Automatic sliding and telescopic doors both provide powered access, but their leaves open in different ways and create different clear passage widths.
Automatic Sliding or Telescopic Doors? Differences and Applications overview
How standard sliding doors work
The leaves of a standard automatic sliding door move sideways and usually collect at the sides of the opening. This can suit entrances with enough wall space beside the doorway. The number and direction of the leaves are selected to match the building.
When to consider a telescopic door
A telescopic system uses multiple leaves that slide behind one another as the door opens. It may be considered where side space is limited but a wide clear opening is needed. Suitability depends on the opening dimensions and the supporting structure.
What determines the right choice?
Consider the entrance width, available side space, pedestrian traffic, accessibility requirements and existing frames together. A site survey and project review are the best way to identify the appropriate door type.
