Board to board siding application is the most common original application we see, and therefore, very authentic; boards are simply attached side by side either vertically or horizontally; just about any of our siding products can be installed this way, but the appearance and design can vary widely; boards with lots of color variation from board to board can be used or product can be selected to have as little color variation from one board to another; random width boards can be used or boards of all the same width or a repeating pattern of sizes; vertical and horizontal applications can be mixed-for example vertical above and below window and doors with horizontal in between or vertical on body and horizontal on the gables etc, etc; in short, board on board applications can be designed in too many ways to mention and allow an architect, designer or craftsman much flexibility to create a unique look with a basic product.
