New GEALAN systems in the testing process

With GEALAN-COMFORT® and GEALAN-KONTUR®, two new products were presented at the International Future Forum 2022. The market launch of both the floor-level threshold and the premium design system is currently being intensively prepared. An important part of the work still to be done: The GEALAN products are being extensively tested.

To get a sense of what "extensive" means at this point: a total of 32 tests - 16 of them at GEALAN, just as many off-site - are scheduled for the second half of 2022 alone to prepare the new GEALAN-KONTUR® profile system for market launch. What is being tested? Kay Sommermann, head of testing at GEALAN, explains: "We started with development tests. These were tests with GEALAN-KONTUR® prototypes, in which we tested breaking loads of the centre dome in our technical centre. To do this, we loaded different designs with a compression die in order to be able to track force introduction into the geometries. Furthermore, burglary tests were also carried out; here we worked with tools for burglary classes RC2 and RC3. These include screwdrivers, wedges or the so-called "cow's foot"." GEALAN-KONTUR® is, after all, designed with special attention to not letting intruders into the four walls. "Currently, the first so-called air-water-wind tests are underway, and we are also doing these in our test laboratory. Here, extreme loads on the system are simulated, such as a hurricane would bring."

The new GEALAN-COMFORT® threshold solution has already passed these tests, as Kay Sommermann reports: "We tested the single-leaf door up to 600 Pascal. In this case, that is the measure of driving rain tightness. And because no one can imagine what that means: That's as strong as hurricane Kyrill, which covered house roofs at 110 kilometres per hour in January 2007 - and during the tests, not a drop of water is allowed to get through the door to the inner room side."   

The tests will begin - as described - on prototypes, starting with tests in GEALAN's own house. Later, GEALAN partners are also involved, as in the case of GEALAN-COMFORT®, the companies Gretsch-Unitas (GU) and Athmer, who contribute relevant system know-how as well as the mechanical drop-down seal and conduct informative endurance tests in their rooms. "This provides us with a broad picture of results and thus a high degree of reliability for our customers," explains Andreas Linke, group leader in GEALAN product management, adding, "These tests not only have a laboratory character, but our new developments are literally put through their paces here."

The tests that the Institut zur Prüfung und Zertifizierung von Bauprodukten, Sicherheitstechnik und Schutzausrüstung (ift) Rosenheim accepts are decisive. Kay Sommermann: "Certain measured values are specified in order to obtain a CE mark. No window may be sold in Europe without the corresponding parts being marked. However, we go beyond these minimum requirements with our values."   

Until this is achieved, there are repeated in-house tests, followed by adjustments, and then further interim tests. With GEALAN-COMFORT®, for example, testing of single-leaf doors began in September 2021; until the beginning of the year, adjustments were made again and again to further improve the system to meet the highest requirements. At the same time, the tests of stile doors were started.

In addition to the described tests for burglary protection, wind and driving rain resistance, extensive tests for sound insulation, fall protection and suitability for long-term use are also scheduled. How extensive are the tests? "Individual air-water-wind tests take about an hour per cycle, but are repeated several times a day after minor adjustments. But there are also test cycles for the continuous use of adhesive systems, for example, which last over six weeks," explains Kay Sommermann.   

Basically, if you want to put new products or systems to the test, you first have to have the so-called run-in samples before you can start the tests. These are the first processable profiles that are made available for the pilot and test phases via the high-performance run-in technical centre of the GEALAN tool shop. A complete system test ultimately takes over a year.

But even existing systems are tested at GEALAN from time to time in order to further develop them. Or when system additions become available, for example the wet bonding process is supported with new products in the programme - then Kay Sommermann and colleagues in the testing laboratory are again in demand for extensive tests.

Working for the future

Talking to GEALAN about sustainability is fun because nobody in this company is satisfied with simple answers. And because bright minds ask important questions, think about things carefully to seek good solutions, and then actually implement them. GEANOVA met with four of these clever people.

The revolution after the defeat

A sombre silence fills the car. A frustrated Ahmet Çak and his colleague Gyula Lélek have been driving on the Hungarian M1 motorway for about half an hour. The customer they had visited terminated their collaboration after hearing about a price increase. Çak just recently took over as Head of Sales for Hungary and negotiated new terms with all customers. Now, however, he has lost this one window manufacturer as a customer and suffered a defeat. The Annahegyi motorway restaurant at the MOL petrol station in Budapest serves a nice espresso so they exit the motorway. The frustration gives way to defiance over coffee and Çak motivates his colleague: ‘We’ve got to learn from this defeat!’ A ‘magic moment’ as he will later refer to it.

A strong bond

Neckties have been slung around the necks of men and women for centuries. It is a fashion accessory and style icon with its own holiday – International Necktie Day: on 18 October, the guards of honour in the Cravat Regiment ride through Zagreb and decorate statutes with cravats to send the message that neckties are Croatian. It’s even said that in the 17th century France’s King Louis XIV took a liking to the ‘à la manière croate’ (Croatian-style) cravats that Croatian mercenaries wore. The Sun King introduced the piece of uniform to Parisian society. The flagship store of Croata, a specialty shop for ties and scarves, is located in the Oktogon Passage in Zagreb’s city centre. GEANOVA met Klaudija Čota and Robert Križanović there. 18 years spent working together at GEALAN Croatia connects them, just like a tightly tied knot in a necktie.
