Fire-proof scrolling shutters are custom-made according to the customer’s dimensional requirements. They are tested according to European standards (ČSN EN) and can be supplied in various versions.
Thanks to its simple structural design, the installation takes up a minimal amount of space. The horizontal lamellas, manufactured from high-quality galvanized zinc-plated sheet profiles, are joined together by a locking joint. The lateral guide rails ensure smooth vertical movement of the scrolling shutter. The doorjamb and header are lined with an insulation profile produced from an intumescent material.
Insulated lamellas each 150 mm tall and 60 mm thick with a perfectly interrupted thermal bridge insulation density of 30 kg/m3 for the EI 60 class door insulation density of 35 kg/m3 for the EI 120 class door considering the large diameter of the rolled-up shutter, the motor is always placed outside the drum and power is transferred through cog wheels placed on the shafts of the drum and motor individual lamellas can be fitted during the installation can also be used for sound insulation diameter of rolled-up shutter: 670–950 mm certified without requiring a cover for the rolled-up shutter
non-insulated thin-walled sheet lamellas each 100 mm tall the motor shaft can be attached directly to the shaft of the main drum (does not apply for FS motors) drum and shutter can only be installed as a single unit diameter of rolled-up shutter:310 – 500 mm certified without requiring a cover for the rolled-up shutter.
combination of insulated and non-insulated lamellas that slide horizontally with a perfectly interrupted thermal bridge for the insulated lamellas
the non-insulated lamellas, which are scrolled onto the drum, drag the insulated lamellas along a horizontal steel structure (similar to sectional doors) benefit of maintaining a low head (450 mm) and high fire resistance for doors the motor shaft can be attached directly to the shaft of the main drum (does not apply for FS motors) can also be used for soundinsulation diameter of rolled-up shutter: 310 – 500 mm
