Characteristic of the golden-brown heartwood of the German oak that we use are the large pores and clearly visible medullary rays. The wood for a Formfeld wall panel comes from a single tree, resulting in a homogeneous color image. However, not all areas of the trunk are suitable, so we carefully select a high proportion of lamellae with standing annual rings by hand to obtain a calm grain pattern. Fine branches, convolutions, and inclusions are essential and distinctive authenticity features of the material. The wood surface is polished by hand in several steps and finished with a small amount of solvent-based wax oil. This protects the wood and preserves its color, similar to raw sawn timber. Over time, it will darken slightly.

For Natural Oak, the same requirements apply for the sorting and origin of the wood as for Light Oak. However, the surface is treated with natural wax oils that protect the wood and give it a typical saturated color tone. The texture of the grain is slightly more prominent than in the light version. Over time, this wood also darkens slightly.

Medium-density fiberboard, also known as MDF, is made from black-dyed wood fibers that are compressed into panels using binders under high pressure and heat. This manufacturing process involves using non-toxic, water-based pigments and low formaldehyde concentrations.
