Thermally optimized outdoor #refrigerator (being used for #homebrew #mead). This is #Reflectix attic #insulation. The left side is not insulated as that is where the heat is being vented on this model. Also, the back not insulated, either... haven't determined if there is tubing back there yet. Right side does not get warm when the compressor is on, so it is insulated. #diy #project
