Vulcan Decking is created from thermally modified New Zealand plantation timber and then treated with an organic preservative system that includes a water repellent for superior durability.

The thermal modification process means Vulcan Decking has enhanced stability, reduced resin content and a beautiful homogeneous brown colour. 

Quality: premium-grade graded to the reeded face with mainly clear sections, but with some defects including knots and resin pockets (allowed up to ⅓ of board width). Reverse face with defects permitted according to standard grade. 

Substrate colour: chocolate brown (timber will weather to grey unless a pigmented coating is applied and maintained).  

Durability: thermally modified to INTENZ Thermowood 230° schedule. Treated with OPX azole-based preservation system. Durability to class 1 (EN350) and H3 (AS1604). Suitable for use as class 3 (EN335). Resistant to attack from wood-boring insects and termites.  

Bushfire rating: BAL 12.5 and 19; all AS 3959 required applications.
