KLH® solid wood panel

KLH® solid wood panels are offered in three standard qualities. Special surfaces and special bodies are possible on request and depending on the availability of the slats and technical feasibility.

By using double layers, the longitudinal or transverse stiffness of the board can be increased in a targeted manner. By changing the panel structure, the fire resistance can be increased on a project-by-project basis.
