I was wondering if anyone here has any experience with using metal skinned PU freezer panels for residential use. I prefer the industrial look of them and they are plentiful and cheaper used than any other type of sip I have found. The cam lock system seems very easy for installation as well. I know these are usually used inside of a larger structure but with proper weatherproofing on the roof and structural support for snow load I believe they could be used. Thanks in advance

Most of the metal skinned freezer type panels that I know about are not structural.  That is ok, provided there is a structure to hang the SIPS on.

The panels I have seen that have the cam locks either have a wooden frame on the exterior or they have a hard foam frame. These are manufactured by Kysor panel systems and are used in Wal-mart and Sams Clubs and are sold second hand via eBay for around $200 for a 40in wide by 10 ft long 4-5" thick panel.

$6 per square foot doesn't look like a good deal for a panel with questionable structural properties (and probably none of the produce approvals needed for you to get your permit). You'll pay even more when you account for the loss in piecing together second hand panels.

It is a bad idea

some freezer panels are not structural / or are very limited,
some years back I replaced 24 ft. freezer panels on roof "clear span was 20ft"
Manufacturer out of Orlando (out of business) and Buider/Engineer (deceased) ,
MFG. span charts were 10ft. , needless to say they failed and the owner left holding the bag.
If you think that is a road you want to take , then God Bless you

Kysor claims indoor clear ceiling spans of 20ft for 5" wood framed panels. Obviously that would change outdoors. I guess what I am unsure of is how these panels with wooden frames are any weaker than any other metal SIP. I am sure they are at least as energy effiicient. They have rubber gaskets between each panel. They even sell complete industrial structures with windows.

So even for the sake of argument,
you dont't know what kind of condition they are in until you get them, they could have been delaminated in the demolition process
You are limiting your designs based on 10 ft. or what ever lengths are available

you will need to pay for shipping.
you will not find an engineer to certify them.
not even for a shed would I not waste the time , effort and agrivation
