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.
