    • Fire protection curtains

      Fire protection curtains

      In case of fire, fire protection curtains close wall and ceiling openings. Their construction (roll-down or folding technique) and the use of different fabrics provide for a wide range of applications as well as different protection goals, classifications and time classes. The casing and guide rails of the highly flexible systems blend almost invisibly into the building and allow plenty of scope for sophisticated architecture and open room concepts.

    • Conveyor system closures

      Conveyor system closures

      Various production and logistics processes call for the most diverse types of conveyor systems. If these conveyor lines pass through fire-retardant or fire-resistant walls or ceilings, the openings required for this purpose must be provided with fire protection closures to prevent the spread of fire through the conveyor system or the goods conveyed. In the event of fire, conveyor system closures (CSC for short) must close these openings immediately and automatically. Fire resistance classified according to DIN EN 13501-2 is just as important as the smooth clearance of the closing areas in the event of a fire.

    • Smoke curtains

      Smoke curtains

      A smoke apron is a part of a smoke control system which also includes other components such as natural smoke and heat exhaust ventilators (EN 12101-2) and mechanical smoke and heat exhaust ventilators (EN 12101-3). Smoke aprons restrict the movement of combustion gases within a building in case of fire.

    • Smoke protection curtains

      Smoke protection curtains

      Once closed, smoke protection curtains (SPC) restrict the passage of smoke during the phase of fire formation, so that in the event of a fire, there is enough time to rescue people and animals from the room behind the curtain and to recover material assets without the need for respiratory equipment.

    • Tube sealings

      Tube sealings

      The solution for issues with fire protection dampers in ventilation and air conditioning systems in conveyor processes. Stöbich offers fire protection for pneumatic conveyor lines the closing elements of which are not exposed to the flow of conveyed material. This way, the closing element cannot be damaged or contaminated by abrasive conveyed goods.

    • Control units

      Control units

      Each automatic fire protection system needs a control unit. They are critical to safety, because a failure of this function means that the entire investment into a fire protection sealing has been in vain. Control units coordinate both fire detection and interaction with other control units, such as higher-level building control systems or clearing of the closing area of conveyor system closures.

Size dimensions and system design

Due to the combination of classifications or the ratio of clear system width to clear system height, the stated maximum dimensions may be reduced and the dimensions of the enclosure and guide rails may vary. The specifications on the quotation apply.

Component (supporting structure) in which the closure may be installedAchievable fire resistance class
clear wall opening
clear wall opening width
clear wall opening height
High-density solid wall, masonry or solid concrete
with total density of ≥ 800 kg/m3 and a thickness of ≥ 150 mm
EI2 90from 500 mm to 6,000 mmfrom 500 mm to 4,400 mm
Low density solid wall, aerated concrete with total density
of ≥ 450 kg/m3 and a thickness of ≥ 150 mm
EI2 90
from 500 mm to 6,000 mmfrom 500 mm to 4,400 mm

The installation situation must comply with the building code requirements of the country of installation. The fire resistance of a ceiling or wall support structure and the adjacent components must at least cor- respond to that of the fire protection closure. Proof of the stability and serviceability of the adjacent walls and components must be provided under general ambient conditions and in the event of fire. See also notes on the standard supporting structure in EN1366-7:2004 or EN1363-1:2020. The fire protection system must not be subjected to any additional loads other than its own weight, even in the event of fire.
