This type of sash fastener, if properly positioned, should pull them
together.

I find brighton fasteners to be much better. Especially where windows
don't necessarily line up exactly. e.g.

It would also help if the solution was such

that it stops the two parts banging into each other when it is windy
outside.


If you mean when they're open, a piece of folded cardboard. Very hi tech
I know, but the only thing that works


I was wondering whether insulating strips could be attached - but am
worried that they will be very difficult to fit and will stop the
windows sliding properly.



I think mighton do some stuff for sah windows. Although once I'd striped
several of mine, repainted & new parting & staff beads etc and they
hardly leak at all. In fact probably less than the 4000mm^2 you require
per room for building regs.

There was one place I found ages ago that sold kits. But they were
pretty expensive for a few metres of staff bead with brushes fitted.
(About 100 quid a window when I last looked).
