David, yes the solar blanket material looks like bubble-wrap (see my previous pics) but is way heavier (20x?) and is UV resistant. I have only had my material covering my two GH's since November, so time will tell whether I leave it as-is year-round. If I understand Karen correctly, she leaves hers' on year-round and it has lasted ten years.

My concern here would be overheating during the day. Not at all unusual to run heat at night and have to throw open doors and vents during the day w/fans.
I really don't think you could leave it on during the summer months here if you plan to use your greenhouse for anything during the summer.
