Treatment Process

The TRU-CORE® Process (Patented and Patents Pending) can be used to fully penetrate many different types of wood products. This treatment process can also be used to penetrate heartwood, “hard to treat” wood species, and the multiple glue lines of engineered wood products.

The TRU-CORE® Process can be used to treat wood while maintaining wood product properties and the low water uptakes during treatment assist with meeting end product wood product moisture specifications.

The TRU-CORE® Process provides batch treatment options..

Additional Information:

Australian-Standards Compliant:
Timbertreat A Azole Insecticide/Fungicide Preservative is a water-based formulation of propiconazole and tebuconazole (1:1) plus permethrin. A vacuum pressure process is used to treat timber to meet the AS1604, H3 treatment standard.

For H3 treated hardwood, the AS Standard requires complete penetration of the sapwood and a portion of the heartwood to be penetrated and treated to achieve a specified chemical retention. The heartwood penetration requirement depends on the natural durability rating for the timber species, timber piece dimensions and proportion/location of any heartwood in the timber piece cross-section.

Refer to AS1604, H3 for more information on the penetration requirements.
