    High Quality Construction

    Hörmann sliding doors provided by 4Ddoors offer a modern door appearance through a patented V groove at the element joint without visible screw connections. The high stability is ensured through the interlocked, toothed labyrinth plug-in profile. The elements are 72 mm wide, fully glued and flush, and aligned with each other through threaded rods. This creates a high-quality door leaf with parallel, uniform-width borders. The individual elements are up to 9 m high and are produced from a single piece without any weld seams. This results in a high-quality door appearance.
