diy thermal
esky
cover
![](eskycover1_small.jpg)
On our recent day trips we have been space
poor in the car, so we have been using the small esky to carry
perishables, instead of the portable fridge. At the end of the
day travelling from an ambient 18 degrees into 35 degrees
celcius, produced a less cool esky. For a while I have been
toying with the idea of filling the esky wall cavity with
expandable foam to help with insulation, but that means drilling
holes for the air to escape as the foam is pumped in. So looked
in the shed to see what I can use to cover the smaller esky.
The broccoli box lids have
been sitting waiting for a tip run with foam boxes used to plant
vegies. I cut the foam to size and then taped the lids into a
crude box, then firmed up by covering with the silver bubble
insulation product I had from another project. I did not trim to
size just wrapped the excess around for added insulation.
I think the thermal
quality will be quite good. I didn't bother with a base layer as
the back of the car has insulated flooring and if sitting on the
ground - well it's insulated too.
