Resistance against impact |
|
|
The surface of
the wood flooring is constantly exposed to
physical impact such as scuffs, scratches
and knocks. There are differences between
wood floorings when resistance to scuffs and
knocks is considered. This is mainly due to
differences in the hardness of the wood
species used for manufacturing top layer
lamina. As a main rule the higher the
Brinell-hardness the more durable the
lamina.
Please note that none of the above mentioned
wood species is able to bear excessively
heavy point loads without damage, such as
the concentrated load of furniture feet not
having protective felt pads. On the other
hand it is natural that in the course of
time wood flooring will have small dents and
marks as part of its patina.
In this table the average hardness degree of
timber materials has been compared to
surface lamina of Karelia parquetry:
