Builders have been using timber since ancient times. It’s aesthetically pleasing, durable, and naturally resistant to decay. But not all timber is made alike. Its durability is determined by:
1. The Type of Wood You Choose
Hardwood such as oak can last anywhere between 50 and 100 years. Soft wood such as pine offers a lifespan of 10 to 30 years. Wood hardness is thus one of the most important indicators of durability.
2. Layer Thickness
Thicker timber has a sacrificial layer that takes most of the damage. The underlying layers can thus maintain their structural integrity, and the wood can continuously be refinished.
3. Rot Resistance
The more resistant your timber is to decomposition, the longer it will last.

4. Treatment
Timber treatments enhance durability in several ways, leaving wood more resistant to biological threats and environmental wear. Some untreated timber offers a lifespan of just three years, so look for the hazard class of your materials before making a decision.
5. Environmental Conditions
Timber is highly susceptible to moisture, insects, sunlight, and fungi, so the more humid your environment, the shorter its lifespan will become. Unstable wet/dry weather patterns damage wood by encouraging expansion and contraction. Similarly, UV radiation breaks down timber’s structural components, rendering it more susceptible to moisture.
Timber is an insulating material that offers exceptional heat retention, but treated, well-maintained, thick cuts offer more longevity.
