Can anyone tell me what cavity wall insulation looks like when injected into
the wall please.

Is it like a sort of loft insulation but is little tiny bits.... I can't
think of anyway of describing it, sorry !

varies, mine is the injected liquid foam type, you can see it in places
in the loft where there were gaps in the bickwork and it "flooded in" a
bit, dripped down the wall and then set, when modifying the porch I
found another place where a load of it had found its way through a hole
chased for mains cables to the garage.

some I think are like the contents of bean-bags, blow into the cavity.

What you have is glass fibre granules. Probably the best type for an
existing house. Lots of different forms of insulation have been tried.
The foam method was used a lot at one time. It is easy to put in but, as
I found out in a past house, unreacted chemicals can cause a bad and
potentially hazardous vapour. It took a few weeks to clear completely.
Its a surprise when you come across some of extruding from the edges of
the wall for example in the loft. New houses usually have slabs of
insulation put in as the walls are being built.

Its not at all dangerous, perhaps unless you eat it.

I've recently had rockwall insulation installed. It is white, fluffy and in
small pieces.

Note that I had my cavity wall insulation done from the inside.

One type is like a soft expanded foam - a bit like dried shaving foam.

Another is polystyrene beads - like in a bean-bag

The third type is fine tufts of fibreglass - if there is a "Bear
Factory" near you, go and see how they fill the teddybears, its more
or less the same.
