Iron ASH

/ The Upland Farm

H3 treated Victorian ash – as beautiful as it is durable and guaranteed to perform

  • / H3 Durable
  • / Straight line edged
  • / 25 year guarantee
  • / Continuous flow of design

Treated to H3 classification (per AS1604 Specification for Preservative Treatment), IronAsh can be used externally in partnership with GoodWood Victorian Ash to allow continuous flow of timber design from inside to out.

IronAsh is a great choice to finish the project. It can be easily cut, stained and painted on site. The IronAsh range offers an affordable timber choice that is stable  and readily available.

Sustainability

Sustainable timber helps beat climate change.

Using well managed, sustainable timber is the best option to reduce carbon emissions caused by the building industry. IRON ASH (H3 treated Victorian ash) is PEFC certified and stores carbon for life. In addition, Australian hardwood has one of the best Environmental Product Declarations possible, making it the ultimate renewable.
