Similar to a stockade fence in terms of privacy, a horizontal fence with cap and trim includes “cap” pieces to cover the pickets.
An additional piece of wood, which is flat, runs along the top of the fence, giving it a more polished and refined look for better curb appeal. 
Because the tops of the pickets are protected from rain and moisture, these fences are often highly durable.
