Jansen's soundproofing roller door is certified according to DIN EN ISO 140-3 by the MPA Braunschweig. To achieve higher soundproofing values two roller doors, one at each side of the fall, are installed. The distance between is at least 260 mm. This double-door-solution reaches a soundproofing value of Rw,p = 51 dB.
To achieve soundproofing values of Rw,p = 54 dB the door leafs are additionally covered with an acoustic hood.
Both roller door solutions are available up to a height of 4.000 mm.
The door leafs consist of 114 mm high aluminium hollow section profiles with soundproofed filling. The separate slats are joined to a shell via a turnable connection system. The thickness of the elements is 26 mm.
The guide rails consist of zinc-coated sheet steel in a screwed construction.
Plug-on drive with built-in retainer or sprocket drive with separate retainer. In case of a power failure the door can be operated via an emergency crank. Opening and closing speed: approx. 0.11 m/s. Maintenance-free drive unit.
