Description

Tight Sound Knot

A sound knot is a knot in lumber that is solid and firmly fixed in place, and does not fall out or affect the strength or durability of the surrounding wood. It is a natural occurrence caused by a branch that has been fully encased by the growth of the tree's trunk, creating a tightly knit, dense portion of wood.



Australian Grading Standards

When grading wood in Australia, a sound knot can be classified as sound even when there is partial encasement as long as the partial encasement does not exceed 50% of the knot.


Tight Sound Knot

The maximum KAR for a Face Knot is 50% the width of the timber.

Tight Sound Knot

The maximum KAR for an other Knot is 30% the width of the timber.
