Novawood
Novawood is thermally modified timber (thermowood) which increases the stability and durability of wood.
Naturally, wood is composed of 50% cellulose, 23% hemicellulose, 20% lignin, and 7% other organic compounds, called extractives. Heat treatment removes resin, other extractives and their attached OH (Hydroxil) groups from the wood.
This process reduces water absorption of wood, therefore increasing decay resistance while decreasing swelling and shrinking. Another factor that contributes to the high durability of wood is the crystallization of cellulose. The change in hemicellulose increases the durability. Hemicellulose is separated into furfural and carboxylic acid. Caramelization of lignin, caused by heat, results in a darker color.
This results in an exterior (and interior) product that is 100% natural, ecological, durable, stable, homogeneous, safe, isolated, and resistant to insects.
