Before and after of my garage doors. I used the kits from http://www.energyefficientsolutions....tion_Kit.html#
and there was an extra 4+ ft of roll left over. I used self drilling screws to hold the sheets to each individual panel, then sealed them with foil tape. Took a little longer than I expected, about 4hr for both doors, but I was trying to avoid screwing up. Greased up the rails and chains while I was at it. It feels noticeably warmer inside the garage, but I haven't measured before/after temps.
