We have two bathrooms in our property, both of which have the same problem: There are extractor fans mounted in the windows, but they have absolutely no shuttering or cowling on the exterior side to prevent incoming draughts. So they basically act as a big hole in the window when not in use (they are activated when the bathroom lights are turned on). As such, during the winter months, they let in blasts of icy cold air.
Is there anything which I can attach to the exterior which would stop the incoming draughts? Note that because the fans are mounted in the window, there are no fixing holes - they are just sitting in the circular duct holes, held in by the rubber sealing ring (which doesn't seem very safe, either).
