flo-motion® telescopic doors


Flo-Motion telescopic doors schematic render

The telescopic door was primarily designed as an "in-line" package to fit entirely within the structural reveal depending on the wall thickness. The pre-assembled frame incorporating the support bar can be installed at the first fix stage allowing other trades to complete the walls and floors before the panels are fitted.
The two sliding leaves are connected by a sequencing device so that the primary leaf (fast door) reaches the fully opened or closed position at the same time as the secondary leaf (slow door) reaches its pre-set position.

  • Unique support bar for ease of installation
  • Hinged pelmet for ease of access
  • Offset track system for ease of maintenance
  • Option of narrow or wide door stiles

Glazing options include:

  • Single glazing – 6.4, 8.8 and 10.8mm clear laminate
  • Double glazed units – 28.8mm (6.4/16/6.4)
  • Double glazed units with manually operated integral blinds (32.8mm)
  • Solid Infill panels

The original doorset was designed with 100mm stiles to compliment the other doors within the Flo-Motion® range.  The 55mm stile was introduced where space is limited and a larger clear opening and a more slim-line design is required.

Structural Opening DimensionsRefer to door parameters.

Clear Opening Width – Approximate distance between frame and leading edge of door when in the fully open position.

Clear Opening Height - Approximate distance between bottom of pelmet & FFL.

Handing - For example and as shown above - viewed from the pelmet side, door opening is on the left.

Standard telescopic doorsets normally consist of two sliding doors and one fixed panel, all of equal widths.

With certain applications, it is possible to achieve an even greater clear opening width by increasing the width of the "fast" door and reducing the width of the "slow" door and fixed panel. This is a "be-spoke" item and is only offered with clear or obscure double glazed units.

Suitable reinforcement (structural steels) will be required to accept the load and this will be discussed at the design stage.

To help you select the ideal doorset for your project, why not use our Clear Opening Calculator for guidance.

Bespoke applications - please contact us to discuss any doorset outside of the normal parameters or if extended glazed screens are required.
