I've been using a 7cuft chest freezer with temperature controller as a fermentation chamber and beer/wine store (when not fermenting). I've just bought a kegging setup so will be building a collar soon. Living on a hot island, insulation isn't something I can lay my hands on easily. Do you need to insulate the collar and if so, has anyone got any novel insulation ideas that don't incvolve popping down to Lowes/Home Depot and picking up a big sheet of insulation (not an option).
I'm thinking about a 6-8inch high collar (might be able to get away with 4inch if it will make the difference regarding insulation). I plan on using 1 inch thick wood but could use double (or triple) thickness if it is worth it. I had wondered whether laying sheets of kitchen foil between 2 peices of wood would affect the insualtion qualities enough to make it worthwhile.
