Composition of our house walls.
The walls to our temporary house are composed of an exterior of reclaimed wood that has been preserved using yakisugi. Mycelium is used as installation and on the inner walls of the house is layer of chitosan.
We utilised reclaimed wood as a renewable resource that reduces the need for new products and landfill waste. The wood will undergo yakisugi process. Yakisugi was first used in the 18th Century Japan as a wood preservation technique by charring the surface of the wood with fire.
The process involves charring the surface of the wood, then left to cool and cleaned of its debris, it is finally finished with a varnish seal.
The wood becomes very low maintenance and naturally durable from moisture damage, fire, insects and rot. There are no chemicals used in the process of preservation allowing it to be a environmentally friendly process without contributing to pollution. When the lifespan of the wood has been reached, it can be disposed or recycled without harming the environment.
Mycelium has great thermal conductivity, acoustic performances and its fire retardant properties, and it makes for the greenest insulation option available. Mycelium insulation panels are also cost competitive with foam insulations and requires less energy to produce. Growing mycelium with in-between yakisugi and chitosan walls would allow the walls to adhere to one another. This removes the requirement of toxic glues used for bonding. To finish the process of producing mycelium panels, they are dried and heated. This is where I get confused and need to do more research on. How can you dry and heat the mycelium panels when they are sandwiched between wood and chitosan? Would we really need to use glue? Thats what I need to research. Ecofriendly glue?
