Where can I get fine plastic mesh netting to make a screen for
keeping out insects?

I want to put some across one or two of my windows so I can get air
flow but not permit insects in.

I have tried various odd meshes and even some mesh net curtains but
they do not seem as good as the mesh I have seen used in windows when
I have been on holiday abroad.

Do the DIY chains like B&Q or Focus have something suitable?

That's where I got some a couple of years ago (B&Q) where they had it by
the metre in the garden section (outdoors), available in white (yellow) or
grey.
