Responsibility - over generations.

Klinker and Thin Brick primarily consist of clay (sound minerals with a low grain size) and clay (mixture of sand, sound and silt). The geological origin of the sound or clay is decisive for the later color of the roasted clinker. Depending on the nature of the starting material, sand may be added during the preparation. In addition, clinker break is added during the preparation.

Tone and clay deposits are available to a large extent worldwide. Slateons are broken down in a depth of up to six meters in northern Germany. The sound deposits are therefore available regionally without long transport routes and with little technical effort. If the sound deposits are exhausted, the pit is renatured. This is done in close coordination with local authorities. The special focus is to achieve a high degree of biodiversity.

Klinker do not need flame retardant. What has already been burned at 1,200 ° C has no more flammable components. If Thin Brick are processed in connection with a mineral thermal insulation composite system, they are part of a sustainable fire protection concept.

Klinker and Thin Brick are burned at around 1,100 ° C, the pores are closed by the burning process. The result is a hard -burned stone that not only defies wind and weather, but also hardly absorbs moisture. To be more precise, the water absorption of Feldhaus products is usually between two and five percent. Together with a professionally executed joint, a clinker or Thin Brick facade forms a permanent elementary protective shield.

Politics and our society are increasingly relating to natural building materials. Manufacturers like Feldhaus Klinker have been carrying out their own control of technical product quality for many years. In addition, measurements are carried out by external laboratories. However, building certifications are becoming increasingly important in which the interaction of the various construction products and their influence on the environment are weighted and put into numbers. An important basis for this is an EPD (Environmental Product Declaration, or an environmental product declaration in German).

The EPD shows the environmental impact of a product throughout its life cycle.

The EPD is a list of environmental impact indicators of a certain building material, in this case of Klinker, Thin Brick and Pavers . This data is shown in a standardized manner. This makes it much easier to compare different materials. This makes it understandable which performance a product provides in the different phases of its life cycle. From raw material extraction to the manufacturing process, use to recycling.

A building material is ecologically sensible when it is of natural origin and protects the resources by being durable. A clinker facade lasts 100 years or more. We also know enough examples that brick buildings from antiquity have survived to this day.

Thin Brick since the early 1980s , who not sawn by the whole stone. We produce Thin Brick in the desired strength. This saves raw materials and energy. Since 2001 we have been producing angles, which are also made in the desired strength and shape. This overall package made of straps and angles is the most resource -saving method for a durable and low -maintenance clinker facade; For new construction and existing properties.

The construction and operation as well as the maintenance of real estate is responsible for a large part of the global CO2 burden. Time to change that. As a building material manufacturer and family -run Company , Feldhaus Klinker sees himself to counteract this. There are concrete measures and goals for this. The entire manufacturing and burning process is to be operated with regeneratively generated energy. With photovoltaics and wind energy, enough energy will be generated in the future to produce hydrogen for the burning process. A PV system with an output of 9 MW/P is currently being installed on the hall roofs at the Bad Laer location. At the present time (March 2023), 34,000 m² of solar panels with an output of a good 7 mW/p are already installed; This corresponds to the area of ​​well over 4.5 soccer fields. In addition, we are already able to add up to 30% hydrogen to the natural gas. With a variety of measures and large investments, Feldhaus Klinker contributes to getting closer to the goal of CO2-neutral real estate in the long term.
