Mycelium Composites In Sustainable Building Applications: A Comprehensive Review Of Acoustic And Thermal Insulation Properties

Abstract

The end goal of any interior space is to provide the ultimate human comfort. This is achieved through various factors such as thermal regulation, acoustics and general environmental well-being. Conventional insulation and acoustics materials are effective but not eco-friendly due to limited biodegradability. This review paper explores the potential of lightweight mycelium-based composites (MBC) as a promising alternative for conventional acoustic and insulation panels. Mycelium is the fungal network on agricultural waste of mushrooms. Many comparative studies suggest that the thermal and acoustic properties of MBCs are comparable to conventional materials, but its lower durability remains a challenge. This paper integrates the current research about performance, materials, processes, and limitations of mycelium as well as its potential to contribute to sustainable construction and circular economy.
