RParts Vacuum Panels Grade F

When I first refurbished the boat I was smitten by Vacuum Panels. They were to provide several times the effective insulation of Blue Board and last 10 years. What could be better? After 13 years of cruising I was about to find out. I removed the lids I purchased from RParts knowing that the panels would be no more insulating then the blue board anyway. I had purchased some new space age material that wouldn't degrade (at least not as much to my knowledge) over time. Low and behold I found a sloppy install of the vacuum panels. Sloppy indeed. So much so that parts of the area really had no insulation. For me, I wouldn't purchase the lids with vacuum panels installed. Rparts VP Grade F
