[Greenbuilding] foam in a can (cabinet)

[Reuben Deumling]

You have a good memory, Bill. It was a Sanyo, and they still make a variety
of models without Auto Defrost that lend themselves to this modification. I
know less about where extra components are put in Auto Defrost fridges and
so am wary. You are correct that as soon as you get coils or heaters or
other thermal components hidden inside the walls such modifications are ill
advised.
The particular fridge I am hoping to tackle next is quite small, very old
(pre-fiberglass, pre-Freon) and the steel is so thick that I am not
particularly concerned about bowing it. Thinking more about this project I
started to wonder if some company might not make a pourable foam (as opposed
to it coming out of a pre-charged can). My goal is to get it up to 40" into
a cavity and I suppose there's a limit to what can be achieved with a long
straw.
Thanks.
