Ultraline Sliding Door Configuration Options
The Ultraline Slim Sliding Door is available in various configurations that can be tailored to suit your architectural requirements.
You have the option to create a completely open corner sliding door, or choose a pocket sliding door configuration, where the door neatly slides into a wall cavity.
Alternatively, you can pair the sliding doors with fixed glass-to-glass corners to create a frameless corner, for a real architectural statement.
Take full advantage of the large panels, with individual sizes of up to 4.2 metres wide or 3.2 metres high and up to 9 m².
You also have the choice of single-, double-, triple-, or quad-track configurations, depending on your design requirements.
