Thanks, The insulation is 3 different types depending on what would fit in where. Perhaps if I built another coffin I would make it bigger inside to fit the thickest insulation on all sides but hopefully that will be a long way down the track as this one has been a lot of work. Some of it is the foil backed rubber type insulation from clark rubber, left over from what I use to lag my urn. The other is insulation board from Bunnings, I used some of both thicknesses available which I think is 30mm and 50mm. I also wonder about losing coldness through the coffin. If i'm not going to be using it for a few days I turn off the STC which controls the coffin fan, figure there's no point in pumping cold air up there for nothing. I also figure the thing in the coffin which is most conductive to cool and therefore best at losing it to the outside is the shanks and taps, there's not much you can do to prevent cold loss through them.jer88 said:Well done, that looks bloody awesome. I'very just got into kegging and have made one out of a older tucker box chest freezer. I was just wonder what you used to insulate your coffin. My freezer is set to 3 degrees and cycles about ever 1,1/2 to 2 hours, I'm not sure if this is normal but I think coffin needs better insulation
