Insulation for a DIY air cooling pot
Skadeetin
| Posted in Green Products and Materials on
we are building an air cooling pot from a food grade 1gal plastic bucket and need to LINE THE BUCKET with an insulator. Syrafoam is used in most cases but we would like to avoid it if there is something else available. It should be water poof as ice will melt inside the bucket. Need to be able to cut to fit easily and be very lightweight. oh–and cheap! because we’re cheap. 🙂
Thank you very kindly!

Skadeetin,
What's an "air cooling pot"? My first guess is that it is used to cool food down, using ambient air to cool the food -- but if that were true, you certainly wouldn't want any insulation.
Maybe it's something like an ice bucket -- designed to hold a bottle of white wine and ice?

Are you trying to make a "pot-in-pot refrigerator" for keeping food cool or an evaporative cooler for keeping a room or building cool?
All the waterproof insulation I can think of are foams. But you're already using a plastic bucket. What makes your plastic bucket ok but your plastic foam not ok? This might help someone come up with a type of insulator that would be acceptable to you.
Edit: as a side note, the spam filter blocked my post when I tried to link to the wikipedia pages for pot-in-pot refrigerator and evaporative cooler. Is it possible to whitelist wikipedia in the spam filter so folks can post wikipedia links?
I'd line the bucket with another bucket - then you can put whatever you want in the gap between them. Pour-able foam, perlite, etc.
