Lignotrend Timber Systems

Lignotrend involves panel elements created using several timber layers with the grain direction perpendicular to each neighbouring layer. The layers are cleverly arranged achieving hollow wall and floor elements. Several variants, most of which have a cross-laminated inner layer with varying presentation faces. There are glue laminated ribs of various depths to which can be fixed an outer layer of choice. In some variants, there are stabilising planks accross the ribs. One way system.


Lignotrend elements are dimensionally stable due to the glued layers perpendicular to each other. Lignotrend floors are lightweight (relative to competing massive timber systems), with high structural capability. The system is most likley best suited to multi-storey applications.

  • Doesn't use as much timber as competing massive systems
  • Hollow construction makes for easy running of services (in the direction of the span only)


Adhesive offgassing may need to be addressed; May need a better grade of plantation softwood if adapted locally; Manufacturing process looks complex. The cost of this system may be an issue in single family dwellings where acoustic performance etc. is less of a criteria.


Would need sound deadening material if used as floor planks in multi level construction and/or use of with a concrete screed; Creep issues would need to be resolved in multi-storey situations; local detailing for termite resistance would need to be developed.
