- 40mm insulated panels
- Full perimeter weather seals
- Glazed panel options
A sectional garage door lifts in hinged panels and runs back along the ceiling, which is why it is the standard door across newer Centurion housing. The estates and later developments through Midstream, Amberfield, Thatchfield, Copperleaf, Southdowns and Rooihuiskraal North were built with the headroom for it, and it gives the best seal and the best appearance of any garage door type.
Sectional garage doors we supply in Centurion
- Steel sectional doors in ribbed, panelled and flush profiles.
- Insulated sectional doors with a foam core for garages used as living or work space.
- Aluminium and glazed sections where the door is part of the elevation.
- Timber and timber-look finishes, which several of the estates specify.
Headroom and side room
A standard sectional door needs around three hundred millimetres above the opening and clear space each side for the tracks. Where a Centurion garage does not have it, low-headroom track kits solve most cases and a roll-up door solves the rest. We check at survey rather than on installation day.
Square openings, and what to do when they are not
A sectional door is a rigid assembly and it needs a reasonably true opening to run properly. On the settled ground common in parts of Centurion we either correct the frame or recommend a shutter instead. Forcing a sectional door into a twisted opening produces a door that binds, wears its rollers and eventually takes the operator with it.
Matching an estate specification
On estates through Midstream, Southdowns, Cornwall Hill and Copperleaf the door profile and colour are usually fixed by the architectural guidelines. We identify what is currently fitted, build the matching profile, and provide the written specification for the committee before manufacture.
Insulated sectional doors
An insulated door makes a real difference where the garage is a workshop, a gym, an office or a flatlet. Insulated panels are also stiffer and considerably quieter, which matters on a wide double and matters more where the garage shares a wall with a bedroom.
Sealing against dust and storms
Sectional doors seal better than any other type because the panel face sits against the frame all the way round. Bottom, side and head seals keep out dust and driven rain, which is the complaint that brings most people to replace a door that still opens perfectly well.
Springs, balance and safety
A sectional door is balanced by torsion assemblies, and that balance is what protects the motor. We rate them to the door mass and the cycle count, fit cable safety devices where the design calls for them, and check the balance by hand at every service.
What a sectional garage door costs in Centurion
Priced on width and height, panel type, insulation, finish and automation. Single and double doors are quoted separately because the balance and operator specification changes with the mass.
Common questions
About sectional garage doors
Around 300mm to 450mm of clear space above the lintel for a standard track, though low-headroom kits recover part of that. Measure to the ceiling or the nearest beam, whichever is lower, and send us the figure before you order anything.
The panels are hinged and run on rollers in a track rather than curling around a barrel, and the section joints seal against each other. On an insulated door the foam core also damps the drumming that makes a single-skin door boom.
Yes. Glazed panels can go into any section, most often the second row down so daylight comes in at eye level. Toughened, frosted and tinted glass are all available, and an aluminium-framed full-view door is a step further again.
They have more moving parts than a tip-up door — rollers, hinges, cables and springs — so an annual service matters more. In exchange the wear is spread across many small parts that are cheap to replace individually.
