Crafting Tomorrow: The Award-Winning Schuco FD 75/90 Bifold Door

Imagine a door. Not just any door, but one that stands as a testament to what’s possible in design and functionality. This isn’t about what BiFold doors have been; it’s about what they could be. The Schuco Aluminium Doors, recipients of the REDDOT design award, invite you to gaze through a wider lens – up to 1500mm wide and 3600mm high.

We’re talking about engineering that doesn’t just fill a space in a wall but redefines the wall itself. These doors are a bold statement in luxury and innovation, with panel widths reaching 1500mm, surpassing the conventional by a significant margin.
