KLH 8ss 300 TL

KLH 8ss 300 TL is a cross-laminated solid wood panel from KLH Massivholz GmbH, also known as KLH® - CLT. The panel has 8 layers and has a total thickness of 300mm. As a TL element, it is usually used as a ceiling and roof panel in solid timber construction. To increase rigidity, the panel is manufactured with double edge layers. The crosswise arrangement of the longitudinal and transverse lamellas minimizes the swelling and shrinkage of the wood in the panel plane. At the same time, this increases the static load-bearing capacity and dimensional stability in the panel plane. Depending on the thickness and the presence of cladding, fire protection requirements of 30, 60, 90 and 120 minutes are met.

1) The shear modulus applies to the equivalent rectangular cross section and has been adapted accordingly (i.e. increased by a factor of 6/5), since the current FE programs generally do not allow any further specifications.
2) The shear modulus for the plate action specified here represents the less favourable value for the X and Y directions.
3) The shear modulus for the membrane action specified here represents the less favourable value for the X and Y directions.
