Untreated wood in a few words is basically wood the way it comes from nature. Well, not literally but it isn’t altered. It has no painting, no glue, no nothing. Untreated wood is something that a lot of people look for to avoid health complications. And, as we mentioned, it is valid. But, untreated wood isn’t all that useful for every fence project. Untreated wood comes in handy for temporary projects that need no permits. A small garden fence. A planter. Things that don’t take up a lot of space. These are the ones where untreated wood will work quite well. But, then, what about a proper fence installation? Fencing projects are made with sturdy materials. Which, most of the time involves treated wood or others. Why? To make them last longer.
