Large-format sliding doors open onto a covered terrace in low golden afternoon light

Sliding doors

Large-format glazed openings, specified by track configuration — the panel weight and the track that carries it, not the glass.

A sliding door is a structural question dressed as a glass one. Panels this size are specified around weight: what the rollers carry, what the track resists, and how the meeting stiles seal when two moving panels have to close against each other.

The family runs from ND-01 — an interior-only system for kitchens and studies — to exterior systems carrying 100 kg sashes up to 2.7 m tall, in two-, three- and four-track configurations.

Inside the frame

The same system, cut open. This is what sits behind the plaster once the trim goes on — and it is where a window succeeds or fails.

A multi-track sliding system cut through the meeting stiles
Track configuration6 tracks narrowEach panel gets its own track. Track count is what sets how wide the opening goes and how much of it clears.
A window frame cut open in driving rain, showing the concealed drainage chamber in the sill
The hidden drainage pathRain driven at the frame collects inside the sill chamber and leaves through a concealed slot, instead of running down the face of the window.
A narrow-frame section cut through the sash and outer frame
The narrow sightlineHow little frame you can see is a function of how much structure sits behind it. This is the section that lets the sightline run slim without losing rigidity.
The hardware rebate of a window frame, hinges and locking points visible
Hardware in the rebateHinges, locking points and the friction stay sit inside the rebate, out of sight and out of the weather.

Performance

Specified by track configuration and panel weight rather than a wind grade — the heavier sections carry up to 100 kg a panel and are rated by the supplier for balcony doors with good wind resistance under gale.

What a specific opening achieves depends on its size, exposure and installation. That is why we assess the opening before we specify the system.
