Celia,
I don't think Peccavi quite understood what you wanted...
You used to be able to get hold of a door curtain rail that lifted as the door was opened, usualy made from brass, which was fixed directly to the door.
As I say these are, were, "old fashoned", and a cheaper way of doing that sort of job nowadays is to use draught excluders, which you can get from any D.I.Y. store...
Here's another tip...Talk to the "old guy" at the store, he'll be a good bet to get info on how to do jobs around the house.
Hope I've been of some assistance
