Sometimes, I stay up long, and when it gets dark, I usually turn on the lights and close the roller shutters in the room where I am, so that my neighbours won't see what I'm doing (programming).
Currently, it is summer and quite warm in the region where I live. This is why, during the nights, I want to open the windows and of course the roller shutters to let cool air come in.
Now there is an issue: When I finally go to bed, I want to open windows and roller shutters in the room where I was, but opening them makes a lot of noise - and I'd like to avoid this in the middle of the night.
What can I do to be able to open the roller shutters more silently?
The roller shutters look very similar to those in the picture of the Wikipedia article. They obviously are made from some kind of plastic:
It helps a lot to open them slowly, but it still is a lot of noise. I tried to oil them, but this did not change anything.
