SMOKE CURTAINS - To prevent
the horizontal spread of smoke

Rigid smoke curtains

Greater fire safety in buildings

By far the greatest danger in a fire is not the development and spread of the fire, but the rapidly spreading smoke gases. In order to prevent the spread of smoke in the building in the event of a fire, it is necessary to form smoke compartments in buildings. This is particularly important for buildings with a high volume of people, such as large event venues, or in the industrial sector, where the smoke would cause less damage to people than to property due to the high room height. 
If the smoke compartments are not structurally ensured, they can be formed via smoke curtains. Smoke curtains counteract the lateral flow of smoke and hot, toxic fire gases: In the event of a fire, the smoke curtains drop and channel the smoke to confine it to a specific section area. This means that people can be safely evacuated from the building and the fire brigade can quickly locate the source of the fire thanks to better visibility.  

Smoke curtains provide greater safety 
This is how smoke curtains work: In large-area halls, no significant overpressure can build up under the roof in the initial phase of the fire. However, this is crucial for the effectiveness of a natural smoke and heat exhaust ventilation system. The rising smoke gases spread under the roof. They cool down and flow back down in the form of smoke rolls, where they become a life-threatening hazard near the ground. 

    Smoke curtains divide a hall into several smoke compartments and thus prevent horizontal smoke spread in the roof space. In addition, the curtains are also used for targeted smoke control. 
    The dimensioning of a natural smoke exhaust ventilation system according to DIN 18232-2 requires that the smoke compartments are not larger than 1,600 m² or are divided by smoke curtains into areas with a maximum of this size. The distance between the smoke curtains or between the wall and the smoke curtain must not exceed 60 metres. Further subdivisions (e.g. closed beams) within the smoke compartments have no influence on the dimensioning.

    Technical details of the product

    Smoke curtains

    Designs 

    roda smoke curtains are made of flame-resistant, tightly woven glass fibre material. The lightweight housing of the smoke curtains is made of galvanised steel sheets, anodised aluminium alloy or colour-coated to match the design. Smoke curtains restrict the spread of smoke to a defined area in the event of a fire. 

    Rigid smoke curtain SMOKETEX 

    The roda smoke curtain “SMOKETEX” is a rigid smoke curtain made of polyurethane-coated, flexible glass fibre fabric with grey aluminium pigmentation. This fabric with a thickness of approx. 0.40 mm has a base weight of 0.455 kg/m² ±10%. The standard smoke curtain consists of vertically arranged individual elements that are sewn together with a non-combustible yarn for a maximum curtain area of 45.00 m². Individual curtains are available in widths of between 800 mm and 5,950 mm and can be extended horizontally to the maximum curtain area by means of push buttons, depending on the design. The C-shaped ceiling mounting profile consists of a multi-folded, 2 mm thick hot-dip galvanised steel sheet.  

    The SMOKETEX rigid smoke curtain meets the requirements for CE marking in accordance with Annex ZA3 of DIN EN 12101-1. For the conformity assessments, the procedures specified in the standard were carried out. The certified smoke curtain was tested at a temperature of 620 °C for 151 minutes, is smoke-tight according to the test report and has received the classification designation “D150” due to its compliance with DIN EN 12101-1. Upper and lateral gap dimensions are stated as 0 mm.

    Installation 

    Our roda smoke curtains are characterised by simple assembly, which guarantees fast and, above all, safe installation. The installation of our roda smoke curtains is carried out on site with pre-punched ceiling mounting profiles made of steel sheet. For the ceiling fastening, only means approved by the building authorities under fire exposure may be used. 
    Steel tubes are pushed into the sewn-in pockets of the curtain material and the lower pipes are connected with push-in sleeves. The upper tube is used for fixing to the ceiling profile, whereby the locking brackets screwed to the mounting profile prevent the curtain from slipping out. The lower tube also serves to weigh down the smoke curtain.  

    In order to prevent deflection of the smoke curtain and to neglect gaps, our smoke curtains are 

    • connected to each other by push buttons, 
    • to be placed between double-sided brackets, 
    • to be connected to the lower edge of the single bracket, or 
    • to be fixed in the lower corner area in case of masonry projection. 

    Reliable partner in case of emergency 

    Our roda smoke curtains are made of flame-resistant, tightly woven glass fibre material. International and national test certificates confirm the excellent properties of the smoke curtain material. Constant production controls guarantee the highest level of consistent quality.
