The PO of our AS replaced all the curtains with metal blinds. They do a nice job of blocking out the light. I think the one in the galley is original and he just matched them on the other windows.
On the ceiling vent it looks like a PO fashioned a cushion using the reflectix stuff on top and terry cloth on the bottom. It's about 2" thick and does a nice job of insulating. Friction holds it in place and there's a slight cut for the handle to fit in for a good fit.
