development and innovation

New Technologies. New Requirements. New Standards. The world of doors is constantly changing – and we are actively involved in shaping this change.

The technicians and engineers in our development team use the latest technologies – always with the aim of further improving the quality of our door seals and finger protection systems. More than 150 patents and registered designs worldwide clearly demonstrate our innovative capability.

To further strengthen this, we cooperate with renowned test institutes. Our engineers are also engaged in various standards committees of the German DIN standards institute. In this way, we are actively involved in establishing new standards in the world of doors.

We have also been a reliable partner for our customers for more than 60 years. For us, contracts and agreements apply without any ifs or buts.

We are committed to quality: Good doors deserve the best seals, and good customers deserve the best service.

In our Technical Centre, we test the sound absorption capacity of your products and their resistance to air, driving rain and wind loads. We support and advise you in the various stages of your product development – always with the aim of getting your product onto the market quickly, efficiently and with the highest standard of quality.

Acoustic testing facility

In our acoustic testing facility, we can raise the sound insulation values for joints and construction elements such as doors and windows. The laboratory meets the requirements of EN ISO 10140 and comprises three rooms which together form an L shape.

The acoustic signals from the two outer rooms are sent to the centrally located receiving room. The rooms are separated from each other by a modular partition wall system, in one case, and by a concrete wall, in the other case. Both walls have a test opening which can be quickly and flexibly adjusted to suit the element to be tested. This allows us to test components of all sizes. The acoustic testing laboratory is monitored by ift Rosenheim, who also helped us to design the laboratory. The staff of this renowned institute determine the sound insulation values of your test object and carry out the final sound insulation test.

We will be happy to provide advice on how you can optimise your products with respect to sound insulation. Give us a call!

Air, wind and water testing facility

How airtight and watertight is your product when subjected to draughts, driving rain or high winds? Does it meet all the requirements? And what potential is there for optimisation? With the help of our air, wind and water testing facility, we provide you with the answers to these questions. For the purpose of the test, we fit your doors, windows, shutters or façades, for example, precisely into the twelve-metresquare test facility. A flexible grid system allows us to create a tailor-made frame for your product. We then measure how the test object reacts to short blasts of air, to a constant air pressure or vacuum, and to persistent rain applied via several nozzles. Does it withstand the water? And does it deform under an air pressure of up to 700 pascal? Thanks to our fog machine, we are also able to test for leaks. Our air, wind and water testing facility complies with the requirements of standards DIN EN 1026 and DIN EN 1027. It is calibrated annually by an independent laboratory.

Naturally, we also advise you on how you can further improve the air and water tightness of your products. Please give us a call!
