Looking at using the mix type of insulation. Just wondering if this makes its a permanant install, does it harden like cement?

One advantage is that you won't get bits of perlite/verm constantly sifting down through any gaps in the block-off plate. Not an issue if block plate is airtight. And also some branded pour-in mixes are tested & UL listed for use with certain liners. Not sure if that's true for generic perlite/verm?
I only have experience with "Thermix" brand. It does not set-up anywhere near as hard as concrete, but will support it's own weight & will hold the flex liner in there tight. Would be a pain to remove, but not impossible. If you have clay tiles that are miss-aligned I could see that making total removal of the mix very difficult without damaging the tiles.
