New technologies. New requirements. New standards.

In the technical centre, we are not only at your side as an advisory service provider, but also as a development partner.  

The technical centre

The world of doors is constantly changing - we are actively shaping this change. The technicians and engineers in our development team rely on the latest technologies - always with the aim of improving the quality of our drop seal and finger protection systems even further. 

More than 150 worldwide patents and utility models are impressive proof of our innovative strength. To further strengthen this, we cooperate with renowned testing institutes. In addition, our engineers are involved in various standards committees of the German Institute for Standardisation (DIN). In this way, we contribute to establishing new standards in the world of doors.

We have also been a reliable partner for our customers for over 60 years. With us, agreements apply - without ifs and buts. We are committed to quality: Good doors deserve the best seals, good customers deserve the best service. 

The cooperation

At the technical centre, we are not only at your side as an advisory service provider, but also as a development partner: with "concurrent engineering", an innovative and effective form of teamwork, we work on your new product in parallel with you throughout the entire development process and also involve your suppliers if necessary. In this way, new products can be brought to market extremely quickly and without detours. High costs for faulty designs or repeat testing are a thing of the past.

Based on your concrete requirement profile, we start the development work for your product parallel to you. Once an initial product sample is available, we test it in the technical centre for the desired properties. In several development loops, we continue to optimise the product samples. At the end of each cycle, a further test is carried out in the technical centre. This allows us to see directly whether we are on the right track and, if not, to take immediate countermeasures.

Let us bring your new product to market quickly and cost-effectively.

The test benches

Sound insulation

In our sound insulation 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 acoustic signals from the two outer rooms are sent to the centrally located reception room. The rooms are separated from each other by a modular partition wall system and a concrete wall. Both walls have a test opening that can be quickly and flexibly adapted to the element to be tested. This allows us to test components of any size.

The sound test laboratory is supervised by the experts of ift Rosenheim, who also supported us in its planning. The employees of the renowned institute determine the sound insulation values of your test specimens and carry out their final sound insulation test.

Air, wind and water

How tight does your product hold up when exposed to draughts, driving rain or high wind loads? Does it meet all the requirements? And where might there still be potential for optimisation? With the help of our air, wind and water test stand, we can provide you with answers to these questions. For the test, we clamp your building element - for example exterior doors, gates, windows, roller shutters and façades - precisely into the twelve square metre test facility. A flexible grid system makes it possible to create a customised frame for your product.

We then measure how the test specimen reacts to short blasts of air, a constant air or negative pressure, as well as to continuous sprinkling through several nozzles. Does it withstand the water? And does it deform due to the air pressure of up to 700 Pascal? Thanks to a fog machine, we are also able to perform a leakage test.

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.

Continuous function

Do your doors stand for quality and durability? Do you know whether your products can withstand continuous stress and are free of damage and fully functional afterwards? We give you certainty in the permanent function test stand of the technical centre. 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.

Open, close, open, close - we test how your single or double-leaf door performs in continuous operation in accordance with the applicable standards EN 1191 and Din 4102-18. To do this, we install your product in the test device and subject it to a permanent load. An engineer regularly records any abnormalities in the protocol: Do the operating forces increase? Does the material fatigue? Or does the closer fail? In order to successfully pass the continuous function test, interior doors must complete 200,000 test cycles and exterior doors 20,000 test cycles without complaint.

After the test, you will receive a detailed test report from us, on the basis of which we can advise you, for example, on the selection of seals for your products.

Smoke protection

Smoke protection doors can save lives. To do so, they must effectively prevent threatening quantities of toxic smoke from entering a room or spreading to other rooms. To find out whether your product optimally meets these requirements and complies with the applicable standards DIN 18095 and EN 1634, we subject your single or double-leaf door to a smoke protection test in our Athmer technical centre.

Using mechanical clamping elements, we 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 element 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. In addition, smoke control doors must also pass a continuous function test.


While the number of successful burglaries has fallen in recent years, the number of failed burglary attempts has risen constantly. Currently, around 45 % of attempted burglaries in Germany fail, which is not least due to improved security measures. How effectively entrance doors, windows and other building elements protect against burglary is therefore becoming increasingly important as a quality feature and sales argument.

How is your product doing in terms of burglary protection? In our technical centre, we test how well your building element withstands manual burglary attempts and how it reacts to dynamic and static loads in accordance with the applicable standards EN 1628, EN 1629 and EN 1630.

For this purpose, we clamp your doors, windows, curtain walls, lattice elements or closures in our test stand. First of all, during the static test, a compressive force of up to 15kN is applied at specified load points, depending on the resistance class. Then we check whether the element can withstand repeated blows from a 50 kg pendulum. Finally, we test the resistance to manual break-in attempts. For this purpose, an employee - using the tools and time specifications provided for this purpose - carries out the test. The test specimen must meet the requirements of the desired resistance class.

Finally, we evaluate your test specimen and provide you with valuable information on how you can further optimise your product with regard to burglary protection.

On a voluntary basis, the Technikum has undergone the "Airborne Sound" reference measurements of the Physikalisch-Technische Bundesanstalt (PTB). The measurements are based on comprehensive reviews of the sound insulation comparison measurements for test centres that are recognised for issuing general building authority test certificates. For the assessment of the measurements, the test centre result was compared with a reference value as well as the critical limits.

The evaluation of the PTB results showed that the requirements of the sound insulation comparison measurements were met in full. The validity of the verification is three years.

In order to offer customers the highest level of testing reliability, the technical centre always strives to meet the highest standards. This includes regular, independent inspections of the test benches and the existing technical equipment as well as their operators. In addition to a modern standard, this also enables the reproducibility of measurements.

About the PTB:

The Physikalisch-Technische Bundesanstalt (PTB) is one of the leading institutes in metrology and is the supreme authority in the Federal Republic of Germany for all aspects of metrology. The basis of the comparative measurements are the "Guidelines of the Physikalisch-Technische Bundesanstalt (PTB) for Sound Insulation Comparative Measurements" (version June 1999) and the standards valid for the respective measurement methods. The guidelines have been drawn up by the PTB in agreement with the Deutsches Institut für Bautechnik (DIBt) and the Verband der Materialprüfämter e.V. (VMPA). (VMPA) word

Once again this year, the German Design Council honoured forward-looking innovations with the German Innovation Award - and this year we are among the winners.

The technical centre convinced the jury as a consulting service provider in the field of product development for the door, window and facade industry and won in the competition class "Excellence in Business to Business" in the category "Machines & Engineering".

The German Innovation Award honours cross-industry products and solutions that distinguish themselves above all through user-centricity and added value compared to previous solutions. Because forward-looking innovations are not always immediately recognisable at first glance. How the path to the digitalised future can be mastered is shown by the approximately 700 competition entries in 40 categories. As an independent and internationally active institution, the German Design Council is committed to the competitiveness of companies.
