Why Boral Hardwood Decking?
- Boral Decking is manufactured from Australian hardwood species that have proven durability in Australian conditions.
- Unlike many imported products, Boral decking has a Quality Assurance system that ensures strict tolerances and drying procedures to produce a high quality product.
- Boral Timber decking is AFS Chain of Custody certified providing peace of mind that Boral’s decking is sourced from sustainably managed and legal forestry.
- The same timber species can be used for internal flooring and outdoor decking, to provide a seamless transition from inside to outside, expanding living areas or to create an outdoor room.
- Blackbutt and Spotted Gum have a natural fire resistance. Their fire retarding properties make them suitable for use in many bushfire prone areas under Australian Standard AS3959.
- Australian hardwoods can easily be finished with a clear decking oil or stain. Alternatively the timber can be left to weather to turn an attractive silver grey. After timber has weathered it can be restored to its original colour by resanding and coating.
- Building codes and Australian Standards should be adhered to when building with Boral Decking.
