Panel / Section — Garage Door Glossary | D&L Garage Doors
**Panel / Section**: One of the horizontal panels that make up a sectional garage door, connected by hinges that allow the door to flex along the track. Understanding this component helps homeowners make informed decisions about garage door maintenance, repair, and replacement. Below, D&L Garage Doors explains what a panel / section is, how it works, common misconceptions, and when to call a professional.
What Is a Panel / Section?
A sectional garage door is made up of individual horizontal panels (typically 4 to 5 sections for a standard 7-foot or 8-foot tall door). Each panel is connected to the adjacent panels by hinges, and rollers on each side guide the panels along the tracks. When the door opens, the panels flex at the hinge points and travel from vertical (closed) to horizontal (open) along the curved track sections. Individual panels can be damaged by vehicle impact, weather, or age without requiring replacement of the entire door. However, panel replacement depends on the availability of matching panels from the manufacturer — discontinued models may not have replacement panels available. Panel construction varies: single-layer steel, steel with polystyrene insulation, or steel-polyurethane-steel sandwich construction. The choice affects the door's insulation value, durability, noise characteristics, and cost.
Common Misconceptions About Panel / Sections
There are several widespread myths about panel / sections that can lead to costly mistakes or safety hazards. Here's what you should actually know:
- Myth: A dented panel is just cosmetic. Reality: Damaged panels can compromise the door's structural integrity, insulation, and weathersealing.
- Myth: You can always replace individual panels. Reality: If the door model is discontinued, matching panels may not be available.
- Myth: All panels are interchangeable. Reality: Panels are specific to the door model, manufacturer, and position in the door.
Safety Warnings
Safety is paramount when dealing with garage door components. Keep these important warnings in mind:
- Do not attempt to remove or replace panels with the door under spring tension.
- Damaged bottom panels can allow water and pests to enter the garage.
