No matter how well-insulated your garage workshop is, chances are good that air leaks around the garage door, so you lose heating or cooling efficiency. But a couple of toggle clamps mounted at the sides of the door can help hold it firmly against the weather seals at the edges. Mount the clamps on wooden blocks sized to clear the door’s roller tracks. You don’t need a lot of clamping pressure to create a good seal. Disengage the clamps before opening the door, of course; the toggle clamps will make this easy.
