How can I stop a draft coming through my french windows?
This is a difficult task as doors should be constructed for draft exclusion. A photo would have helped. There are a number of professional solution to this problem and the doors may need joinery work done on them, by routing a seal into one of the doors. Professional window and door seal come in all shapes and sizes.I think in your case a double lipped synthetic rubber seal routed in to the one door would reduce the draft by some 90%. If you can use a router or know of some one that can, then mail me a photo and I will send you a a seal that will do the job.
