What is 'ACQ',
Tanalith 'E' or 'pressure-treated' timber?
It is a wood preservative treatment that protects against decay fungal /insect
It is a treatment that is much more friendly to people and the environment,
than Creosote, that was banned in 2003. See
~ The timber is treated using pressure impregnation with a water based preservative,
complying with BS 4072
~ Treated timber has a green or natural pine colour.
~ When impregnated into the timber the chemical components become fixed within
the wood structure and are leach resistant.
~ Usually specified for general construction and outdoor timbers
How long does it last?
Believe it or not,
the treatment companies (and hence us!) offer NO
at all as to the treatment and the longetivity of the timber. They
argue that the way timber is used and constructed is in so many different
applications and settings (above ground, under ground, in water etc...) not
to mention timber naturally splitting and moving, and being cut, drilled into
etc.. that they cannot guarantee or predict how long the
timber will last and how long the treatment will be effective.
Sitting on the fence
In reality, like many companies, they are frightened about
people making claims against them, and so chose to offer
no guarantee, rather than risk someone wanting the whole of their fencing
to be replaced after 10 years, if it starts to rot.
Although we all know that pressure treated timber will last
considerably longer than 2 days (!) we are unable to say or guarantee how
long it will last. Sorry.It's all very unsatisfactory, but it's the way of
the world !
