Treated Timber

Pressure treated timber is timber which has been impregnated with Tanalith® E wood preservative under controlled conditions in a vacuum pressure timber impregnation plant.

Tanalith® E is a waterbased wood preservative that contains copper and organic biocides (triazoles). When impregnated into the timber the preservative components bond with the wood structure and cannot easily be removed.

Tanalith® E pressure treated timber gives long term protection against fungal and insect attack, including termites, for both in and out of ground contact, interior and exterior applications.

Naturally green in colour. Upon external exposure, the green colour slowly weathers to a warm, honey brown and in the longer term becomes a natural silver grey. See our treatment info for cut-end re-treatment notes.

Lengths from 2.4m (8ft) up to 6.1m (20ft) available for cutting and delivery. Need carcassing cut to length? Use our timber cutting service — and see the FAQ for returns on cut timber.
