Sustainability
On a holistic level, our GoodWood is one of the best options once you include carbon sequestration, life cycle analysis, harvesting and regeneration.
Only 6% of Victoria’s total forest area is both suitable and allocated for harvesting and regeneration on an 80 year cycle. Less than 0.05% of the forest area is harvested each year (yes, that decimal point is in the right place). It is then regenerated. Not only that, but 100% of each log we receive is used by utilising off-cuts to make finger jointed products and using the sawdust as a carbon neutral green energy solution to power our kilns.
GoodWood is ASH’s brand of Victorian ash and Tasmanian Oak. GoodWood was created so architects and designers get reassurance during specification that they’re getting a quality, consistent product all from ASH. So don’t forget to put the ‘GoodWood’ before Victorian ash or Tasmanian Oak!
Victorian ash is an Australian hardwood made from two species of Eucalypt – Alpine Ash and Mountain Ash. GoodWood is a timber that’s internally scanned for defects, graded to high standards, straight line edged, stable with consistent moisture content, grain and colour and can be matched with the rest of ASH’s products.
Tasmanian Oak and Victorian Ash come from two near identical eucalypt species, E. Delegantensis and E. Regnans. Although they share many similarities, including species make up, there are some minor differences between Victorian ash and Tasmanian oak.
Tasmanian Oak can be one of E. Regans, E. Delegatensis & E. Obliqua (Mountain Ash, Alpine Ash & Messmate). The younger growth tends to be lighter in colour while the older trees can be darker across the spectrum. This is what gives Tasmanian Oak hardwood the larger variation in colour.
Both species are suitable for many of the same applications and are quite easily used in unison.
Yes, Victorian ash and Tasmanian Oak can be used for external applications when treated to H3 classification. See the IronAsh page for more detail.
