Treated Timber
Treated timber is wood that has been appropriately treated with preservative chemicals with the intent of prolonging its intended lifecycle compared to untreated wood.
What is Treated Timber?
Treated timber is wood that has been appropriately treated with preservative chemicals with the intent of prolonging its intended lifecycle compared to untreated wood.
Conversely, untreated timber (sometimes referred to as sawn) is in its natural state, and therefore offers no protection to environmental conditions.
Treated timber is pressure impregnated to guard against environmental conditions.
Treated Timber Class Table:
- Class 1 – Above ground, covered. Permanently dry, risk of insects.
- Class 2 – Above ground, covered. Occasional risk of getting wet.
- Class 3a – Above ground, coated. Exposed to frequent wetting.
- Class 4 – In contact with the ground or fresh water. Permanently exposed to wetting.
Which Treated Timber Method?
The types of preservation system available are;
- Protim – an organic system that pressure treats timber used in construction projects, where the required protection is to Class UC1, UC2 and UC3. When using Protim in an external environment it should be coated with an external coating.
- Celcure preservation system is used for wood that has been treated with an Osmose preservative system. It also preserves the timber to Classes UC1, UC2, UC3 and UC4.
- MicroPro – is a preservation system is also used for timber that has been treated with Osmose. It again protects the timber to Classes UC1, UC3 and UC4
Different types of applications and preservatives are used to protect wood fibers from:
- structural degradation
- decay fungi
- termites
- marine organisms
- flames
Comparison of untreated wood vs. treated wood:
- Because treated wood is intended to extend the usefulness and life of wood, fewer trees are required to perform the same function that is required when untreated wood is used.
- Wood that has been appropriately treated can significantly reduce the number of trees that would otherwise need to be harvested.
- If untreated wood only lasts 5 years and treated wood lasts 25 years or more, it would take at least 5 times as many trees over the same period of time, as well as the incremental labor, to continually harvest, manufacture, replace and dispose of all of the untreated wood.
- Unprotected wood can begin to rot within 1-2 years depending on the environment.
- The structural integrity of untreated wood can be greatly reduced within weeks due to termites and certain marine organisms.
- Without chemical treatments, wood can be quickly consumed when exposed to flames.
The best way to protect and preserve wood, including timbers that have been tanalised or pressure-treated is to use a wood preservative.
Treating your wooden products should be treated as a priority, and depending on your local conditions and wood type this may need to be done from once every 3 months, to once every 12 months.
