      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

Smoke control in atria

Smoke control in atria

SMOKE CONTROL IN ATRIUMS

They are the heart of shopping centres, hotels or office complexes, bring light into many a building and connect the individual floors: atriums such as the ➥ InnovationSPIN in Lemgo impress with their open architecture with daylight utilisation, a special indoor climate and natural acoustics over several floors.
Here, the compatibility of functionality and aesthetics, fire protection regulations and construction methods is particularly important: How can atria be effectively sealed off from fire and smoke to protect people and property without losing the aforementioned properties?

InnovationSPIN, an extraordinary co-working space

The InnovationSPIN in Lemgo is the "think tank for SMEs". The OWL University of Applied Sciences, the district of Lippe and the district craftsmen's association work hand in hand here on new ideas. This special type of collaboration is also reflected in the architecture: open space concepts and shared offices, workshops and laboratories bring all participants together according to the InnovationSPIN principle - with the atrium as the centrepiece.

THE CHALLENGE

Fire protection should work, but not be conspicuous

Structural fire protection systems must be installed in such a way "that the development of a fire and the spread of fire and smoke [...] is prevented and, in the event of a fire, the rescue of people and animals as well as effective extinguishing work are possible."
(§ 14 Fire Protection/Building Regulations)


According to fire protection regulations, the structural separation of building sections is necessary. The classic means are often solid structures such as walls or fire doors. But how can open room concepts be realised without the visual disruptions that such conventional solutions present? And how can the vital smoke-free escape and rescue routes be created?

To do this, you first need to understand how fires can spread in atriums. Click on the following graphics to start a simulated smoke development.

Atrium without compartmentalisation

This highly simplified model drawing shows how smoke would theoretically spread if the source of the fire were decentralised and there were no fire protection elements. In this case, the smoke would spread floor by floor, starting from the source of the fire. Only with a supply air source does the smoke escape via the smoke/heat extraction systems (SHEVS) in the ceiling area - the so-called "chimney effect". The spread of the highly toxic fire gases in the atrium to other floors is not prevented.

Conventional solution: permanent partitioning

If the floors are partitioned off with fixed fire protection elements, e.g. using fixed glazing, the smoke is channelled through the atrium directly to the SHEVS.
Smoke does not enter the floors and escape routes; however, permanent compartmentalisation also interferes with the building design and affects the appearance, acoustics and indoor climate. The open character of the atrium is restricted.

The STÖBICH solution: flexible compartmentalisation

Only in the event of a fire alarm do the fire and smoke protection curtains from STÖBICH lower fully automatically from their housings, which in turn are concealed in the ceiling. All floors are sealed off equally so that no gases or flames can spread to the other floors. The smoke is channelled directly to the SHEVS by the permanent partitioning. People can reach the outside via escape and rescue routes. The effect of the atrium can fully unfold during normal building operation.

Advantages: Smoke barriers from STÖBICH are installed invisibly and create in atriums ...

    -  ... free lines of sight
    -  ... maximum utilisation of daylight
    -  ... an improved indoor climate over several floors
     -  ... acoustics that connect building areas
    -  ... almost endless design possibilities

THE SOLUTION

Fire and smoke protection curtains are ideal for open room concepts

Textile fire protection systems from STÖBICH can be installed almost invisibly in ceilings and also offer more scope for building planning thanks to their low weight, small footprint and simple installation.

40 Fiberseal smoke protection curtains in InnovationSPIN Lemgo

The special concept of collaboration between different institutions in InnovationSPIN is supported by the architecture. The different work areas can be seen from the large atrium and are connected by a sculptural, illuminated staircase. Should a fire break out here, a total of 40 Fiberseal smoke protection curtains close all floor openings.
When closed, the textile fire and smoke protection closures prevent the passage of flames and smoke for up to 120 minutes and reduce heat radiation (classification EW 120 in conjunction with S200). This allows people in the rooms behind to escape to safety via existing stairwells within a reasonable time, even without breathing protection.

With ➥ Stoebich Smoke Curtain T, even very large room openings and atriums can be sealed smoke-tight, both as standard and customised solutions such as in the InnovationSPIN or in the following reference example, an office building with an event area for the Südwestmetall Neckar-Fils district group in Esslingen, where two 5-sided room-forming smoke barriers ➥ Smokeshield-S with different angles were installed. With the ➥ textile fire and smoke protection barriers from STÖBICH, you remain flexible!
