In this part of the expert interviews series we interviewd Ing. Thomas Stangl, Managing Director and co-owner of the Ing. Rudolf Duschek GmbH gesprochen.

The company Duschek was founded in 1926 by Mr. Ing. Rudolf Duschek in Vienna and is active in the fields of heat, cold and sound insulation, fire protection, interior construction and boiler and oil tank cleaning. At present the company Duschk is represented Austria, Graz, St. Pölten. In 2004 the first foreign branch office was established in Croatia. Other foreign activities are currently in Germany, the Czech Republic and Romania and are managed by Austria.

What are the main tasks of Duschek GmbH?

The activities of the Duschek GmbH are, on the one hand, the insulation of cables against heat and cold losses, which are installed by installers. These include heating pipes, plumbing pipes, cooling pipes or ventilation ducts. On the other hand, we are active in the area of fire protection. In essence, we carry out the work of the craftsmen, but an intensive cooperation with the planning officer is inevitable.

Which sectors / industries offer the highest potential for measures in the area of heat and cold insulation?

In addition to residential construction, insulation measures play an important role in industry. In principle, appropriate measures must be taken by all companies which transport energy in any form, whether in heat and / or cooling lines. In many cases, these are steam lines which require corresponding insulation. Examples are the wood processing industry, which operates with large amounts of steam, or industrial areas that use conditioned air as a carrier. A further area of application of our services is in factories that are able to recover the existing waste heat with the least possible losses and recover it by means of a heat exchanger. There are already areas of large industrial plants with heating ducts of two meters in diameter and more.

Our customer base is roughly divided into residential and industrial sectors. Furthermore, insulation measures are carried out both in new buildings and in renovation projects. Here, however, the new buildings or new industrial plants predominated.

One area that is gaining in importance is the cold insulation. Air conditioning systems are used more and more frequently in the office building, and an appropriate insulation is necessary for efficient operation. However, refrigeration processes are also becoming more frequent in process technology. In addition to the energy saving, a significant focus is on the prevention of condensation water in order to protect the pipe against rust. In addition, the production of cold energy is generally more expensive than heat energy and therefore efficiency efforts are all the more important.

What are the motivation of the industry to carry out insulation?

On the one hand, the requirements of the labor inspectorate play a decisive role, since certain plant temperatures are set which must not be exceeded for safety reasons. On the other hand, potential energy savings are, of course, the motivation base for companies, to insulate pipes and to recover heat or cold effectively. Our experience shows that energy saving is the focus of the economic benefits and the fulfillment of the labor requirements is seen in many cases as a positive, necessary side effect.

Is monitoring of the measures carried out after implementation?

In most cases yes, the companies are very interested in the effectiveness of their measures. A well-known brick manufacturer, for example, has established a comprehensive monitoring system for its implemented energy efficiency measures. In many other cases, key indicators such as, for example, the amount of energy saving, are identified by the client together with the planner and the necessary measures are identified with us. A corresponding monitoring after implementation has to demonstrate the effectiveness of the measures and, if necessary, to show adaptation potential.

What is the role of the two subsidiaries of Duschk currently and in the future?

We have independent subsidiaries in Croatia and Romania that are self-sufficient. In these countries specialization has been made for fire protection, since there is still a lot of catching up to be made in this area. In the heat sector, district heating pipes in Romania are particularly noteworthy because they are either completely uninsulated or have only a gaps in insulation due to aluminum theft.

I expect steady growth for foreign branches. Austrian know-how is gladly accepted and has a high priority. This makes it possible to offer prices for high-quality services that are above average.

What is your employee structure, and what is the status of education and training?

At present, we have 135 employees in Austria, in the foreign branches it is 14. Our goal is a slow growth, adapted to the respective order situation.

Education and training play a major role in our company. Our employees regularly make use of product training in our industries because they are most closely aligned with the practical implementation and are very specifically adapted to the application. In the area of fire safety, trainings are being visited by test institutes or by the Association of Austrian Insulation Companies in order to be informed about the latest developments.

We attach great importance to the training of our apprentices, which represent the employees of the future for us.

How important are legal framework conditions in your field of activity and what developments do you expect in the future?

Apart from the already mentioned safety requirements of the labor inspectorate, the OIB guideline 6 plays a decisive role for thermal insulation, since essential requirements for insulation thicknesses are made. Further guidelines such as the newly published ÖNORM H 5155 also provide a very practical approach to insulation.

The thermal optimization of the building envelope plays a decisive role in the field of building renovation. From our point of view, it would be sensible to include increasingly the insulation of the domestic technology, since there is also great potential for savings. A possible implementation variant would be the greater involvement of the chimney sweeper in this context.

Where do you see the domestic insulation industry in an international comparison?

Austria is definitely in the upper third. As already mentioned above, Austrian quality is very much appreciated in Eastern Europe. Compared to other European countries, Austria can easily measure itself in the field of insulation.

Numerous international comparisons also show the good position of Austria in the field of education.
