With their excellent statical properties due to a structure made up of different plies glued together in alternating directions and their load transfer on all sides, KLH solid cross-laminated timber boards meet all requirements for high-quality, innovative and technically sophisticated structural timber engineering. The high load-bearing capacity in combination with the low self-weight allows a lean design of components even with large spans. Point-supported constructions or projections can be realised in a simple and economically reasonable manner. Numerous surveys and tests have shown that KLH solid cross-laminated timber boards are also perfectly suitable for the construction of stable buildings in earthquake zones.

The calculation of KLH solid cross-laminated timber boards is made under the aspect of flexibly connected profiles. The longitudinal plies are connected through shear-compliant cross plies so that as a rule, deflection as a result of transverse force (shear deformations of the cross plies) and the so-called roll shear can no longer be disregarded. Thus for the statistical calculation, KLH solid cross-laminated timber boards cannot be treated the same as glulam components.

Dimensioning and construction are either made according to DIN 1052:2008 taking into account the Allgemeine Bauaufsichtliche Zulassung [general technical approval] (Z-9.1-482) or according to EN 1995 (Euro Code 5) taking into account the European Technical Approval (ETA-06/0138). The statical verification for KLH solid cross-laminated timber boards must be made separately for every project and the locally applicable standards and regulations complied with.
