Our next‑generation sliding door.
The APX Evolution is our flagship minimal‑sightline sliding door , a reference product across European residential architecture. The opening sashes sit fully embedded inside the frame profile, leaving an interlock between closed panels of just 25mm. At that thickness, the vertical line between two meeting panels is barely visible.
Individual panels can weigh up to 500kg each and measure 3.5m × 3.5m. That means single sheets of glass over 12m² are well within the system’s engineering tolerance , at which point the door stops being a door and starts being a moving wall.
Motorised. Pocketed. Cornered.
The Evolution platform is configurable in ways standard sliding doors simply are not. Pocket (Galandage) versions slide the panels completely into a wall cavity, so the opening disappears. Corner versions slide two panels at 90° into each other, opening the entire corner of the building. Motorised variants open at the touch of a button.
0.88 W/m²K whole‑door U‑value, 43dB acoustic attenuation, Class 4 air permeability, C5 wind resistance , all at the very top of what any sliding door achieves. This is the door we specify when the client wants the best full stop.
