How do sectional garage doors work?

The short answer

A sectional garage door is made of horizontal hinged panels that rise vertically in tracks and park flat under the garage ceiling. Because nothing swings outward, you can park right up to the door — and the 40 to 45mm foam-filled panels make it the best-insulated door type as standard.

The longer answer

As the door opens, rollers on each panel follow a track up the sides of the opening and curve back along the ceiling, so the door stacks overhead rather than tilting out. That geometry is what gives sectionals their two practical wins: no swing arc on the drive, and a proper seal around all four edges of the opening.

It also makes them natural candidates for automation — an operator simply drives the door along tracks it already runs on. See the sectional garage doors page for prices and specifications, or the sectional vs roller comparison if you are weighing the two.
