Whatever you put in, if it is a soft sheet material, you need to

You may need to use flexible rods I guess.
You could put in some poly beads, and just push them in bit by bit.
ensuring they do not clog.
But make sure you are maintaining any required ventilation and vapour
barriers etc.

I agree about the pulling. You used to be able to get lengths of rock-
wool type insulation in red plastic covers - I'm sure you still can
(B&Q?) - which would obviate the problem of disintegration.
