Automatic drop seals

Imagevideos

Universal M-12

Pivot L-15

Swinging pivot doors without frames are mostly used in prestigious offices and buildings as well as in private homes. Architects use them as an elegant solution for large, heavy doors or as an alternative to mobile partition wall systems.

Stadi delayed drop

To avoid pressurisation when closing the door, selected Stadis are available with an optional mechanism, which delays the dropping of the seal.

Stadi

Whatever demands are placed on a seal: the Stadi meets them. The latest version of athmer's sealing range for metal and system doors made of PVC, steel or aluminium is so versatile and adaptable that it covers a wide range of applications.

Nadi®

Nadi® is suitable for retrofitting and improves the sound insulation values. In addition, it upgrades existing fire doors to smoke protection doors.

Schall-Ex® 

The Schall-Ex® is the classic drop seal. Thanks to the tool-free adjustable sliding release, time is saved during installation.

Schall-Ex® - fitting

The new generation of seals can also be installed much faster and thus more cost-effectively. Thanks to a standard sliding actuator mechanism that can be adjusted without tools, there is no longer any need to invest time in attaching a protective pressure plate - even on lacquered timber frames.

Nadi® LM - fitting

The set for reveal mounting. The heart of Nadi® is the spring-loaded seal. The system thus ensures that the door always closes tightly - even if the door is thermally deformed.

Nadi® FM - fitting

The set for flush mounting. Nadi® meets the requirements of DIN 18095 as well as the new European standard EN 1634 for use as retrofit smoke protection for existing fire doors.

How to shorten an automatic drop seal

If you pay attention to the side of the seal and the specified short dimension, a door seal can be cut to the appropriate length of the door.


Finger protection

NR-32 UniSafe® 

Every day, unnecessary accidents happen at doors that are not or insufficiently secured. With athmer finger protection systems, trapping fingers between the door leaf and frame can be effectively prevented.

NR-32 UniSafe® - fitting

With the new click system, the installation of the NR-32 UniSafe® is very easy and also enables the fabricator to install the fastening rails and the finger guard at different times. Furthermore, the click system allows for easy maintenance and cleaning of the door.

BA-28⁺- fitting

BA-28⁺ is a hinge-side protection profile for top hinges on aluminium doors. It is suitable for securing the secondary closing edge on the hinge side.

BU-K⁺ - fitting

The adapted profile geometry and the adjustable 2D fastening element ensure easy assembly/disassembly. Readjustment is also possible and thus offers ideal protection for the door on the hinge side.


Technical centre

In our technical centre, we test the sound insulation value of your products as well as their resistance to air, driving rain and wind load. We accompany and advise you in the various stages of your product development - always with the aim of getting your product ready for the market quickly, efficiently and in the highest quality.

The test facilities

Building acoustics

In our sound test stand, we can collect sound insulation values for joints and building elements such as doors, gates and windows. The laboratory meets the requirements of EN ISO 10140 and consists of three rooms that together form an L-shape.
The sound test laboratory is supervised by the experts from ift Rosenheim, who also supported us in its planning.

Smoke protection

We use mechanical clamping elements to mount your product in our smoke protection test stand. There it has to prove its functionality: The smoke tightness is tested at ambient temperature and at an increased temperature of 200 degrees. Furthermore, we record whether the element deforms. The test specimen meets the standard if its leakage rate is less than 20 m³/h for single-leaf doors and 30 m³/h for double-leaf doors.

Burglar resistance

In accordance with the applicable standards EN 1628, EN 1629 and EN 1630, we test how well your building element withstands manual burglary attempts and how it reacts to dynamic and static loads. The first step in the static test is to apply a compressive force of up to 15kN at specified load points, depending on the resistance class. Then we check whether the element can withstand repeated blows from a 50 kg pendulum.

Continuous function

Open, close, open, close - we test how your single or double-leaf door behaves in continuous operation in accordance with the applicable standards EN 1191 and Din 4102-18. For this purpose, we install your product in the test device and subject it to a permanent load. This way, your customers can also be sure that your products will do their job for many years and are thus a long-term and safe investment.

Air, wind load and driving rain

Our air, wind and water test stand meets the requirements of the applicable standards of DIN EN 1026 and DIN EN 1027 and is calibrated annually by an independent laboratory. For the test, we clamp your building element - for example exterior doors, gates, windows, roller shutters and facades - precisely into the twelve square metre test facility. A flexible grid system makes it possible to create a customised frame for your product.

Temperature resistance

In accordance with the applicable standards EN 1628, EN 1629 and EN 1630, we test how well your building element withstands manual burglary attempts and how it reacts to dynamic and static loads. The first step in the static test is to apply a compressive force of up to 15kN at specified load points, depending on the resistance class. Then we check whether the element can withstand repeated blows from a 50 kg pendulum.
