Because you’re wondering what shadow box fence, I must point out the most obvious first. It has nothing to do with a box. Shadow box fence semi-private actually made by placing a standard picket privacy fence. That have place on both sides of the fence with a space between each picket.
Shadow box fence is usually 6 or 8 feet high but not really personal. When you look directly at them, you cannot see what is on the other side. But, when you look at one of the corner, you can see through it. Unobstructed view, but you can see through them well enough to tell what is happening on the other side. This is because they are built with picket spacing about 2 inches apart on each side of the fence.
Shadow box fence is not really private, but there are some advantages that they have over basic privacy fence that has a picket-stream together. The most obvious advantage is that they are more stylish than a privacy fence base and will set you apart from your neighbors. Basic privacy fence has one side looks pretty and shadow box either from within or outside the fence, they also windproof better than average privacy fence.
