Well, I stuck a temperature probe in my old chest freezer and discovered
that its not really performing to spec. Its a 3/4 star rated freezer (I
think he 4* rating only applies when the fast freeze mode is switched on)
and the temperature seems to cycle between -15.5 and -12 C.

When I turned it off for the hours the temperature rose to -4 C which is
clearly not good for longer term food storage. Fortunately its very much a
€œspare€� freezer thats only been pushed into service to allow us to
stockpile a few essentials should we have to self isolate.

Anyhow, I dont think that the insulation has obviously failed (the case
isnt bulging anywhere) but I was wondering if I could just glue some
kingspan/celotex etc to the outside? If I were to do this, should I glue
the foil side to the cabinet or have the foil to the outside?
