". I purchased a cheap self inflating air mattress that was totally useless. I quickly upgraded to a much better one and used the old one to wrap around my "chilly bin" for added insulation. It worked quite well for that.
This is a link to a Bob Wells video about my ice chest from the 2016 RTR.  It is a large plastic bin and a small plastic bin with insulation between.  I skimped on the top insulation making the bottom and sides thick.  The sleeping bag tossed over the top works but a few more layers of foam insulation would work too.

Yeah I've tried air mattresses and these are good for nothing, and I can't even imagine using one of these for chilly bin insulation.

Thanks for the video Trebor (and Bob). It provides some good ideas that I can include in my D.I.Y chilly bin build.
Good luck.

Cancel using extruded polystyrene (XPS). According to the product site, it only has an R value of 1.1 at 30mm thick, which is the thickness of the boards. Basically it has almost no R value.

Can't even call extruded polystyrene true insulation with that R value.
I think your product is not true insulating XPS, rather a building board made with a denser XPS

The info I have is XPS has an R value of 4.7 per inch

A building board made with denser XPS?? I thought there is only one type of XPS.

I used this stuff to insulate my van floor thinking it was real XPS. I wasted time and money but I won't be making the same mistake with a chilly bin. After all the confusing about insulation and it's R value, I've decided to just buy the best chilly bin I can find and save myself some stress. I'm still not convinced about the quality of chilly bins on the market but I feel I have no choice but to buy one at this point.
