what should I use to insulate the lid of an old chest freezer?

[Kali]

I have a wonderful old freezer that originally had fiberglass insulation inside the lid. that got removed due to lack of care and we have been using the thing with an old piece of styrofoam sitting loose on top for a while. I was finally forced to de-glaciate and clean the thing this weekend and I want to put the lid back together. I was thinking of getting a new piece of insulating foam and gluing it inside, covering with plastic sheeting and then replacing the original hard (but thin) plastic liner.

or should I get fiberglass? need to move fast as I have a half a beef ready to bring home from the packing house.

1. One man's vote - just get some sheet styrofoam from Lowes/HD. cut to size. glue in place. boom. n/t

2. Closed Cell Foam

A good closed cell foam should work just fine. You could probably also use a roll of fiberglass insulation as well. Either way, you just want something that will keep the cold away from contacting the lid, and won't absorb moisture.

3. I would use styro--doesn't fly up in my face, easier to shape

I like your whole design idea. Very thorough, IMO. I f you relly want to save $ get the foil backed foam insulation, then no urgent need to cover with plastic ; the foil is quite efficient.

4. I wouldn't want the danger of fiberglass fibers around food

which might not have been a problem at the factory, where the doors were assembled away from the main units. The truth is that fiberglass isn't as good an insulator as styrofoam or even plain old upholstery foam. I'd use either of those.

IOW, don't use what they used if you've got something better.

(I thought this would be an "I wrapped the top in bubble wrap and it's doing just fine" post)
