TANALITH® E is the latest generation wood preservative. Already established in markets throughout the world, TANALITH® E treated timber provides a proven alternative to traditional CCA treated timber for the timber trade and for the general public.
TANALITH® E preservative has a unique copper and organic biocide (triazole) formulation allowing TANALITH® E treated timber to be used where special environmental concerns or restrictions exist, as well as the everyday construction, landscaping and engineering applications for which treated timber is renowned, e.g. children’s play areas.
1. The Tanalising process involves placing the timber within the treatment cylinder and creating an initial vacuum within the timber cells.
2. The cylinder is then flooded under vacuum with the preservative treatment
3. Hydraulic pressure is then applied forcing the preservative deep into the timber cells
4. After a pre-determined period of pressure depending on the species of timber being treated and its eventual use, the treatment solution is pumped back into storage and a final vacuum extracts any excess treatment solution from the timber
5. Low pressure inside the timber draws in surface solution when vented to the atmosphere and the treated timber is left for a specified period for fixation of preservative to occur
Wood and wood-based material is exposed to varying levels of danger during its application.
The risk of wood infestation by biotic pests such as wood decaying fungi and wood decaying insects grows with the effects of exposure to weather conditions,
which affect the material.
|Hazard/use classes of wood exposure
||Examples of wood applications
||The wood is under shelter, fully protected against weather conditions, not exposed to humidity (max. wood humidity of 20%)
||floorboards, battens, joinery and cabinet making timber
||The wood is under shelter, fully protected against weather conditions, ambient humidity can lead to occasional increases in wood humidity (wood humidity occasionally > 20%)
||construction timber, cladding, roof timber with increased risk of water vapour condensation
||The wood is in the exterior above the ground level, exposed to repeated humidity increases (wood humidity often > 20%)
||exterior timber, soffits, cladding structures, roof shingles, railings, fencing plates
||The wood is in direct contact with the ground or fresh water
||electric posts, noise barriers, wooden foundations, children’s playgrounds, pillars, bridge structures
||The wood is permanently exposed to the effects of sea water
||sea borers, fungi
||piers, moles, wharfs, ships´ hulls
