Just got a new window AC. It's meant for vertical sliding

Also, I can't drill or use silicone glue or such (renting), so I was thinking of using pic related to fix the whatever panel I wind up using.

I use this rigid foam stuff when I need to poke pipes through a ground-level window.
The downside is that it has no strength at all and offers no resistance to break-ins.

You literally posted a picture of what you need to do....

Super strong adhesive on a rubber backing ... and you think that will be easier to remove cleanly than silicone?

I figured strong rubberized tape would pull off in one piece with a slow persistent force.

With silicone, I'd have to scrap it off with a tool, no?

Also, wouldn't the thick rubber contribute to the sound-insulation?

If not, I might use like pic related instead.

What do you think?

Do you think wood would work for both sound insulation and water resistance?

I figure I'd have to oil it, and even then in my experience I've generally found wood to be high-maintenance.

It's more expensive than plexiglass too. But really, I'm shit with wood.

What are your thoughts?

Wood won't give you much insulation, and due to its weight you might have a hard time getting it to stay in place with tape.
use

and paint it if you don't like hot pink.

This is foam, right? I imagine it's gonna be great for thermal, but what about sound? I live 2 blocks away from a railway and even though I'm on the 17th floor the noise is still pretty bad if there's nothing damping it.

Upside though is that I don't have to worry about strength for break ins. As long as it will hold against wind or rain that high up.

Also, did they actually pay to use the Pink Panther license for this foam stuff? Wow.

Do what OP's pic. Paint the outside face white then a few coats of poly. Cut some of that pink foam to size and glue to the inside of the plywood. Boom! Strong and insulated. Maintenance is reapplying poly every year or two.

You keep worrying about sound reduction.
If you don't install the a/c unit, how much does the glass reduce the sound?
Anything you put up there will do as well as the glass window for sound isolation.

You're also worried about high maintenance of what you put up.
You're renting. You won't be there long enough to have to maintain it.

Use plywood like in the OP image.
Safer, better strength, more durable.
Paint the outside to match/compliment the house.
Paint the inside to match/compliment the room.

My aunt has been in her apartment for about 40 years now. While I wouldn't recommend copying that at all, you never really know how long a renter is going to stay.
