## Two Systems, Two Different Problems

Buyers often frame this as a budget question, but full-automatic and semi-automatic (telescopic) sliding doors exist to solve different problems. Full

 solve traffic: they open hands-free for every visitor, all day, driven by a motor and sensors. 

Telescopic sliding doors

[/semi-automatic-telescopic-doors/ →](/semi-automatic-telescopic-doors/)

 solve geometry: their overlapping panels open a wide entrance in a wall that has no room to park a full-width sliding leaf.

Get the problem right and the choice usually makes itself.

## The Comparison That Matters

| Factor | Full Automatic | Semi-Automatic Telescopic |
| --- | --- | --- |
| Starting price | From RM2,000 | From RM1,700 (incl. frame + laminated glass) |
| Operation | Sensor-triggered, hands-free | Assisted manual glide |
| Best for | High pedestrian traffic | Narrow entrances needing wide openings |
| Opening width | Limited by side wall space | Overlapping panels maximise clear width |
| Power required | Yes (with backup battery option) | No |
| Moving parts | Motor, belt, sensors, rollers | Tracks and rollers only |

> Measure the wall beside your opening. A single automatic leaf needs roughly its own width of wall to park against when open. If your wall is shorter than that, telescopic overlap is how you win the width back.

## When Each One Wins

**Choose full automatic when traffic is the priority.** Clinics, offices, retail with steady footfall, and any premises serving elderly or disabled visitors benefit from hands-free entry. The continuous-duty 100W BLDC motor, anti-clamp safety and backup battery earn their cost every busy day. Accessibility expectations increasingly assume powered entry for public-facing premises.

**Choose telescopic when width is the priority.** Tight shopfronts, side entries and corridors where a standard slide could only ever half-open are telescopic territory. The RM1,700 starting package — aluminium frame plus a 4 x 8 feet laminated glass panel with cover — makes it the value pick where powered operation is not needed. For what moves either number upward, see our guide on

.

**Traffic and tight walls together?** Automatic telescopic configurations exist: motorised multi-panel systems that combine hands-free operation with overlap-gained width. They cost more than either base option, and we spec them case by case.

One honest warning in each direction. A telescopic door at a genuinely high-traffic entrance becomes a chore — someone is always nudging it. And a full automatic door bought purely because it feels premium, at a quiet side entrance, spends money on a motor that opens for ten people a day.

The deciding inputs are your opening width, side wall length and daily footfall — three numbers our RM50 on-site measurement captures exactly, with the fee deducted from whichever system you order.

## Frequently Asked Questions

Is a telescopic door cheaper than a full automatic door?

Yes at entry level — telescopic systems start from RM1,700 including aluminium frame and laminated glass, versus RM2,000 for full automatic systems. But they solve different problems, so price alone shouldn't decide.

Which opens wider in a tight space?

Telescopic. Its overlapping panels park in a fraction of the wall space, clearing far more of the opening than a single sliding leaf can in the same wall.

Which suits high traffic better?

Full-automatic with a continuous-duty motor. Sensor-triggered hands-free operation handles constant pedestrian flow that a manually assisted door cannot.
