My friend the pro responded to my question about what product they used and could it be poured.
"Foam we used was only for spraying, reaction time was to fast for pouring. It is a closed cell. We had several manf. BASF was one of them, as for the iso or the A side there are only two plants in the counrty that make it. We used different density depending on the application, in freezers or cold storage we would use a 2# density, for house or metal buildings we would use a 1.5# density, and on roofs we would use a 3# density
