Is there a difference between Green and Brown timber?
As mentioned, the only difference between Green and Brown timber is the Brown dye used during preservation - this does make Brown timber slightly more expensive to buy.
So, when a product is referred to as ‘Green timber’ you’ll know that it’s been treated but left in its natural colour.
What is treated timber fencing?
We’ve mentioned that Green and Brown timber are both treated (also known as tanalised), but what does this actually mean?
Treated timber is wood that has been dipped in chemicals to help prevent insect damage, decay, rot and fungal attacks. Especially useful where timber is exposed to the elements and moisture. The treatment extends the longevity of the fencing, and is highly recommend over untreated timber.
Left in their natural, unfinished state, timber products can deteriorate quickly when exposed to outdoor environments.
When treated, Green and Brown timber are typically labelled with a ‘UC3’ or ‘UC4’ rating, with UC4 being a more vigorous and penetrative treatment than UC3.
But what’s the difference when it comes to use for fencing?
UC3 timber is treated enough to be used outdoors, but should be above ground and not in contact with the ground (e.g fencing panels). Whereas, UC4’s more vigorous treatment allows for permanent contact with the ground (e.g fence posts).
