      Fire protection curtains

      Fire protection curtains are seal openings in walls and ceilings in case of fire. The constructional set-up (rolling- or folding technology) and the use of different fabrics offer a wide application spectrum as well as different protection targets or classifications and time classes. Casings and side guides of those flexible applicable systems are integrated almost invisibly in the building and provide much scope for design of sophisticated architecture for opened designs.

    • Conveyor system closures

      Conveyor system closures

      Manifold production - and logisitc processes require different construction types of conveying systems. If the haulage drifts are passing through fire-retarding resp. fire-resisting walls or ceilings, the necessary openings must be provided with fire protection closures to avoid the expansion of the fire by conveyor technique or by conveyed material. In case of fire the conveyor system closures have to seal those openings immediately and automatically. Thereby a classified fire resistance as well as the smoothly clearing of the closing area must be respected in case of release.

    • Smoke curtains

      Smoke curtains

      A smoke curtain is part of unit keeping areas free from smoke and may include building parts like natural smoke and heat venting systems and automatic smoke and heat venting systems. Smoke curtains restrict the movement of fire gases inside a building in case of fire.

    • Smoke protection closures

      Smoke protection closures

      In closed condition smoke protection closures restrict the passage of smoke in the phase of fire formation so as to enable the rescue of people, animals or materials assets in case of a fire in the room positioned behind it without the need of breathing protection.

    • Tube sealings

      Tube sealings

      The solution to problems with fire protection dampers for ventilation and air conditioning systems in conveying processes. Stöbich offers fire protection for pneumatic conveying lines where the closing elements are not exposed to the flow. Thus, damage or contamination of the closure element is avoided by abrasive conveyed goods.

    • Controls

      Controls

      Control systems are necessary for all automatic fire protection systems! They are safety-relevant, because without their function or in the event of a malfunction, the entire investment of a fire protection partition would be useless. Controllers coordinate both fire detection and the interaction with other controls, like superordinate building control or the retraction of the closing area at conveyor closing area.

      Médiathèque Charles Nègre | Grasse, France

      The Médiathèque Charles Nègre in Grasse, France, is an impressive example of contemporary architecture that reflects the cultural and historical importance of the region. The information center with space for education, culture and encounters was opened in 2011 and designed by the renowned French architecture firm Marc Barani. The building combines modern aesthetics with the traditional architecture of Provence, creating a harmonious link between old and new, for example by combining modern materials such as glass and steel with local natural stone. The generous window fronts create an atmosphere flooded with light. Ecological sustainability is achieved through natural ventilation and the resulting reduction in energy consumption; green spaces are also integrated on various levels. Our <a href="/us/solutions/fire-protection-curtains/stoebich-fire-smoke-curtain-hc"><b>➥ horizontal Fire and smoke curtain hc</b></a> fire protection curtains fit perfectly into this marvel of contemporary architecture. They securely close the ceiling openings in the event of a fire, but otherwise remain invisible and let in plenty of light and air. Copyright attribution: © Ivry Serres

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.
