Hybrid construction offers construction companies more sustainable buildings without changing the current way of construction. Metsä Wood and its partners have designed a hybrid sandwich wall element which will renew offsite construction. The innovation combines concrete with Kerto® LVL (laminated veneer lumber). The first construction project to use the elements is Metsä Fibre’s Rauma sawmill.
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 construction helps to increase the share of wood to build more sustainable buildings efficiently. This joint development is our effort to support the construction industry,” says Jussi Björman, Director at Metsä Wood. He is responsible for business development in construction.
Björman gives examples: the connections between the wall elements are similar and so are the lifting loops compared to the ones used in concrete elements.
