Lift & slide doors for large openings
A large opening is a hardware and threshold decision long before it is a glass decision. The LS-60 carries 6,000 mm of clear opening on one track, moves a 300 kg leaf on roller bearings with one hand, and keeps the floor line flush — the three numbers that make a wall disappear rather than a door open.
The envelope, from the LS-60 spec
These figures are the system’s own catalogue data, read straight from theLS-60 specification — the same numbers the quotation and shop drawings reference.
- 75 mm thermal-break aluminium, multi-chamber
- 6,000 mm single track, up to 4 leaves
- Up to 300 kg per leaf
- 10–16 mm tempered or laminated, IGU or monolithic
- Flush, barrier-free (DIN 18040 compliant option)
- Multi-point locking, vent-height integrated grip
- Anodised, powder-coated, RAL on request, wood-grain film
- Tested to EN 14351-1, EN 13830, EN 16005; AS 1288 glass option
Configuration notes
What actually changes between one project and the next on this application.
Single track, up to 4 leaves
To 6,000 mm of clear opening. The configuration most villa and restaurant walls converge on.
Multiple sets on parallel tracks
Openings beyond 6,000 mm are resolved as sets on parallel tracks rather than one oversized leaf — each set keeps its own tested hardware.
Corner assemblies
Two runs meeting at the corner, with the fixed panel taking the turn so both leaves slide clear of the meeting point.
Flush barrier-free threshold
The floor line continues inside and out; the DIN 18040 option is specified where accessibility applies.
One-hand operation
Sashes lift on roller bearings before sliding — the mechanism that lets a 300 kg panel move with one hand.
Pre-glazed sashes
10–16 mm tempered or laminated, IGU or monolithic, glazed and gasketed in the factory before crating.
Application questions
What is the real maximum opening?
6,000 mm of clear opening on a single track with up to four leaves, each leaf up to 300 kg. Wider elevations are configured as multiple sets on parallel tracks — the drawing office resolves the split at shop-drawing stage.
How does a 300 kg leaf move by hand?
The sash lifts on roller bearings before it travels, so the dead weight is off the track when the panel moves. That is the mechanism behind the 300 kg capacity figure, and the reason the system is specified on walls that are opened daily.
Does the threshold really stay flush?
Yes — the flush threshold is the standard configuration, with the barrier-free DIN 18040 option specified where accessibility applies. The floor line continues inside and out, which is why the opening reads as a wall rather than a door.
Which test route applies?
The system is tested to EN 14351-1 and EN 13830 with the AS 1288 glass option for Australia; the report for a project references the configured models on that order, not a standing certificate.
