© Accumulation wall in the TFH system

The subject of the project at Tadeks Fertig Haus is the implementation of an innovative product (in the process of obtaining a patent), developed as a result of R+D work with the participation of product institutes. It is a prefabricated external wall made in the timber frame technology, containing a special layer made of dried clay brickwork and clay plaster with a sunken heating system applied to it. In total, the clay accumulation layer is 85mm thick. This provides additional, much greater than previously achieved accumulation of heat and moisture, features desirable from the point of view of energy-efficient construction. Our production line has been adapted to streamline, optimize the planned technological process and enable the production of heavy prefabricated wooden elements covered with a layer of clay. As part of the project, solutions in the form of process, product and non-technological innovation will be implemented through the purchase of fixed assets.

The numerous advantages of raw clay clearly speak in favor of popularizing the use of this material in contemporary, sustainable construction, in addition, when used in our highly energy-efficient wooden structure, we finally get a product that ensures the diffusion openness of the partition and, in addition, additional advantages:

Clay regulates air humidity – it can absorb moisture quite quickly and release it. In this way, it affects a healthy indoor climate.
Clay stores heat – just like other heavy building materials. In this way, it contributes to a better indoor climate and, with the passive use of the sun, also to significant energy savings.
Clay saves energy and reduces environmental pollution – unlike many other building materials (e.g. fired brick or concrete), very little energy is required to prepare and process clay. Thus, the use of clay in construction causes negligible environmental pollution.
Clay can be reused – unfired, raw clay can be successfully reused. It does not litter the environment as debris. All you need to do is crush it and wet it with water to obtain a full-fledged building material.
Clay is economical as a building material – it allows you to reduce transport costs, because it can often be extracted directly on the construction site when digging foundations or bought in a nearby brickyard.
Clay has properties that absorb harmful substances – primarily sulfur and phosphorus compounds. It also gives protection against high-frequency radiation.
