For those that are after more space to spread out, the Alu Group / Schüco Folding Design sliding doors allow indoor spaces to blend with outdoor areas in the blink of an eye. Expanses of glazing become passageways. The door leaves slide to one side with ease, forming flat, narrow stacks. This is thanks to roller carriages that are guided silently across rails in the floor and ceiling. It is up to you which way you would like your sliding door to fold. Our flexible systems can be adapted to your needs to save space. And if you need to make a quick exit, you can use an optional integrated balcony door.
