Hi, we are in a rented studio flat, so nothing that could mark the glass or damage it can be done.
We have large sliding patio doors, which from sunrise to sundown heat up and make the room boiling hot. We have blinds but there is gaps, letting sun in even more, installing curtains as it is a rental is not an option.

We have bought an AC unit, but unless its running, we are uncomfortably hot- and we cannot afford to run this all day if we are in the flat.
If you can think of any ways to block the sun from coming in please let me know!!
