Woodknowledge Timber 101: Quality of timber – Perception and confusion
When we talk about ‘quality’ timber, what are we really saying? The last session of the Timber 101 2026 series breaks down terminology that is often misunderstood and looks into how different perspectives shape views on timber quality.
We will cover:
• The range of timber defects – and which ones matter
• How and when to grade timber
• Confusion around visual vs structural quality
• What architects, sawmillers and foresters each mean by ‘good timber’
By clarifying the differences in how quality is defined and understood, this session will help reduce over-specification, waste and missed value opportunities in timber supply chains.
