Building a fence is a major undertaking, with many factors to be considered such as price, durability and appearance. According to the Seattle Times, one factor that should be a priority is the environmental impact of materials. With the right research, you could be lucky enough to find yourself with a fence that takes into account all four of these factors.
The greenest fence of all is no fence, but that’s not always an option when you have small children, pets or require a bit more privacy.
Salvaged materials: The next best option to no fence is to use salvaged materials, which in some cases can be free. The problem is that finding the right amount of a consistent material can sometimes prove difficult. The plus is that when you do find enough, a salvaged fence can look eclectic and quirky.
Wood: Timber is the number one choice for fences in Australia, with its aesthetically pleasing classic look. The problem is that wood is susceptible to rot, so timber must be treated.
Metal: Not only does metal offer a wide range of choices, it is low-maintenance and reusable. The problem is that it can be expensive and prone to rust if not cared for properly.
Stone and Brick: A stone or brick wall is solid, but it can be time-consuming to construct. Salvaged stone or brick is the perfect option for an environmentally-friendly fence.
