I have a letterbox in the middle of our door which I want to block up. The aim is to remove the terrible draughts coming through the door. In addition, we want deliveries to be made at a different part of our house, so I have installed a wall mounted post box there.
Does anyone have any suggestions on the best way to blank off the letterbox? Once I have removed the box it should just be a big hole in the door. I intend to fill that with polystyrene or rigid insulation, probably seal that in with expanding foam to avoid moist air getting to the external face.
I was wondering about using a plain fingerplate turned horizontal but would that survive the weather?
The door is painted hardwood.
