In collaboration with the University of Kassel, researchers at the Fraunhofer WKI have therefore developed a realistic rapid-aging procedure that can be used, in particular, by small and medium-sized enterprises (SMEs). The accelerated testing significantly reduces development times and enables a more realistic assessment of material performance throughout the life cycle.

At LIGNA 2025, researchers from the Fraunhofer WKI will be presenting a new type of curtain-wall element as a sustainable solution for the renovation and modernization of buildings. Not only durable raw materials such as robinia wood are thereby utilized: Less durable wood species such as spruce, poplar and kiri have also been optimized using bio-based coatings. 

At LIGNA 2025, the Fraunhofer WKI and the Technische Universität Braunschweig will be presenting groundbreaking approaches for a resource-conserving and climate-friendly construction industry: activities in research and teaching around the topic of building with wood and other renewable raw materials: from natural-fiber insulation materials, through timber-concrete composite systems, and on to recycling management.

Researchers from the Fraunhofer WKI will be demonstrating that bio-based flame-retardant coatings can provide durable fire protection for wooden furniture. A honeycomb-shaped shelf unit with the novel flame-retardant coating, as well as other exhibits, can be seen at LIGNA 2025, Hall 26 from the 26^th to the 30^th of May 2025 in Hanover.
