Why choose sustainable?
Sustainable forestry relates to how the timber is being harvested. In Australia, this equates to how many trees are harvested per land area over time. This ensures the longevity of the forest for generations to come. In managed forests where older trees are harvested for wood production (carbon storage), they sequester carbon at a faster rate than unmanaged forests. The certification ensures that the wood specified is sustainably sourced giving you peace of mind.
What is sustainable timber?
Sustainable timber refers to timber that has been harvested responsibly from well-managed forests that are continuously replenished and ensures that there is no damage to the surrounding environment, or to native flora and fauna.
Timber and climate change
Timber has a significantly lower embodied carbon footprint compared to other mainstream construction materials. This is due to the minimal processing required, even when accounting for the process of laminating (glulam or cross-laminated timber) which is generally required to create structural timber products.
If sustainably sourced, using timber can have an additional positive environmental impact because trees absorb carbon dioxide through photosynthesis and lock it away as carbon, thus removing it from the atmosphere. This phenomenon is called sequestration and can essentially offset the processing and transportation energy associated with timber products. Therefore, timber can be considered a carbon-negative material.
How much sustainable hardwood timber is available?
LMA are the New Zealand distributor for Kennedys. Kennedys mill cutting sustainably sourced local hardwoods.
On a recent trip, we went to a Kennedys timber mill whilst they were cutting sustainably sourced local hardwoods (Ironbark and Spotted gum). All of this timber is green, is first dried and then seasoned. The timber, once milled, is strip stacked at Kennedys yard for six months to up to two years to dry naturally. The images below show the scale of the operation and stocks ready to be milled. The reclaimed timber is stored in a number of large yards including beams and square timber at Kennedys. Poles and sleepers are also stored at a further three yards measuring over fourteen acres! Machining, pre-oiling and joinery are all done in-house before being shipped to us in New Zealand for distribution.
