Innovative thermal modification processes make it possible to improve the sustainability and dimension stability of softwood and hardwood.

Thus arises durable wood with a sustainability class I/II, which is a good alternative for impregnated wood and tropical hardwood.

Thermo wood is insensitive for wood rot.

Wood exists for almost half from cellulose fibres, for 25 to 35% from lignin and for 20% from hemicellulose. Particularly hemicelluloses are able to absorb water, as a result of which the wood swells up. Moreover moulds are able to demolish these hemicelluloses are and lignin’s and feed themselves whit that, what eventually leads to wood rot.

The modification processes are environment-friendly because they have been based on a response of substances which are by nature in the wood. The wood is heated to a temperature between 200 and 250°C during the preservation process. The cellulose structure remains intact but the hemicelluloses and lignin are demolished. In short, the sugars in the wood are demolished what reduces the growth of moulds. There demolition products form a type resin, which fills up the space between the fibres. Furthermore the protecting components spread themselves in the wood, as a result of which the whole piece of wood is strongly protected.

The heat gives the wood a new and warm brown color.
