polyiso insulation boards
I want to use foil face, 2 inch thick polyiso for wall insulation. What tool cuts it the best?

If you are making a couple of cuts, I like to use one of those snap off style disposable blades that you can extend about 3" when new.

If you are making LOTS of cuts, like cutting them down so the fit between stud/rafter bays, then use a table saw.

I am cutting 2" myself now- no foil, but i am using a circular saw with a paneling blade installed backwards.
