Hi all again.
Looking at a fridge for a boat and was thinking the poly version of evercool would be tougher.
I realise they are a tad heavier and less efficient. But mate said go fibreglass due to the expansion of poly with heat?
I do know my poly esky lid fits very well when not in use but when it is full of ice and inside is cold and the lid is in the sun say 30C + the top of lid must expand while the cool inner side does not leading to the lid to bow and not seal so well.
The lid returns to normal shape when the inner + outer lid temps become more simialar.
Not such a big deal realy but dont want a fridge doing this and gobbling up battery power.
Any thoughts or experince?
Regards GN

Thanks Garry
i think that perhaps the temp of the esky lid maybe getting much hotter that the day temp due to being in direct sun????
So perhaps the material / quality of the evacool poly box is better or the actual temp of the outer lid skin inside the vehical is making the difference.

I got the yellow one because I can stand on it and its cheaper. I dont care what its going to look like either after some rough handling. The fibreglass ones take advantage of the insulative property of fibreglass and they dont need as much insulation. Thinner walls, look better and more expensive. I would consider getting a bag made up if you want the thing to stay pretty.

owen
