What is natural defect in timber?

Natural defects in timber refer to inherent imperfections that occur in wood due to its biological origin and growth conditions. Common examples include knots, splits, warping, and discoloration, which can arise from factors like tree growth patterns, environmental stress, or insect damage. These defects can affect the strength, appearance, and usability of the timber, making it important for woodworkers and builders to assess and account for them in their projects. Understanding these natural defects helps in selecting the appropriate timber for specific applications.
