| Abstract Scope |
Natural fiber-based construction materials have gained relevance due to their low density, renewable origin, and potential contribution to thermal and acoustic comfort in buildings. This study reviews the use of lignocellulosic fibers and residues in panels, cementitious composites, lightweight components, and building envelope materials, focusing on thermal insulation and sound absorption performance. Literature involving coconut, sisal, jute, bamboo, piassava, agricultural residues, and other plant-based fibers was analyzed. The reviewed studies indicate that the porous structure, low thermal conductivity, and internal fiber morphology of natural materials can contribute to reduced heat transfer and improved acoustic damping. These properties are particularly attractive for non-structural panels, partitions, ceilings, and prefabricated components. However, moisture sensitivity, biological degradation, fire behavior, and dimensional instability remain important challenges. Overall, natural fiber-based materials represent promising alternatives for improving building performance while reducing environmental impacts and supporting circular use of renewable resources. |
