Reducing the environmental impact of construction, one of the most polluting industrial sectors, is essential to combat the climate crisis and, for this purpose, we need to start from natural, recyclable and sustainable materials. In this research, panels fabricated with jute and wool fibers, recycled respectively from jute bags used (end-life) for packaging coffee beans and from old (end-life) mattresses, and panels fabricated with a loofah-clay mix were realized and characterized. Comparative analyses were carried out considering in particular insulating characteristics in terms of thermal conductivity and acoustic performance.

The thermal conductivity values obtained for jute fibers panels are always included in the upper range of results available for wool fiber with similar density (about 20 kg/m³), but always the lower range of results available for jute-polyester-polypropylene sandwich composite panels. The results obtained for products with clay are obviously strongly dependent on the percentage of binder (clay) in the mix, the increase of which leads to an increase in density, negatively influencing the results obtained. Also, if from the acoustic point of view, it is not possible to add the contribution of the single layers, the noise insulation calculated for the different materials under test has shown for the single layer the good property to break down the noise.

作为污染最严重的工业部门之一，减少建筑对环境的影响对于应对气候危机至关重要，为此，我们需要从天然、可回收和可持续的材料着手。在这项研究中，分别从用于包装咖啡豆的（报废）黄麻袋和旧（报废）床垫中回收黄麻和羊毛纤维制成的面板，以及用丝瓜络-粘土混合物制成的面板，并对其进行了表征.  进行了比较分析，特别是考虑了导热性和声学性能方面的绝缘特性 。

黄麻纤维面板的导热系数值始终包含在具有相似密度（约 20 kg/m 3 ）的羊毛纤维的可用结果范围上限内，但黄麻-聚酯-聚丙烯夹层复合材料始终包含在可用结果范围的下限^范围内面板。含有粘土的产品所获得的结果显然在很大程度上取决于混合物中粘合剂（粘土）的百分比，其增加会导致密度增加，从而对所获得的结果产生负面影响。此外，如果从声学的角度来看，不可能添加单层的贡献，则为不同的被测材料计算的隔音性能表明单层具有良好的隔音性能。
