Sonar Flexible Wood

Wood and engineered wood are made flexible with a patented incision process. Complex incisions allow textile-like properties plus create transparency and sound absorbing properties unexpected from wood products.

Sonar’s regular incisions in the longitudinal direction create an interesting discontinuity on the surface with visible vertical and horizontal lines. Available in standard sheet sizes in seven wood types in natural or finished. The front and reverse sides look clearly distinct, so application areas are primarily ceiling and wall panels.

Based in Zürich, Switzerland, Dukta has its roots in wood bending experiments. During a training course led by Serge Lunin in 2007, Christian Kuhn had the idea to create a lounger made from curved wooden elements. Together they tested alternatives including steam bending and gluing layers together but found that certain arrangements of incisions gave the wood a great deal of flexibility. Now headed by the father and son team of Serge and Pablo Lunin, Dukta was founded in 2011 and works with licensed partners throughout the world.
