Wood Preservation Treatment
We offer treatment according to client requirements, based on the prevailing standard in different countries, such as CTP, TIM, EN, etc.
Tanalised® Timber - over 30 years of proven performance
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 it durability and enhance its 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, following NTR, EN, BS, CTB P+, and KOMO, along with other recognized Industry Standards.
The dimensions of each of our autoclaves:
- 21 m (diameter 2.6 m)
- 16 m (diameter 2.0 m)
- 14 m (diameter 2.0 m)
- 14 m (diameter 2.0 m)
Several 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 BEFORE treatment
Before the timber is treated its moisture content needs to be at a specific level to allow the wood preservative to penetrate sufficiently during the pressurized 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 protection used
To specify the original Tanalised® Timber, make sure that the timber has been treated with Tanalith® E.
Tanalith® E is authorized 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® E pressure-treated timber has been high-pressure impregnated with the very latest Tanalith® E preservative, a waterborne product based on copper triazole technology. Tanalith® E 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® E pressure-treated timber has an initial natural pale green coloration.
Tanatone® is a brush-on, water-based end-grain timber preservative based on triazole technology. Tanatone® is a dye-based color additive for use with Tanalith® E high-pressure process. The dye in the additive helps to ensure an even initial color strike and distribution giving a medium-quality overall result and a color durability of around 12 months, depending on location and exposure to UV light.
Choosing Tanatone® for Tanalith® E treated timbers eliminates the need for brush-applied color at the point of installation.
Vacsol® 6118 is a low-pressure, water-based wood preservative that is both metal-free and VOC-free. It provides an effective ‘envelope’ of long-term protection against fungal and insect attacks around general building timbers and joinery components.
With a focus on embodied carbon of construction projects, timber treated with Vacsol® 6118 can be reused or recycled at the end of life (subject to local waste regulations).
✔ Vacsol® 6118 has BPR (Biocidal Products Regulation) authorization, passing all necessary environmental, human, and animal health risk assessments.
✔ Vacsol® 6118 is a water-based, metal-free, and VOC-free low-pressure wood preservative. This means timber treated with Vacsol® 6118 can be recycled or reused at end of life (subject to local waste regulations).
✔ As Vacsol® 6118 is a clear treatment, color markers can be added to the low-pressure treatment process to provide reassurance that the timber has been treated.
Our modern, purpose-built factory handles everything in-house - from kiln drying and planning to precision cross-cutting, wood protection, fire retardant treatments, and packaging.
