Properties of good timber

A number of factors affect the quality of timber. The following constitutes what to look out for when considering quality timber:

1. Straight & Compact Fibres: The fibres of quality timber should be straight and firm.

2. Strength: Good quality timber should have the strength to resist heavy structural loads.

3. Durability: It should be able to resist atmospheric effects, and also attacks of fungi and worms, for a longer period of time.
