Smoke-protection door

Teckentrup smoke-protection doors

Smoke creation is a hazard  to life.

Smoke is just as dangerous to life as fire. In the event of an accident, even just a few breaths of the hot and toxic smoke gas lead to unconsciousness or death. Both the fire and the smoke are extremely dangerous and must be reduced or inhibited by smoke protection doors in an ideal situation. As soon as a fire breaks out in a room the smoke protection doors, which are tested per DIN 18095, close automatically through the use of door closers.

Smoke protection door for your safety

A smoke protection door is tasked with preventing the entrance of smoke for as long as possible in the event of fire. They are used, for example, to separate hallways with a length of at least 30 meters as well as in stairways and hallway closures. This creates smoke-free zones and escape or emergency routes so people can leave and evacuate the respective building. Smoke protection doors must, like fire protection doors, close by themselves and be equipped with a latch lock and a circumferential seal. They can be kept open only with a specially approved hold-open device. The doors must be equipped with special locks that have a spring latch.

How long will the protection hold?

With fire protection doors, the protective effect (fire resistance time) is limited by time. With smoke protection doors, this cannot be stated with certainty. This is because the tolerated smoke volume depends on the ventilation conditions (the air transfer rate) and the size and height, primarily, of the respective room, among other things. Roughly speaking, an approximately 30 metre long hallway can be passed through safely without wearing a respiratory device for about ten minutes, with the current limit values and so-called incipient fire.

How is the door structured?

Smoke protection doors are equipped with seals that go around three sides. They are made from various materials such as steel, glass or wood. On the bottom section, they are equipped with a retractable bottom seal. Per DIN 18095, double-leaf doors must have a door closer on every leaf and a so-called door selector.

Where are smoke protection doors required by law?

Smoke protection doors are required by law in various buildings, enterprises and certain public facilities. According to DIN 18095, they must ensure a free and, above all else, safe escape path. In recent years, it has been shown that the most common and greatest danger is the progression of smoke, not heat, in the event of a fire. The doors produced for this function are made in accordance with applicable standards. Your specialist retailer can also provide suitable accessories, such as profile cylinders, wall plug packages or screws or fittings approved by building authorities. Generally speaking, doors for smoke protection must be labelled as such at the factory. Before they are sold, they must comply with DIN 18095, since this was implemented by building authorities and applies Germany-wide.



Can smoke protection doors be upgraded?

Yes, using a suitable retrofitting system makes it very easy today to retrofit an existing fire protection system with smoke protection functionality. Before this is done, however, relevant building authorities must be contacted in order to plan each step.

A smoke protection door can ensure that dangerous smoke is retained for as long as possible in the event of fire. This allows people to leave the building easily without having to wear protective equipment. Using a special retrofitting system, you can easily upgrade existing fire protection systems into a smoke protection door. However, you must speak with the relevant building authorities to go over each planned step. The doors are produced in accordance with applicable standards and must meet certain requirements.

A special seal on three sides and the floor seal adapted to the particular application securely prevents the penetration of smoke. State-of-the-art door technology guarantees convenient automation and reliable safety. Teckentrup doors are used in private, public, and industrial areas. Single-family homes and large apartment buildings also enjoy our protection, along with clinics, cinemas, businesses, offices, parking garages, and schools.

Hotel Radisson Red Cape Town

Radisson Red, Cape Town

Tourism booms worldwide, especially in popular destinations. New hotels spring up everywhere like mushrooms! This can be seen on the other side of the world too: in Cape Town, at the thrilling port metropolis at the foot of Table Mountain, the Rezidor Hotel Group opened, under the new “Radisson Red” label, a high-profile 4-star hotel with a modern interior.
Elbe Philharmonic Hall

Elbe Philharmonic Hall

In a building such as the Elbe Philharmonic Hall first-class products are not only installed where they are visible and aesthetics matters but everywhere. In a concert hall with an auditorium capacity of up to 2.100 spectators the escape routes for instance require time-consuming planning. In such a superlative building interior design in every detail counts. Thus the doors are chosen due to their functionality and due to their aesthetic criteria: Fire protection and smoke protection have to be harmonised with the creative claim of a flush view.

The recently renovated 'schloss Colditz' in Saxony, Germany is a great example of how to reconcile the often conflicting demands of historic preservation and fire-protection. For example, many of the passageways have been fitted with the Teckentrup T30 all-glass doors, which combine functionality with aesthetics and maximum transparency.
