Proposals for solutions in accordance with German standard DIN 4108 Teil 7 What does real life look like? What can actually be solved? Challenges, interface issues between the different trades and crafts, and possible suggestions for solutions.
The industry-wide educational and training center of the Baden-Württemberg Carpentry Association in Biberach an der Riss has been working on the complex issue of building airtightness for many years, not only with a focus on timber construction, but also concentrating on the rehabilitation of buildings of various other methods of construction.
In the practical and hands-on training of apprentices, this topic had even been included in the curriculum as a mandatory subject more than 13 years ago. Over the course of the years, it has been adjusted to the requirements of the German standard DIN 4108-7 and the German Energy Savings Regulation (EnEV).
The title “There is a draught, so what?” paraphrases what many building experts unfortunately still think of this topic.
The presentation shows how our educational and training center teaches the requirements for the thermal building envelope (airtight layer) in basic and advanced education and training for trained and skilled workers and master craftsmen in the field of carpentry.
The German standard DIN 4108-7 serves as a platform for the implementation of specific standard details (support). In addition, at the construction sites, the carpenters are exposed to a wide range of influences. By way of looking at how the airtight layer can be laid out and how the corresponding insulation materials are used and implemented, the presentation shows details and the respective possibilities for solutions.
Some of the greatest challenges are issues in the interplay between the different crafts and trades involved in construction, as well as the expertise of these contractors. Even new buildings tend to be faulty to some extent, which can be detected during measurements. This is where the planners must optimally coordinate the processes for the different types of contractors involved. However, it is also up to the workers to recognize connections and to act accordingly. During quality control, flaws must be exposed without sparing anyone.
The master craftsmen serving as instructors and trainers in Biberach are not only very concerned with sensitizing the apprentices to this topic, but also with including the latest findings in further and advanced education and training courses. In the workshops, theoretical as well as practical work is explained and implemented using different models. The presentation discusses approaches to education and training for new and existing buildings.
