What are some budget-friendly ways to block out sun without curtains?

I'm dealing with a couple of big windows (5' x 3') that face the afternoon sun. I can't use curtains because of various reasons, and I'm looking for affordable alternatives that are easy to set up and remove. The windows are high up, so I need ideas that I can manage safely from a step stool, especially since there's large furniture under them. I've looked at some magnetic blackout curtains, but they would block air flow in the evenings when I want to open the windows. Any suggestions for simple, cost-effective solutions that I can move out of the way easily at night would be appreciated! Thanks!

If the issue with curtains is about not being able to drill into walls, maybe try tension rods? They can hold lightweight fabric if you want to go for a more fabric-based solution without causing any damage.

I recently applied frosted tint to my windows, which really helps diffuse the bright sunlight. It's been working great for me, keeping the heat down while still letting some light in! Definitely a good option if you're looking to go a bit more permanent.

Have you thought about cutting foil-backed insulation panels to your window size? You can tape the edges with some sturdy tape to keep everything secured. They can be stood behind your couch or furniture when not in use, and they're pretty affordable! I think this could work really well for you!

SunnyDay216: Ooo, this sounds promising! If I add adhesive magnets to the insulation panels, that could help keep them upright during the day. Easy to take down at night, too!

Another cheap idea is to use large cardboard panels from old moving boxes. Just cut them to fit your windows. It's lightweight, easy to move, and you can even decorate it if you want!

Ever thought about using inexpensive solar blankets? They're basically mylar emergency blankets, and you can pin them up in front of your windows for sun blocking. You get about 10 of them for $13 on Amazon, which is a steal!
