Defects in Wood
Saturday, 12 April 2008 08:43

The term defects refers to irregularities found in wood. And the most common defects in wood are:

1. Caused by Abnormal Growth such as:

a. Heart Shakes - are radical cracks in wood originating from the heart of the logs. Heart shakes are commonly found in old trees.

b. Wind Shakes or Cup Shakes - are cracks or breaks across the annual rings of the wood during its growth caused by extensive bending of the tree due to strong wind.


c. Star Shakes - are composed of several heart shakes which radiate from the center of the log in a star like manner.

d. Knots - occurs at the starting point of a limb or branch of the tree.

2.  Due to Deterioration

a. Dry Rot - is caused by fungi in a seasoned lumber due to the presence of moisture.
b. Wet Rot - takes place sometime in the growth of the tree caused by water saturation.
