Timbercrete

 

Timbercrete is an interesting material, being a combination of timber waste (sawdust) from various sources and concrete. This results in a material that is lighter than solid concrete, but of greater strength and with better insulating capabilities.

Some Timbercrete products can produce walls with R ratings of 3.7, which is higher than most other materials except strawbale.

Timbercrete is not a specific type of material, but rather a brand name of timber/concrete composite, and is available in bricks, blocks, pavers and panels.

Because of the fibre content, the material can be screwed or nailed into directly, without the need for special fixings as is required in materials like AAC. The fibre gives it considerable strength, and it won't shatter when impacted like many other materials do.
