There is a room that has a window, the frame of the window is made of aluminum. This window is subjected to direct sunlight a long time of the day, which makes the aluminum get really hot, and start acting as a heat radiator and heating up the room pretty quickly.
What can I do to block the sun from heating up the window frame?
I tried putting some paper with adhesive tape, but it was not durable at all, even though there wasn't a lot of rain or water.
I prefer something DIY, if possible.
