Séparateur Présentation

The autoclave treatment is used to protect the wood from external aggressions.
The wood is exposed under certain conditions of use, such as a terrace or cladding. This treatment increases the durability of the wood for up to several decades.

The autoclave is a large pressurized tunnel where a preservative is injected. An air vacuum cycle is established in order to remove a remainder of water and to open the fibers of the wood, the tunnel is then filled by depression and the wood begins to absorb, once the equipment is filled, a booster takes the relay to increase the pressure between 11 and 12 bars in order to inject the maximum amount of preservative.

A final vacuum cycle is established to remove the remaining product.

A period of 7 to 15 days depending on the season is recommended to stabilize the product and wipe the wood.
