Accoya Gates & Garage Doors

Unlike tanalised softwood, where the treatment usually only penetrates a couple of millimetres into the timber, with Accoya, the treatment goes right the way through to the core of the timber.
As a result of the acetylation process, the Accoya is warrantied for fifty years when used and installed in a position not in contact with the ground. If the Accoya product is in contact with the ground when installed, then the warranty is twenty-five years.
Accoya is a timber of the future, and best of all it grows on trees!
Basically, in plain speak, the timber is treated with Acetic acid; this causes the chemical structure of the timber to change in such a way that the timber cannot absorb any moisture, therefore meaning the timber cannot rot. As well as increasing the timber s durability, the fact that the Accoya cannot absorb moisture also makes the timber a lot more dimensionally stable too!
The acetylation process also increases the hardness of the timber and also increases the timber s resistance to UV damage, and before you ask, the treatment is totally non toxic it really is a wonder timber!
The one drawback, if I can call it that, is with either Accoya gates or Accoya garage doors then it is recommended you use stainless steel ironmongery rather than galvanised or black ironmongery. As with Oak gates and garage doors, the acids present in Accoya will corrode both the black and galv. ironmongery this will then stain your gates or doors. For best results, use A2 or A4 grade stainless steel hardware/ironmongery and fixings. Naval brass can also be used but avoid Galv., black or zinc plated ironmongery/hardware and fixings.
Accoya can be either painted or stained like normal timber, drying times for your chosen finish can be longer than for other timber. If staining the timber then we need to know at the point of order as Accoya can suffer from some black staining (a side effect of the acetylation process but no detriment other than visual) which can show the stains (but not paint!). If staining our Accoya gates they then generally finish at 65mm thick (rather than our usual 70mm) so we can remove all the black, for garage doors we usually have to use the next thickness of timber up (58mm thick) to get a stain free 45mm finish.
