I suspect this is a long shot in HK but thought I would ask.
With the temperatures getting down we get some nasty drafts. When it is windy our curtains actually move (yes, on the inside of the window!).
Anyone know a source for window film? I am looking for something like the 3M Window Insulator. Used it in the past in places with bad windows and the difference is amazing!
I don't care if it is 3M or some other brand, anyone know a source for this type of thing around HK?
