klinkern

Klinkern is a building material traditionally made from clay that is fired at very high temperatures. This firing process causes the clay to vitrify, meaning it becomes glass-like and extremely hard. The result is a dense, durable, and frost-resistant material. Klinkern are commonly used for exterior claddings of buildings, as paving stones, and for decorative elements. They are known for their longevity and resistance to weathering.

The production of klinkern involves selecting specific types of clay, often rich in silica and iron. These clays are shaped into bricks or tiles and then fired in kilns at temperatures typically exceeding 1100 degrees Celsius. The intense heat and prolonged firing time are crucial for achieving the characteristic hardness and low porosity of klinkern. The color of klinkern can vary depending on the clay composition and firing conditions, ranging from deep reds and browns to yellows and grays.

Due to their durability and aesthetic appeal, klinkern have been used in construction for centuries. They offer a natural and robust alternative to other facade materials. Their low water absorption makes them particularly suitable for applications exposed to harsh weather conditions, such as rain, frost, and thawing cycles. Klinkern are also valued for their low maintenance requirements.
