Mycelium-based composites (MBCs) have attracted research enthusiasm all over the world;" they are developed by growing mycelium over lignocellulosic residues, and these MBCs are low in density, porous, and biodegradable in nature. Recent studies underscore their potential in thermal and acoustic applications where these intrinsic properties are beneficial. In the context of burgeoning literature, this review singularly offers a comprehensive engineering assessment that simultaneously addresses thermal and acoustic design strategies for mycelium-based composites. Main recommendations are tailoring pore structure, hybridizing with complementary materials such as aerogels and phase change materials, and designing multi-layered systems to optimize sound absorption and thermal conductivity. However, limitations in the mechanical properties, water resistance, scalability, and the absence of consistent testing standards pose a challenge in benchmarking MBCs against conventional materials. Future studies must emphasize the enhancement of material uniformity, multi-functionality, and standard evaluation assessment for facilitating their wider utilization in the construction industry. Overall, MBCs drive the sustainable economy for an energy efficient and healthier in-built environment in building and construction."Mycelium-based compositesThermal insulationThermal conductivityAcoustic insulationSustainabilityArticulohttps://doi.org/10.1016/j.compositesb.2026.113470
