Hybrid sandwich wall element


Concrete sandwich elements are the most common structural exterior wall solution in Nordic countries and widely used in middle European countries as well. The idea of Hybrid sandwich wall element is to make the common concrete sandwich wall element more environmental friendly and lighter by preplacing the interior load-bearing concrete layer with Kerto-Q LVL panel. Kerto-Q LVL panel’s compression strength in grain direction equals to the concrete C25’s compression strength resulting in the load-bearing capacity that doesn’t lose to the original concrete one. All connections and connectors are similar to the concrete solution’s ones. Hybrid sandwich element can be used with wooden as well as concrete floor structures both and doesn’t call for major changes in current processes on site.

Key benefit

Light weight, reduced carbon foot print, acting as a carbon sink, no major changes to current processes nor working methods on a construction site required, improved thermal performance of the wall structure
