Frequently Asked Questions
Cross-laminated timber panels are produced from kiln dried spruce/fir boards which are stacked at right angles and glued together over their entire surface. Depending on the purpose and static requirement, the plates are available in 3, 5, 7 or more board layers.
Gluing is carried out with PUR adhesive which is completely solvent and formaldehyde free and tested in accordance with DIN 68141 and other strict criteria by MPA Stuttgart and approved for the production of load-bearing timber construction elements and special construction methods in accordance with DIN 1052 and EN 301. Crosswise gluing at high pressure reduces the wood's expansion and shrinkage to an insignificant level.
KLH solid timber panels can be used for the superstructure of a building - large wall, floor and roof elements.
The production process produces zero-waste as all off-cuts, wood shavings and sawdust are manufactured into biomass pellets, and used to generate heat and power in the KLH Massivholz GmbH factories, and the excess is sold to local CHP plant.
No, KLH panels are solid cross-laminated timber building elements - industrially prefabricated panels which have a structural performance more akin to precast concrete panels.
Yes, KLH panels are available in 3 visual qualities - non visual quality, industrial visual quality and domestic quality. Domestic quality panels can be left exposed within the interior of a building, but should be treated with some kind of surface treatment (wax, oil) or spread of flame treatment (dependent on building regulations). Please see 'Surface Quality' document in the Downloads section of the Technical page for further information.
The panels are cut and processed in the KLH Massivholz GmbH factories, in Austria & Sweden, using state-of-the-art CNC technologies, resulting in excellent dimensional stability, both in overall panel size and for structural openings. Please see the 'CNC Processing' document in the Downloads section of the Technical page for further information.
