Maybe not quite DIY but still ...

My seat-of-the-pants measurements and observations tell me that the
cavity insulation in our house could be a lot better.

The cavities are filled with small pea-sized polystyrene beads. I am
far from convinced that the cavities are 'fully' filled - I guess they
are originally filled from the top, so I'd take a safe bet that there
are big voids under windows, fo example. And likely the beads settle -
so there may be a void at the top of the cavities. I also am less than
convinced of the efficiency of this type of insulation.

Has anyone got specific experience and/or comments on it ?

And a bigger question - what could I replace it with - assuming I'm
willing to pay a large amount for a substantial improvement in
insulation ? I think, however, that removing and re-building the outer
leaf is not on the agenda, but if anyone has that experience please say so.
