CROSSL AMINATED TIMBER CROS S - LAMINATED TIMBER Cross-laminated timber (German abbreviation: KLH) is produced from layers of spruce wood that are arranged crosswise on top of each other and glued to each other with a pressing power of 6 N/mm² to form large-sized solid wood elements. The crosswise arrangement of the longitudinal and transverse layers reduces the swelling and shrinkage of the wood in the plane of the panel to an insignificant minimum and considerably increases the static load-carrying capacity and dimensional stability. In order to rule out any damage caused by pests, fungi or...

Non-visible quality is only recommended for non-visible construction components, planked from both sides. The lamellae are sorted according to strength classes. Most of them are rated as C 24 strength class timber, use according to approval. The longitudinal layers are fingerjointed. INDUSTRIAL VISIBLE QUALIT Y (IVQ) As a standard, industrial visible quality is executed in a one-sided manner. A double-sided version of this surface is available on request. Industrial visible quality is suitable for industrial surfaces, but not for visible surfaces in living areas. For industrial visible surfaces,...
