A relatively new material, Timbercrete is a unique blend of cellulose, cement, sand, and binders to enhance block strength and stop excessive water penetration.
Although still an emerging technique – Timbercrete is advantageous enough that it will probably play a role in ongoing sustainable development.
The insulation value of 250mm Timbercrete walls is R1.25 which is almost double the insulation value of brick veneer and cavity brick (without added wall insulation).
Timbercrete is a lightweight composite masonry material invented in Australia, and is available in the form of bricks, blocks, panels and pavers. Made from excess sawmill waste from plantation timbers mixed with sand and binders such as Portland cement and a non-toxic deflocculating additive, it is cured using sun and wind and has a lower embodied energy than traditional fired bricks.– yourhome.gov.au
