Sectional garage doors in Cranbourne & Casey.

• B&D Firmadoor (single-skin Colorbond): Budget end. Solid for low-cycle garages and rental properties. ~$1,800–$2,400 single installed.
• B&D Panelift / Steel-Line Standard (double-skin insulated): The mid-range default. Insulated steel-foam-steel panel, quiet, well-sealed. ~$2,400–$3,500 single, $3,000–$4,500 double installed.
• B&D Panelift Icon / Steel-Line Premium (premium insulated): Thicker panel, premium internal skin, longer warranty, smoother operation. ~$3,500–$5,500 double installed.
• B&D Aero Timber / Steel-Line Cedar-Look (timber-look insulated): Insulated steel with convincing printed timber-grain outer skin. Zero maintenance, looks like timber. ~$4,200–$7,500 double installed.
• Western Red Cedar / Pacific Cedar (genuine timber): Real timber sectional, beautiful, needs oiling every 12–18 months. ~$6,500–$11,000 single or double installed.

Why sectional is the modern default.

• Lifts vertically: doesn’t arc out into the driveway like a tilt door — you can park 200mm from the door without it hitting your bumper.
• Better insulation: double-skin insulated panel is R-2.5 to R-4.0, vs single-skin Colorbond at R-0.5. Big difference if the garage is attached to a heated/cooled house.
• Quieter operation: the panel resonance is absorbed by the foam core. Combined with a belt-drive opener, the whole door operates at ~50 dB.
• More headroom inside: the door slides flat along the ceiling, so you keep full headroom under the open door (unlike a roller, which bunches into a drum at the front).
• More secure: 18–42mm thick interlocking panels in steel tracks. Can’t be levered off the wall.
• Custom sizes: any width 1.8–6.0m, any height up to 3.0m, in 10mm increments.

Insulation levels.

• Single-skin (non-insulated): R-0.4 to R-0.6. Cheapest. Fine for detached garages and rentals.
• Double-skin polyurethane foam (insulated): R-2.5 to R-4.0. The standard for attached garages and habitable-room-above-garage layouts.
• Triple-skin / premium foam (heavily insulated): R-4.0 to R-5.5. For workshops, gyms, garages converted to teen retreats.

Low-headroom track kit (for older Casey garages).

Standard sectional door tracks need ~300mm of headroom above the closed door. Older Casey garages (1980s–2000s in Hampton Park, Endeavour Hills, Cranbourne township) often have 2.1m ceiling heights with 2.0m openings — 100mm of headroom isn’t enough for standard. Solution: a low-headroom track kit reconfigures the cable drums and trolley to need only 100mm above the door. Same door, same opener, same warranty. Adds $350–$500 to the standard install.
