H3 Clear (Azole with Permethrin) wood treatment process is capable of protecting timber from borers & termite attacks and rot (moderate decay) in outside above ground applications (Should be at least 300mm above ground including vegetation and water sources). The treated timber is colourless for appearance grade.

H3 Clear treated timber is penetrated through sapwood and heartwood and does not contain harmful chemicals such as solvent. It comes with a 25 year guarantee from insect attacks and/or fungal decay (see warranty details).

Your appearance grade timber e.g. decking, screening, cladding, or windows will be treated with the utmost care. We do not stamp these with timber codes but instead we use timber tags.
