12.03.2018, 25 years of Thermix warm edge

What started off as a purely niche area is now indispensable in windows: the warm edge. Until the 1990s, spacers made of aluminium were predominantly used for insulated glazing. 1993 marked the birth of Thermix GmbH, the first manufacturer of hybrid spacers made of plastic and steel and thus one of the first alternatives to metal spacers.

At that time, there was virtually no demand for warm edges. If there was any at all, it was only for passive house windows, but these were a playground for very few idealists at the time. However, company founder Wilfried Ensinger saw the potential for much more in the Thermix spacers that were produced at Ensinger right from the start. Initially, plastics specialist Ensinger participated in Thermix GmbH before taking over the company completely in August 1997.

The introduction of Germany’s Energy Saving Ordinance (EnEV) in 2002 gave the thermally optimised spacers a significant boost because since then, the thermal properties of spacers have had to be taken into account in the calculations as part of the verification process of the EnEV.

Over the last 25 years, Ensinger has continuously been further developing the Thermix spacers and adapting them to increasing requirements for energy-efficient windows. We will carry on doing this in the future, too. You can continue to rely on innovations and further developments related to the warm edge.

02.03.2018, Meet Thermix: Klaus Esser

Loyal to Thermix since 2005: Sales Manager Klaus Esser

Klaus Esser has been assisting and advising Thermix customers for 13 years. As Sales Manager he is responsible for sales covering a large region: Northern Germany, the Benelux states, Scandinavia and the Baltics all lie within his area of responsibility. Above all, his customers appreciate his reliable, honest and humorous manner.

Esser looks back over his many years of experience in sales. Even before he joined Ensinger in 2005, the 46 year-old already had many years of experience in sales of windows and industrial doors. He is a man of conviction: "I find sales fascinating, even and especially in a fiercely competitive market such as that for warm edge spacers. Successes carry more weight as a result," says Esser. "I also enjoy having contact with other people and the travel opportunities that come with my job."

Permanently on the road during the week, the father of two (12 & 9) enjoys spending time with his family on weekends. Alongside joint activities he also enjoys his motor boat and sailing.

Klaus Esser is always willing to listen. You can contact him by telephone on +49 151 19 54 03 31 or by e-mail at

23.02.2018, New Website, New E-mail

With its high-performance plastics, Ensinger is now represented globally at 33 sites and in numerous industries. As a result of this growth, our old corporate website was out of date. To ensure that Ensinger’s digital presentation is contemporary and globally consistent, we completely revised our website last year. Why not take a look: Any country versions that are still missing will gradually be converted to the new design.

Please note: Following the launch of our new corporate website, our e-mail addresses have also changed. In future, you can contact Thermix employees at

01.02.2018, Thermix is Exhibiting

The 2018 trade fair year has already started for Thermix at the beginning of March with Pencere Eurasia Window in Istanbul. That was only the beginning, however. We have other important events lined up:

The Federal Flat Glass Association (BF) and the Multi-Pane Insulating Glass Quality Association (GMI) have invited us to this year’s Glaskongress in Leipzig on 11th and 12th April. "Guests can expect the latest topics, exciting presentations, highly interesting discussions and an accompanying special exhibition. This is a great opportunity to talk shop or simply to exchange ideas," says BF Managing Director, Jochen Grönegräs. It’s also a great opportunity for us to be there with Thermix.

At China Glass, which takes place in Shanghai between 19th and 21st April, we will also be exhibiting our spacers and muntin bars. We will be pleased to welcome all parties interested in Thermix on the LiSEC stand our sales partner in China.

And then, of course, there’s glasstec! Naturally we will also be present in Düsseldorf in October. Preparations are already under way for the world’s leading trade fair, but we’re not giving anything away here just yet

The trade fair year ends in November with VETECO 2018 in Madrid.

If you are planning to visit any of these trade events, we hope you will find the time to drop by the Ensinger stand. The Thermix team will be pleased to answer your questions. To see where you can find us at any one of these events, go to our Trade fair calendar.

04.12.2017, Sales Under New Management

New Thermix Sales Director: Rolf Friedrich Buhl

Rolf Friedrich Buhl has been managing the sales of Thermix since 1st November 2017. Ensinger is delighted to have gained such an experienced and successful individual who is committed to sales. With his professional career, Buhl has precisely the right experience to promote Thermix even further on a global scale, having consistently worked in leading positions in international sales and business development. His professional activities have taken him all over the world. He has worked as a mechanical engineer in South Africa and in the United Arab Emirates, among other places. However, he left his heart in Asia: he spent the last ten years living and working in Hong Kong and Singapore.

The 54 year old is initially pursuing his objective of promoting Thermix shares in a globally expanding market by visiting customers. Alongside getting to know them, he wants to understand their needs and concerns so he can plan the way forward accordingly. "Honesty, fairness and reliability take absolute priority, both when working with customers and with my team," emphasises Buhl. "In spite of everyday stress, you have to enjoy work as well. After all, a motivated and enthusiastic team is crucial for building and intensifying customer relationships."

With his new office at Thermix in Ravensburg, this well-travelled manager is returning to his roots in the Lake Constance region. Born and raised in Friedrichshafen, directly on the shore of the lake and on the edge of the Alps, water and mountains are key elements of his hobbies: windsurfing and paragliding. However, during European winters, these are quite literally put on ice.

You can contact Mr. Buhl on +49 751 354 52 16 or by e-mail at

29.11.2017, RAL Quality Mark for Thermix

Products with the RAL quality mark meet the highest quality requirements. They assure planners and builders that they have purchased a durable and high quality product. A product that has been put through its paces. The quality mark gives consumers an unmistakeable, easily identifiable measure of quality, offering them security and protecting them in the long term from any unpleasant surprises.

The German Multi-Pane Insulating Glass Quality Association monitors and guarantees insulated glass with the RAL quality mark. Manufacturers who want to label their insulated glass accordingly have to comply with the quality and inspection regulations of the Multi-Pane Insulating Glass Quality Association.

The RAL-GZ 520 quality and inspection regulations from May 2016 introduced both in-house and external monitoring of the components of insulated glazing, i.e. also for warm edge spacers. Insulated glass bearing the RAL quality mark may only contain such quality-controlled components.

Thermix spacers are among these monitored components that are allowed to be installed in RAL-marked insulated glass. In practice, this means that spacer samples have to be taken directly from the insulated glass manufacturer and tested by an independent institute. The German State Materials Testing Institute Darmstadt (MPA) is the appointed independent test institute.

With Thermix, you can therefore rely on consistently high quality. That’s why we offer excellent warranties for our products. Find out for yourself.

02.11.2017, Ensinger Foundation: Helping People Help Themselves in Nigeria

Graduated students of the Ensinger-supported school in Nimo, Nigeria.
The Wilfried and Martha Ensinger Foundation has a mission to provide long-term support for social, scientific and cultural projects.

The Wilfried and Martha Ensinger Foundation has been supporting a school project in the village of Nimo in Nigeria for the past 20 years. With its help, a primary school was initially built that is now attended by 525 children. In addition to buying medical devices, the foundation has also helped finance a drinking-water well and the construction of a secondary school. The "Viktor Frankl New Dimension Secondary School" was ceremoniously opened in 2011. This summer, the oldest students had the opportunity to take their final examinations for the first time. 31 school leavers can now obtain the university entrance qualification in accordance with the West African WAEC standard.

Successful Model for Education

The two well-equipped schools have turned into a successful model, not least thanks to highly committed and qualified teachers. Several students have already won trophies in competitions for speaking, maths and writing essays. Those students who do not want to go to university can also obtain a vocational qualification at the secondary school.

Long-Term Promotion of Children and Adolescents

The commitment of Wilfried and Martha Ensinger for the Ensinger family business that they founded has always accompanied support for people in Germany and overseas. The married couple started the first relief projects in Brazil back in the 1970s. Numerous activities were added after the Wilfried Ensinger Foundation was founded in 1997. Most of the projects, including the construction of schools in developing countries and the promotion of cultural programs and educational institutions in Germany, have been supported over many years and benefit children and adolescents in particular.

Additional funding priorities and projects of the Foundation:

25.11.2016, Thermix inside: The warm edge for Canada

Thermix inside: University Hospital Research Centre, Montréal, Canada

Prelco Inc. is a leading Canadian manufacturer of glass products with a wide range of articles in the commercial glass, industry and transport sectors. In Prelco's insulating glass it is Thermix spacers that provide the warm edge. A few years ago now the company, which is headquartered in Montreal, decided to refine its products across the board in the form of an improved spacer. Thanks to its impressive performance values, a decision was made in favour of Thermix. Since then, under the brand R-MaxTM, it is an integral part of Prelco insulating glass units and consequently in the relevant information pack for architects. This makes the R-MaxTM, aka the Thermix spacer, the preferred Warm Edge spacer on the Canadian market today. Some impressive references provide proof of the cooperation between Ensinger and Prelco, which is greatly valued by both parties.
