Hybrid construction offers construction companies more sustainable buildings without changing the current way of construction. Metsä Wood and its partners designed a hybrid sandwich wall element which will renew offsite construction. The innovation combines concrete with Kerto® LVL (laminated veneer lumber).

The need for more sustainable solutions is acute, because construction causes 30% of all CO2 emissions. Combining concrete and Kerto LVL, the hybrid sandwich wall elements offer an easy way to replace typical concrete sandwich elements, the popular wall element in residential multi-storey buildings in Nordic countries.

Most importantly, the innovation guarantees efficient construction.

The hybrid sandwich wall element helps to increase the share of wood to build more sustainable buildings efficiently.

The connections between the wall elements are similar and so are the lifting loops compared to the ones used in concrete elements.

Metsä Wood partnered with JM-Rakenne Oy, Peikko Oy, and Arkta-Reponen Oy to design the optimal hybrid sandwich wall element, which can be used in residential, office or industrial multi-storey buildings.

Structural layers

  • Exterior concrete layer 70mm
  • Insulation 220mm + layer connectors
  • Kerto-Q LVL panel (grain direction vertical)

Key benefits

  • Lighweight
  • Reduced carbon footprint
  • Acting as a carbon sink
  • No major changes to current processes or working methods on a construction site required
