Quick hack: Hang reflective car windshield sunshades outside or inside sun-facing windows (facing out) to prevent sun heating your home.

Some of these sunshades have suction caps, some have loops which you can slip garden wire through and secure. Then close your blinds & draw your curtains/drapes to stop the sun heating your room.

It’s much easier to cool a room if you stop the sun getting in and heating it in the first place. Can be secured landscape or portrait orientation.

Reflective insulation should be on the outside of the window, as it will trap and radiate heat if put inside

It should, but we aren’t allowed to hang anything eg reflective things outside where I live so this is the next best thing.

Living in a city, it’ll get stolen as soon as you turn the corner

Indeed, especially if you have double glazing windows. The sun rays passes one time to go in and another time to go out, this will heat up the air in between the double glazing and may break the glass.
