Interested to learn more about your decision to use sheets of foam insulation on the interior. I assume you did this in place of plastic liner? How does it last and is it is dangerous for edibles? Do you have more photos of the build process?
Sorry, I didn't even see this comment. The decision to use foam instead of plastic liner was it was mostly simpler to install. But I think the foam will be a better insulation then just a sheet of plastic.
