Good reasons to try Hörmann fire-rated and smoke-tight sliding doors
High-quality door appearance
Hörmann sliding doors 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.
Precise door leaf guide
The cylindrical track roller and the stable track roller, in conjunction with the patented track, work together to provide an optimal force balance. Quiet operation and easy actuation is ensured, thanks to a suspension with ballbearing. The track can be precisely adjusted in three dimensions using adjusting screws. A track panel in the colour of the door leaf results in a harmonious overall appearance.
With convenient operator solution
The combination of a steel or stainless steel sliding door with the SupraMatic HT or ITO 400 operators allows quick opening and closing during daily operation. The operators SupraMatic HT and ITO 400 FU with soft start and soft stop as standard are recommended for a particularly quiet and low-wear door travel. The door can be conveniently operated via a hand transmitter, push button or key switch. In the event of a fire, a patented mechanism releases the operator. The door is then closed reliably through weights.
