    I need mineral wool about 20mm thick to fill a gap in a wall. The thinnest I can find in 25mm.

    Is there an alternative I can use, or will the 25mm squash in (it is mainly just to prevent an echo passing through the space).

    A bit of density will improve the sound absorbing capabilities. If it's standard loft stuff could go quite a bit thicker nominal thickness.
