Our Tanalised Sawn Timber is protected from Fungal and insect attacks to maximise lifespan. Tanalith E pressure treated timber is a timber that has been impregnated with Tanalith E wood preservative under controlled conditions in a vacuum pressure timber impregnation plant.

Tanalith E is a water-based wood preservative that contains copper and proven organic biocides. When impregnated with the timber the preservative components bond with the wood structure and cannot easily be removed. Tanalith E pressure-treated timber has long-term protection against fungal and insect attacks, for both in and out-of-ground contact, interior and exterior applications when treated to the correct end-use specification. Tanalith E pressure-treated timber has an initial natural green colouration.

With external exposure the green colour slowly weathers to a honey brown and in the longer term becomes a silver grey. This weathering process does not indicate any loss of preservative protection.
