Dutch clay bricks are made of unbaked clay soil pressed into uniform building blocks. These blocks are suitable for use in load-bearing and non-bearing walls, accumulating walls and heat finnovens.

Additionally, the earth-based material properties of these bricks give them the ability to regulate interior building climates. A mud building, for example, acts like a third skin to the user and has a warm, relaxing atmosphere. Loam likewise naturally regulates interior environments. Because these clay bricks are not fired, their unique moisturizing and heat-accumulating properties are maintained. Due to the high mass of limestone, a mud wall can retain and give off heat well so that temperature fluctuations are effectively minimized. Furthermore, clay emits no harmful gases and substances to the indoor environment and also has a neutralizing effect on pollutants and cigarette smoke, for example.

The constant relative humidity of about 50% in a mud or loam indoor prevents the formation of mould. Therefore, especially for people with respiratory problems, such environments provide a ‘breath of fresh air.’

The composition of dutch clay bricks is stone clay (clay, silt, sand), usually present in natural form. The shape is rectangular with a standard size of 295mm x 140mm x 90mm and a weight of 7.5kg per stone. 2200kg per m³.
