Dear Val,
Sorry to trouble you but a couple of years ago I saw an article in Taglines relating to a chap who works wonders with old French windows and converts them from single to double glazed. I wonder whether you still have his information on file please as I would really like to contact him??
With kind regards and many thanks.
Andrea
The chap is called James Wink and his details are in this link
