what type of insulation do you use around pex when going between stories? normally i would use spray foam around the copper and romex, but I am not sure if that will hurt the pex.

Why would you use spray foam? You ever think what a pain it will be to make any repairs in the future. If the pipe chase is in the middle of the house I would not bother to put anything on it. I would only put pipe wrap on any pipes. I think it is alot simpler to use and looks alot nicer.

Spray foam is rated as a fire stop/block material?

I've gotten the spray stuff onto vinyl replacement windows, and it definately compromises the finish. The windows should be tougher, since they need to stand up to UV.

I cover about 1’ of the pipe in duck tape then I use spray foam. I have used Rook Wool but the inspectors don’t like it where I’m at.

I was thinking about tape, but I also worry about that compromising the PEX. PEX sure is delicate...
How about foam pipe wrap and then spray foam around that?

I would do that that. If I had to do what you are talking about I would do that.
