Will tanalised timber twist in hot dry conditions?

no


Can tanalised wood be painted?

TANALISED timber relates to timber that has been industrially treated with TANALITH preservative under vacuum in an enclosed treatment vessel. The preservative manufacturer, Arch Timber Protection, has a website at www.archtp.com with a Consumer Information Sheet which contains advice regarding compatible glues for TANALISED E pressure treated timber. A range of glues are advised, depending on the end use of the treated timber.


What are the blue marks on tanalised timber?

The blue marks on tanalised timber are caused by the copper-based preservative treatment used to protect the wood from decay and insects. These marks are a normal occurrence and do not affect the structural integrity or performance of the wood.


Will tanalised timber split?

Tanalizing, an impregnation with a copper chrome arsenate, only improves the timber's durability. Whilst the timber is wet, its splitting tendency will be reduced.


Does tanalised timber protect from dry rot?

It will help, but the best way to prevent dry rot is to keep timber dry and to ensure it gets enough ventilation.


Can you get arsenic poisoning from handling Tanalised wood?

Tanalised timber refers to wood that has been industrially treated using a controlled vacuum pressure process with the Tanalith preservative.Tanalith C preservative contains chromated copper arsenate. In Europe, the use of Tanalised C pressure treated timber was restricted in 2006, and its successor in this market is Tanalised E pressure treated timber, which contains copper and triazole biocides.Timber treated with any Tanalith preservative is resistant to leaching but should be handled with care and any exposed skin is recommended to be washed before eating, drinking or going to the toilet. Avoid handling treated timber that is wet.See the Related links for more information.


What will happen to your health if you burn tanalised timber in an open fire?

Tanalised timber refers to wood that has been industrially treated using a controlled vacuum pressure process with Tanalith preservative. Tanalised and Tanalith are registered trade marks of Arch Timber Protection, and may not be used to describe other formulations.Tanalith C preservative contains chromated copper arsenate (CCA). In Europe, the use of Tanalised C pressure treated timber was restricted in 2006, and its replacement there is Tanalised E pressure treated timber, which contains copper and triazole biocides - which are commonly used to protect food crops.The options for disposal of Tanalised wood are dependent on the formulation of Tanalith preservative that the timber was treated with, which can be identified by analysis. The Code of Practice in Related Links gives recommended advice on how treated timber can be disposed of effectively.Tanalised E may be burned in approved industrial incinerators, but should not be burned in open fires or home wood burners. Please see the Related Link for more detailed information.When burned, Tanalised C or CCA treated timber releases toxic chemicals into the air and concentrates them in the ash. The treatment of this timber may incorporate Copper, Chrome and Arsenic. These can all be classed as heavy metal toxins. Symptoms will vary depending on the degree of poisoning but can include:loss of appetite,nausea,vomiting,diarrhoea,skin tingling,cramping of muscles,seizures,hearing loss,sleepiness,confusion,headaches,fainting,dizziness.


Is tanalising an oil based or water based wood treatment?

TANALISED pressure treated timber has been impregnated with TANALITH E, a waterborne product.


How do you tanalise timber?

Timber is 'TANALISED' (treated) in an industrial treatment vessel using TANALITH preservative applied using vacuum pressure technology. TANALITH and TANALISED are registered trade marks of the preservative manufacturer, Arch Timber Protection, and may only be used to describe industrial timber treatment using TANALITH preservative. The treatment process consists of 5 stages: 1. Timber is loaded into the treatment vessel. An initial vacuum is applied, and the timber cells are evacuated of air. This vacuum is held. 2. The cylinder is flooded under vacuum with TANALITH wood preservative. 3. Hydraulic pressure is applied, forcing the preservative deep into the structure of the timber. 4. A final vacuum extracts excess preservative solution, which is then pumped back into storage. 5. Low pressure inside timber draws in surface solution when vented to atmosphere. The treated timber is then left to dry - a minimum holding time of 48 hours is recommended. In Europe, TANALITH E preservative is used, which contains copper and triazole biocides, which are commonly used to protect food crops. TANALISED E pressure treated timber can be used in a range of applications, from construction timbers through to heavy duty, highway fencing applications, where a desired service life of 15 years plus can reasonably be expected. Note that where TANALISED treated timber is cross cut, notched or bored following treatment, liberal coating of ENSELE end grain preservative is required to maintain the integrity of the preservative system. Further information on TANALITH E and the treatment process can be found on the Arch Timber Protection website at www.archtp.com. General information regarding timber treatments is available on the Wikipedia site: http://en.wikipedia.org/wiki/wood_preservation

Can you burn tanalised wood in your fire?

When a component treated with TANALITH wood preservative, applied using a vacuum pressure treatment process, reaches the end of its useful service life, there are a number of methods to consider for its disposal. These options are dependent on the formulation of TANALITH preservative that the timber was treated with.

What is 'tanalised' wood?

'TANALISED' timber has been impregnated with a preservative solution under high vacuum pressure in an industrial vessel. This treatment process ensures deep penetration into the timber cells, for a longer-lasting protective result against fungal decay and insect attack than the application of a surface coating. Pressure-treated timber is leach resistant, ensuring a long and trouble-free service life in a wide range of conditions, and assured performance in sensitive environments such as vegetable plots and areas of wildlife. Desired service lives range from 60 years for internal timbers and 30 years for external timbers such as fence posts in ground contact. The treated timber initially assumes a green colouration, which fades to a honey brown over time and eventually a silver grey. No surface applied product is needed to maintain the integrity of the treatment. Timber treatments are specified in line with BS8417, in order to ensure that an appropriate level is given according to the end use of the timber. The Use Class system is an indicator as to how the timber should be treated in order to match its end use. In the UK, 'TANALITH E' is the latest generative preservative, utilising a copper azole formulation which incorporates biocides that are also used to protect food crops. 'TANALISED', and 'TANALITH' (the preservative) are both internationally registered trade marks of the preservative manufacturer, Arch Timber Protection. These brands have been established since the 1940s, and are a key signature of treatment quality. An alternative to high-pressure treatments is VACSOL, which is a product applied under low pressure to create an envelope seal of protection. VACSOL Aqua is a water-based formulation, commonly used in the UK and across parts of Europe, and can impart a 60 year desired service life against fungal decay and insect attack for constructional timbers.
