The bubble sheets are flat on the edges for stapling. I just curled them up inside the door panels and they hold. The "kit" was just a few rolls of the bubble stuff from Lowe's Depot. A door is X feet wide, there are Y panels to each door and you've got Z garage doors. That tells you how many feet of bubble wrap you need, and measure the height of each panel- there should be a size that's an inch or so wider and it'll do.

It makes a huge difference. I used to have 4 100 watt bulbs in the garage that I'd leave on overnight during real cold snaps to keep heating pipes in the garage ceiling from freezing. Now 4 CFLs are enough. I haven't worried about sealing between the panels because simply insulating the panels themselves was such an imprvement.
