| Abstract: | Environmental considerations have become increasingly important in the construction industry, driving the search for more sustainable alternatives to conventional building materials and solutions. One resource-intensive material used for structural decoupling is the impact-resilient layer, which, when installed in floating floors, is crucial for achieving the required insulation ratings. This study presents a methodology for developing an impact-resilient layer. The approach defines the key performance parameters of a floating floor and follows an experimental development approach based on prototyping. Prototypes are iteratively improved, with the first generation providing proof of concept and evolving into a final large-scale prototype that validates the impact insulation performance. To validate the approach, it is applied to the development of a wood-based resilient layer as a case study. The introduced resilient layer is highly sustainable and follows design for disassembly principles, while technically relying on a novel elastic response mechanism based on the flexural deformation of wooden strips. Over three generations of prototypes, the design evolved systematically, considering different geometric configurations, wood species, and wood-cork composites to manufacture the strips. The experimental evaluation focused on load-bearing capacity, dynamic stiffness, and damping ratio, also accounting for the inherent variabil ity of wood and wood moisture content as experimental parameters. A viable design was achieved and showed competitive impact sound insulation compared to established reference solutions. These results demonstrate that the proposed development approach can be successfully applied in practice and that a wood-based resilient layer can be a viable alternative to conventional market solutions. |
