High Pressure Timber Treatments
Our timbers are pressure treated which means they have been impregnated with Tanalith® E wood preservative under rigidly controlled conditions in our own on-site vacuum pressure timber impregnation plant. The resulting Tanalised® E pressure treated timber has a natural pale green colouration.
Fencing and landscaping timbers can also be treated with a built-in brown colouration, Tanatone®, if required.
The Use Class
The level of preservative treatment is varied according to the Use Class situation that the timber is exposed to during its life. Generally, a greater degree of protection is required as the Use Class increases. Tanalised® E treated timber is suitable for all the Use Classes with Tanatone® treated timber being more widely used for Classes 3.2 and 4.
