SupaTimber uses a fully-dissolved copper-based wood preservative solutions for exterior wood products. Formulations provide long-term protection from fungal decay and termite attack for a wide variety of commercial, industrial and agricultural construction projects including; above-ground, ground contact, fresh-water immersion, and salt-water splash and immersion applications.
SupaTimber CCA uses recycled copper, reducing the carbon footprint of its manufacture. Copper has been used for centuries to control fungi, and is highly effective against most forms of fungi that feed on wood. The fully-dissolved copper is very effective in penetrating the cells in the wood fiber during the pressure-treatment process, providing for optimum long-term protection.
In the US and other countries, CCA is registered for use on: lumber, timbers, landscape ties, fence posts, building and utility poles, land, freshwater and marine pilings, sea walls, and other wood structures.
SupaTimber treatments lend a distinctive green tint to the timber, although an additional color pigment; DesignWood can be introduced during the treatment process to stain the wood in shades of brown and green.
