What is special about Lignostone® laminated densified wood?
For Lignostone® selected red beech veneers from highest quality are used. The peeled veneers used for Lignostone® are subject to stringent quality specifications and come from sustainable forest management.
Thanks to the excellent conditions in Western Europe for growing beech within a period of around 120 years, top grades of this product from logs of suitable length felled in the right locations offer extremely
good homogeneity that enables them to withstand the extremely high electric stresses. In addition to its electrical strengths, due to its intact capillaries with continuous load-bearing fibres this material offers unsurpassed mechanical strength values, which depend on the direction of lamination and the densification.
Applications
Due to its special material properties, Lignostone® is mainly used as insulation material in transformer construction and as thermal insulation for tank supports in LNG and LPG vessels.
Transformer construction

Lignostone® conserves valuable resources
We only purchase rotary cut veneers for manufacturing Lignostone® from suppliers who are certified in accordance with the regulations of the Forest Stewardship Council (FSC) FSC® product chain. The Forest Stewardship Council (FSC) based in Bonn is an international non-profit organisation that promotes the environmentally friendly and economically viable management of forests. For this purpose, it has developed standards based on which companies can be certified.
FSC® chain of custody certification ensures that the products of certified companies are made from responsibly sourced raw materials. For this purpose, companies have to streamline their processes and procedures in such a way that the traceability of the raw materials used is ensured and that statements can be made regarding the raw materials used in the product.
