KLH 3s 120 TT

KLH 3s 120 TT is a cross-laminated solid wood panel from KLH Massivholz GmbH, also known as KLH® - CLT. The panel has 3 layers and has a total thickness of 120mm. As a TT element, it is usually used as a wall in solid timber construction. 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.
