24 Pack Black 1" x 12" x 12" Acoustic Wedge Studio Foam Sound Absorption Wall Panels (24pack-black)

I move around a lot. Is there any ideas out there what I can do to put them on the wall and take them out whenever?

Does it come with a sticky side to put on the wall?

Do these provide any thermal insulation too?

Are these waterproof? Could I use outdoor?
