One of the world’s oldest building materials, timber’s physical properties and potential for sustainability are highly regarded. However, when specifying timber for specific applications, the varying properties of different species must be taken into account. The quality and longevity of timber flooring is often perceived to be directly correlated to its Janka rating – the flooring industry’s standard for comparing timber hardness. However, hardness is only one factor designers and specifiers must be aware of when selecting a suitable flooring solution.


Multi-Dimensional: Assessing Quality and Durability When Specifying Timber Flooring takes a closer look at the Janka rating, its limitations and the range of other design considerations that should not be overlooked when assessing timber flooring quality. First, we describe the Janka rating and how it impacts flooring specification. We then consider areas in which it may fall short, such as inaccurate ratings for mixed species and the narrow focus on indentation resistance. Finally, we look beyond Janka and establish performance criteria for timber flooring, highlighting the importance of stability and the timber’s ability to withstand temperature and humidity changes.


Grown locally and sustainably, Tasmanian timber is processed to the highest standards, and backed by the technical support of Australia’s leading timber experts. The premier hardwood for flooring applications, Tasmanian Oak has been the flooring of choice in Tasmania and beyond for more than a century. Designers and specifiers prefer Tasmanian Oak because of its stability and enduring reliability.
