Short answer
Motorisation often becomes more useful as curtain width, height, finished weight and daily operation increase. A large sliding door still needs a complete treatment design: curtain, track, stack, opening direction, motor, fixing and access to the door must work together.
01
Design the stack and door clearance first.
A curtain can move smoothly and still obstruct the door when open. Confirm where the fabric gathers, whether it clears handles and the main walking line, and whether a one-way or centre-opening arrangement best suits the furniture and traffic path.
The track line may need to extend beyond the glass to preserve usable opening. That decision changes total span, wall support, motor position and the amount of fabric needed, so it belongs in the early measure—not at final installation.
02
Specify from the finished load.
Fullness, face fabric, lining, heading and any double treatment all contribute to finished weight. The chosen motor and track must be checked against their documented configuration and load limits; a generic maximum width is not a substitute for that assessment.
High glazing also changes maintenance. Ask how the motor, power point or charging connection can be reached later without dismantling a finished ceiling or unsafe access.
03
Choose the treatment that suits the opening.
Curtains bring softness and can cover a broad elevation, but they need side stack and room for the moving fabric. A motorised roller blind may be more compact where there is little side space; a Roman blind gives a different visible stack above the glass.
For a heavily used sliding door, rehearse the open and closed positions against handles, furniture and the route outside. That simple walk-through can be more useful than a motor catalogue.

What changes the recommendation?
CCBD should resolve the usable door opening and the finished curtain before selecting a motor. The specification should name the exact track and motor after dimensions and load have been confirmed.
