Surface

In the Surface Area, wood, wood-based as well as other material surfaces (composites, mineral substrates) are provided with properties which they naturally do not have or which the manufacturing process does not provide them with, but which they require for their practical application – be it as a protective feature, as a decorative surface or for obtaining special functionalities. Solutions are being developed in the following areas; services are being provided applying appropriate technical equipment:
