Timber treatment

Osmose Naturewood

Naturewood preserved wood is the name given to timber that has been preserved with an Osmose preservative system, which is based on copper and an organic co-biocide (Alkaline Copper Quaternary). Osmose Inc is based near Atlanta, Georgia USA. The company was established in 1932, and serves many pressure-treated wood markets all over the world. Alkaline Copper Quaternary systems have provided proven performance for almost a decade in locations throughout Europe, North America, Australia and Japan. Osmose Naturewood preserved wood can be used for fencing, timber decking, landscaping timbers and construction timbers.

Osmose Naturewood preserved wood has been protected using a modern copper-based preservative system. Copper, a naturally occurring mineral, is an effective and widely used fungicide. The preservation process prevents decay and extends the life of the timber.

Osmose Naturewood products will initially have a green appearance that highlights the natural variations of the wood. This will weather to an attractive natural honey brown colour before finally fading to a driftwood grey after long term exposure to the sun. Osmose Naturewood products can be painted or stained to match any outdoor colour scheme.

The preservation process:

  • The timber is transferred into the treatment vessel.
  • A vacuum pulls the air out of the vessel.
  • Osmose Naturewood preservative fills the vessel.
  • The vessel is pressurised forcing the preservative into the timber.
  • The preservative is removed and a final vacuum is applied removing excess.
  • The timber has now been treated with Osmose Naturewood.
