Thanks for all suggestions.
Just curious if the expanding foam gas same insulating properties per
volume
as pipe insulatoin?

Products typically have a rating in watts per hour of energy transmission.
But PU foam-in-a-tin can not because it depends how it is used. The user
affects how aereated the foam is. However it will be roughly comparable
to
any PU foam product such as kingspan, look on there web site. Err on the
lower side since their facilities obviously allow the best possible values
to be achieved.
