Hi I know this has been discussed before somewhat. However I still have questions and even the tech reps of some of the companies I called don't know their own products.
My question concerns the use of single
PAC spray foam in a can. I understand these are all polyurethane
closed cell and vary from 70-90%+ closed cell structure depending on brand.
Dulux made Parfix triple expanding foam (higher density) claims its water
proof and good for outdoors. The Company tech told me its open cell as are all expanding foam in a can. Which is incorrect.
But can a single
PAC product compare to the 2 PAC low pressure systems?
I have a lot of voids in the interior
of our sailboat. Plus I would like to re insulate my ice boxes and the simplistic way for me would be to utilize expanding foam (at least in part)
If the spray can stuff works as good as say 2lb double PAC then I would be happy to use it. It will not be subject to constant water
but would be in contact with humidity and also dealing with the few pin y of refrigeration
(I'm only concerned with how the can compared to the 2 part system).
The cans maybe a bit more expensive but I would be able to just go through one section at a time spreading out the cost and allowing me to spread the project
Any insight or first hand experience would be highly valued.
