The type of treatment and application process will depend upon the end use of the timber. To help decide which treatment is most appropriate for your requirements, please use our treatment selector or contact us.

There are essentially two treatment processes; high pressure and low pressure. High pressure treatments are generally suited to high hazard situations such as outdoor wood and timber used in ground contact. Low pressure treatments are used in weather protected situations such as timber frame construction and building timbers above DPC.

PTG offers preservative treatments to cover all hazard classes and end uses:

Wolmanit CX - Advanced high pressure treatment for medium/high end use situations.

Wolmanit CX Brown - Pressure treated timber with built in brown colour for high hazard end uses.

Wolsit KD20 - Waterbased low pressure treatment for internal use.
