I heat my garage shop full time, and when I'm outside on dark winter nights, I can see a lot of light between the weather stripping and the overhead door. Light = lost heat = untold dollars' worth of BTUs pouring outside. The problem is that there's so much space between the rollers and the track that the door doesn't stay tight against the weather stripping. I just invested in the Green Hinge System to solve the problem. The design is simple but brilliant. Each replacement Green Hinge has a built-in spring that pushes the door against the weather stripping for a much better seal. The hinges also quiet the door because the rollers don't rattle around in the track. It's a well-made product and I fully expect it to cut my heating costs this winter. A set of six hinges costs about $85. Go to greenhingeofamerica.com to look them over and choose the right ones for your door size.
