I have a two car garage so I had to purchase two kits. I went on Ebay and found the same foam stuff that Lowe's sells, only cheaper. It came from Georgia in two large boxes. I spend about a day installing the panels AND new rollers. The panels just need to be scored with a razor blade and the trimmed part snapped off. There are grooves/slits in one side of the panel that allows it to flex and fit into the door panels. The hurricane support struts are easily removed with a socket wrench to give you easier access to the panels. No adhesive was used. The difference in temperature in the garage is significant. Before I did it, I actually burned my elbow on the door one day from the radiant heat from the sun on the door. One side of the foam is finished with a white, smooth surface that can be easily wiped clean. Some sort of laminate coating. The price was a great savings, with the shipping FREE. Only tool I needed was a razor blade to score the foam and a socket wrench to remove and replace the hurricane support beam. Easy DIY job.
