To cut the Celotex floor insulation into joist gap panels, I

some of these jigsaw blades which should be good for up to 100mm.
Once you put any sideways force on a jigsaw blade it will bend and you
won't get a square cut any more.

Cut by hand using a panel saw?

Or score and snap. Works at 25 mm not tried 75 mm that might be to
thick or require to much force over a too long a distance.

I used an old bread knife - works well.
+1 - I've just cut up a load of 50mm celotex for some between joists flooring,
takes seconds to do an accurate cut. I've found the best way is not to cut all
the way through - do it to about 90% then 'snap' the board and break the uncut
foil with the knife. Bit like cutting plasterboard.
