We installed this 100% cedar board on board or shadow-box fence recently in Fair Haven, NJ. This fence is a replacement of an older wood fence that was in dis-repair. This type of cedar wood privacy fence is constructed with two overlapping layers of vertical boards attached to horizontal rails, creating a visually pleasing and robust barrier. The fence typically consists of 4” or 6” wide boards, leaving a 2” to 3″ gap between each board on either side. Posts are 4”x4” pressure treated and rated for ground contact. This entire fence was designed and custom fabricated by Add A Link Fence Company.
