“Multi-material model Wall I Ceiling I Roof”

The highlight this year is the “Multi-material model Wall I Ceiling I Roof”. From the floor, through the walls, and on to the roof, the exhibit combines eight innovations for the future of construction.

1. Ceiling system modules made from modular, prefabricated small panels comprised of wooden or wood-concrete elements for a mosaic-style coffered ceiling
2. Wall made from thermal-insulation bricks filled with novel insulating materials on the basis of beech-wood fibers
3. Interior-wall cladding consisting of a selection of OSB, plywood and particle board made from various types of wood, manufactured in part with formaldehyde-free bio-adhesives
4. Ceiling beams made from laminated veneer lumber as a demonstrator for the utilization of the climate-resilient wood species Scots pine
5. Glued laminated timber beams for the ceiling construction made from the “future-wood” pine
6. Flax-wood hybrid system as ceiling beams
7. Wooden cladding which has been treated with extremely UV- and weather-resistant transparent varnish for outdoor use
8. Wall made from robinia veneer - the species of wood with the highest durability class of European wood species: Usable in exterior applications without further wood-protection measures

The Fraunhofer WKI develops application possibilities for the raw material wood for various industrial sectors. Examples for the mobility industry include a multicopter with veneered laminated materials, and a wooden crash barrier for use in road traffic. For the watersports industry, researchers will be presenting a stand-up paddleboard made from a lightweight-construction sandwich element which incorporates renewable raw materials. For the construction sector, the Fraunhofer WKI is presenting a bicycle and pedestrian bridge made from sustainable laminated materials. Also on display is a mechanical-climatic rapid-aging process for structural wood-based materials. 

The Fraunhofer WKI will be presenting industry-oriented fire-protection solutions for wood and wood-based materials as well as novel bio-composites. Furthermore, the researchers will be demonstrating their expertise in the field of the testing of adhesives and bonded components for load-bearing and non-load-bearing timber-construction applications.

The Fraunhofer WKI will be presenting its innovations in Hall 26, Stand B 78. Co-exhibitor is the International Association for Technical Issues Related to Wood (iVTH).

LIGNA is the world's leading trade fair for tools, machinery and equipment for woodworking and wood processing and will be held in Hanover from 15^th to 19^th May 2023.
