Hardness
Depending on whether your hardwood floor is for commercial or
domestic use, you might want to consider the hardness of the timber
you choose. Generally, hardwood floors have a janka rating of
5 and above, suitable for commercial and heavy traffic.
The Janka rating system
This system is a quantified measure of the hardness of timber.
It measures the force needed to drive a stell ball to a depth
where half the ball is imbedded in the wood. The more resistant
the timber, the higher the Janka rating
Durability
The term "durability" refers to the natural
ability of the hardwood to resist attack from biological hazards
such as fungal attack or in high-risk conditions such as low ventilation
or high humidity.
The durability clasess are:
Class 1 - highly durable
Class 2 - durable
Class 3 - moderately durable
Class 4 -non - durable
