Review: Cuts Drafts from Small A/C - This is a great cover for a small air conditioner. Packing it underneath with foam and weatherstrip tape, it already has an aluminum lining that probably helps with cutting down any draft. Has velcro, so while it is not a custom fit, it fits neatly around the a/c and keeps the room warmer. Takes some work, but worth it!
Review: Works great - Easy to install and cuts down on the draft well
