As winter approaches, I am thinking of the best way to insulate my Weber kettle. I have looked in the archives and not found any actual insulation methods. I have been advised on another forum to maybe try a cardboard wardrobe that people use when moving home, which may work and maybe put a welders blanket or something similar on the inside as a liner. Does anyone else have any suggestions for my Weber kettle? Thanks. PS i am in the U.K.
