When we choose the timber for flooring, the first thing we have to ask is whether the one we are going to use is of good quality. Usually we use the Janka rating as a measure of the wood’s hardness. The higher the number, the harder the wood. Below is the list of the Janka rating for various woods.
| Species Name | Janka Rating |
|---|---|
| Alpine ash | 4.9 |
| Australian Beech | 8 |
| Blackbutt | 8.9 |
| Brush Box | 9.1 |
| Ironbark | 14 |
| Jarrah | 8.5 |
| Spotted Gum | 10.1 |
| Sydney Blue Gum | 8.1 |
| Tallowwood | 8.6 |
| Tasmanian Oak | 4.5-8.0 |
| Bamboo | 7-8 |
