Sectional, roller or Flex‑A‑Door: which suits your garage?
The shape of your opening and the space above it decide more than looks do.
The short answer
- Sectional suits most homes and openings from 2.4 m to 6.6 m wide.
- Roller suits openings up to 3.2 m wide, with about 400 mm above them.
- Flex‑A‑Door replaces a tilt door and needs as little as 80 mm above the opening when opened by hand.
Start with the opening
Two measurements decide most of it: how wide the opening is, and how much space there is between the top of the opening and the ceiling, called headroom. Style and colour come after.
| Door | Opening width | Space above |
|---|---|---|
| Sectional | 2.4–6.6 m | From 200 mm with a low-headroom kit; 320 mm standard |
| Roller | Up to 3.2 m | About 400 mm |
| Flex‑A‑Door | 1.2–3.15 m | From 80 mm, opened by hand |

How each door moves
A sectional door is made of hinged panels that rise and then slide back along the ceiling, so you can park close to it inside and out. A roller door rolls up into a drum above the opening, so there are no tracks along the ceiling. Flex‑A‑Door is a roller curtain on a curving track that lies flat near the ceiling, and it fits behind the opening rather than in it.
Near the coast
New Zealand noteGarador advises against window insets in coastal environments, because salt air is hard on them.
Washing the door regularly matters more near the sea too. Garador suggests clean water and a cloth every 14 days, and more often in salty areas.
