Thanks for the reply; not to be critical but I don't know how to seal the
gap where the the lower and upper sashs' are offset.

One thing you coluld try would be to get some of the foam rubber type
stuff that is made to insulate the water pipes. Stuff it in the crack
and cut to the length you need.
