Obernkirchener Sandstein® facades are durable, resistant to environmental impacts and require only a small amount of optical care. These attributes are demonstrated by the facades that make up the long history of Obernkirchener Sandstein®. Even after 1000 years, most of the detailed stone carvings remain practically unchanged - without maintenance, chemicals, or constructive protection. In addition to its durability, the use of Obernkirchener Sandstein® also adds up in terms of economic efficiency calculations, particularly in consideration of the follow-on costs of a building.
As a practically ecologically neutral building material, Obernkirchener Sandstein® requires no technical maintenance. It is economical, durable and resistant to frost and environmental impacts. It has a compact, fine-grained surface combined with outstanding technical values - the same dry density as normal concrete, with compressive strength four times higher than a C20/25. Obernkirchener Sandstein® is a building material that exudes tradition, warmth and elegance, as well as purist coolness and practicality.
