MycoWall: Organic Insulation for Future Timber Constructions

Popis výsledku v původním jazyce

The construction sector requires new insulation materials that reduce environmental impact and contribute to carbon storage. Conventional synthetic insulations are energy-intensive and difficult to recycle, whereas mycelium-based biocomposites (MBB) offer a sustainable bio-based alternative. Cultivated from lignocellulosic substrates bonded by fungal mycelium, they utilise low-value biomass and need no additional adhesive. This study investigates the application of MBB as an insulation material in timber buildings. Tests confirmed promising thermal performance, with a conductivity of 0.076 W/(m·K) achieved using recycled wood and mycelium of Ganoderma sp. fungi. A prototype wall panel was subsequently developed with heat transfer coefficient (U-value) 0.295 W/(m2·K). The construction concept combines MBB as the core insulation layer with cross-laminated timber (CLT) as the primary load-bearing system. Deciduous wood species (Quercus sp., Fagus sp.) were employed for complementary elements, treated with an innovative protective method. The external layer is designed as a ventilated façade made of oak profiles coated with a transparent finish containing metal oxide nanoparticles and UV stabilisation. The results demonstrate the potential of MBB to serve as an efficient, carbon-storing insulation material and to enhance the sustainability of building envelopes in modern timber architecture.
