Lignostone® - Laminated densified wood

Lignostone® is a laminated densified wood that consists of beech veneers (Fagus sylvatica), which are joined together with thermosetting synthetic resins under pressure and heat.

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.
