What is Osmose Naturewood preserved timber?
Osmose naturewood preserved timber 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 Naturewood preserved wood can be used for fencing, timber decking, landscaping timbers and construction timbers.

Osmose Naturewood products can be stained to match any outdoor colour scheme. Always follow manufacturer's recommendations.
