I have used some of that aluminum-backed, bubble-wrap insulation as a floating cover on my mashes for over a decade. I originally employed it as an insulator to help retain heat, but it also serves to isolate from atmospheric contact. Was I ahead of my time??
I've used that as a lid for my mash tun, but over time I've noticed the moisture deforms the product. How does your floating cover look after a decade?
