The material

The durability is in the treatment.

The durability belongs to the treatment, not the timber — which is why the Use Class matters more here than the species does.

A copper-based preservative is forced into the timber under vacuum and pressure, leaving the characteristic green or brown tint. Penetration follows the permeable sapwood, so sections with a high heartwood content take up less and are specified accordingly.

Fencing, gates and posts, decking and sub-frames, raised beds and landscaping, sheds and outbuildings, and general external carcassing. Every cut or drilled surface exposes untreated timber and must be brushed with an end-grain preservative.
