Wood Preservation Treatment
We offer treatment according to client requirements, based on the prevailing standard in different countries, such as CTP, TIM, EN, etc.
The ecological benefits of pressure-treated wood are evident in its carbon-neutral wood raw material, and long product lifespan. The long lifespan of durable wood reduces the use of forest resources, transportation needs, and the resources required for repairing structures.
The quality and durability of timber depend on the correct choice of wood preservatives. To increase the durability and enhance the various properties, Lotus Timber uses the best available scientific technology to treat timber. We offer treatment according to client requirements, based on the prevailing standard in different countries, such as CTP, TIM, EN, etc.
Lotus Timber uses industry-recognized products from Arxada - Tanalised® Timber protection (an international market leader in timber preservation). These products offer full protection for various species of wood against fungal decay and insects. As many of our treated products are taken back to nature, in the countryside, forest, and gardens, we use the environmentally friendly Tanalith E 3475 wood preservative, which is an efficient alternative to Creosote oils.
Lotus Timber is the sole representative of Arxada in Estonia.
We offer timber preservation and treatments using our four autoclaves, in accordance with NTR, EN, BS, CTB P+, and KOMO, along with other recognized Industry Standards.
The dimensions of each of our autoclaves are:
- 21 m (diameter 2.6 m)
- 16 m (diameter 2.0 m)
- 14 m (diameter 2.0 m)
- 14 m (diameter 2.0 m)
We offer the following pressure treatments in our four autoclaves:
The treater should have quality controls in place to check that the timber is treated to the standard expected. A number of factors contribute to the overall performance of industrially treated timber. The list below provides a summary.
Timber species
Some softwood timber species are more receptive than others to timber treatment.
End-use application (Use Class)
For fence posts it's crucial that you only specify timber that is treated to Use Class 4 (in ground contact).
How the timber is prepared prior to treatment
Before the timber is treated it's moisture content needs to be at a specific level to allow the wood preservative to penetrate sufficiently during the pressurised treatment.
The timber treatment process
The treater should have quality controls in place to check that the timber is treated to the standard expected.
The wood preservative used
To specify the original Tanalised® Timber, make sure that the timber has been treated with Tanalith® E. Tanalith® E is authorised under the Biocidal Products Regulation (BPR). Formulations hold national approvals across Europe including the WPA Benchmark Approved Formulation, NTR NWPC and FCBACTB-P+ scheme.
TANALITH pressure-treated timber has been high-pressure impregnated with the very latest Tanalith preservative, a waterborne product based on copper triazole technology. Tanalith pressure-treated timber is usually specified for both in and out of ground contact applications where there is a medium to high risk of decay or insect attack. Tanalith pressure-treated timber has an initial natural pale green coloration.
ENSELE TANALISED and ENSELE TANATONE are brush-on, water-based end-grain timber preservatives based on triazole technology. They are designed for the re-treatment of exposed cross-cut, notched, or drilled surfaces of Tanalith and Tanatone pressure-treated timbers. Ensele helps to maintain the integrity of the pressure-treated timber against fungal and insect attack.
